The Logbook's Last Page

The linen closet smelled the way it always did at this hour — starch and lye rising off the folded stacks, and under that, the sour damp of yesterday's wash sacks nobody had hauled to the dryer yet. Pima breathed through her mouth until the clove-resin smell of the key in her apron pocket cut through it, sharp as a struck match. Four shifts left before the hydraulic lock sealed the whole building shut for the season. She had maybe forty minutes before her rest period ended and someone came looking.

She knelt on the cold tile between two shelving units, out of sight of the door, and laid out everything she had.

Jala's note first, the ration chit gone soft at the corners from two days in her pocket, his cramped pencil route snaking under the south wing. Then her own duct diagram, penciled from Tano's shorthand numbers, seam widths marked in his measurements translated into hers. Last, the logbook, open to the page with her name on it, the one she'd found last rest period and still couldn't read without her stomach dropping a half inch.

She made herself look past the name this time, to the facing page, the last one with any ink on it. There, in the same cramped hand, was a compass rose scratched into the margin, and beside it a single structural term she recognized from her second-year drafting course: bearing wall, north-lateral.

"All right," she said, to no one. "Where's your north-lateral wall, then."

Jala's route ended at the three short strokes of his rung-stair, the word chute penciled beside them with an arrow. She'd assumed that meant the laundry chute on the ground floor, the one she passed twice a shift without thinking about it. She overlaid her duct diagram against his sketch, matching the chute's mouth — six inches wide, she'd measured it herself hauling sheets through it a dozen times — against the scale he'd used for the service crawl beyond.

It didn't line up. His crawl ran eleven feet from the chute mouth before the next turn. Her diagram put the nearest duct joint at nine feet. A two-foot gap that shouldn't exist if both maps described the same wall.

She sat back on her heels and let herself feel the disappointment for exactly one breath. Wrong wall. Tempting, because it was the first match she'd found, and cheap, because she wanted it to be true. She'd learned that lesson at Lanu the hard way, failing a practicum because she'd trusted the first reading that fit instead of the one that held up.

She measured again, this time counting the seam widths in the logbook's numbers against the chute's known six inches as her fixed point, the one measurement she could verify with her own body instead of trusting either man's memory. Two joints down from where she'd first tried, not up. The duct diagram's nine feet became eleven feet the moment she corrected which direction she'd been counting.

Eleven feet. The same as Jala's crawl.

"There you are," she murmured.

The seam sat behind the laundry chute's housing, a panel she'd have sworn was solid iron if she hadn't spent three nights learning to read the building by its sounds instead of its face. She checked it against the compass rose one more time. North-lateral. The bearing wall behind the chute, not the chute itself. A second stairwell, walled off and forgotten, sitting eleven feet from a door she walked past on every round.

It was almost funny, in the dry way things got funny at four in the morning. An orderly dodging inspections a decade back and a theoretical prodigy grafting the dying into the building's bones had never, as far as she knew, compared notes, and they'd landed on the exact same wall as the one place in Kaba worth lying about.

She turned back to the logbook to be sure, running her finger down the last few lines below the compass rose. Most of it was Tano's clinical shorthand, clean and cold. But the final line broke from it, plainer than anything else on the page, like he'd stopped writing for the record and started writing for whoever found this after him.

The shift lock seals the doors. It does not seal what's growing behind them. Don't mistake the countdown for a wall.

She read it twice. The hydraulic bolts everyone treated like the building's one hard rule — the thing that made Kaba survivable, the thing Sari cited like scripture — Tano was telling her, flatly, that it wouldn't hold anything he cared about keeping. Four shifts wasn't a deadline for him. It might not be a deadline at all.

Somewhere above her, a cart wheel squeaked against tile, once, and stopped. Pima went still, logbook flat against her knees, listening past her own pulse for footsteps. None came. A cart left somewhere, forgotten, or Sari doing rounds two floors up where the sound carried strangely through the vents. She counted to twenty anyway before she let her shoulders down.

She gathered the three pages into a fold of clean linen and went to look at the chute itself, just to confirm the panel by eye before she put everything away. The service alcove behind the housing was close and windowless, lit by the one bulb over the laundry scale, and she'd never had a reason to crouch down here before. She did now.

Dust lay thick and undisturbed along most of the floor, the kind that settled over weeks where nobody swept. Except along the base of the panel. There, pressed into the gray film, ran a line of boot prints — not scuffed, not smeared, but whole and clean-edged, heel to toe, the way a print looks when the dust is fresh and nobody's walked back over it since.

She crouched closer. The tread was wide, ribbed in a herringbone pattern she didn't recognize from any boot in the supply room, and the stride between prints was longer than her own by a hand's width. Too large for Jala's boots, which she'd watched him lace a dozen times. Wrong shape entirely for hers.

Someone had already found this wall. Someone had already stood exactly where she was crouching now, close enough to touch the same cold iron, and gone on through without leaving a name.

Pima did not move for a long moment, the logbook's last line still sitting behind her eyes — don't mistake the countdown for a wall — while she looked at the prints leading toward the panel and did not find a single one leading back.
