Publisher's summary
Trapped, a haunted monster waits to consume new victims. It needs help. It needs a doctor. Unfortunately, it also needs to kill whoever it meets. Thrust into immediate danger, and on the back-foot, it will take all of the Doctor's ingenuity to triumph.

Two interlinked adventures. Two Doctors. One foe.
