DID WALTER SKINNER KILL THE STRANGE WOMAN IN HIS BED? NOT EVEN HE KNOWS, AS MULDER AND SCULLY WORK TO CLEAR HIM WHEN A MURDER INVESTIGATION TARGETS THE ASSISTANT DIRECTOR.
When Assistant Director Walter Skinner wakes up in bed next to a murdered prostitute, Mulder and Scully go to work trying to prove his innocence. But the more evidence they uncover, the worse things look for their boss. He is separating from his wife, seeing a psychiatrist for a dangerous sleep disorder, and refused to cooperate with the murder investigation. Perhaps Skinner's unstable frame of mind is linked to the dissolution of his 17 year marriage. And when his wife is run off the road and nearly killed, it looks like Skinner may be responsible. Scully tries to hold off her own suspicions even as Skinner confesses his bewilderment to Mulder. Only Mulder, convinced that Skinner has been visited by an apparition known to medieval scholars, can clear his superior of the charge. His investigation uncovers new layers of deceit in the case against Skinner, leading him to a frightened call girl, a deflated air bag, and a connection to a deeper conspiracy involving Skinner.
