A young nurse named Jude begins dating Rich, a handsome man who seems to be able to make everything in the world much better, especially for her. After a spate of deaths apparently caused by severe electric shocks, Jude is lead to the eccentric John Strange, a former priest turned Demon Hunter, who (uncannily) believes a demon is to blame for the recent killings. John goes on to try and convince the perplexed Jude of their existence but she doesn't believe any of it, until it transpires Rich is planning on making Jude's son his next victim...

Strange is suffering what appears to be a monumental hangover. Jude visits the Cathedral Library to conduct her own demonology research, but finds the texts locked away. The librarian refuses her request for access, saying she needs permission from the archivist, Canon Black. The likelihood of Jude being granted access seem small, especially as she overhears Black refusing Mr Mason access to the plans to Bishop Otterman's tomb. It transpires that the Bishop died in 1908, one of the last victims of Bone's Fever. Could Black fear a further outbreak of the disease if the tomb is re-opened? Or does he have a secret agenda? Past and present collide as Strange and Jude become embroiled in a spot of tomb raiding, while a mini-cab driver hears voices from his radio, and a little old lady proves less than harmless.
