First Cut

The main draw valve was warmer than it should have been, and that told Tavo more than the schematic folded in his jacket ever would.

He crouched in the gap between two support ribs under the Varu Cistern Annex, bare fingers resting flat against the brass housing, and let the heat talk to him. Warm meant the governor upstream was already working harder than it should at this hour. That meant the second feed line he'd found from the scaffolding earlier that evening was still bleeding pressure off the main draw. That meant his own override key — the smaller one, the one he'd swapped for after reading that pressure drop — was still the right call.

He'd brought the heavy key too, strapped against his calf in case the small one lied to him. It sat there now, dead weight, a monument to every job that had ever gone exactly to plan. None of his had, so far.

Four minutes, eleven seconds — the loop he'd clocked Captain Sansu walking the hour he'd spent on the scaffolding, steady enough to set a clock by. That was how long he had before the patrol came back around the seawall walk overhead, if tonight ran true to the one pass he'd actually watched.

He fitted the key to the relief cap and turned it a careful eighth-turn, listening.

The hiss that came back was low and even, the pitch he wanted — the sound of Lift moving steady through a line that hadn't yet noticed it was being robbed. He held the key there, feeling the vibration climb up through his knuckles into his wrist, and started counting under his breath. Not seconds this time. Pressure.

A hundred count to a full draw, if the line held its rhythm. He'd worked the math on Bidan's slate three separate times before tonight, because a hundred count pulled at this rate filled the collection flask to the exact degradation line Bidan needed for the slow-burning dose, and a dose that burned slow was the only kind that bought Wela more than a single bad night's grace. Any faster on the valve and the governor meter upstream would notice the dip and sound. Any slower and he'd still be crouched here, hand on a stolen line, when the patrol's boots came back around.

Forty-one.

The flask at his hip filled by feel, a weight he tracked the way he tracked everything down here — not by looking, because looking cost half a second he didn't have, but by the small, specific drag against his belt that meant liquid where there'd been none.

Fifty-eight.

Water moved against stone somewhere above him, a long, patient slosh, the Annex's lower level breathing the way it did when the tide climbed toward the flush. High water was the only hour a month the lower housings sat open at all; miss it and this entire plan was nothing but theory and a wasted dose, a month from now, if Wela had a month to give it.

Seventy-three.

A whistle cut the dark above him — two short notes, then one long, a signal he'd never heard on the Annex's loop before tonight, which was reason enough to file it. He kept counting, kept the key steady.

Ninety-one.

The second whistle came back wrong.

Thirty seconds after the first — nowhere near the four minutes eleven the loop should have left him, which meant either somebody up there had skipped a relay post, or Sansu's loop had just collapsed from four minutes eleven down to something closer to thirty seconds. Either way, the schedule Tavo had built his entire exit around no longer existed, and it had stopped existing with that second whistle, while he still had nine counts left to pull.

He didn't stop the draw. Stopping now meant eating the whole risk for nothing, and nothing didn't buy Wela a slow-burning dose. Instead he reached sideways in the dark, found the second feed line by the cold brass under his fingers — the undocumented one, the one he'd traced from the scaffolding without ever learning where it went — and looped the collection line twice around its support bracket, cinching it tight enough that the flask hung braced against the pipe instead of swinging at his hip. The draw kept running, hands-free now, its pitch as steady as it had been a minute ago.

That left both hands for the problem that actually mattered: where to go that wasn't the ledge two sets of boots were already converging on.

His planned exit ran east along the dry access ledge — the route he'd scouted, the one that put him back at the surface grate with time to spare and nobody the wiser. He could hear the boots heading for exactly that ledge from two directions at once, which meant the clean exit no longer existed, and he had maybe four seconds to find out whether anything else down here did.

West, then. The relay tunnel he'd marked and discarded on his first pass. Too wet, he'd written on the schematic's margin, in handwriting that now looked like a man who'd never once had to actually use the thing he was dismissing.

Ninety-nine. One hundred.

He unlooped the line from the bracket in two motions and shut the valve, key still seated, and didn't wait around to admire the work.

Boots hit the seawall walk directly over his head. Two sets, moving fast, not patrolling.

So much for the plan surviving contact with reality. He'd have given it four minutes, generously. It had lasted exactly as long as the count and not one second more, which he supposed counted as an improvement over most of his life choices to date. A tradesman reviewing his own shoddy work would have docked him half his fee and told him to come back when he'd learned to budget for the weather.

The flask at his hip sat full and warm, and for one clean second Tavo let himself feel it — the whole job, the thing he'd actually come here to do, done. A single evening's scouting, a bounded debt to the Silt, a dose running low in his sister's blood, and it had all come down to a hundred-count on a valve that hadn't failed him.

The tunnel mouth sat half-swallowed by standing water, black and close, smelling of iron and something sourer underneath that he didn't let himself think about. He went in anyway, flask secured at his hip, collection line coiled tight in his free hand because leaving it behind meant leaving evidence that pointed straight back to tonight's withdrawal.

The water hit him at the knee first, then the thigh, cold enough to steal the breath out of him before he could brace for it. He thought, absurdly, of Wela complaining that the healer's clinic kept its back room too warm for her taste, and nearly laughed, and didn't, because laughing echoed and echoes carried.

Above and behind, a voice dropped down through a grate he hadn't known was there until the sound fell through it, flattened and metallic the way voices got when they traveled pipe instead of air.

"—south ledge is clear, moving to—"

Gone. The grate's angle must have shifted, or the speaker had, and the rest drowned under the slosh of Tavo's own legs cutting through black water. He kept moving, one hand trailing the wall for a line he half remembered from the schematic, the other still cupped protectively around the collection line like it was worth more than his own skin, which at this exact moment it very nearly was.

That was the kind of thinking Bidan had drilled into him before Tavo was old enough to shave. Not clever, exactly. Thorough. Use what's already there before it uses you. The Annex's own hidden infrastructure, holding his stolen Lift steady while he worked out the rest, which struck him, even now, with his teeth starting to chatter, as the kind of joke the city would only ever tell on itself.

The tunnel bent left where the schematic said it would, the first good news he'd had in two minutes, and the water shallowed to his shins as the floor rose toward what he hoped was the old relay junction and not a dead end he'd be finding out about with his face.

Another whistle cut through from somewhere above, closer now, close enough that Tavo could make out the shape of actual words riding under the grate's metallic flattening.

"—hold position—"

He froze against the wall, water lapping at his shins, and listened with everything he had.

"—protect the cal—" the voice said, and broke apart into static-edged nonsense as whoever carried it moved out of whatever narrow angle let the sound drop through the grate at all.

Protect the what.

Tavo ran it back twice in his head, the way he'd run back Rindo's offer or Bidan's shortfall math, looking for the shape of a sentence that made sense. Protect the calibration. That was the only word that fit the broken syllable, and it sat wrong in his chest the moment he landed on it, because that wasn't language anybody used for chasing a thief out of a Sluice annex. You didn't protect a calibration from a man stealing Lift off the main draw. You protected a calibration from somebody finding out it had been changed.

He filed it next to the sealed housing he hadn't opened yet, next to the second feed line with no civic routing on any map he'd seen, next to a patrol loop that had just, tonight, stopped being a loop at all — and kept moving, because the junction was close now and the water was dropping and somewhere above him two sets of boots were still working a ledge he wasn't on anymore.

The relay junction opened into a dry chamber he hadn't scouted, hadn't known existed, round and close, with a corroded ladder bolted up one wall toward a grate he could just make out by the thin gray wash of moonlight leaking through its slats. Surface access. Not the one he'd planned, not the one Rindo's lookouts were watching for him, but a way out, and right now that was worth more than clean.

He climbed, flask secured at his hip, collection line coiled and shoved into his jacket. At the top, the grate gave with a shove and a groan that sounded far too loud for how badly he needed it to be quiet, and night air hit him — salt and tar and the ordinary rot of the low city, after twenty minutes of iron and standing water that had tried its level best to be a tomb instead of a hallway.

He hauled himself up onto wet cobble and sat there for one full second doing nothing but breathing and listening to his own pulse try to outrun itself.

Sansu's whistle sounded again, distant now, somewhere back toward the Annex's main grounds. Two short notes, and nothing after.

The flask at his hip was full. Whatever else had gone wrong tonight, that much had gone right — a complete haul, enough Lift to close most of Wela's shortfall if Bidan's math held, pulled off a valve Tavo had read correctly from thirty feet away in a scouting pass that had actually, for once, paid for itself exactly the way he'd hoped it would.

He should have felt like celebrating. Instead he sat on wet stone with his back against a drainage stack, turning three broken words over and over, trying to make them mean something smaller than what they already meant.

Protect the calibration.

Nobody built a sealed, unmapped housing off a restricted Sluice line, hid it from the official schematics, and then told their own patrols to protect its calibration from a petty thief with a small key. You protected a lie that way. You protected it from somebody important enough to notice it existed, and dangerous enough that even Sansu's own people talked around the word instead of through it.

Tavo didn't know yet what sat inside that housing, or whose name was stamped on whatever had authorized it, or why patrols guarding a leaking municipal cistern had just started speaking like they were guarding something that mattered to people a great deal higher up the chain than Captain Sansu.

What he knew was that he had a full flask of Lift riding against his hip, a bounded debt still unpaid to the Silt, and three words that didn't belong to the job he'd actually come here to do — and that the sealed housing was still down there, exactly where he'd left it, waiting for whoever came back for it next.
