Ben Aaronovitch has stormed the bestseller list with his superb London crime series. A unique blend of police procedural, loving detail about the greatest character of all, London, and a dash of the supernatural. 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.
