The water hit me before I was ready for anything.
Not a splash. A sustained, deliberate pour — the kind that doesn't stop when you flinch, that finds the gap between collar and neck and keeps going until it has soaked through every layer down to the skin. I came up from whatever I'd been in — sleep, unconsciousness, something without a name — gasping, the cold contracting my lungs before my eyes had even fully opened.
For a moment I was nothing. Just wet and cold and breathing too fast.
Then, gradually, I was a room.
Small. Metal walls, seamed at the joints, the kind of construction that existed in exactly one context. A table in front of me, scarred wood, the edges worn down by years of elbows and fists and the particular friction of people who did not want to be sitting where they were sitting. One arcane lamp above it, running low — a bare thermal coil behind smoked glass, giving off just enough orange light to see by and not enough to feel warm. No windows. The door, wherever it was, had to be behind me, because there was nothing in front of me except the table and the two men standing on the other side of it and the flat metal wall beyond them.
I tried to stand up.
My wrists caught. Iron, hinged, locked to the back of the chair. I felt the pull of them before I'd fully registered what they were, and the jerk of stopping short — arms wrenched back, chair scraping stone — was humiliating in a way that sat separately from everything else, a small precise indignity in a situation that was apparently full of them.
I sat back. I breathed. I looked at my hands, which I could not see, and then I looked at the two men, which I could.
Imperial Police. The uniforms said it before anything else could — dark wool, high collar, the silver gear-and-chain insignia of the Dominion's enforcement apparatus. The older one was broad through the chest and shoulders, mid-forties, with a face that had settled long ago into an expression of professional patience. He was standing with his hands clasped behind his back, watching me with the particular quality of attention that had no urgency in it. Not waiting for me to do something. Just — watching. Processing.
The younger one was to his left and slightly behind, a folder tucked under one arm. Early thirties, maybe. Jaw set. There were shadows under his eyes that had the specific texture of someone who had not slept because the thing they'd seen would not leave them alone when they tried.
Neither of them had moved when I'd tried to stand. Neither of them moved now.
The silence sat between us like a third person.
They want me to fill it, something in me noted, from somewhere that felt reflexive, instinctive — the same place that had noticed the door was behind me, that had catalogued the lamp and the cuffs and the quality of the floor. Don't.
I lasted six seconds.
"You ruined my hair," I said.
My voice came out steadier than I'd expected. The older one's expression didn't change. The younger one blinked once, which was at least something.
"I'm serious," I said, into the silence that followed. "I had done something with it. This morning. Or — at some point. And now it's—" I stopped. The sentence was going somewhere embarrassing. I let it go. "Could I get a towel."
The older one unclasped his hands. He pulled out the chair across the table from me, sat down in it, and folded his hands on the table surface. The younger one stayed standing. Neither of them produced a towel.
"State your name," the older one said.
His voice was flat. Not unkind. Just — flat, the way a surface was flat, because it had been made that way deliberately and maintained that way through consistent effort.
"Mikael Sanders," I said.
"Age."
"Twenty-two."
He wrote something down. A small notebook, I hadn't noticed it until now, pulled from an inside pocket. The younger one opened his folder.
"Do you know why you're here, Mr. Sanders."
I opened my mouth. Closed it.
Did I know why I was here.
I tried. I pushed inward the way you pushed against a door you weren't sure was locked — carefully at first, then with more pressure, searching for give. I found my name. I found my age. I found the fact that I had once done something intentional with my hair and that I apparently owned Victorian-cut clothes because those were what I was currently wearing, soaked through and starting to smell like wet wool.
Beyond that.
Nothing.
Not a dim memory. Not a blurred edge. Not the ghost of something that might become clearer with effort. Just a blankness so complete it had a texture to it — like pressing your hand flat against a wall in a dark room and finding no door, no window, no seam. Just wall. Just flat, continuous, total wall.
I was in a cuffed chair in a metal room with two Imperial Police officers and I did not know how I had gotten here. I did not know what city this was. I did not know what month it was. I did not know what I did for a living, who I knew, where I lived, or what I had been doing yesterday.
I knew my name. I knew my age.
That was the complete inventory of Mikael Sanders.
Don't say that, something told me, with an urgency that felt important. Whatever you do, do not say that out loud.
"I'd like to know what I'm being charged with first," I said instead.
The older one looked at me for a moment. Then he nodded at the younger one, who opened the folder and slid a photograph across the table.
Formal portrait. A man in his late fifties, broad-faced, well-dressed in the Dominion style — high collar, dark fabric, the kind of tailoring that announced its own expense without appearing to try. He had the look of someone who had been important long enough that importance had settled into his bone structure. Below the portrait, in the clean administrative typeface of official documentation:
VISCOUNT ALDRIC HUMBOLDT. UPPER SOUTHERN DISTRICT. DOMINION NOBILITY, SECOND TIER.
I looked at the photograph. I looked at it with genuine effort, searching the face for anything at all — a flicker, a pull, the edge of recognition.
Nothing. The man was a stranger.
"Do you know him," the older one said.
"No."
"Look again."
"I have looked. I don't know him."
The older one's pen moved in his notebook. I couldn't read what he wrote from this angle and the handwriting was too small to attempt it.
"The Viscount is dead," he said, without looking up.
The words landed in the room and stayed there.
I waited for something to follow them inside me — guilt, grief, surprise, anything with a shape. I found only the blankness, patient as ever.
"I'm sorry to hear that," I said. It sounded wrong. Too measured. The older one's pen stopped moving. "I mean — that's — when?"
"Three nights ago." He looked up. "The fourteenth. At his estate. Harwick Hall, Upper Southern District." A pause. "You were there."
"I wasn't."
"Three witnesses place you in the east corridor between nine and eleven in the evening."
"Then three witnesses are mistaken."
I said it too fast. I heard it the moment it left my mouth — the particular speed of a denial that didn't have anything behind it, no timeline, no alternative, just the reflex of a man saying no because yes was worse. The younger one's eyes moved to the older one's face. Something passed between them too quickly for me to read.
Slower, I told myself. You're panicking. Stop panicking.
"Three witnesses," the older one said. "Independent. Not acquainted with one another. All three place you in the east corridor on the night in question." He set his pen down on the notebook. "One of them describes a conversation between you and the Viscount that lasted approximately twenty minutes."
"That's not possible."
"Why not."
Because I don't remember it. Because I don't remember anything. Because I woke up in this chair with nothing behind my eyes and no idea how I got here and you are describing a night I cannot account for in any direction.
"Because I didn't know the man," I said. "Why would I spend twenty minutes talking to someone I didn't know."
"That's what I'm trying to establish," the older one said.
The lamp hummed. Water dripped from the hem of my jacket onto the stone floor. The younger one turned a page in his folder without looking at it, a fidgeting gesture he probably wasn't aware he was making.
They're not telling me everything, I thought. They're feeding it in pieces. Watching what each piece does to my face.
I straightened in the chair. The cuffs pulled at my wrists and I forced myself to stop noticing them.
"All right," I said. "Let's say I was there. Let's say the witnesses are correct and I was in the east corridor and I spoke to the Viscount. That doesn't tell you anything about what happened to him. People speak to each other at events. It's not—"
"The Viscount burned," the older one said.
I stopped.
"In the ballroom," he continued, in the same flat voice, as if he were reading from the notebook rather than speaking from memory. "At approximately eleven forty. In front of approximately two hundred guests. He was standing near the east entrance when it began." He paused. The pause was not dramatic. It was the pause of a man being precise. "It took four minutes. There was no fire. No heat source. No accelerant identified. No Torrent Machine was discharged in the room. He burned from the inside." Another pause. "What remained was ash. Structural ash, in the outline of a standing man. It had cooled by the time our officers arrived."
The room was very quiet.
Four minutes, something in me thought, despite itself. That's a sustained discharge. Not an accident. Accidents are instantaneous. Four minutes is—
I stopped the thought before it finished. Filed it somewhere. Kept my face at neutral, which was difficult, because my face wanted to do several other things.
"In front of two hundred people," I said.
"Yes."
"And no one — no one did anything."
"There was panic. Several guests were injured in the evacuation. Three fainted." The older one's tone remained clinical. "By the time anyone with a Torrent Machine had the presence of mind to attempt intervention, there was nothing left to intervene on."
I looked at the photograph of the Viscount. At the broad, settled face of a man who had been important long enough that it had become structural. I thought about what the older one had just described — a man burning in the middle of a ballroom, four minutes, inside out — and I thought about the fact that the last person seen speaking to this man was apparently me.
And I thought about the capital statutes.
The thought arrived with the particular quality of cold water hitting skin — sudden, total, leaving no part of the body untouched. Noble blood. Second tier Dominion nobility. The Aristocratic Preservation Statutes, which I knew about from the same place I knew about everything else I apparently knew — some recess of myself I couldn't access directly — were not ambiguous on the subject. The unlawful taking of noble life. One finding. One outcome. No appeal, no commutation, no lesser court.
I was in a cuffed chair being questioned about the death of a Viscount.
I'm going to be executed, I thought. For a man I've never met. In a city I don't know. With no memory, no alibi, and no idea how any of this happened.
The joke arrived before I could stop it — at least the hair will grow back before the sentence is carried out — and I recognised it for what it was: my mind finding the nearest available exit from a thought it could not finish.
The older one was watching my face.
"The witnesses," I said. My voice came out measured. I was concentrating very hard on measured. "You said three of them placed me in the corridor. The same witness described the conversation?"
"Two of the three reported the conversation. The third places you in the corridor but did not observe the exchange."
"And their accounts—" I hesitated. Careful. "Did they agree. On what they saw."
The older one looked at me.
It was a short look. Two seconds, perhaps three. But something moved through it that hadn't been there before — a slight recalibration, the same shift I'd noticed earlier, the quality of a man deciding how much of a gap to show.
"Witness accounts are part of an ongoing investigation," he said.
Which was not an answer. Which was, in fact, the specific shape of a non-answer that sat exactly where an answer should have been, and the shape of it told me more than a yes or no would have.
They didn't agree.
I didn't know how I knew that. I knew it the way I knew the cuffs were hinged, the way I knew the capital statutes, the way I'd known things all morning from a place inside myself that I couldn't find the door to. The witness accounts had not been consistent. Something about the Viscount's death — the event itself, the room, the aftermath — had made the accounts irreconcilable in ways the officers couldn't explain.
Why.
I reached for it — the answer, the mechanism, the thing that would make the inconsistency make sense — and felt something shift in the back of my mind. Something I could almost touch. A framework. A structure. The edge of a language I apparently spoke fluently and couldn't remember learning.
I let it go. The timing was wrong. I needed to understand where I was before I started understanding what I knew.
"I want to be cooperative," I said, carefully. "Genuinely. But I'm struggling to account for my whereabouts on a night I have no clear memory of." I looked at the older one. "If you could tell me — what exactly do you believe I did. Not what the witnesses say. What you believe."
"We're not here to share our beliefs," the older one said.
"Then what are you here for."
"To establish the facts."
"The facts as you have them," I said, "are three inconsistent witness accounts placing me near a man who subsequently burned to death in a room full of people. That's not a fact. That's a proximity." I paused. "Proximity isn't culpability. Even under the Preservation Statutes."
The younger one's head came up.
It was a small movement. A degree or two. But I caught it because I was watching him — watching him the way I'd been watching both of them since the water hit me, cataloguing, filing, trying to build something useful out of the pieces they were giving me.
He hadn't expected me to know the Statutes.
I hadn't expected me to know the Statutes either, if I was being honest with myself, which was a conversation I was actively avoiding.
"You have legal training," the older one said. It wasn't a question.
"I'm aware of the relevant law," I said, which was true in the most technically accurate and deeply useless way possible.
The older one studied me for a moment. Then he said: "The Viscount had filed three formal requests for additional Imperial Guard protection in the six months prior to his death."
I said nothing.
"Three requests. All denied. The official reasoning was insufficient evidence of credible threat." He paused. "The requests cited a specific concern. A belief that he was being watched. That someone with knowledge of his work had taken an interest in him."
"What work," I said.
The older one looked at the younger one. The younger one turned to a specific page in the folder. He did not slide it across the table. He read from it without showing it to me, which was its own kind of information.
"The Viscount was a practicing mechanomancer. Class III certification. In the two years prior to his death he had been engaged in private research — unlicensed, conducted at the estate rather than through any registered institution." The younger one's voice was careful. Recitative. The voice of someone reading a document they had complicated feelings about. "The nature of the research was classified at his request under Dominion private scholarship protections. We've been unable to access the full record."
"But," I said.
A pause.
"His personal correspondence indicates he was attempting to develop a new arcanomechanical sequence," the younger one said. "One that incorporated—" He stopped. Looked at the older one.
The older one gave him nothing. Just waited.
"Biological material," the younger one said finally. "Of a specific origin."
The room was very still.
I looked at the folder in the younger one's hands. I looked at the page he was reading from, which he was still not showing me. I looked at the photograph of the Viscount, broad-faced and settled and three days dead.
Biological material of a specific origin.
I didn't ask. I had the sense — from nowhere, from the same place everything else came from — that asking directly would close a door rather than open one. So I filed it. Stored it with the inconsistent witnesses and the four-minute burn and the six months of unanswered security requests.
The structure was assembling itself slowly in the back of my mind, load-bearing walls still missing, most of the architecture still dark. But the outline existed. The Viscount had been afraid. He had been working on something he wouldn't register, something that used material he wouldn't name, and someone — or something — had found him anyway.
And I had been the last person seen talking to him.
"The conversation," I said. "The one the witnesses described. Twenty minutes, in the east corridor." I kept my voice level. "What did they say we talked about."
"One witness reported the Viscount appeared distressed," the older one said. "Agitated. The word used was desperate." He looked at me steadily. "The same witness reported that after the conversation ended, you walked away toward the west staircase. The Viscount remained in the corridor for several minutes before returning to the ballroom." A pause. "He burned approximately forty minutes later."
Desperate.
The word sat in the middle of my chest with a weight I didn't know what to do with. A man I didn't know, afraid enough to file three security requests, desperate enough that a stranger could read it on him across a crowded corridor — and that stranger had apparently been me, and I had walked away, and forty minutes later—
Stop.
This was not productive. Guilt about a man I didn't remember meeting, for an event I couldn't account for, was the least useful thing I could spend the next few minutes on. The most useful thing I could spend the next few minutes on was finding a reason — any reason, preferably one that wasn't a complete fabrication — why the evidence against me was insufficient for a capital finding.
The witnesses didn't agree. That was something. That was a thread.
Pull it.
"The witnesses," I said again. "I want to come back to the witness accounts."
"We've addressed—"
"You said they didn't agree." The older one started to object and I pushed through it, carefully, keeping my voice at the same measured level. "You didn't say that. But you didn't not say it either, and the gap between those two things is the most interesting part of this conversation so far." I watched his face. "Three independent witnesses to the same corridor, the same time window, the same person. If their accounts were consistent you would have told me they were consistent. You would have used it. You didn't." I paused. "So what didn't they agree on."
The older one was quiet for long enough that I started to think he wasn't going to answer.
Then: "Details," he said. "Small ones."
"Such as."
Another pause. He seemed to be deciding something. "One witness describes your coat as dark grey. One describes it as black. The third doesn't mention a coat." He looked at me. "One witness places the conversation starting at approximately nine fifteen. Another says closer to nine forty-five." A beat. "One witness reports that after the conversation you moved toward the west staircase. Another says the east."
I looked down at my jacket. Dark grey. Or black, depending on the light.
"That's not unusual," I said. "Eyewitness accounts are notoriously unreliable. Time perception, color perception — those are the first things to go under stress."
"There wasn't stress at nine fifteen," the younger one said. "The Viscount hadn't burned yet."
"People misremember even mundane events," I said. "That's established. A defense advocate would—"
"This isn't going to a defense advocate," the older one said.
The flat certainty of it stopped me mid-sentence.
"Pardon?" I said.
"A capital finding under the Preservation Statutes goes to a Tribunal, not a court." He said it the way he said everything else — without inflection, without cruelty, with the precision of a man conveying information rather than delivering a threat, which somehow made it worse. "A Tribunal is not an adversarial proceeding. There is no advocate. There is a panel of three Noble Adjudicators who review the evidence and determine sufficiency." He looked at me. "The evidentiary standard for sufficiency is lower than you may be assuming."
Lower than I may be assuming.
I thought about the witnesses who didn't agree on the color of my coat. I thought about whether three Noble Adjudicators, looking at three accounts that placed a non-invited man in conversation with a Viscount forty minutes before that Viscount burned to death in his own ballroom, would find that sufficient.
I thought they probably would.
My hands were sweating. I could feel it against the iron of the cuffs, the specific clamminess of a body that was frightened regardless of what the face was doing. I pressed my palms flat against the chair back and focused on the sensation of it — solid, real, present — and breathed through my nose for a count of three.
All right, I thought. All right. Think. You are allegedly a genius. Now would be an excellent time to demonstrate that.
The witnesses didn't agree. Four minutes of sustained burn with no external source. A Torrent Machine that hadn't been fired. A man who had been afraid for six months. Research into something biological, something he wouldn't name, something classified under private protections that even the Imperial Police couldn't access.
And the accounts that didn't match — not just on my coat, not just on the time. On the direction I'd walked after the conversation. East and west. Opposite directions. Two witnesses, two irreconcilable spatial memories, from the same corridor, the same night.
Why.
The framework in the back of my mind pushed forward again. I let it, this time — let it surface far enough to look at the shape of it without touching it directly. Something about the night itself. Something about the conditions in the Harwick Estate east corridor at nine fifteen or nine forty-five or whatever time the conversation had actually happened. Something that had made every memory formed in that window slightly, fundamentally, irreconcilably wrong.
I didn't have the word for it. The word was there — I could feel the shape of it, just outside reach — but I didn't have it yet.
"I need you to tell me something," I said.
The older one waited.
"The guests at the Ball. After the Viscount burned." I picked my words carefully, watching the older one's face for the small movements that told me more than his words did. "Were there people who couldn't remember things clearly. Not just the burning — the whole evening. People who were certain about details that contradicted each other. Not confused. Certain. Just wrong."
Something happened in the older one's face. Not much. A fractional tightening around the eyes, the specific quality of a man who has been asked a question he didn't expect and is deciding how to handle it.
"Why would you ask that," he said.
"Because it would explain the witness accounts," I said. "The discrepancies. If something happened in that building — not the burning, something before it — that affected how people were encoding memory, you wouldn't get inconsistency from confusion. You'd get inconsistency from certainty. Everyone absolutely sure they're right. Everyone wrong in a different direction."
The younger one had stopped pretending to look at his folder.
"What kind of something," the older one said.
"I don't know," I said, which was true. "But I think you've been assuming the accounts don't match because witnesses are unreliable. I think they don't match because something made them unreliable. Specifically. That night. In that building." I paused. "Which is a different problem."
The older one looked at me for a long time.
Then he said, very carefully: "What do you know about the Viscount's research."
"Nothing," I said. "You haven't told me what it was."
"You said biological material of a specific origin," the younger one said quietly.
"You said that," I said. "I repeated it."
"You didn't ask what it meant."
I opened my mouth. Closed it.
He was right. I hadn't asked. I had filed it and moved on, the way you moved on from something you already understood, or thought you did — and now both of them were looking at me with the specific quality of attention that meant they had noticed the thing I hadn't done.
"I assumed you'd tell me when you were ready to," I said.
It was a poor answer. The older one's pen moved in his notebook.
"Mr. Sanders," he said, not looking up. "I'm going to ask you something and I want you to think carefully before you answer."
"All right."
He looked up. "The marks on your left forearm. When did you get them."
I went very still.
Marks. On my left forearm. I hadn't — I hadn't looked. Since I'd woken up I hadn't looked at anything except the room and the men in front of me and I hadn't thought to look at myself because there had been no reason to think there was anything to look at.
I looked down. My jacket sleeves were soaked through and clinging, and through the wet fabric of my left sleeve I could see — barely, just the edges — something dark against the skin. A pattern. Small. Deliberate-looking.
I couldn't see the full shape of it from this angle with my wrists locked behind the chair.
"I don't know," I said.
"You don't know when you got them," the younger one said.
"I don't know what they are," I said, and this time the honesty sat differently in my mouth — not strategic, not measured, just true in the flat and frightening way that true things were when you didn't want them to be.
The older one nodded, once, slowly. He wrote something in his notebook. He capped his pen.
"We're going to take a short break," he said. He stood up from the chair. The younger one closed the folder. "We'll bring water."
"A towel," I said. "Please. I meant it about the hair."
Neither of them responded. The older one moved toward the door — behind me, I couldn't see it — and the younger one followed. I heard the mechanism of it, iron on iron, and then the sound of it closing.
And then I was alone.
I sat in the cuffed chair in the orange half-dark and I looked at my left arm and I thought about marks I didn't recognise on skin I apparently didn't know, and I thought about a Viscount burning in four minutes with no external source, and I thought about a research project involving biological material of a specific origin that the officers had not been willing to name.
And I thought about the younger one's voice when he'd said it. Biological material. The way he'd stopped and looked at the older one first. The way the older one had given him nothing, just waited, and the younger one had found the most neutral possible word for the thing he was describing.
Of a specific origin.
I stared at the marks on my arm through the wet fabric of my sleeve.
Old Blood.
The words arrived from nowhere, from the same place everything arrived, from the dark inventory of things I knew without knowing how I knew them.
I had absolutely no idea what to do with that.
The door opened twenty-two minutes later. I had counted. It was the only thing I had been able to do with any precision in the interim, and precision, I was discovering, was what I reached for when everything else had been taken away.
The older one came back alone.
No younger one. No folder. Just the officer, and a tin cup of water which he set on the table in front of me, and a look on his face that was the same look it had always been — clinical, processing, a man examining a variable — except that something had been added to it that I didn't have an immediate word for.
"Your associate," I said. "Not joining us."
"He's following up on something." The older one sat. "Drink your water."
"My hands are behind my back."
He looked at the cup. Then he stood up, moved around the table, and held the cup to my mouth without ceremony, the way you watered something you weren't sure was worth the effort. I drank. The water was cold and tasted like metal pipes and it was the best thing I had experienced since waking up.
"Thank you," I said.
He set the cup down and returned to his seat.
"I want to ask you something," I said.
"You're not in a position to ask questions."
"You asked me about the marks on my arm," I said. "Before the break. You'd noticed them before you asked — you'd had time to notice them, you just waited. Which means you knew what you were looking at, or thought you did, and you wanted to see if I knew too." I looked at him. "What did you think they were."
The older one said nothing.
"Because I've been sitting here looking at my own arm for twenty minutes," I said, "and I can't see the full shape from this angle. And I'd quite like to know what's on my body that two Imperial Police officers keep looking at and not explaining."
The silence held for a moment.
Then the older one stood, came around the table again, and crouched down beside the chair. He pushed my left sleeve up — not roughly, with the same clinical efficiency he did everything — and I looked down at my own forearm for the first time.
The marks were small. Dark, almost black against my skin. They covered the inside of the forearm from wrist to elbow — not random, not decorative. Structured. Precise. Lines and intersections and nested shapes that meant nothing to me visually but which produced, when I looked at them, the same reaching sensation I'd been feeling all morning. Something my mind was trying to touch and couldn't.
The older one looked at them for a moment. Then he rolled my sleeve back down and stood up.
"We had a consultant look at the case," he said. He returned to his seat. "Yesterday. Someone with specialist knowledge relevant to the evidence recovered from Harwick Estate." He sat. He looked at me. "He identified the discharge signature from the Viscount's remains."
I waited.
"He told us what equation had been used," he said. "Or — what class of equation. The specific form." He paused, and the pause had a quality I hadn't heard from him before — the quality of a man handling something that had surprised him and hadn't finished surprising him yet. "He said it hadn't been practiced in over forty years. That every record had been destroyed. That every practitioner who'd known it was dead."
The lamp hummed. Somewhere in the walls, a pipe contracted in the cold.
"Then he looked at our evidence log," the older one said. "The items recovered from the Viscount's private study. The research materials." Another pause. "He went very quiet. And then he asked us where we'd found you."
I looked at him.
"We told him," the older one said. "We told him where our officers had located you the morning after the fourteenth. The specific location." He looked at me with that clinical, processing attention — the look of a man examining a variable he couldn't classify. "He said that wasn't possible."
"Why," I said. My voice came out even. I didn't know how.
"Because the location was inside the Harwick Estate perimeter," the older one said. "In a sub-basement room that doesn't appear on any architectural record of the building. In a room that, according to our consultant, couldn't exist — because the space it occupies is the same space as the Estate's primary structural foundation." He looked at me. "You were found, Mr. Sanders, inside solid stone. Sitting in a chair. Unconscious. With no visible means of entry or exit."
He reached into his jacket and placed something on the table between us.
A single sheet. Dense notation. Lines of arcanomechanical script that I could read — immediately, fluently, the way I read my own name — and at the bottom, a terminal sequence I recognised before I had consciously processed the rest.
The equation. The one that had killed the Viscount.
I knew it. Not the way you knew a thing you had studied. The way you knew your own handwriting. The way you knew the weight of a door you had opened a thousand times.
"Our consultant," the older one said quietly, "said the marks on your arm are a notation system. A very old one." He looked at me. "He said the last person documented using that system died before either of us was born."
He waited.
"Mr. Sanders," he said. "Who are you."
The lamp hummed. The water dripped. Somewhere in the distance, muffled by stone and iron and the specific silence of a building that did not want to be heard, something that might have been machinery pulsed once and went quiet.
I looked at the equation on the table.
I looked at my arm.
I looked at the older one, who was watching me with the face of a man who had come here to close a simple case and was no longer certain what case he was in.
And I thought: I have absolutely no idea.
