It is Autumn in 1940, and London is in the grip of the Blitz. An unidentified female corpse is discovered in an alleyway in Soho. It is the fourth to be found in the last few weeks. The women--all prostitutes--have been horribly mutilated. It’s clear that in the darkness and confusion of the war-ravaged city, a "Blackout Ripper" is at work. Inspired by a true story, this is a breathtaking new novel from one of the most talented and distinctive crime writers working today.
