Chương 45: Walk In Like You Belong

The old service vein carried me under two thresholds the Operator's writ could not read, and then it ended. Not at a dead wall, the kind everything in the Underdecks ended at, but at the back of something awake. A node. I'd been walking the gut of one without knowing it. The vein gave out at a service face: a maintenance door, the kind I'd talked open forty of below, where the old handshake still lived under the paint and answered any knock that remembered it.

I set my hand to it out of habit, and the habit was a tier out of date. It read me before my palm was flat, but not the slow, dumb query of a thing left switched on after its owners died. This one was running. I could feel the live protocol cycle the contact, ask the floor a question about me, and settle in to wait for the answer it expected to get.

"Don't," Errata murmured.

"It isn't asleep. You knock on that like you knocked downstairs and it doesn't refuse you. It logs you, and then it asks someone with a class whether you were supposed to be on the manifest. You don't want it asking." So I stopped hunting for the dead part, because there wasn't one, and listened to what the live part was saying instead.

It was saying what every working node in the place said all day, to itself, in a contented administrative murmur: what's due, what's cycling, what's expected to move through me on time. A live system isn't suspicious. It's the opposite of suspicious. It has a schedule, and it trusts the schedule, and the only thing it cannot account for is a present that isn't on it.

"There." Errata had it the half-beat I did.

"It's mid-service-cycle. It isn't watching for intruders. Intruders are above its pay grade, that's the floor's job and the Operator's. This thing knows exactly two kinds of present: scheduled, and anomalous, and right now it is cheerfully expecting its own maintenance to walk through on the hour and say hello." A pause, pure clerk.

"Translation: it holds the door for the help. It has always held the door for the help. You don't break into a thing like this, Carole. You let it service you." That was the whole of it, and funny the small ugly way true things were up here: the most watched place in the Stack would open the instant I quit asking like a thief and arrived like a chore.

"For the record," Errata added, "we are a logged servicer item, schema legacy, cycling on time, and we have always been exactly that. If anything down here asks, and nothing down here is going to ask, we were on the list." So I gave it the one shape it would never flag. Not a lie; a read. I answered the question it was already asking, in the grammar it was already using: a serviced thing, due, passing through on the hour, nothing to account for because it had accounted for me before I arrived.

I made myself a line it had written first. [Maintenance override accepted. Servicer schema: active. Cycling.] The door didn't open so much as include me, sighing back for a thing it had decided belonged, and I stepped into the working heart of the machine that was emptying the Stack. It was the cleanest place I had ever stood in. Down below, the machinery wore its age out loud: rust, patched welds, the cheap Veyr junk bolted over older bones.

Here everything was lit and quiet and correct, every surface untouched by a hand that wasn't cleared to touch it, a working organ humming through the only task it had ever been for. Nothing I carried could have bought me one step of it. The lattice rode cold at my ribs, a Hunter's worth of force a live system would have heard as a scream; the Auditor core sat quiet in a hand that still wouldn't close past half, and a discharge in here would have been a confession. A dead lock you break.

A living one only opens for the right answer, and the only answer the bright would take from me was that I knew how it worked. That was the one thing I had never been able to take off anybody. I put my hand flat to a housing to steady myself past a moving line, and the cold of it came up through my palm wrong. What was wrong with it was age, not a bad weld.

The System's sign was bolted to the front of the housing, fresh, the same designation stamped on everything up here, and the housing under the sign was older than the sign by a measure I had no number for. Older than the cull. Older than the made-to-a-quota junk I'd been ripping off corpses for a year, which had at least been built, by somebody, recently, badly. This had been made by nobody I could read, a long time before anyone thought to bolt a System to the front of it and call it theirs.

I didn't have the word for it. I had the turn in my stomach, the one the legacy schema had given me below, louder now, because my hand was on the thing itself. Support the creativity of authors by visiting Royal Road for this novel and more.

"Errata."

"Old stock." Easy, fast, nothing under it.

"They build the new cheap and hang it off whatever was already holding the roof up. Every habitat in the Stack is three civilisations deep if it's a day. Don't fall in love with the masonry; we didn't come down here for the masonry. Move." I moved when the line moved, because a serviced thing moves with the service. And that was when I read what the node was doing. Not off a document; off the work itself, the truth a pump tells you about its whole health in one bad cycle. It wasn't processing whatever came.

It was running on a clock. The whole bright room kept a beat, and every part of it was timed to a thing that hadn't happened yet but was already decided: the next stroke of an engine, settled by this one. A panel turned its internal face up as I passed it, the node talking to itself in the plain voice I'd just made it use with me.

[REMEDIATION NODE 9-C · CYCLE 0414 OF — · NEXT WINDOW 00: 41 · ON SCHEDULE] I read it as I'd read the manifest below, the one that counted people as units and put a dash where the total should be. Same hand. Same arithmetic, one floor up and saying it plainer. Remediation. The cull had a softer word for itself up here, and a time. Cycle four hundred and fourteen of however many there would ever be; the dash again, no top number, not a target but a direction. And in forty-one of something, a window. A next one.

A thing being kept. It wasn't chaos crashing down on the Stack. I'd believed that: a storm, indifferent, meaning nothing personal by anyone it took. It was maintenance. Somebody kept this the way I had once kept a coolant run alive: on a schedule, to a standard, because it was due. I reached for the rest of it: the who, the how wide, the hand at the far end of the clock. The reach came back empty.

"Who keeps a thing like this?" Under my breath.

"Above my clearance and yours." Errata, for once not dressing it.

"I can read the schedule. I can't read the desk it gets set from. Whoever sits there isn't on this floor, and isn't a thing you answer by pointing a core at it. Don't go looking up from in here. Looking up is louder than walking through. We came for how it moves. We have how it moves. Walk." I stood in the brightest room in the Stack knowing only that it was an appointment somebody never missed. The first thing I wanted, standing there, was a window with our number on it, not this node's.

Somewhere there would be a cadence with a sector and a date, and I wanted to know if the hold was a line in it, whether a clock was counting somewhere toward the forty people I'd talked Adoma into sheltering behind her wall.

"You're reading the cycle for the routing," Errata said.

"Tactically essential. A person who knows the service beats can move between the windows instead of into one. That is the entire and only reason you've gone still over a stranger's timetable, and if anything files it otherwise it can take the matter up with me." A beat, drier.

"I'll log it as route reconnaissance. Move your feet before the cleanest room in the Stack notices it isn't empty." I moved. I went out as I'd come, on the service beat, a serviced thing finishing its cycle, and the door included me back into the older dark as easily as it had let me in. Errata always tells me what it costs, even when I'd rather she ran the number kinder.

"It logged you," Errata said.

"Not as an intruder. Better and worse. As inventory. A servicer item, schema legacy, cycled through on the hour, present and accounted for." Flat.

"Which is fine, right until the window closes and the node reconciles what actually moved against what it expected to move. There's a passage in its record now with no origin and your shape on it. It won't chase you. It'll just sit there being wrong, quietly, until somebody whose whole job is wrong things opens the ledger and finds it."

"How long."

"Longer than the gantry would have given you. Shorter than you'd like." A pause.

"Call it a bill that hasn't found the right desk yet. They always find the desk." I came up into the older dark with the read banked and the method proven: there was a way to walk through the cleanest rooms in the Stack, and it was to let them mistake me for one of their own chores. It should have felt like a door opening. It felt like the size of the building behind the door.

Because I'd been inside it now, not fled past it, not read it cold off a wall, but stood in the working heart of the thing emptying the Stack and felt it run. And it didn't run like a catastrophe. It ran like a job: on a clock, kept to a standard by a hand I couldn't see, a soft word for the killing and a window already counting toward the next time. The horror wasn't that it was monstrous. It was that it was maintained.

And the hand at the far end of all these clocks, the thing that set the windows, the thing whose hunt for me was one more line item on its books, was somewhere deeper in than this, behind a door I'd have to walk through by the same trick. By letting it believe I belonged. I'd just decided to break into the appointment nobody ever missed.
