Author of The Girl With All the Gifts Mike Carey presents the first book in his hip supernatural thriller series featuring freelance exorcist Felix Castor. 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. . .
