October, 1940. Bombs are falling on Stratford when air-raid warden Sylvia Parks sees a house with a light shining like a beacon to the enemy aircraft overhead, violating the strict blackout regulations. With no answer at the door she manages to break in, only to discover the body of a young woman - and she's been strangled with a stocking. For Detective Inspector John Jago, the scene brings back memories of the gruesome Soho Strangler, who murdered four women in the mid-1930s but has never been caught. Is there a connection? As the investigation develops, it leads him into a web of family jealousies, violence, robbery and the underworld of political terrorism.
