Our view
“The Devil You Know” introduces Felix Castor, a freelance London exorcist, in a dark, noir-flavoured urban fantasy. A routine job, clearing a ghost from a museum, soon has both the dead and the living after him. Some readers like the colourful characters and the modest, everyday magic. Others find it grimmer than they expected or slow to get into.

About the book
Felix Castor is a freelance exorcist, and London is his stamping ground. It may seem like a good ghostbuster can charge what he likes and enjoy a hell of a lifestyle--but there's a risk: Sooner or later he's going to take on a spirit that's too strong for him. While trying to back out of this ill-conceived career, Castor accepts a seemingly simple ghost-hunting case at a museum in the shadowy heart of London-- just to pay the bills, you understand. But what should have been a perfectly straightforward exorcism is rapidly turning into the Who Can Kill Castor First Show, with demons and ghosts all keen to claim the big prize. That's OK: Castor knows how to deal with the dead. It's the living who piss him off...
