The first message sent to Tom Thornes mobile phone was just a picture - the blurred image of a mans face but Thorne had seen enough dead bodies in his time to know that the man was no longer alive. But who was he? Who sent the photograph? And why? While the technical experts attempt to trace the sender Thorne searches the daily police bulletins for a reported death that matches the photograph. Then another picture arrives. Another dead man ... It is the identities of the murdered men which give Thorne his first clue a link to a dangerous killer hed put away years before and who is still in prison. With a chilling talent for manipulation this man has led another inmate to plot revenge on everyone he blames for his current incarceration and for the murder of his family while he was inside. Newly released this convict has no fear of the police no feelings for those he is compelled to murder. Now Tom Thorne must face one of the toughest challenges of his career knowing that there is no killer more dangerous than one who has nothing left to lose.
