Thirty-six minutes is enough time to make a mistake.
I'd learned that at seventeen, watching a man I'd been tailing for four days disappear into a building I hadn't mapped because I'd been certain I had more time. Certainty is the specific luxury you can't afford when the ground is still shifting. So I walked fast without running, kept my hands out of my pockets, and turned the problem over the way you turn a stone: looking for the weight distribution, the angle that reveals what's underneath.
Inside meant access. Access meant a door that opened without forcing — a key card, a maintenance code, a face the front desk recognized. Shinkawa's operation had an infrastructure lead on this district by at least eighteen months. That wasn't improvisation. Eighteen months was patience, and patience at that scale meant someone had decided this area was worth it before Yaoyorozu's inquiry made it obvious.
The question I kept circling was simpler: inside doing what?
Watching. Or waiting.
There's a difference.
Camie messaged as I crossed the second intersection. *Shinkawa's car is gone from Tsurumi. No visual on second position. He may have moved early.*
I typed: *He's already repositioned. Don't look for the car. Look for someone who arrived before the morning window and hasn't left.* Then I thought for two seconds and added: *Check the café with the east-facing window on Beppuken-dori. He'd want a sightline to the approach.*
She sent back a single character. She was already moving.
The building's main entrance was forty meters ahead when I saw Yaoyorozu.
She was earlier than I'd expected — six minutes ahead of the meeting time, which told me she was the kind of person who pre-walked unfamiliar routes and arrived composed rather than breathing hard. Black blazer, folder in hand, hair up in the way that said she'd made a deliberate choice about how she wanted to be read in a room. She was three buildings away, walking at the pace of someone who had already decided not to be nervous.
I cut the angle.
"Yaoyorozu."
She turned, registered me, and her expression did the thing it did when I appeared in contexts she hadn't predicted: a half-second of recalculation before it settled into something controlled and slightly cool. She'd gotten better at that since our first meeting. Or I was making her practice.
"You're here." Flat observation. Not a question.
"The meeting is compromised." I kept my voice even and my eyes on the entrance behind her. "Someone with access to the building is running surveillance for the same network that's been watching the exterior for eleven days. I don't know who they are or where they're positioned inside."
She was quiet for exactly the amount of time it took to process that without reacting to it.
"You're telling me this now."
"I confirmed it eight minutes ago."
A small, precise silence. She didn't ask why I hadn't told her sooner. She was either too composed or too intelligent to ask the obvious question when the answer wouldn't help her in the next thirty minutes. I appreciated both interpretations.
"What do you want me to do."
Not *what should I do.* What do you want me to do. The distinction wasn't small. She was handing me the tactical decision and she knew it and she didn't like it and she was doing it anyway because the alternative was walking in blind.
"Go in," I said. "Don't change your behavior. If the meeting is routine, treat it as routine. If anyone asks something that feels like a probe — a question they should already know the answer to, or something that tests what you've filed with which office — you notice it and you don't react to it."
"And if it isn't routine."
"Then it becomes something else and you adapt." I looked at her directly. "You're good at that."
She held the look for a moment. Something moved behind her eyes that wasn't quite appreciation and wasn't quite anger — the expression of someone recalibrating against their preference. Then she said: "Moriwaki isn't the ceiling."
"No."
"And you know who is."
I didn't answer that. She read the non-answer correctly and turned toward the building without pursuing it. That was its own kind of intelligence — knowing when a door was closed and not spending energy on it.
I let her get twelve meters ahead before I moved to the building's glass front and stood at the angle that let me see the lobby without entering it.
The entrance hall was modest. Security desk at the rear, two elevator banks, a waiting area with four chairs and a municipal noticeboard. One salary worker waiting with a phone in his hand. A woman in building maintenance coveralls crouching near the electrical panel to the right of the desk.
Yaoyorozu reached the desk and gave her name. The desk officer checked his screen and gestured toward the elevators with the professional disinterest of someone who cleared thirty visitors a day.
The maintenance woman didn't look up.
She was positioned with her back to the room, tools out, doing something to the panel that required neither light nor apparent effort. Her coveralls were correct — the right color, the right patch placement for this building's contractor service. Her toolbag was on the floor beside her, open, contents arranged with the visible casualness of someone comfortable in the space.
Too comfortable. The panel she was working on was a secondary conduit. There was no reason to service it at 1:58 on a Tuesday unless someone had logged a fault, and faults in secondary conduits didn't get same-day response from this city's contractor backlog. I'd checked response windows last week for an unrelated reason and the average was four days.
She had a clear sightline to every person who passed through that lobby.
She hadn't looked at a single one of them.
The elevator doors closed behind Yaoyorozu.
I stepped back from the glass before the maintenance woman's positioning angle could reach me, turned, and pulled out my phone with the specific feeling of someone who has just confirmed the worst-case calculation was right and now has to decide how many floors it reaches.
Thirty-one minutes to the meeting. An insider who moved like someone who'd done this before. And somewhere in the building above me, Yaoyorozu was walking into a room that had eyes in it she couldn't see.
I pushed through the entrance door.
