The Devil You Know

Felix Castor is a freelance exorcist, and London is his stomping 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.

When Castor accepts a seemingly simple ghost-hunting case at a museum in the shadowy heart of London, 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.

But that's business as usual: Castor knows how to deal with the dead. It's the living who piss him off. . .
