Book 4 in the Rivers of London series, from Sunday Times Number One bestselling author Ben Aaronovitch.

A mutilated body in Crawley. Another killer on the loose. The prime suspect is one Robert Weil - an associate of the twisted magician known as the Faceless Man? Or just a common garden serial killer?

Before PC Peter Grant can get his head round the case, a town planner going under a tube train and a stolen grimoire are adding to his case-load. So far so London.

But then Peter gets word of something very odd happening in Elephant and Castle, on an housing estate designed by a nutter, built by charlatans and inhabited by the truly desperate. Is there a connection? And if there is, why oh why did it have to be South of the River?
