But what he doesn’t know is that he’s about to encounter something — and somebody — that nobody ever expects…Effortlessly original, endlessly inventive and hugely entertaining — step into the world of the much-loved, Number One bestselling Rivers of London series.

Peter Grant was just a probationary constable in the Metropolitan Police Service when one night, in pursuance of a murder inquiry, he tried to take a witness statement from someone who was dead but disturbingly voluble, thus bringing him to the attention of Inspector Nightingale, the last wizard in England.Now Peter is a Detective Constable and a trainee wizard, the first apprentice in fifty years and his world has become somewhat more complicated: nests of vampires in Purley, negotiating a truce between the warring god and goddess of the Thames, digging up graves in Covent Garden and there’s something festering at the heart of London, a malicious vengeful spirit that takes ordinary Londoners and twists them into grotesque mannequins to act out its drama of violence and despair. The spirit of riot and rebellion has awakened in the city and it falls to Peter to bring order out of chaos — or die trying.

Peter Grant is not just a lowly Detective Constable, he’s also apprenticed to the last wizard in Britain: policing will never be the same again!The second in the Rivers of London series of urban fantasy/police procedurals featuring Peter Grant.’When I was a kid, it was my job to change my dad’s records while he lounged around and drank tea. This is why I know my Argo from my Tempo and why, when Dr Walid called me down to the morgue to listen to a corpse, I recognised the tune it was playing as ‘Body and Soul’. Not literally playing, you understand, but something violently supernatural had happened to the victim on or around his death, something strong enough to leave its imprint on his corpse as if it were a wax cylinder recording. The former owner of the body was one Cyrus Wilkinson, part-time jazz saxophonist and full-time accountant, who dropped dead of a heart attack half an hour after finishing a gig in a Soho jazz club. He wasn’t the first.’
