In this novel, the protagonist Bob Howard, an agent for the intelligence agency known as the Laundry, is tasked with investigating American televangelist Raymond Schiller, who seeks to gain influence in Britain. Bob finds out that Schiller, who preaches a quiverfull prosperity gospel, is serving a supremely dangerous supernatural entity and trying to bring about the end of the world. The book introduces new allies for Bob: Persephone Hazard, a freelancing witch and secret agent, and Peter Wilson, a vicar and expert in biblical apocrypha. According to Stross, while the first three books in the series were written in the style of Len Deighton, Ian Fleming and Anthony Price, respectively, the fourth installment is written in the style of a Peter O'Donnell (Modesty Blaise) novel. For future installments, Stross feels that "the series has acquired an identity and feel of its own", and does not intend to continue the pastiche motif.
