Elias’s heart hammered against his ribs. He stayed silent, his breath hitching as he watched the digital version of the hallway outside his room. On the screen, the figure turned its head slightly toward the camera. Even through the low resolution, Elias saw the reflection of a computer screen in the figure’s glasses.

The graininess of the footage cleared. A figure stepped into the frame from the left. It was wearing a heavy grey coat, the hood pulled low. The figure didn't try the handle or knock. It simply stood there, staring at the wood of Elias’s door. It was coming from the door

The video wasn't a video at all. When the player launched, the screen remained black, but the audio was a sharp, rhythmic ticking, like a metronome in a vacuum. After twelve seconds, a grainy image flickered into view: a locked door in a hallway Elias recognized instantly. It was the door to his own apartment, filmed from the perspective of the service elevator across the hall.

The file sat on Elias’s desktop for three months, a digital ghost named 24168.mp4. It had arrived in an encrypted email with no subject line and a sender address that was just a string of random characters. Most people would have deleted it. Elias, a data recovery specialist with a terminal case of curiosity, couldn’t let it go. He finally opened it on a rainy Tuesday at 4:00 AM.

Elias stood up, but before he could reach the door, the handle began to turn.
