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 or 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 a 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?
