The Doctor poses as a psychiatrist to investigate strange goings on at a mental health hospital.
Continuity
The Eighth Doctor ages about 100 years during this novel, because he travels back in time using a Sholem-Luz portal to shape events at the turn of the century, and then has to sleep in a casket in the cathedral to return to the present.
The Doctor is always referred to as 'Smith' in this story, except by Fitz and Trix. This is a reference to the classic series, when The Doctor would sometimes call himself John Smith (a very common British name).
