THE TORSO Part of a human torso washes up on a beach near Gothenburg, Sweden, so mutilated that its gender can only be established by DNA testing. A similar crime remains unsolved in Denmark. Detective Inspector Irene Huss is dispatched to Copenhagen to liaise with the police. A third and a fourth victim are discovered, both of them known to Huss. She fears the killer is tracking her, killing people with whom she is connected.
