She found it because a book fell.
The botany encyclopaedias on the east shelves were enormous—the kind of volumes produced in an era when comprehensiveness was understood as a form of moral virtue—and the top shelf of them hadn't been touched in what appeared to be several decades. When she climbed the ladder to pull the last volume for the catalogue, its spine came away in her hand, and in falling it knocked loose something wedged behind it, which dropped to the floor with a flat, decisive sound.
A journal. Brown leather, worn at the edges. A brass clasp that needed persuasion.
She came down the ladder and picked it up, and felt something she had felt occasionally since arriving here—not memory, which would have been impossible, but something closer to familiarity than strangeness. The sensation of recognising the end of a sentence she hadn't known she'd read the beginning of.
She opened it.
The handwriting was small, neat, feminine—the hand of someone who had learned to fit a great deal onto each page. The first entry was dated seventy years ago, the year of Samuel's grandfather's tenure.
I, Catherine Harding, take up the position of housekeeper to the Earl of Blackwood today. I intend to serve this house as well as it can be served.
Ella sat down on the library floor and read.
Catherine had not kept a conventional household journal. What she had kept was an intelligence record—written in the careful, self-obscuring style of someone who understood that the book might be found by the wrong reader, full of compressed references and personal codes that Ella worked through in the first pages and then followed readily enough.
What she had recorded was this: the framing of the sixth earl for treason had been a coordinated operation. The architects were two court officials whose descendant lines led directly, in the present day, to Warwick's family and to Lawrence's father's closest ally. The motive was the northern harbour—whoever controlled it controlled a third of the regional trade revenue, and the earldom was the only thing standing between that harbour and the men who wanted it. Catherine had obtained evidence of the scheme: copies of correspondence, a witness account, a record of the false document's preparation. She had not been able to use any of it. She had been a housekeeper, alone, without resources or allies. So she had hidden the materials in three locations on the northern estate, and she had written down where, and she had placed this journal behind the botany encyclopaedias, and she had hoped.
The last entry was written in a shakier hand. She had been ill.
I have done what I could. I hope that one day someone finds this. I hope they are able to do what I could not.
Ella sat on the library floor for a long time.
Seventy years. The same house, the same family, the same enemies, the same harbour. A woman doing the same work alone, without anyone to hand it to, leaving everything she had found in the dark and trusting that someone would eventually come.
The resemblance sat in her chest, heavy and specific.
She took the journal. Locked it in her desk. Went to find Elias, told him what she'd found without editorialising, and let him respond.
"Not yet," he said. "His stability is improving but this would be a significant shock. The evidence, the confirmation that it goes back further than he knew—if he receives it before he's ready, it becomes a pressure. Wait until he's steadier."
"How long."
"A few weeks. I'll tell you."
"All right," she said.
That night, she copied out the key details from the journal—the three hiding places, the names, the nature of the materials—and locked the original away. She carried the copy close.
She thought about Catherine's last entry. About the particular quality of hope required to hide something and walk away from it, trusting in a future you can't see.
The future had arrived. It had taken seventy years, and it was a woman from a century that didn't exist yet, in a body that wasn't originally hers, working a case she'd come to backwards.
But it had arrived.
