Nathan discovered within the first month that there was a difference between being ignorant and being slow.
He had confused the two for most of his life.
Ignorance had always seemed like a permanent quality when he was younger, something carved into a man by the circumstances of his birth. There were boys who went to school and boys who worked. Boys who learned Latin and boys who learned how to tell whether a constable had noticed them. Boys who worried about examinations and boys who worried about where the next meal would come from. Nathan had belonged to the latter long before Africa, and though he had stolen education wherever he could—books borrowed and never returned, scraps of lessons overheard from men wealthier than himself, a handful of patient people who had been willing to explain something because a hungry boy had asked the right question—he had never mistaken that patchwork for what men at University College possessed.
The mountain had made the patchwork stranger.
Harcourt remained somewhere inside it. So did Hargreaves. Ward contributed little academically but appeared unexpectedly whenever military matters were raised. There were others too, men whose names Nathan sometimes remembered only after one of their memories surfaced. The dead did not speak to him. That would almost have been comforting, because voices could be dismissed as madness. Instead Nathan simply knew things he had never personally learned. A Latin construction might appear familiar because another boy, decades earlier, had once bent over a desk and cursed the same sentence. A theorem could awaken the sensation of chalk between fingers Nathan had never possessed. Sometimes he remembered the smell of a classroom before he remembered the rule that had been taught inside it.
Those fragments had impressed Platt during the examination.
What astonished him afterward was how quickly Nathan joined them together.
Professor John Arthur Platt had approached Nathan's education with the careful pessimism of a man accustomed to enthusiastic students grossly overestimating themselves. His first schedule had been almost merciful. Latin would be regularised rather than merely recognised. Nathan's mathematics would be put into proper sequence. English composition needed what Platt called discipline and Nathan privately called interfering. Chemistry would be strengthened because the scientific subjects Nathan wanted eventually to pursue could not be built upon enthusiasm alone. The work was supposed to occupy months.
Nathan began damaging the schedule almost immediately.
One cold morning Platt entered the room they were using and found Nathan already there, seated beside the window with an open notebook, three completed exercises and yesterday's book lying closed beneath his hand. Rain made wavering lines down the glass beyond him. Nathan had been listening to it while working, not because the sound helped him concentrate but because he was still teaching himself to ignore the hundreds of human bodies moving through nearby corridors. A heartbeat was simply a heartbeat. Footsteps were simply footsteps. The cough two rooms away did not require analysis.
Platt removed his gloves and noticed the paper markers sticking from the book.
He stopped.
"I assigned three chapters."
Nathan looked up. "Yes."
"There are markers in chapter eleven."
"Yes."
Platt picked up the book as though Nathan might have physically injured it. "Why?"
"The seventh chapter referred to something in the eighth."
"That happens."
"I wanted to know what it meant."
"So you read the eighth."
"Yes."
"And then?"
"The ninth was next."
Platt stared at him.
Nathan waited.
"You understand that an assigned portion is generally intended to indicate where a student should stop?"
Nathan frowned faintly. "Why?"
Platt's mouth opened and then closed again.
Nathan, realising too late that the question sounded more insolent than curious, added, "I finished the other work first."
"You finished—"
Platt looked toward the papers.
"Latin?"
Nathan slid one sheet across.
"Mathematics?"
Another.
"Your composition?"
Nathan tapped the final pages.
Platt slowly sat.
"Drake."
"Yes?"
"If you have rushed through this because you are impatient to reach physiology, I will personally make certain you spend another month conjugating verbs."
Nathan's expression tightened. "I didn't rush."
"You read approximately half a book in one evening."
"I read all of it."
Platt stared.
Nathan realised that had not helped.
Platt opened the book at random. "Very well. Explain this."
Nathan did.
Platt allowed him perhaps three minutes before interrupting and moving somewhere else in the text. Nathan answered that too. The questions became less predictable. One demanded that Nathan explain an argument rather than repeat it. Another required him to connect an earlier chapter with one near the end. Nathan did well until Platt found a distinction Nathan had misunderstood and caught him trying to reason through it by instinct.
"No," Platt said.
Nathan stopped.
"No?"
"No. That is incorrect."
Nathan looked at the passage again. He felt the familiar irritation rise, the primitive instinct that still treated being wrong as being threatened, and forced it down.
"Why?"
Platt explained.
Nathan listened without writing. When Platt finished, Nathan frowned and said, "Give me another example."
"I have just given you the rule."
"I know the rule now. I want to know whether I understand it."
Something changed in Platt's face.
He gave him another.
Nathan answered correctly.
Platt altered it.
Nathan took longer, but answered again.
A third example required him to abandon the pattern of the first two and actually apply the principle. Nathan stared at it for perhaps forty seconds before tapping one part of the sentence.
"This changes it."
Platt sat back.
Nathan looked up.
"What?"
"You did not know that five minutes ago."
"No."
"And now you do."
Nathan waited for the rest of the question.
There wasn't one.
"Is that unusual?"
Platt removed his spectacles and rubbed the bridge of his nose. "Increasingly, I am discovering that asking you that question is dangerous."
That morning became the first of many in which Nathan's tutors found themselves teaching considerably more than they had prepared.
The speed itself would have been merely impressive if Nathan had only memorised what he was shown. Platt knew men with extraordinary memories. University libraries had their share of students who could recite a page almost word for word and then become helpless when asked to use the information in a form they had not previously encountered.
Nathan was different.
Knowledge rarely stayed where someone put it.
A mathematical method explained in one context would appear the next day inside another problem where no tutor had told Nathan to use it. A correction to his Latin would send him hunting through texts for the same construction. Chemistry became almost infuriating because each answer produced three more questions. Explain that heat altered the rate of a reaction and Nathan immediately wanted to know whether enough heat altered the products themselves, then how pressure would change matters, then whether the same result could be expected if one reagent were replaced with another of similar properties.
One of his mathematics tutors lasted less than two months before openly complaining to Platt in the corridor.
Nathan heard the conversation from inside the room and tried not to listen.
Then he heard his own name.
Listening became unavoidable.
"I gave Drake enough work to occupy him until Friday."
Platt's voice came after a pause. "Today is Wednesday."
"Yes."
"And he has not done it?"
"He has finished it."
Nathan looked at the door.
"I am failing to see the emergency."
"He returned it this morning."
Platt sounded suspiciously amused. "Perhaps he began immediately."
"I gave it to him yesterday afternoon."
Nathan opened the door before the discussion could become any stranger.
Both men turned.
Nathan leaned against the frame. "You told me it was due Friday."
The tutor looked at him as if he had personally designed the problem. "Yes."
"I finished it before Friday."
"It was intended to last until Friday."
"You should have said that."
Platt looked away.
The tutor noticed.
"Do not encourage him."
"I assure you, I have spent weeks attempting the opposite."
The tutor drew one of Nathan's papers from the bundle. "You have made an error here."
Every trace of amusement disappeared from Nathan's face.
He came out immediately. "Where?"
The man pointed.
Nathan bent over the page. It was nothing profound, merely a sign carried incorrectly after several lines of otherwise sound work. Nathan read backward, found the mistake, took the pencil the tutor offered and corrected the calculation.
"That changes these."
He rewrote the following lines.
The tutor waited.
Nathan reached the corrected result.
"There."
The man looked at the paper.
Nathan looked at him.
"Is there another?"
The tutor slowly turned toward Platt.
Platt sighed with the resignation of a physician acknowledging an incurable condition.
"Give him harder work."
Nathan smiled.
The gaps Platt had expected to spend the better part of a year repairing became smaller by the week. There were still moments in which Nathan encountered embarrassingly basic things he had somehow missed, but those became useful rather than humiliating. University College was teaching him something prison, poverty and Africa never had: being wrong did not necessarily carry punishment.
Sometimes it only meant there was something new to learn.
Nathan began almost looking forward to it.
By spring, Platt ceased asking whether Nathan could manage higher study and instead began wondering how quickly Nathan should be allowed into the subjects he had requested. That argument was eventually settled when Nathan produced a timetable.
Platt stared at it.
Then stared at Nathan.
"No."
Nathan sat on the opposite side of the desk with his hands resting calmly in his lap. "Nothing overlaps."
"I am not rejecting it because I fear you will physically occupy two lecture rooms simultaneously."
"Then why?"
"Because those are bacteriology, physiology, pathology, zoology and general biology."
"Yes."
"Together."
"Yes."
"Drake."
Nathan waited.
Platt rubbed two fingers against his forehead. "Men spend entire careers studying one of these."
"I intend to spend longer than a term."
"That is not reassuring."
Nathan leaned forward and turned the timetable slightly so Platt could see it better. "The bacteriology instruction is comparatively short. Biology overlaps with material I'll need for the others. Pathology and physiology—"
"I can read."
Nathan stopped.
Platt looked at him. "Why must you do all of them at once?"
Nathan had several answers.
The honest one was that he did not know how long he would remain free before someone noticed what he was.
Another was that ignorance regarding his own body had become intolerable.
He gave Platt the safest.
"Because they answer different parts of the same question."
Platt's expression sharpened slightly.
"What question?"
"How living things work."
It was close enough to truth.
Platt leaned back.
"And if you fail?"
"I drop one."
"Which?"
"The one I'm failing."
"And if you begin falling behind everywhere?"
"Then you choose."
Platt stared at him.
Nathan knew he had found the opening.
"One term."
"No."
"One."
"You will exhaust yourself."
"I sleep."
Platt's eyebrows lifted.
Nathan amended, "Regularly."
"That pause was deeply concerning."
"One term."
"Drake."
"If my marks suffer, you choose what I stop. I won't argue."
"You will argue."
"I won't refuse."
"That is a more believable promise."
Nathan smiled.
Platt eventually agreed.
He expected to exercise the condition before the term ended.
He never did.
Bacteriology caught Nathan first.
The laboratory was less dramatic than he had imagined when reading about Pasteur and Koch. There were no revelations waiting theatrically beneath every microscope. There was glassware, stains, cotton plugs, cultures that required patience and techniques where a careless finger could invalidate hours of work. The discipline offended Nathan's preference for speed.
Then he contaminated a preparation.
Sidney Harris Cox Martin found him standing over it long after Nathan should have accepted the failure and moved on.
"What happened?"
Nathan answered without looking up. "Contamination."
Martin waited.
Nathan finally glanced toward him.
"What?"
"That is the name for the result."
Nathan frowned.
Martin came closer. "What happened?"
"Something got into it."
"What?"
"I don't know."
"How?"
"I don't know."
"When?"
Nathan's annoyance deepened. "I said I don't know."
Martin nodded.
"Good."
Nathan stared at him.
Martin's expression did not change.
"You are pleased?"
"Very."
"Why?"
"Because for once you have reached the correct answer without trying to sprint past it."
Nathan looked back at the spoiled preparation.
Martin rested one hand against the bench. "You will ruin yourself in this field if you become afraid of those three words."
"I don't know."
"Yes."
"I dislike them."
"I had noticed."
Martin picked up the culture. "A foolish man sees an unexpected result and invents an explanation immediately because uncertainty embarrasses him. A better man asks what can actually be established. Was the medium contaminated before you began? Was your instrument unclean? Did something enter from the air? Did you mishandle it? Is the organism you see even contamination at all, or did your original assumption fail?"
Nathan looked at him.
"You don't know either."
"No."
Nathan considered that.
"How do we find out?"
Martin smiled faintly.
"That is why you are here."
Nathan never forgot the exchange.
For months he had been committing precisely the error Martin described with himself.
The thing beneath the mountain had infected him.
Perhaps.
It had fused with him.
Perhaps.
Nathan had consumed it.
Perhaps.
It had consumed Nathan and merely retained him.
Perhaps.
Every theory sounded convincing because none could be tested.
Bacteriology taught him to hate explanations unsupported by experiment.
He completed the formal short bacteriology course offered to him in 1899 faster than anyone involved had expected, but finishing the course proved meaningless to Nathan. The practical requirements gave him tools. What interested him lived at the edges, where those tools failed.
That was where he encountered Ivanovsky.
The experiment had been conducted seven years earlier, in 1892, while Nathan was still an entirely human young man and the African mountain had yet to become anything more than an unknown place on another continent. Dmitri Ivanovsky had taken sap from tobacco plants suffering from mosaic disease and passed it through filters fine enough to retain known bacteria.
The filtered sap remained infectious.
Nathan sat over the account for a very long time.
The filter stopped bacteria.
The disease went through.
He followed the work forward until he reached Martinus Beijerinck in 1898, only the previous year. Beijerinck had repeated and developed the observations and argued that whatever caused the tobacco disease was not behaving as an ordinary bacterium. It passed through the filters. It propagated only in association with living tissue. He described the infectious principle as a contagium vivum fluidum, and the old word virus was beginning to gather around an entirely new category of unseen infectious agents.
Nathan read the account until the laboratory around him emptied.
He did not notice the change until Martin returned and found only one lamp still burning.
"Are you planning to sleep here?"
Nathan looked up.
"What time is it?"
Martin checked the clock. "Late enough that this question supports my concern."
Nathan tapped the paper.
"This remained infectious."
Martin followed his finger.
"Ivanovsky."
"And Beijerinck."
"Yes."
"The filters should retain bacteria."
"They retain the bacteria we know."
"Then whatever passes through is smaller."
"Possibly."
Nathan gave him an irritated look.
Martin sat opposite him.
"You hate cautious language."
"It wastes time."
"It prevents stupidity."
Nathan turned the paper around. "It propagates in living material."
"So Beijerinck argues."
"But it doesn't grow on ordinary media like a bacterium."
"No."
"Then what is it outside living tissue?"
Martin was quiet.
Nathan waited.
"Alive?"
"We don't know."
"Dead?"
"We don't know."
"Something between?"
"That may be a distinction created by the limitations of our language rather than by nature."
Nathan went completely still.
Martin saw the change but misunderstood it as intellectual interest.
Nathan looked down again.
"A thing that isn't properly alive until it is inside something alive."
"That is going farther than the evidence."
"I know."
"You continue doing it."
Nathan smiled faintly.
"Could it alter the host?"
"Obviously. Disease alters hosts."
"I don't mean simply injure it."
Martin's attention sharpened.
Nathan chose his next words carefully.
"Could an infectious agent make cells produce something they otherwise wouldn't? Force the tissue into a different state?"
Martin considered him for several seconds.
"We know very little about how such an agent acts, particularly one we cannot observe directly."
"So it is possible."
"Almost anything is possible when evidence has not yet excluded it."
Nathan sighed.
Martin smiled.
"Evidence first."
"Evidence first."
Nathan folded the paper.
The word virus followed him home.
It did not explain him.
Whatever lay beneath the mountain had existed without an obvious host for periods Nathan could not meaningfully comprehend. It could think—or at least Nathan could think. It could alter entire organisms, retain forms, retain memories, remain beneath rock for ages and then rise through him.
But science had already discovered one thing Nathan found enormously reassuring.
The invisible world was larger than men had believed.
That meant the map was unfinished.
While bacteriology drove him inward toward things too small to see, physiology forced Nathan to confront the body everyone around him believed he possessed.
Ernest Starling took the physiology chair at University College in 1899, and Nathan soon discovered that Starling was almost perfectly designed to irritate him.
Their first serious disagreement began when Nathan completed an experimental calculation correctly.
Starling looked at the figures.
"Why?"
Nathan frowned.
"The figures are there."
"I can see them."
"They show the change."
"I asked why it changed."
Nathan pointed toward the page.
Starling did not even glance down. "That is arithmetic."
"It is correct arithmetic."
"I am delighted for the arithmetic. Now tell me what happened in the animal."
Nathan's jaw tightened.
He began describing the experiment again.
Starling interrupted whenever he substituted a measured value for a physiological explanation. The first time Nathan thought the interruption unnecessary. The second time he became annoyed. By the third he realised what Starling was demanding.
He stopped looking at the paper.
Pressure.
Resistance.
Flow.
Tissue response.
One change leading into another.
When Nathan finally finished, Starling nodded.
"Better."
Nathan stared.
"Better?"
"Yes."
"That is all?"
Starling raised an eyebrow. "Did you expect a medal?"
"You made me explain it four times."
"Three of them were inadequate."
"They were correct."
"They were answers to questions I did not ask."
Nathan disliked him intensely.
The feeling lasted perhaps twenty minutes.
Then Starling demonstrated something Nathan had never considered and Nathan changed his mind.
Physiology became one of the great torments of his education because every correct lesson gave Nathan another reason he should have been dead.
A human heart maintained circulation.
Nathan could stop his.
Human tissues depended upon oxygen.
Nathan discovered that breathing was optional.
Muscles fatigued.
Nathan could make fatigue disappear.
Damaged tissue passed through ordered stages of injury and repair.
Nathan's wounds simply ceased existing.
At first he tested himself cautiously.
He slowed his pulse while sitting alone.
Then stopped it for a minute.
Then ten.
Then thirty.
Nathan waited each time for dizziness, weakness, confusion, anything indicating that his body required the processes Starling described.
Nothing happened.
One evening he stopped his heart at nine.
He opened a physiology text and began reading.
At midnight his heart remained silent.
Nathan rested two fingers against his wrist and felt nothing.
No pulse.
No anxiety.
No increasing desperation for oxygen because, as another experiment, he had not breathed for most of those three hours either.
He looked down at the diagram of the human circulatory system on the page.
The image was correct.
That was what disturbed him.
Starling was not wrong.
Nathan was.
Or rather, whatever Nathan had become existed outside the assumptions upon which the diagram depended.
He allowed his heart to resume.
One beat.
Then another.
Perfect rhythm.
Nathan closed the book and slept for less than two hours before returning to the College.
That morning he waited until Starling had finished discussing circulation before asking, "If the heart stopped completely, how long could the brain continue functioning?"
Several nearby students looked toward him.
Starling slowly turned.
"Should I be concerned about your plans for this evening?"
Nathan smiled.
"Theoretically."
"Your theoretical questions increasingly resemble evidence."
Nathan's smile widened.
Starling went on, first humorously and then seriously, explaining what was known about loss of circulation and the rapid damage expected when the brain was deprived of blood.
Nathan wrote it all down.
He did not ask what three hours meant.
Zoology dismantled a different certainty.
Nathan entered expecting animals.
Minchin gave him things that challenged the usefulness of the word.
Edward Alfred Minchin had taken the zoology chair in 1899, and under him Nathan encountered sponges, protozoa, parasites, colonial organisms and forms of life so unlike vertebrates that Nathan initially found himself almost offended by their classification.
He stared at a sponge during an early practical.
Minchin noticed.
"Something troubling you, Drake?"
Nathan looked at the specimen.
"This is an animal."
"Yes."
"It doesn't appear to be making much effort."
Minchin smiled. "Neither do some students."
Nathan looked closer.
"There are no organs like ours."
"No."
"Yet the cells cooperate."
"Yes."
"And if they're separated?"
Minchin glanced toward him.
Nathan had already found the edge of the lesson.
"What do you think?"
Nathan became absorbed.
That happened repeatedly.
A single-celled organism performed within itself functions Nathan's human body distributed across tissues and organs. A parasite could incorporate another organism into its own life cycle so completely that the boundary between environment and body became conceptually uncomfortable. Colonial organisms made the word individual less certain than Nathan had ever imagined.
Minchin once remarked, after Nathan spent half an hour interrogating an unfamiliar structure, "You cannot look at anything living without asking it why it exists."
Nathan turned the specimen in his hand.
"It should have a reason."
"Evolution does not owe you elegance."
Nathan looked up.
"What does it owe?"
"Nothing."
Minchin took the specimen back.
"What survives is what survives. Do not confuse the result with an intention."
Nathan remembered that sentence too.
The zoology course ran for three terms, thirty weeks of lectures and practical work. Nathan attended all of it while continuing physiology, pathology, biology, chemistry where necessary and bacteriological reading long after his short formal course had ended.
By the middle of the year, Minchin finally asked the question Platt had asked months earlier.
"How many courses are you taking?"
Nathan looked up from his notes.
"Formally?"
Minchin closed his eyes.
"That answer already worries me."
"Zoology, pathology, physiology and biology."
"Four."
"And chemistry."
"Five."
"Bacteriology?"
"I finished the course."
Minchin looked relieved.
"I still study it."
The relief vanished.
"Five and a half, then."
Nathan laughed.
Minchin did not.
"You understand that keeping your name upon five registers is not the same as learning five sciences."
"I know."
"Do you?"
Nathan's smile disappeared.
Minchin recognised immediately that he had found the one accusation Nathan would not take lightly.
"Yes."
"How well are you doing in pathology?"
Nathan answered.
"Physiology?"
Nathan answered again.
Minchin stared at him.
Nathan leaned back slightly.
"If I fall behind, I'll stop."
"That is what Platt told me you said months ago."
"I haven't fallen behind."
"No."
Minchin's expression became thoughtful.
"That is what concerns everyone."
Nathan learned later that the professors had begun comparing him.
The discovery occurred when Starling mentioned something Nathan had only discussed with Martin.
Nathan looked up immediately.
"You've spoken to him."
Starling continued working.
"I have spoken to many people."
"About me."
Starling finally looked over.
"Yes."
"What did he say?"
"That you ask too many questions."
Nathan frowned.
"You say that."
"Yes."
"What does Minchin say?"
"That you ask too many questions."
"And Platt?"
"That you argue."
"I don't argue."
Starling stared at him.
Nathan realised what he had done.
Starling returned to his notes.
"Thank you for illustrating his point."
The conversations were not malicious.
The men were trying to determine whether Nathan was neglecting someone else's subject.
What disturbed them was that he wasn't.
Martin discovered that Nathan could move from bacteriology into pathology without treating them as separate worlds. Starling would raise a circulatory problem and see Nathan considering the pathological consequences before the question had been completed. Minchin once described a parasite's interaction with its host and watched Nathan's eyes shift with recognition.
"You are thinking about pathology."
Nathan nodded.
"And physiology."
"Yes."
Minchin waited.
Nathan hesitated.
"Possibly bacteriology."
Minchin rubbed his forehead.
"You are intolerable."
"So I'm told."
Pathology was the one subject Nathan deliberately slowed.
Sidney Martin had expected him to need approximately two years to reach the depth he claimed to want. By the end of the first, Martin informed him that he could satisfy the ordinary course expectations considerably earlier than anticipated.
Nathan refused.
They were standing over diseased tissue when Martin told him.
"You could complete the work this year."
Nathan kept looking through the preparation.
"No."
Martin thought he had misheard.
"No?"
Nathan straightened.
"I haven't finished."
"You will have completed the course requirements."
"That isn't what I said."
Martin looked at him.
Nathan gestured toward the specimen.
"I know what this is."
"Yes."
"I know what disease produced it."
"Yes."
"I understand what failed."
"Broadly."
Nathan nodded.
"But I don't understand everything that happened between healthy tissue and this."
Martin became quiet.
"No one does."
"I know."
Nathan met his eyes.
"That is why I want the second year."
"You are already carrying too much work."
"I am keeping up."
"You could have the qualification."
"I didn't come here for the qualification."
The answer came so quickly and with so little vanity that Martin stopped arguing.
Nathan stayed.
The second year of pathology changed the way he approached every other field.
Until then he had been extraordinarily good at acquiring answers.
Martin taught him to pursue mechanisms.
Healthy tissue did not become diseased tissue in an instant. Something occurred between the beginning and the specimen preserved at the end. There were stages. Interactions. Responses. A microscopic organism entered somewhere, multiplied somewhere, released something, destroyed something, triggered a reaction which itself could damage the host.
Nathan began thinking temporally.
Not merely what is this?
How did this become this?
His notebooks changed.
The questions he had written in 1899 became embarrassing.
Why does my heart remain unnecessary?
He crossed it out.
The question assumed the heart was secretly performing some unusual necessary function.
There was no evidence it was necessary at all.
Why do my wounds heal instantly?
Wrong again.
What Nathan did did not resemble ordinary healing closely enough to justify using the word.
He rewrote it.
What process replaces normal repair?
Another question changed from:
How can I become another animal?
to:
What information determines anatomical form, and where is that information retained?
The language became colder.
More useful.
By the second half of 1900 Martin noticed that Nathan was asking him fewer questions.
At first he thought the young man had finally exhausted himself.
Then he found Nathan alone after dark comparing two observations.
"What are you doing?"
Nathan did not look up.
"Checking."
"What?"
"Whether I was wrong."
Martin came closer.
"Were you?"
"Not yet."
"Then go home."
Nathan looked toward him.
"I haven't finished checking."
Martin sighed.
"You have become worse."
Nathan smiled.
Outside University College, the century continued without Nathan.
The South African War appeared daily in newspapers. Names of places thousands of miles from London became familiar over breakfast tables. Soldiers departed beneath waving handkerchiefs. Men argued in public houses over battles neither side had witnessed. Telegraph cables dragged distant events into the city with a speed earlier generations would have considered miraculous.
Nathan read enough to know what was happening.
Then returned to the laboratory.
At the beginning of 1901 Queen Victoria died.
Nathan stood among a crowd when the news passed through London and watched men remove their hats almost as one. Some women cried. Shop windows darkened. Bells sounded.
She had been Queen for longer than Nathan had been alive.
The thought should have made time feel enormous.
Instead Nathan found himself thinking of the mountain.
Victoria's entire reign was nothing beside the memories buried beneath it.
He did not say that to anyone.
He returned to his work.
By then the thirty-week zoology course had long since carried him through its full three terms. Completing the lectures had not caused Minchin to dismiss him; it merely meant Nathan no longer required the ordinary sequence. He stayed for more difficult comparative work, for specimens he had not encountered and questions for which identification alone was useless.
Minchin once placed an unknown structure in front of him.
Nathan examined it carefully.
"Identify it," Minchin said.
Nathan shook his head.
"I don't know."
"Good."
Nathan glanced up.
Minchin smiled.
"Tell me what you do know."
Nathan turned it.
Attachment points.
Probable mechanical forces.
Relationship between surfaces.
Likely movement.
He began inferring the animal.
Minchin stopped him.
"Evidence."
Nathan sighed.
"You've been speaking to Martin."
"Frequently."
Nathan returned to the specimen.
This time he separated observation from interpretation aloud. When certainty ended, he stopped.
Minchin nodded.
"Better."
"You used to complain I wasn't ambitious enough with an answer."
"I complained that you treated every bone as a criminal under interrogation."
Nathan smiled.
"Doesn't it owe us an answer?"
"No. It owes us precisely what it is. The rest is our responsibility."
Biology completed the pattern.
Nathan had entered it expecting foundations and found instead a language connecting everything else. Cell. Tissue. Development. Reproduction. Variation. Inheritance as the age understood it. Organisms not as static objects but as processes continuing through time.
The boundaries between his subjects began dissolving.
A bacterium encountered a host.
That was bacteriology.
The host changed.
Pathology.
Its organs failed.
Physiology.
A related species survived the same organism.
Zoology.
Why?
Biology.
Nathan began moving between them without noticing which department owned the question.
That was when his teachers stopped being surprised that he could keep up.
They became surprised by what he could do with all of it together.
Starling began mentioning pathological examples without explaining them first.
Martin occasionally asked Nathan what physiological effect he expected before telling him.
Minchin gave him organisms outside the course because Nathan no longer needed every observation placed into a familiar category.
The young man whom Platt had examined because nobody knew whether he possessed enough schooling for university had disappeared somewhere along the way.
In his place stood a man other students had begun quietly asking for help.
Nathan disliked that at first.
A younger student once approached him after physiology and asked whether he could explain something Starling had said.
Nathan looked behind him, assuming someone else was being addressed.
The boy hesitated.
"Mr. Drake?"
Nathan looked back.
"Yes?"
"Could you show me why the pressure changes here?"
Nathan stared at the notes.
For a moment he could remember being hungry at twelve.
Then he pulled out a chair.
"Sit."
He explained it.
Halfway through, the student nodded as though something had suddenly become obvious.
Nathan stopped.
"What?"
"I understand."
The words affected him more than praise from any professor had.
Nathan covered it by pointing back toward the paper.
"Then explain it to me."
The student did.
Nathan corrected him once.
Afterward he sat alone for several minutes, staring at the empty chair.
He had become someone capable of teaching.
That was new.
By the time two full years had passed since he first entered University College, the courses Nathan had once regarded as impossible ambitions had largely ceased being courses.
The short bacteriology programme had been completed back in 1899, though Martin joked that Nathan apparently considered this an administrative error because he had never actually left the subject. The three-term zoology course and its thirty weeks of formal lectures had been completed, followed by continued work with Minchin. Biology had reached its formal conclusion around the same period. Nathan's physiology had advanced until Starling increasingly gave him questions rather than lessons.
Pathology finally ended last because Nathan had chosen it that way.
Martin handed him the final work personally.
Nathan opened it.
There were no corrections.
He turned the page.
Nothing.
Another.
Nothing.
He looked up.
"You forgot to mark this."
"No."
Nathan frowned.
Martin held out his hand.
Nathan stared at it.
Then realised.
He stood and shook it.
Martin's expression softened.
"You could have done this a year ago."
"I know."
"You chose to stay."
"Yes."
"Was I worth another year?"
Nathan smiled. "Occasionally."
Martin laughed.
Nathan's smile faded into something more thoughtful.
"How much don't I know?"
Martin stared at him for a second.
Then smiled again.
"At last."
Nathan frowned.
"What?"
"You have finally asked the question that makes me confident you're ready to leave the course."
Nathan glanced around the pathology room.
"I don't want to leave."
"I didn't say leave pathology."
Martin leaned back against the bench.
"You know enough now that the questions which matter to you are no longer questions I can answer by pointing toward a page."
Nathan remained quiet.
Martin continued.
"You can recognise disease. Follow its progress. Compare cause and consequence. You understand enough physiology to know what the changes mean to the organism, enough bacteriology to think about infectious causes, enough biology to stop treating tissue as though it exists independently of everything surrounding it."
Nathan listened.
"What comes next?"
Martin smiled faintly.
"You discover where the books are wrong."
That stayed with him.
Platt summoned Nathan not long afterward.
Penrose was waiting in the office when he arrived.
Nathan stopped in the doorway.
He looked at Penrose.
Then Platt.
"What happened?"
Penrose laughed.
"Nothing happened."
"You're both here."
"I visit people without catastrophe occurring."
Nathan raised an eyebrow.
Penrose reconsidered.
"Occasionally."
Platt pointed toward the chair.
"Sit."
Nathan sat suspiciously.
Several reports lay on the desk.
He recognised Starling's handwriting, Martin's, Minchin's.
Nathan looked at Platt.
"What did I do?"
Platt removed his spectacles.
"Do you remember the first day you came into this room?"
"Yes."
"You attempted to answer questions incorrectly because you believed your actual knowledge would appear suspicious."
Nathan looked away.
Penrose's eyebrows rose.
"You did?"
Nathan sighed.
"Not now."
Penrose began smiling.
"I wish I had known that."
"You didn't need to."
Platt cut through them. "At the time I was uncertain whether you possessed enough coherent education to become a university student."
Nathan's humour disappeared.
He remembered.
Platt continued.
"I expected your preparation to take the better part of a year. It took months. You then proposed to study several disciplines simultaneously despite being advised repeatedly that doing so was foolish."
Penrose leaned toward Nathan.
"You ignored good advice?"
Nathan looked at him.
"Apparently."
"Remarkable."
Platt continued before the conversation escaped him entirely. "You finished the bacteriology course almost immediately and simply continued studying bacteriology afterward. You completed three terms of zoology and stayed there as well. Your biology work was completed. Starling informs me that in physiology he is now increasingly forced to give you research literature if he wants you to remain occupied."
Nathan looked toward the report.
"And Martin?"
Platt touched the final paper.
"Martin says you could have finished pathology in one year."
Nathan nodded.
"I know."
"And instead remained for two because you felt completing the requirement was insufficient."
"Yes."
Penrose stared at him.
"You voluntarily remained in examinations you could have finished?"
"It wasn't just examinations."
"That does not improve the insanity."
Nathan smiled.
Platt leaned back.
"Do you know what mastery means, Drake?"
Nathan considered the word.
"Knowing the subject."
"No."
Nathan frowned.
Platt looked toward the reports.
"If Martin announced tomorrow that he had mastered all pathology, I would recommend immediate medical supervision. If Minchin said nothing remained unknown to him in zoology, he would prove himself a fool. Mastery does not mean reaching the end of a science."
Nathan listened more carefully.
"It means reaching the point where you can work within it without another man carrying you."
Something inside Nathan went still.
Platt touched Martin's report.
"You are there in pathology."
Then Minchin's.
"In zoology."
Another.
"In bacteriology, you surpassed the formal course almost immediately."
Starling's came last.
"And Starling believes you are approaching the same point in physiology."
Nathan looked down at his hands.
Two years ago those hands had rested on the same desk while he waited for Platt to decide whether he was educated enough to belong in the building.
Penrose's voice came quietly from beside the window.
"You asked us for this instead of the money."
Nathan looked toward him.
Penrose smiled.
"I thought at the time you were either unusually clever or unusually foolish."
"Which?"
"I still haven't decided."
Nathan laughed softly.
Then Platt asked, "What do you intend to do now?"
Nathan's answer came more quickly than he expected.
"Research."
Platt nodded as though he had been waiting for it.
"On what?"
Nathan looked at the reports spread across the desk.
Infectious organisms.
Living systems.
Disease.
Variation.
Structure.
Every separate road had somehow curved back toward the same problem.
"Change."
Platt's brow furrowed.
Nathan clarified.
"How an organism changes another organism. How disease alters tissue. How bodies preserve their form. Why one animal survives what kills another."
"And you believe these questions are connected?"
"Yes."
"By what?"
Nathan was silent.
That was the part he could not tell him.
By a sea beneath Africa which had taken twelve men apart and built something new from them.
Instead he said, "I don't know yet."
Platt smiled.
"Better."
Nathan looked at him.
"Better than what?"
"Pretending you do."
That evening Nathan returned to his rooms and opened the notebook he had begun during his first weeks in London.
He had not looked at the earliest pages for some time.
Physiology.
Anatomy.
Zoology.
Bacteriology.
He turned the page.
Why does the heart remain unnecessary?
Nathan crossed it out.
Not because he had an answer.
Because it was the wrong question.
Where are memories stored?
Another line.
Insufficient.
What determines form?
He left that.
Can one organism contain the structures of another without rejection?
Nathan stared at it for a while.
Better.
Then came the questions written after he encountered the work of Ivanovsky and Beijerinck.
Can a disease think?
Nathan rested the end of the pen against his lip.
Then:
Can it remember?
Those questions had once terrified him.
They seemed almost naive now.
Nathan turned to a clean page.
He wrote:
There is no evidence that a separate infectious organism exists within me.
The words looked strange.
He continued.
No host response has been observed. No boundary exists between altered and unaltered tissue. Every part examined behaves as part of the same system.
Nathan paused.
Then:
The distinction between Nathan Drake and the organism beneath the mountain may therefore be artificial.
He watched the ink dry.
For two years he had imagined himself infected.
That idea had been comforting, though he had not realised it.
Infection implied two things.
Nathan.
And something else.
Host and pathogen.
Man and disease.
If the distinction did not exist—
then the thing that had walked from the mountain was not carrying the red sea inside him.
It was the red sea.
And Nathan Drake.
Both statements could be true because perhaps they had become the same statement.
Nathan turned the page.
At the top he wrote:
Research.
His handwriting had changed over the years, becoming cleaner, smaller, less impulsive.
Below it:
Determine the mechanism by which biological form is acquired, retained and reproduced.
Then:
Determine whether this mechanism is analogous to infection, inheritance, assimilation, or an as-yet undescribed process.
Animals would come first.
Not because Nathan had developed a moral objection to human experimentation.
He had not.
Animals were simply easier.
Rats multiplied quickly. Rabbits were inexpensive. Dogs could provide larger comparative systems. Dead tissue could answer questions living organisms could not, and living organisms could answer questions dead tissue could not.
Science required the correct tool for the question.
Nathan wrote:
Begin with animal tissue and live animal subjects. Establish repeatable baseline observations before introducing human material.
The next sentence came without hesitation.
Human tissue will eventually be necessary.
He read it.
Nothing inside him recoiled.
Perhaps it should have.
Nathan considered that possibility seriously.
Martin would object.
Platt certainly would.
Penrose would look at Nathan differently if he ever read these pages.
But Nathan did not confuse their morality with his own.
He had killed before the mountain.
He had killed after it.
He had consumed men. Carried their memories. Worn their faces. Walked out of a forest in the body of a man whose neighbours had watched him vanish into the trees.
University College had made him educated.
It had not made him gentle.
Nathan was not cruel for pleasure. That distinction mattered to him. Suffering without purpose seemed wasteful, and now he possessed scientific reasons to avoid it as well. Pain altered pulse. Fear changed breathing. Stress affected physiology. Injury introduced variables. A terrified subject was no longer the same subject observed at rest.
Unnecessary cruelty was not merely distasteful.
It was poor experimental design.
Nathan wrote:
Avoid unnecessary trauma unless trauma itself is the variable under examination.
Then, after a moment:
Living human subjects may be required when animal models are insufficient.
He left the sentence where it was.
There were easier sources first.
Hospitals discarded tissue.
Morgues possessed corpses.
Blood could be taken.
Surgical material could be obtained.
Nathan knew enough now to understand that a dead human body could answer hundreds of questions before a living one ever became necessary.
But if that necessity came, Nathan would not pretend the line existed simply because respectable men would prefer it.
The next question mattered more.
Does assimilation require the death of the source organism?
Nathan stopped writing.
Everything he consciously remembered acquiring had died.
The men in the mountain.
The wolf.
Other animals afterward.
But death might have been a consequence rather than a requirement.
He looked at his hand.
The skin rippled almost imperceptibly.
His fingers broadened.
The knuckles changed.
A scar appeared.
Ward's.
Nathan ran his thumb across it.
The tissue possessed the slight raised roughness of an old injury. It was not an image painted onto skin. Nathan could cut it open and find the altered structure beneath.
Yet Nathan had never suffered the wound.
Ward had.
Ward was dead.
The injury survived.
Nathan made the hand his own again.
What had he actually taken from Ward?
Not simply matter.
The matter was gone.
Nathan had replaced it countless times since.
But somewhere inside him existed enough information to reconstruct Ward's hand down to an old scar.
Information.
The term was inadequate, but Nathan had no better one.
Biology at the beginning of the twentieth century did not yet possess the language he needed.
It knew inheritance existed.
It knew offspring resembled parents.
Mendel's work, largely ignored for decades, was only now being rediscovered and dragged back into scientific attention around the turn of the century. Something transmitted form across generations.
Nathan wondered whether the thing beneath the mountain had discovered the same principle millions of years ago by another route entirely.
He wrote:
What is acquired from the source?
Then:
Is complete consumption required for acquisition?
Another line.
If partial acquisition is possible, can the source survive?
Nathan sat back.
A living subject who survived contact would be far more useful than one consumed immediately.
Repeated observations.
Changes over time.
Comparison before and after exposure.
The same organism serving as its own control.
His mind began constructing experiments before he consciously invited it.
Nathan wrote another note.
A surviving subject permits longitudinal observation impossible after complete assimilation.
The clinical language made the thought sound almost respectable.
Nathan knew better.
He did not care.
He turned several pages and began listing variables.
Contact duration.
Amount of transferred biomass.
Species.
Age.
Health.
Temperature.
Existing disease.
Injury.
Whether Nathan deliberately attempted to acquire information or merely exposed tissue to himself.
That last one stopped him.
Intent.
He underlined it.
Was assimilation automatic?
Or had the red sea responded to will?
Nathan remembered the wolf.
The sudden transition from animal outside him to animal remembered.
He remembered changing his face after leaving the mountain.
Nobody had taught him how.
He had wanted to be someone else and flesh had obeyed.
The biological system Nathan inhabited might respond directly to conscious intention.
No known animal worked that way.
At least not to this degree.
He wrote:
Determine relationship between conscious intent and morphological change.
Then:
Can involuntary biological responses be separated from deliberate ones?
His pages filled.
For the first time since Africa the questions no longer felt like panic.
They looked like work.
Outside, London was entering the twentieth century beneath gaslight and smoke.
Science was changing around him almost as quickly as Nathan could follow it. Invisible bacteria had become specific causes of disease. Filterable agents had opened another world beneath them. Mendel's forgotten experiments were being rediscovered. Physiology was beginning to treat the body less as a collection of organs and more as a system of chemical and physical relationships.
Nathan intended to watch all of it.
Perhaps participate.
There was another fact he had begun recording separately.
Two years had passed.
Nathan had not aged.
Not naturally.
He had altered himself enough to prevent anyone noticing. A little heaviness beneath the eyes during examinations. Slight changes in weight. Hair cut differently. Once he allowed the faint beginnings of a line beside his mouth because Harbury had joked that university seemed determined to age him before his time.
The line had not appeared on its own.
Nothing did.
Beneath every deliberate adjustment remained the same body that had walked from the African mountain.
Twenty-five.
Nathan had not yet written immortal.
That would have been precisely the sort of conclusion Martin had taught him not to make.
Two years were insufficient evidence.
Ten years might be interesting.
Twenty would be difficult to explain.
Fifty—
Nathan stopped.
The thought no longer seemed ridiculous.
That frightened him less than it should have.
He closed the notebook and sat in silence for a while.
University College had failed to give him the answer he originally wanted.
Nathan had arrived asking, silently, What happened to me?
There had been no book containing the explanation.
No lecturer had recognised the thing sitting in his classroom.
No microscope had revealed an invader.
No physiological principle had explained him.
No pathology described him.
No known animal possessed his capacities.
Even the emerging idea of a virus seemed too narrow.
And yet those two years had not been a failure.
Platt had taught Nathan how to recognise the difference between knowledge and confidence.
Martin had taught him to say I don't know without treating the words as defeat.
Starling had taught him that a correct observation without mechanism was only the beginning.
Minchin had taught him that classification did not create understanding.
Every one of them had given Nathan something more useful than an answer.
Method.
Nathan opened the notebook once more.
At the bottom of the final page he added one sentence.
Do not assume human biology defines the limits of biology.
He stared at it for a moment.
Then closed the book.
The lamp went out.
Darkness filled the room, but Nathan's eyes adjusted almost immediately.
The pulse in his chest continued.
He let it.
For now.
Two years earlier Nathan Drake had entered University College hoping the men inside would tell him what he was.
By 1901, he had mastered enough bacteriology, physiology, pathology, zoology and biology to understand why they could not.
Human science simply had not reached him yet.
So Nathan would help it catch up..
..
Nathan knew something had changed before Platt said a word.
It was in the way other people had begun entering rooms that belonged to him.
Two years earlier, Nathan had waited outside offices. He had carried letters of introduction and sat where he was told to sit while men decided whether he possessed enough education to be worth another man's time. Even after University College had accepted him, there had remained an invisible distinction between Nathan and the people who worked there. Professors had rooms. Demonstrators had benches and keys. Lecturers came and went through doors Nathan entered only after knocking. Nathan had been a student, however peculiar a student he eventually became, and students occupied the College at somebody else's permission.
Now Platt knocked on Nathan's door.
Nathan looked up from the microscope.
For several seconds he did not answer.
The room was not truly his. It was one of the smaller working rooms he had been allowed to use with increasing regularity as his studies moved beyond scheduled practicals, but possession was a matter of habit as much as paperwork. Nathan had spent enough evenings there that books had accumulated in uneven towers along one wall. Three notebooks lay open beside the microscope. A tray beneath the window held several prepared sections Martin had allowed him to keep for comparison, and Minchin had threatened more than once to have Nathan charged rent for the shelf upon which zoological specimens continued appearing.
Another knock came.
"Drake?"
Nathan relaxed.
"Come in."
Platt entered carrying a leather folder thick enough to make Nathan immediately suspicious.
Nathan glanced toward it and then back through the microscope.
"No."
Platt stopped just inside the door. "I have not said anything."
"You brought paperwork."
"I often carry paperwork."
"You don't bring it to me unless you want something."
Platt closed the door behind himself. "You have developed an unfortunate understanding of academic administration."
Nathan adjusted the focus slightly. "Two years of exposure."
"And somehow survived."
"Barely."
Platt approached the bench and looked over Nathan's shoulder, though whatever lay beneath the microscope clearly meant nothing to him. "Martin?"
Nathan nodded.
"Pathological section?"
"Liver."
"Human?"
"Rabbit."
Platt seemed relieved enough by that distinction to interest Nathan.
"Something wrong with rabbits?"
"No."
"You looked pleased."
"I looked nothing of the sort."
Nathan finally lifted his head from the eyepiece and regarded him. "You've spent two years telling me my face gives away more than I think it does."
"And you have spent two years refusing to improve."
Nathan smiled faintly.
Platt set the folder on the clear corner of the bench.
The sound it made killed the humour.
Nathan looked down.
There were several separate papers inside. He could see different handwriting before Platt opened anything. One large, impatient hand Nathan recognised immediately as Starling's. Martin's was more controlled. Minchin's occupied another sheet. There were additional documents beneath them, typed and formal, bearing College headings rather than personal handwriting.
Nathan's smile disappeared.
"What happened?"
"Nothing happened."
"That is precisely what Penrose said the last time everyone was conspiring."
"No one is conspiring."
"Then why do you have letters from three of my professors?"
Platt pulled out the chair opposite the bench and sat.
"Because they wrote them."
Nathan stared at him.
Platt stared back.
After a moment Nathan said, "I had gathered that."
"One of the more remarkable features of your education is that increased learning has done absolutely nothing for your patience."
Nathan closed the microscope slide beneath its cover and pushed the instrument carefully away.
"All right. What are they?"
Platt rested both hands on the folder but did not immediately answer.
The pause made Nathan uneasy.
Not frightened. Nathan had become increasingly difficult to frighten in any ordinary sense of the word. But something about formal paper still reached an old part of him. A warrant was paper. A prison register was paper. A record containing his old face and old name still existed somewhere because somebody had once considered his life important enough to write down.
University College had gradually given paper another meaning.
Marks.
Recommendations.
Reports.
Proof that Nathan Drake could be valuable rather than merely dangerous.
Platt withdrew the first letter.
"Martin."
Nathan recognised the handwriting.
"He believes your pathological work has reached the point where keeping you merely as a student would be somewhat artificial."
Nathan's eyebrows drew together. "He said I was finished."
"He said your course was finished."
"That sounds suspiciously similar."
"To you, perhaps."
Platt placed the letter down and drew out the second.
"Minchin is considerably less restrained."
Nathan looked at it.
"What did he say?"
"You may read it afterward."
"That means something embarrassing."
"It means I prefer completing a sentence occasionally."
Nathan leaned back.
Platt continued, "Minchin states that you have completed the formal zoological work expected of you, that your comparative work is substantially beyond the level at which he would ordinarily treat a student, and that he has already been using you informally to assist less experienced men in practical work."
Nathan's expression changed.
"I helped twice."
"Apparently Minchin counts six occasions."
Nathan frowned.
Platt almost smiled.
"There is also Starling."
Nathan's eyes went toward the largest handwriting.
"That one is probably an insult."
"Several, actually."
Nathan looked unsurprised.
Platt picked up the paper.
"He describes you as impatient, argumentative, overly willing to extend experiments beyond the original question and incapable of leaving a difficult subject alone once it has acquired your attention."
"That sounds like him."
"He then recommends you without reservation."
Nathan stopped.
Platt lowered the letter.
For once Nathan had nothing ready.
The rain outside had become heavier without him noticing it. Water whispered against the window while distant movement continued through the College beyond the room—doors opening, shoes against stone, a laugh somewhere along the corridor. Nathan could hear all of it if he wanted.
Instead he heard the last sentence again.
Recommends you.
"For what?"
Platt opened the folder fully.
The formal papers underneath were revealed.
"A demonstratorship."
Nathan did not move.
Platt watched him.
Nathan finally asked, "Here?"
"No, Drake. At the Zoological Gardens. They need someone to explain the giraffes."
Nathan gave him a flat look.
"Yes," Platt said. "Here."
Nathan reached for the document but stopped before touching it.
"What department?"
"That remains part of the discussion."
Nathan looked up.
Platt settled more comfortably into the chair. "Your habit of refusing to belong neatly to a single discipline has created a certain inconvenience. Martin would take you in pathology. Minchin believes you would be useful in practical zoology and general biology. Starling has expressed interest in having you continue work within physiology, although his idea of expressing interest is apparently to write half a page explaining the burden you would impose upon him before spending another page explaining why somebody ought to appoint you."
Nathan smiled despite himself.
"He likes me."
"In whatever sense Starling permits himself to like anybody who interrupts him."
Nathan picked up the papers.
The word caught his eye.
Demonstrator.
He knew what it meant by then. Demonstrators lived somewhere between student and lecturer in the working anatomy of the College. They prepared practical material, supervised students at benches, demonstrated methods and structures, assisted professors and helped keep laboratories functioning. They were staff, though junior staff, and a good demonstrator could acquire something almost as valuable as salary.
Access.
Nathan turned the first page.
"How much teaching?"
"Demonstrating rather than lecturing, initially. Practical classes. Preparation. Helping students who have managed to hear an entire explanation without understanding it."
"So most of them."
Platt sighed.
"You will discover very quickly that being clever does not make contempt attractive."
"I wasn't being contemptuous."
"You sounded very much like Starling just then."
Nathan looked genuinely alarmed.
"Take that back."
"No."
Platt allowed him to read.
There was a modest salary attached to the proposed appointment. Not large, but respectable for a young academic position and almost irrelevant compared with what Nathan had already begun considering.
The salary was not the important part.
Nor was the title.
Nathan looked across the recommendations again.
Martin.
Minchin.
Starling.
Two years ago none of those men had known he existed.
Now three departments were putting their names beneath arguments for keeping him.
Something subtle moved inside Nathan.
He had become useful to them.
Not tolerated.
Not sponsored because Patterson had pulled him out of Africa wrapped in a heroic story.
Useful.
That distinction was more important than praise.
Useful men were given keys.
Useful men were allowed into laboratories when students were not.
Useful men were trusted with materials.
Useful men could ask for things.
Nathan lowered the papers.
"What happens if I accept?"
Platt had clearly expected excitement, gratitude, perhaps an immediate yes.
Nathan's question made him pause.
"You become a member of the College staff."
"I understand that."
"You are paid."
"I saw."
"You perform whichever demonstrator duties are settled upon. Practical classes. Preparations. Assisting the relevant professor. Some supervision of students. You would continue your own reading, naturally."
Nathan's gaze remained fixed on him.
Platt recognised the look.
"What?"
Nathan did not answer immediately.
He chose the wording carefully.
"Would I be permitted to conduct research of my own?"
That changed something.
Not suspicion.
Attention.
Platt leaned back slightly.
"There it is."
Nathan frowned. "There what is?"
"The reason you have not asked once about the salary."
Nathan looked back at the document.
"The salary is fine."
"You have not even reached the figure on the second page."
"I saw it upside down."
Platt stared at him.
Nathan realised.
"That isn't normal, is it?"
"No."
Nathan put the document down.
Platt's amusement remained for another moment before fading into thoughtfulness.
"What do you mean by private research?"
Nathan had anticipated the question.
"My own work."
"That is not quite the same word."
"Independent, then."
"Better."
Nathan folded his hands loosely together.
"If I accepted a staff appointment, performed the demonstrations, prepared whatever needs preparing, taught the students and did what the department required of me, would the rest of my laboratory time belong entirely to whoever I worked under?"
"No."
Nathan's eyes sharpened.
Platt continued, "A demonstrator is not an indentured laboratory servant, despite what some professors occasionally appear to believe."
Nathan smiled faintly.
"You would certainly be expected to assist the department's work. If you were attached to Starling, for example, you would not be free to announce that circulation no longer interested you and spend six months breeding moths in a cupboard."
"I don't want to breed moths."
"I am relieved."
"But research of my own would be allowed."
"Yes."
Nathan did not respond.
Platt watched the calculation occurring behind his face and apparently found it entertaining.
"You are already doing it."
"Reading isn't research."
"No. But Martin tells me you have begun repeating observations without being instructed to do so, and Minchin tells me you have somehow accumulated more comparative notes than several men officially engaged in comparative work. Nobody believes a staff position will suddenly make you less curious."
Nathan glanced down at the folder.
"And materials?"
Platt's expression became more serious.
"What about them?"
"If I needed them."
"What sort?"
Nathan shrugged lightly. "Glassware. Stains. Cultures where appropriate. Animal tissue. Specimens. Access to the usual equipment. Whatever the work required."
He kept his tone casual.
Platt gave him the answer Nathan had hoped for and not quite believed he would hear.
"Within reason, yes."
Nathan was very still.
"As staff?"
"As staff."
"The College pays?"
"The department possesses budgets, Drake, not Aladdin's lamp."
Nathan almost laughed.
Platt tapped the folder.
"If your research falls properly within the work of the department, ordinary materials and laboratory requirements can be provided. You make the case to the professor responsible. If you require something unusual or expensive, you justify the expense and it goes through the appropriate channels. If your work begins producing results, securing further support becomes considerably easier."
Nathan listened without interrupting.
"And laboratory access?"
"Yes."
"After teaching hours?"
"Within the rules of whichever laboratory employs you."
"At night?"
Platt's eyes narrowed faintly.
"You are already here at night."
Nathan looked around.
"That is not an answer."
"Yes, provided your professor permits it and you do not burn down the College."
Nathan nodded slowly.
Platt now looked openly suspicious, but only in the ordinary human way one became suspicious of a young researcher who had discovered somebody else might pay for his experiments.
"What exactly are you planning?"
Nathan smiled.
"Nothing yet."
"That is a lie."
Nathan's smile widened slightly.
Platt sighed.
"I should amend my earlier judgement. You have become better at lying. Merely not good enough."
Nathan looked toward the rain.
He did have plans.
Pages of them.
Not experiments he could begin tomorrow. Martin had taught him better than that. Nathan's notebooks contained too many unanswered preliminary questions. He needed proper baseline work, animal comparisons, a deeper understanding of tissue survival outside the organism, more microbiology, more histological technique, more chemistry.
But the obstacle Nathan had expected to dominate the next stage of his life had abruptly become smaller.
He had expected to need money.
A private laboratory.
Equipment.
Rooms isolated enough that questions would not be asked.
He had imagined purchasing apparatus piecemeal and conducting crude experiments somewhere outside London, perhaps under another name.
Instead University College was offering him a key.
Nathan looked back at Platt.
"If I produced something that was mine?"
Platt's brow furrowed.
"Academically?"
"Yes."
"You mean if the research were independent of the professor's own project."
"Yes."
"Then you publish it under your own name."
Nathan said nothing.
The simplicity of the answer almost bothered him.
Platt continued, "You would be expected to discuss work of consequence with the head of the department. You do not simply occupy a College laboratory, use College materials and then pretend the institution does not exist. But nobody appoints a promising man to staff merely so that he can spend the rest of his career washing glassware for better-known men."
Nathan looked down at Starling's recommendation.
"Starling might."
"Starling would make you wash glassware and conduct three experiments at the same time."
"That sounds more likely."
Platt smiled.
Nathan turned another page.
"So if I do the demonstrations, assist with practical teaching, keep the laboratory work expected of me in order, then I may pursue my own research using College facilities."
"Yes."
"And reasonable material costs are covered."
"Yes."
"As long as the work can be justified."
"Academically, yes."
Nathan was quiet.
Platt regarded him for a moment.
"Why do I feel I have just helped negotiate against the College?"
Nathan laughed softly.
"You came with the offer."
"Yes. I am beginning to appreciate the tactical error."
Nathan placed the papers neatly together.
Something had been forming inside him since Platt first said demonstratorship.
It was not gratitude.
Nathan was grateful, certainly. He was not so far removed from humanity that kindness had become meaningless to him. Penrose had opened the first door. Platt had tested him rather than dismissing him. Martin, Starling and Minchin had taught him seriously enough to criticise him. Those things mattered.
But there was another feeling beneath gratitude.
Opportunity.
University College did not know what it possessed.
That thought was not arrogance.
Nathan had spent two years learning enough to state it as an observation.
They believed they had an unusually capable young scholar who had come from poverty, survived Africa, arrived with an irregular education and then consumed scientific instruction at an extraordinary pace. They had watched him master practical work, move between departments and connect subjects most students kept separate.
They considered that valuable.
They had no idea how valuable Nathan found them.
The College possessed laboratories.
Microscopes.
Animals.
Specimens.
Chemical reagents.
Preserved tissues.
Men whose entire careers consisted of knowing things Nathan still needed to know.
More importantly, it possessed legitimacy.
A private citizen purchasing unusual quantities of biological material might eventually invite questions.
A university demonstrator ordering stains, slides, culture media or experimental animals was doing his job.
Nathan felt the implications unfold one by one.
Platt mistook his silence.
"You need not decide today."
Nathan looked up.
"I've decided."
Platt paused.
"That quickly?"
Nathan picked up the recommendation letters again.
"I wanted to know what I would actually be accepting."
"And now you do."
"Enough of it."
"That phrase concerns me."
Nathan ignored that.
"When would I begin?"
Platt laughed once in disbelief.
"We have not even decided which department formally gets you."
"Who wants me?"
"Martin."
"Who else?"
"Minchin."
"Starling?"
"Starling claims he has no interest in competing for staff."
Nathan waited.
Platt sighed.
"He then wrote the longest recommendation."
Nathan smiled.
"Physiology?"
"Possibly. There is discussion of an appointment broad enough to allow practical work across the biological teaching rather than chaining you exclusively to one room. Your unusual collection of completed courses has made the ordinary arrangement less convenient."
Nathan's eyes sharpened again.
"Across departments?"
"Do not become greedy."
"I was asking."
"You were salivating."
Nathan laughed.
Platt gathered the loose letters but left the formal offer in front of him.
"Whatever final arrangement is made, you will have a principal department. You cannot belong equally to half the College merely because you have annoyed half its professors."
Nathan leaned back.
"I could try."
"That is precisely what everyone fears."
For a while neither spoke.
Rain moved steadily against the window.
Nathan's gaze drifted toward the microscope.
Rabbit liver waited beneath the lens.
One small piece of one animal.
Human beings had built entire sciences by cutting the living world into pieces small enough to understand.
Nathan wondered what they would think if they knew the thing sitting beside their microscope could reproduce the whole animal from a piece of information no instrument they possessed could see.
He wondered whether Beijerinck's invisible agent would prove to contain some clue.
Whether Mendel's rediscovered laws would.
Whether there was something inside cells men had not yet identified that carried form from parent to child.
Whether Nathan possessed the same machinery or had become something that merely imitated its results.
And now the College was willing to pay for him to investigate.
Not that question.
They could never know the real question.
But perhaps they did not need to.
Nathan looked toward Platt again.
"One more thing."
Platt closed his eyes briefly.
"Of course."
"If I begin a line of research and it leads somewhere unexpected, do I require permission every time the question changes?"
"No."
Nathan waited.
Platt understood what he meant.
"Research is not a railway, Drake. No one expects you to know the destination before you begin. Provided the work remains within the lawful and practical scope of the laboratory, you follow the evidence. If you begin requiring unusual resources, dangerous material, substantial expense or work outside the department's competence, then naturally you speak to the professor."
Nathan nodded.
Lawful.
That word settled somewhere apart from the others.
Platt continued, unaware of its importance. "You will keep records. You will not conceal accidents. You will treat College equipment as though someone besides you expects to use it afterward. And if you discover something worthwhile, you will not wait six months to mention it because you want to be certain."
Nathan smiled faintly.
"That last one sounds like Martin."
"It is Martin."
"He complained."
"At length."
Nathan looked again at the offer.
Staff.
The word appeared far less significant on paper than it did in his mind.
Two years ago he had arrived at Tilbury carrying borrowed clothes, an invented childhood and a face his own family would never recognise.
He had asked the Railway for education because knowledge seemed more useful than money.
He had been right.
Knowledge had made him valuable.
Value had produced trust.
Trust had produced access.
And access—
Nathan's thumb moved slowly over the edge of the paper.
Access might eventually produce answers.
"I'll take it."
Platt's expression softened.
Nathan noticed, and immediately regretted that he had because some part of him recognised pride there.
Not ownership.
Not the satisfaction of a man whose charity had succeeded.
Pride.
The sort a teacher might feel when a student ceased requiring him in the same way.
Platt extended his hand across the bench.
Nathan looked at it.
For one fleeting moment he remembered Martin doing the same at the end of pathology.
Then Penrose at Tilbury.
Patterson in Africa.
Human beings had an extraordinary habit of offering hands to things they did not understand.
Nathan took it.
Platt shook once, firmly.
"Congratulations, Mr. Drake."
Nathan's mouth moved into a small smile.
"Thank you."
"You will regret agreeing once you meet your first practical class."
"I survived Tsavo."
"Lions are predictable."
Nathan laughed.
Platt released his hand and began putting the recommendations back into the folder. "Keep those."
Nathan frowned.
"The letters?"
"They concern you."
Nathan touched Starling's page.
"He'll hate that."
"Which is another reason to keep it."
Nathan smiled and gathered them carefully.
Platt reached the door before Nathan spoke again.
"Professor."
Platt looked back.
Nathan had lowered his eyes to the offer.
"If the research is successful... if I produce work worth continuing... how far would the College support it?"
Platt studied him for several seconds before answering.
"As far as you can persuade serious men that it deserves to go."
Nathan looked up.
That answer was better than a number.
Platt opened the door.
"Perform your duties. Do good work. Produce evidence. If you need material, ask for it. If you need apparatus, justify it. If your results warrant further expense, people become remarkably willing to find money."
He smiled slightly.
"Universities are much more tolerant of obsession when obsession produces publishable results."
Nathan laughed.
Platt left.
The door closed.
Nathan remained alone.
For perhaps a minute he did nothing.
Then he locked the door.
Not because anybody was coming.
Habit.
He opened the drawer beneath the bench and removed the notebook Platt had never seen.
It fell open near the back almost automatically.
Research.
Pages of questions followed.
Nathan read through them until he reached the section he had begun concerning assimilation.
Does assimilation require death of the source organism?
What information is acquired?
Can biological form be acquired without complete consumption?
Can the source survive partial assimilation?
What determines retention?
Nathan added a new line.
University College laboratory access secured.
He stopped.
The wording seemed almost absurdly mundane.
He added beneath it:
Position will provide legitimate access to equipment, specimens, experimental animals and ordinary research materials. Independent work permissible provided duties are fulfilled and expenditure remains justifiable.
Nathan stared at the sentence.
Then another thought occurred.
He wrote more slowly.
The true subject of research need not be disclosed until necessary.
That was the important distinction Platt had not made.
The College would expect records of experiments conducted under its name. Nathan understood that. It would expect to know what materials he purchased, what animals he used, what results he intended to publish.
But experiments had layers.
A rabbit could be used for a perfectly respectable study of tissue response.
Nobody needed to know what Nathan did with one drop of his own blood before the animal was dissected.
A specimen could be examined for pathological change.
Nobody needed to know why Nathan had chosen that particular change.
A series of comparative observations could generate a publishable paper while answering an entirely different question for Nathan.
He would not begin recklessly.
He had learned too much for that.
Martin's voice remained inside his habits now, if not inside his memories.
Evidence first.
Nathan looked through the window.
The rain was easing.
Students moved across the courtyard below, coats drawn tight, books beneath arms. Somewhere among them were men Nathan had helped during practical lessons. Soon he would stand at the front of those practicals not as an older student who happened to understand the material but as part of the College itself.
The thought should have seemed ridiculous.
Instead it felt inevitable.
Nathan closed the notebook and returned it to the drawer.
He unlocked the door.
Then he sat once more before the microscope and lowered his eye to the rabbit tissue.
The liver appeared beneath the lens.
Cells.
Structures.
An architecture of life assembled from units too small for the naked eye to distinguish.
Nathan adjusted the focus.
For two years he had paid University College to teach him how to look.
Now University College intended to pay Nathan to keep looking.
Neither side yet understood how far he intended to go.
CHAPTER COMPLETE.
let me know what you guys think, the next few chapters will eb taking place of the course over a decade or so
