Lies Sleeping is the seventh instalment of the PC Peter Grant series by Ben Aaronovitch.
The Faceless Man has been murdering, sacrificing, committing fraud, and done even more heinous things, but the police and the Folly know his identity now and they’ve got him on the run. Peter Grant, now Detective Constable, is one of the key figures in the operation to bring him down once and for all. But a cornered animal is at its most dangerous, and cornered magicians even more so. The Faceless Man isn’t going down without a fight and a show, and is in the midst of completing one final mission. If he were to succeed, London will be forever changed. It’s up to Peter, and his colleagues, to stop him before he does. If they can.
