After the divorce, Emily Carter had nowhere left to go.
Her husband, Thomas, had taken everything — the house, the dog, even her sense of safety. He had the better lawyer, the bigger paycheck, and the colder heart. When the judge signed the final decree, Emily walked out of the courtroom with two suitcases and a bank account barely enough to last a month.
With no family nearby and rent prices swallowing the city, desperation drove her to do something she’d never imagined possible.
She started living in a storage unit.
It wasn’t much — just a 10×10 metal box with no windows, a sliding door, and paper-thin walls. Technically illegal, but no one patrolled after dark. She kept her cot folded in the corner, a camping lantern for light, and a small cooler filled with fruit, bottled water, and cheap sandwiches.
At night, she’d slide the door down just enough to stay hidden but leave a sliver open for air. It wasn’t comfort — it was survival.
The air smelled of dust and rust. The concrete floor leached cold through the thin mattress. Every sound — the wind rattling the metal, a truck in the distance — made her jump.
But at least it was quiet.
Until the tenth night.
The First Knock
Emily had just settled into her cot when she heard it.
Knock. Knock.
Two slow, deliberate taps from the other side of the wall.
She froze.
Her heart pounded in her throat. She held her breath and listened. Nothing. Then—again—
Knock… knock.
Followed by a faint dragging sound, like something scraping across the concrete floor.
Emily sat up, pulse racing. Maybe someone else was living in the next unit. It wasn’t unheard of — she’d read about others hiding in storage facilities, too broke to afford anything else.
Still, something about that slow, rhythmic knock made her skin crawl.
She waited, every nerve on edge. But the sound stopped as suddenly as it had started.
The next morning, she went to the front office. The manager, Marie, a woman in her fifties with nicotine-stained fingers, scrolled through the computer when Emily asked if anyone was renting the neighboring unit.
Marie shook her head.
“Nope. That one’s been empty for a month.”
Emily forced a laugh. “Just checking. Thought I heard something weird.”
“Probably rats,” Marie said without looking up.
Emily wished it were rats.
