At first he considered marking it as junk and forgetting about it, but as he reached for the mouse, the title of the video caught his eye: “WeWereWatching.” There was also an indication of a date, and location. The information triggered a memory he’d suppressed, an event that had left him shaking.

The scene was dark, shot from a distance, but he knew what it was as a shock ripped through his arms and numbed his brain.
