The eighth book in the Tom Thorne series, from bestselling author Mark Billingham.
When a dead body is found in a North London flat, it seems like a straightforward domestic murder until a bloodstained sliver of X-ray is found clutched in the dead woman's fist - and it quickly becomes clear that this case is anything but ordinary. DI Thorne discovers that the victim's mother had herself been murdered fifteen years before by infamous serial killer Raymond Garvey. The hunt to catch Garvey was one of the biggest in the history of the Met, and ended with seven women dead.
When more bodies and more fragments of X-ray are discovered, Thorne has a macabre jigsaw to piece together until the horrifying picture finally emerges. A killer is targeting the children of Raymond Garvey's victims. Thorne must move quickly to protect those still on the murderer's list, but nothing and nobody are what they seem. Not when Thorne is dealing with one of the most twisted killers he has ever hunted...
