I stare at the anomaly through the monitor.

Preston Markov, someone I have worked with for over 10 years,

looks up at the camera and smiles.

That alone would have been enough to raise my suspicions.

Markov has faced off against the deadliest threats in the Foundation's history.

Each time he has come back to tell the tale,

Markov follows Foundation security protocols almost religiously.

He performed his work with stoic professionalism and without any emotion.

Markov had handpicked the team himself before they went hunting for the suspected anomaly. Markov's team had cornered the suspect in a room while other security forces waited

outside as backup. The outside security forces had reported the sounds of gunfire and

screams. A minute later, Markov came down the stairs alone and reported the suspect had gotten away.

The SCP Foundation is a unique organization.

Our records are filled with documented accounts of humans being possessed by unknown entities.

As such, clearance code phrases are standard operating procedure when one agent is separated from the team.

All three of the skeletons were a perfect match for our missing agents.

Agent Harrison clears his throat.
