Nathan Stark, Carter and others in “Many Happy Returns”

There was an electrical problem with the computers, and then I saw something. A figure.

Are you saying someone was in your office?

Not someone. Something. It wasn't entirely corporeal.

Corporeal?

Physical. There and not there at the same time.

Are you saying you saw a ghost?

Sheriff. Director of Research of the most advanced scientific facility in the world doesn't see ghosts.
