A crazed serial killer who hunted girls in London. And a detective for whom the price may be too high. When a young girl is found raped and strangled on a secluded path along the Thames, suspicion first falls on the victim's former lover. But the complete lack of evidence and witnesses leads the police to a completely different idea... After the bodies of several more women killed in exactly the same way appear, it becomes clear that an obsessed serial killer is on the loose. And a bloody trail has been trailing behind him for a long time. For the young and ambitious inspector Rob Miller, this is the first serious investigation. He must prevent another attack at all costs. The detective only has a profile of the maniac and his special handwriting, with which he likes to mark his victims. There is not a minute to lose in this matter, because a new hunt has already begun.
