The Number One bestselling, award-winning Queen of crime fiction Val McDermid delivers a searing psychological suspense thriller. A serial killer is on the loose. His victims? Crime writers...
A murderer is at large, hunting with a bloodlust that shatters all the conventional wisdom on how serial killers operate.

Professor Fiona Cameron is a psychologist who uses computer technology to track serial offenders. She vowed never to work for the Met again after they went against her advice and screwed up an investigation as a result. But when her lover, thriller writer Kit Martin, tells her a fellow crime novelist has been murdered, Fiona can't help taking an interest.

With the killer striking again, Fiona is caught in a race against time, not only to save a life, but to bring herself redemption, both personal and professional.
