Rivers of London : The First Rivers of London novel

My name is Peter Grant and until January I was just probationary constable in that mighty army for justice known to all right-thinking people as the Metropolitan Police Service (and as the Filth to everybody else). My only concerns in life were how to avoid a transfer to the Case Progression Unit - we do paperwork so real coppers don't have to - and finding a way to climb into the panties of the outrageously perky WPC Leslie May.

Now I'm a Detective Constable and a trainee wizard, the first apprentice in fifty years, and my world has become somewhat more complicated: nests of vampires in Purley, negotiating a truce between the warring god and goddess of the Thames, and digging up graves in Covent Garden... and there's something festering at the heart of the city I love, a malicious vengeful spirit that takes ordinary Londoners and twists them into grotesque mannequins to act out its drama of violence and despair.
