It seems the world is quite literally going to Hell and Jack is one of the few people that might be able to stop it. This latest adventure sees Jack getting drawn into investigating the ritual killing of children, phony mediums and a ghost interfering in his private life.
On the plus side, the book was well paced and I was desperate to know what happens next. On the negative side, the content is really heavy and disturbing. There are elements that are very similar to one of the Felix Castor books, but with a much darker edge.
