The Locked Flat

Wren told herself she was going to leave it alone. She lasted four days.

The thing that broke her was the humming. It came on a Tuesday at 2:40 a.m. — three notes, that same fragment of tune, clearer than ever — and Wren found herself standing on the landing in her pyjamas with her phone's flashlight on, in front of the dark green door, before she'd consciously decided to move.

Up close, the door told stories. The paint was newer than the hallway's. The lock, though — the lock was old, brass, the original. And at the base of the door frame, barely visible, the wood was scored with thin parallel grooves, like something had been dragged across the threshold many times, over years.

The door was locked. Wren didn't try to force it. She was an archivist, not a burglar; she had a healthier respect for locked doors than that.

Instead she did what she did best: she found the paper trail. Keys for the whole building would be in Mrs. Okafor's flat, and Wren was not going there. But buildings like this had other keys, other doors — service cupboards, meter rooms, a basement. And the basement door, behind the stairs, had a padlock so old it opened to a firm tug and a prayer.

The basement smelled of coal dust and damp. Wren's flashlight found the storage room for flat 5 — the one Mrs. Okafor had leased — or rather, it found where flat 5's storage should be, because the cage was empty except for a folded camp bed, a stack of plastic sheeting, and a single cardboard box, water-stained at the corners.

Inside the box: a child's drawings, decades old. A school exercise book with the name E. Okafor on the cover. And a newspaper clipping, folded small, twenty-three years old: LOCAL GIRL, 16, MISSING — third such case in the district.

Wren sat down slowly on the camp bed.

E. Okafor. Mrs. Okafor had a daughter. Had — past tense, the box said, in every folded, water-stained, twenty-three-year-old word of it.

And the girl in flat 9, Sable Reyes, had been twenty-two — the same age E. Okafor would have been, Wren calculated with cold fingers, the year she disappeared.

She took a photo of the clipping, put everything back exactly, and went upstairs to lie awake until her shift, listening to the building breathe around her like something that had been holding a secret so long the secret had become structural.
