Leo closed the laptop, his heart hammering. He looked up at the wall of his own office. He didn't own a dial clock, but as he sat in the silence, he heard it—a heavy, metallic thump coming from inside the wall, followed by the sound of glass cracking.

When he clicked play, the video didn't show a person or a monster. It was a fixed shot of a dial-type wall clock in a dimly lit hallway. There was no audio, just the rhythmic, heavy movement of the second hand.

Leo watched for three minutes. Nothing changed. The second hand ticked from the twelve, around the circle, and back again. But on the fourth rotation, he noticed a glitch. The hand didn't move to the next second; it stayed on the six, vibrating violently.
