September 1977. Mette Misvær, a three-year-old girl, disappears without trace from the sandpit outside her home. Her tiny, close middle-class community in the tranquil suburb of Nordas is devastated, but their enquiries and the police produce nothing. Curtains twitch, suspicions are raised, but Mette is never found. Almost 25 years later, as the expiration date for the statute of limitations draws near, Mette’s mother approaches PI Varg Veum, in a last, desperate attempt to find out what happened to her daughter. As Veum starts to dig, he uncovers an intricate web of secrets, lies and shocking events that have been methodically concealed. When another brutal incident takes place, a pattern begins to emerge.
