Greenwich, south-east London. The Met's crack murder squad, AMIP, is called out by nervous CID detectives to a grim discovery. Five bodies, all young women, all ritualistically murdered and dumped on wasteland near the Dome. As each post-mortem reveals a singular, horrific signature linking the victims, officers realize that they are on the trail of that most dangerous offender: a sexual serial killer.

Detective Inspector Jack Caffery - young, driven, unshockable - finds himself facing both hostility within the force and echoes of his past in this, his first case with AMIP. Haunted by the memory of a death long ago, he employs every weapon forensic science can offer for he knows it is only a matter of time before this chaotic, sadistic killer strikes again.

In her astonishing and acclaimed debut, Mo Hayder has written a novel of frightening and raw intensity which ranks alongside the very best in the genre.
