Rain slicked the pavement outside her third-floor walk-up, drumming against the fire escape like impatient fingers. Lena froze mid-step, key hovering at the lock. The door was ajar—again. Heart thudding, she nudged it wider with her boot. The apartment smelled of damp wool and something sharper, like ozone after lightning.

She swept the room with her flashlight app, beam cutting shadows from the sagging couch to the kitchenette's flickering bulb. Nothing moved. But on the fridge, pinned by her favorite magnet—a chipped lighthouse—a note in block letters: 'Check the floorboard.' Sweat beaded her neck despite the chill. She knelt, prying up the loose oak plank with trembling nails. Beneath: a Polaroid of herself sleeping, taken from inches away.

Morning light filtered gray through cracked blinds. Police came and went, chalking it up to a prank. 'Change the locks,' the officer muttered, handing back her key. Lena nodded, jaw tight, but her mind raced. Who knew about the floorboard? Only her, since moving in six months ago after the divorce. She nailed it shut, then showered scalding water over gooseflesh skin, steam fogging the mirror where faint breath marks lingered—too high for her height.

By noon, hunger gnawed, but the fridge hummed empty threats. Another note, this one taped inside the crisper: 'Heard you on the phone last night. Bad choice.' Her call to her ex—begging for closure—echoed in her ears. No one could've heard through the thin walls. Unless... She bolted to the neighbor's door, Mrs. Hale's, the widow who baked lemon bars and smiled too wide. Knocks echoed unanswered. Peering through the peephole's fish-eye: darkness, and a shadow shifting.

Dusk bled orange across rooftops as Lena paced, phone clutched like a shield. A text pinged—unknown number: 'Look up.' Heart slamming, she craned out the window. Across the alley, in the abandoned warehouse window, a silhouette waved. Her silhouette. Same red scarf, same posture slump. It pressed a paper to the glass: 'Tell them, or I will.' Tell who? The secret clawed up— the accident she drove away from, the man she'd left bleeding on that rainy road.

Night fell heavy, city hum muffled by thunder. Lena barricaded the door with her dresser, breath shallow. Scritch-scratch at the window. She whipped around—fire escape slick, but a handprint steamed the glass, palm matching hers. The door rattled. Not a knock—a key turning. Footsteps inside her head whispered her name, closer now. The floorboard creaked without her touch. What lay beneath this time?
