The third book in the Shadow Police series from Dr Who writer Paul Cornell "An irresistible blend of guns, gangsters, cops and monsters" Ben Aaronovitch The ghost of Sherlock Holmes is dead, but who will solve his murder? The Great Detective's ghost has walked London's streets for an age, given shape by people's memories. Now someone's put a ceremonial dagger through his chest. But what's the motive? And who - or what - could kill a ghost? When policing London's supernatural underworld, eliminating the impossible is not an option. DI James Quill and his detectives have learnt this the hard way. Gifted with the Sight, they'll pursue a criminal genius - who'll lure them into a Sherlockian maze of clues and evidence. The team also have their own demons to fight. They've been to Hell and back (literally) but now the unit is falling apart . . . PRAISE FOR THE SERIES "The Shadow Police series is the quintessential British contemporary fantasy, full of grit and magic and wonderful things. Paul Cornell is a national treasure" Adam Christopher "Start this book early in the day people, because you ain't going to get no sleep until it's done" Ben Aaronovitch on London Falling "I think it is absolutely magnificent. I loved it ... I'm not sure I've been that gripped by a novel in ... well, decades" Russell T. Davies on London Falling "A much grittier vision of a gothic, fantasy London, well balanced between its depiction of the city's criminal underworld and a horrifying fantasy reality that for most of the novel lurks just at the edges of sight." Guardian "Realistic banter, original twists" Daily Telegraph "Pacy, smart and revels in London mythology. ... crikey it's good fun" Scotland on Sunday
