Wisting is back with his most gripping case yet. In 1999, seventeen-year-old Tone Vaterland was killed on her way home from work. Desperate for a conviction the police deemed the investigation an open-and-shut case and sent her spurned boyfriend, Danny Momrak, down for murder. But twenty years later Detective William Wisting receives a puzzling letter. It suggests the wrong man was convicted for Tone's death and the real murderer is still out there, and could kill again. . . Praise for Jorn Lier Horst
