One summer evening in 1999, seventeen-year-old Tone Vaterland was killed on her way home from work.The police—desperate for a quick conviction—deemed the investigation an open-and-shut case and sent her embittered ex-boyfriend, Danny Momrak, down for murder. Her family were able to grieve, her body laid to rest, and the public felt justice had been done. The streets were safe again. But twenty years later William Wisting receives an anonymous letter. It suggests the wrong man was convicted for Tone's death and the real murderer is still out there. Wisting is quickly thrown into a terrifying race against time where he must find the sender and catch the real killer before they strike again. But nothing is as it seems. As Wisting disappears further into a dark past of secrets, lies and murder, his own life is threatened. Can he find Tone's killer before it's too late?
