The abduction of five-year-old Matthew Farraday provokes national outcry and a desperate police hunt. With his face splashed over the newspapers, psychotherapist Frieda Klein is left troubled: one of her patients has been relating dreams in which he has a hunger for a child who, when described, is the spitting image of Matthew. Detective Chief Inspector Karlsson starts taking Frieda's concerns seriously when a link emerges with an unsolved abduction twenty years ago and he summons Frieda to interview the victim's sister, hoping she can stir hidden memories. Before long, Frieda is at the centre of the investigation. She must chase down the darkest paths of a psychopath's mind to find the answers to Matthew Farraday's whereabouts. And sometimes the mind is the deadliest place to lose yourself.
