The floorboard creaked under Lena's bare feet as she padded to the door, the city's distant hum vibrating through the thin apartment walls. She snatched the envelope, its paper cool and damp from the hallway chill, and tore it open. A glossy photo tumbled out: her own face, eyes shut, mouth slack in sleep—taken hours ago through her bedroom window.

Heart slamming against her ribs, Lena scanned the empty hall, shadows pooling like ink under flickering bulbs. No one. She slammed the door, bolted it triple-locked, and dialed her neighbor, old Mr. Hale. 'Ever seen anything weird?' she whispered into the receiver. His line crackled with static, then silence.

Dawn painted the blinds in gray stripes. Lena brewed coffee, its bitter steam curling up, masking the faint metallic tang in the air. Hale's door across the hall hung ajar—unusual for the paranoid retiree. She nudged it open. Dust motes danced in the beam from his cracked window. On the kitchen table: another envelope, addressed to her.

Inside, a key. Not hers. It fit the lockbox under Hale's sink. She pried it open, breath shallow. A tape recorder. Pressing play, her own voice emerged, tinny and wrong: 'He's watching you too.' Sweat beaded on her forehead, cold despite the rising sun.

Memories flickered—Hale's late-night mutterings about 'echoes in the walls,' his habit of staring at her door. Lena rifled his drawers: scribbled notes, dates matching her routines. Then, a photo negative: two figures in the alley below, one blurred, holding a camera.

Her phone buzzed—unknown number. She answered, pulse roaring. Breathing. Then: 'Lena? It's Hale. Whatever you do, don't trust the voice.' The line died. She spun toward the wall they shared, pressing her ear close. A faint scrape. A whisper. Her name.
