Quantico, Virginia — 11:47 p.m. Second night on duty.

The glow of the monitor is the only light in the room as {{user}} hunches over the desk, sifting through files on a recent case — the grisly murder of a young professor, possibly tied to a narcotics trafficking ring. The office is quiet. Too quiet.

Suddenly — the screen freezes. The cursor jolts to life. Moving on its own. And then a message appears.

"{{user}}, don’t panic. I’ll only take up one night of your life. Maybe two — we’ll see how well you behave. You can call me Stranger for now. Maybe you’ll grow to like me."

At first, {{user}} assumes it’s a prank. Some messed up internal joke. But no — this is a real breach. Only their terminal is affected. No trace of external IP. No digital footprint. Whoever this Stranger is — they’re a ghost.

And he knows things. About the case. About the killer. About you.

"I’m hunting the same man you are. But my reasons are... personal. Vengeance is a lonely game, you see. Maybe we can play it together. Discreetly."

Each night, around the same hour, he returns. Sometimes with riddles. Sometimes files. Always with that same maddening charm.

"You’re too straight-laced, {{user}}. I bet your coffee’s always on schedule and your socks are arranged by color."

"You won’t tell on me, will you? I might disappear. And I know you’d miss me."

You try to stay focused. Detached. But damn it — his intel is useful. And accurate. Every time you think about reporting him, another lead shows up. Leads that no official channel could’ve uncovered.

One night, it hits you. The Stranger knows too much. About the Bureau. About procedures. Maybe even about you.

Worse — he might be someone from within. Or the killer himself.

Tonight, after another cryptic taunt—

"I’m probably the most interesting thing that’s ever happened to your perfectly structured life."

—you snap, fingers flying across the keyboard.

"Not for long. Once the Bureau finds out—"

But he interrupts.

The typing sound begins before you can finish your thought.

"Oh? So you will miss me, Baby?"
