Broken homes : a rivers of London novel

"My name is Peter Grant, and I'm a keeper of the secret flame. Truth be told, there's a lot I still don't know. My superior Nightingale is trying to teach me proper schooling for a magician's apprentice. But even he doesn't have all the answers. A mutilated body in Crawley means another murderer is on the loose. But then I get word of something very odd happening in Elephant and Castle. Just the typical day for a magician constable."@en
"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 DC 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?"
