The Locked Room’s Revenge

The office building stood like a granite tombstone against the gray November sky. I was the night security guard, a job I took for the solitude it offered. My name is Elias, and I’ve been here for six years, long enough to know every creak in the floorboards and every draft that snakes through the corridors. On this particular Saturday, the building was officially closed, and I had the place to myself until my shift ended at one in the morning. I’d already done my first patrol, a slow circuit through the echoing lobby, the silent cubicles, and the empty conference rooms. Nothing out of the ordinary, just the hum of the HVAC system and the occasional flicker of a fluorescent light.

My second patrol came at nine. I walked the same route, my footsteps tapping on the polished concrete. The kitchen was the last stop before I could head back to the guard desk and drink my lukewarm coffee. The kitchen was a relic from when the building housed a corporate cafeteria, long since abandoned but kept for the occasional event. I flicked on the lights, and they buzzed to life, revealing a sterile space of stainless steel counters and dark, yawning equipment. In the back corner stood the walk-in freezer, a massive steel door with a heavy padlock and a sliding bolt. I always checked it out of habit. The padlock, which I’d seen locked earlier, was now hanging open, its shackle dangling at the very end of the hasp. I frowned. My colleague, a woman named Rosa, had confirmed it was locked during her patrol. I figured the events manager must have popped in for something and forgotten to lock it. I clicked it shut, gave it a tug to make sure it was secure, and continued my rounds.

But something about that unlocked lock nagged at me. The building had been empty all day. I’d checked the logs. No one had signed in. The security cameras showed nothing but empty corridors. I couldn’t shake the feeling that I was being watched, that the freezer door was mocking me. I decided to take another look, just to be sure. I retraced my steps to the kitchen, the lights still humming. The padlock was open again. My blood ran cold. I hadn’t unlocked it. I hadn’t touched it since I locked it. I stood there, staring at the steel door, listening to the hum of the freezer’s compressor, which seemed louder than before. I approached cautiously and placed my hand on the cold metal. It vibrated slightly, as if something inside were moving. I pulled the heavy door open, a gust of frozen air rolling out. The shelves were lined with boxes of frozen food, but there, in the center of the floor, was a single set of footprints. Not frost or dust, but actual footprints, outlined in a dark, viscous substance that looked like dried blood. They led from the door to the back wall, where a small, rusted vent grille was barely visible. The footprints stopped at the wall, as if the person had vanished into it.

I slammed the door shut and locked the padlock with shaking hands. I backed away, my heart pounding. I radioed my supervisor, but the radio emitted only static. I called the main office on my cell, but the line was dead. I was alone, trapped in a building that seemed to be closing in on me. I decided to do a full sweep of the floor, checking every room, every closet. In the conference room, I found a memo on the table, dated a week ago, stating that the freezer had been decommissioned due to a malfunction in the locking mechanism and that no one should enter. The memo was signed by the building manager, who I knew had been on vacation for two weeks.

I returned to the kitchen, my flashlight beam cutting through the darkness. The padlock was open again. I didn’t bother locking it. I pulled the door open, and the footprints were gone. In their place was a puddle of water, and on the back wall, scrawled in what looked like frost, was a message: ‘You should have left it locked.’ I turned to run, but the freezer door slammed shut behind me, and the padlock clicked into place from the outside. I was trapped. The temperature began to drop rapidly. I pounded on the steel door, but my fists made no sound. My breath frosted in the air. I searched for a way out, but there was none. The vent was sealed. The walls were solid.

As the cold seeped into my bones, I remembered a story Rosa had told me, about a security guard who died in this building years ago, frozen to death in a walk-in freezer. They never found the body. Now I knew why. The freezer wasn’t just a piece of equipment; it was a hungry maw, a gateway for something that fed on the living. I huddled in the corner, my teeth chattering, and I heard a whisper, soft at first, then growing louder, a chorus of voices urging me to give in. The last thing I saw before darkness claimed me was the padlock, hanging open, as if inviting the next victim.
