Washington Post Wall Street Journal Private goes on the hunt for London's most feared killer since Jack the Ripper. For young student Hannah Shapiro, the nightmare began in Los Angeles when the owner of Private— an elite investigation firm-saved her from a horrific death. Now, after eight years, the terror follows her to London. The only man who can help is former Royal Military Police Sergeant Dan Carter, head of Private London. In London, young women's bodies are being found grotesquely mutilated. Carter's ex-wife, DI Kirsty Webb, leads the investigation into these brutal murders, which may somehow be linked to Hannah Shapiro. Working together, the two investigators are caught in a desperate race against the odds. Private may be the most advanced detection agency in the world but can they catch a predator who rivals London's most elusive killer ever?
