We've been at it for two hours when I hear it.
Edvin's morning ritual has a rhythm I know the way you know the sounds of a place you've lived adjacent to for four years. Shutters at first light. Stool dragged to the drafting table. The particular squeak of the supply cabinet where he keeps his inks. Then quiet. The long productive quiet of a man doing precise work he loves, occasionally broken by the sound of a tool being set down or picked up.
That's all there ever is.
So when I hear a voice that isn't Edvin's, I stop mid-sentence.
Sera looks up from the land grant she's been annotating in the margins since an hour ago and goes still.
We listen.
Edvin's voice, below. Warm, unhurried, the tone of a man greeting someone he knows. Then the other voice being lower, male, a cadence I can't quite resolve into words through the floorboards but can resolve into something else entirely.
Practiced. Neutral. The voice of someone asking questions they already know the answers to.
I look at Sera. She looks at me. We move at the same time. She moves to the door, hand on the frame, head tilted to catch more of the sound; me to the window, checking the street below. One man visible at the corner, hands in his coat pockets, not looking at the shop. Looking at the street.
Watching it.
I hold up one finger. Sera nods, already clocking the voice downstairs as singular, which means the one outside is the second. Minimum two. Possibly more further back.
"Traveling merchant," Sera mouths.
They're asking Edvin about his tenant.
I watch Edvin's voice through the floorboards. The warm unhurried tone hasn't changed. He's answering the way he always answers questions about me, which is with the cheerful vagueness of a man who genuinely doesn't know very much and doesn't find that troubling. Irregular schedule. Pleasant enough. Pays in advance.
Contentment on his skin, warm as morning light, completely unbothered.
He's not in danger. He doesn't know enough to be in danger. That's the only good thing about this.
Sera appears at my elbow. "Back the way we came?" she murmurs.
"They'll have it covered," I murmur back. "They're not amateurs." I think. The street exit is watched. The back passage we came in through is certainly covered, anyone who knows about me knows about the back. The roof is possible, if we can get to the skylight at the end of the upper hall without the stairs announcing us.
Fourteen steps in. Third and seventh creak.
"Roof," I say. "Skylight at the end of the hall. We go one at a time, slow."
"The files," she says.
I look at the wall. At fourteen months of work, with the maps, the documents, the Cayne evidence, the seventeen land transfers, the thread I have been pulling alone since before any of this began.
I can't take it all. There isn't time.
I take three things: the oldest land grant, the Cayne dissolution record, and a single folded paper from the locked box in the desk drawer. It was the one thing in this room I haven't shown Sera yet, the one piece I haven't been able to place, a name written in handwriting I don't recognize on paper that is older than anything else I own. I've been carrying it for six months without knowing what it means.
I tuck all three inside my coat.
Sera has already gathered her folder, the assessor's documents, Drev's folded paper – all of it, everything she came in with, secured and ready. She didn't need to be told.
We go into the hall.
The staircase stretches below us, narrow and wooden and communicative. Third step. Seventh step. I move along the wall where the boards are oldest and tightest, weight distributed, breathing even. Behind me Sera moves the same way, watching my feet, placing hers in the same relation to the wall.
Below us, Edvin's voice. Still warm. Still unhurried. The other voice asking something else.
Eight steps. Ten.
The seventh creaks.
Not much. A small sound, the kind that gets swallowed by the ambient noise of a city morning, the kind that means nothing to anyone who isn't specifically listening for it.
The voice downstairs stops mid-sentence.
We freeze.
Three seconds. Four. Five.
Edvin says something. I catch the shape of it without the words, the rising inflection of a man offering tea. The other voice resumes with a different cadence now. Shorter sentences. Moving toward the door.
They're leaving.
We don't move until we hear the shop door close. Then five more seconds, because I was trained by years of close calls to count to five after what sounds like safety before believing in it.
Then we go. Fast now, past the skylight and out onto the roof. Sera gets it open in four seconds flat, military efficiency, and I revise upward my estimate of how many times she's done something like this.
Varenthis spreads below us in the early morning light, gilded and rotten and entirely indifferent to what's happening on its rooftops. We move east, roof to roof, three buildings before we find a fire-stair that drops us into an alley that drops us into a market street that is busy enough to swallow two people without comment.
We walk. Normal pace. The art of disappearing into a city is the same as the art of not being remarkable, and neither of us is remarkable when we choose not to be.
Half a block. One block. The market noise closing around us like water.
"They knew the address," Sera says, quietly, into the noise. "Not just the street but the specific shop."
"Yes."
"From your room. When they searched it."
"Or from someone who knew someone who knew," I say. "The same way they found the bookbinder's." I think about Aldous, moving through the city below us like a current, reading everyone connected to everyone, finding the threads. "He's mapping us. Every person who's ever known anything about me, he's reading them. Finding the next connection and following it forward."
"He'll find Mira," Sera says.
The words land in the market noise and sit there.
"Mira has protocols," I say. "She knows what to do if the network gets burned."
"Cael."
"She knows what to do," I say again. Quieter. Less certain.
Sera doesn't push. She walks beside me through the market noise and doesn't push, which is either trust or the understanding that some things don't get better for being said out loud.
We need a third location. We need Mira. We need the access list that Mira was supposed to deliver this morning and hasn't. We need to know whether Drev got out of wherever he went after the canal.
What I have is three documents inside my coat, a knight who moves like a shadow and thinks three steps ahead, and the particular stubborn certainty that the Architect making his move means we're closer to the center of this than I thought.
Closer to the center means closer to the end.
"There's a place," Sera says. "In the Argent Wing's lower district. An old watch station that was decommissioned six years ago, officially demolished, actually just sealed and forgotten because the paperwork to actually demolish it was lost and nobody filed the replacement forms." She glances at me. "I know this because I was supposed to file the replacement forms."
"You didn't file them."
"I kept meaning to."
I look at her. At the face that decided to be honest and the eyes that are currently doing something that might, at a significant stretch, be described as innocent.
"Sera Vael," I say. "Did you keep a decommissioned watch station for personal use?"
"I prefer to think of it as institutional negligence," she says. "Which I have been meaning to correct."
The third time. Short, involuntary, suppressed in approximately half a second.
I keep counting.
