Iris Vale kept her hands in the sound. She measured dust not in motes but in decibels, learned an archive by the tiny changes in a recording when humidity rose, by the way a janitor’s footstep in 1987 snapped against tiles. The Transit Annex smelled of old paper and oil and the faint copper tang of circuitry. Mismatched light bulbs hummed in the high ceiling like annoyed insects. At night, when the building emptied, the stacks became a cathedral of lost announcements. Voices slept in catalog drawers; some would not wake for months.
She had taken a secondhand key to the Annex because it fit the lock and because the city paid her the kind of wage that let her order coffee with milk. Her badge said “Archive Technician.” Her mother called her steady. Her friends called her practical. Lately they had started saying things like "obsessed" when she missed dinners to clean a reel or to cross-reference a broadcast. Iris had never meant to be remarkable. She liked the small certainties of the registers, the predictable hiss of tape.
On Monday hours she sat at a long table littered with spools and headphones. A small maintenance drone — a retro model they kept for sentimental reasons — trundled past the table with a clipped, mechanical sigh. Iris clicked through a digital index and a battered analog player at once. Most of her work was routine: label, transcribe, tag a voice to a name. She cataloged the city's public memory: lost announcements for boarded stations, cheery voices that once told commuters which car to avoid, an old mayor's trembling promise on a rainy afternoon.
She liked hands-on work. Her fingertips remembered the ridges of the original storage boxes, the way a steel clasp gave when it had been opened too often. When she listened to a track she leaned forward as if proximity mattered; she worried that distance would thin the voices and let them slip away. On the desk beside her a handwritten card listed the Annex's oddities: ripped schedules, a cassette with an unknown station tag, a cloth-wrapped microphone with a nickname — "Lumen." Iris had nicknamed the night more than once: the city under light was a different species than the city that slept.
At 2:12 a.m. a new file blinked on her screen, flagged by an algorithm the Archive's contractor had installed. The flag read ANOMALY. Iris frowned and smoothed a hand over the label. The file's timestamp came from a system that had been shut down for twenty years. She clicked play.
