When 5-year-old Matthew goes missing, an outcry erupts in London. His picture appears in the newspapers, and psychotherapist Frieda Klein cannot believe it: Matthew looks exactly like the dream child of a desperate childless patient of hers. Is this man a brutal psychopath? Why didn’t she notice this as a therapist before? Together with Inspector Karlsson, Frieda uncovers parallels to the disappearance of a girl over twenty years ago. She gets closer to the kidnapper, but it’s a race against time.
