A young woman has disappeared without a trace and her friend, a patrolman, is quite sure that she was murdered. But there is no evidence of a crime. Does the policeman himself have something to do with his girlfriend's disappearance? Borowski has no idea that the cop's neighbor, a veterinarian, has committed the seemingly perfect crime. Behind the facade of the compassionate, kind veterinarian lies a deep souldisturbed personality who does not shy away from murder. And it works in an extremely clever way. With the help of the young police candidate Sarah Brandt, Borowski gradually succeeds in seeing through the web of lies and deception. But when a second body turns up, the case takes a surprising turn and Borowski finds himself in a dangerous duel in which Sarah Brandt plays a key role.
