Ghost hunter James McAllister asks for Jeff's help, having been hired by wealthy American Kim Wentworth to see if her home, Crake Castle, is haunted. McAllister is killed and it looks as if Kim's husband is the murderer, trying to frighten Kim away so that he can marry girlfriend Laura but it would seem that the butler did it and the butler and Kim are the killers, anxious to run off together. Jeff is their prisoner but fortunately Marty has found a local lady who can see and hear him - in order for him to effect a rescue.
