The addictive new psychological thriller from the author of The Girl on the Train, the runaway Sunday Times Number One best seller and global phenomenon. In the last days before her death, Nel called her sister. Jules didn't pick up the phone, ignoring her plea for help. Now Nel is dead. They say...
The first message sent to Tom Thorne's phone was just a picture - the blurred image of a man's face, but Thorne had seen enough dead bodies 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 bulletins for a reported death that matches the photograph. Then another picture arrives.
