When being fit and beautiful become a health hazard.... When jet-setting playboy Jonathan Rudder's fiancee, Angela Moresby, is hacked to death in what appears to have been a sexual frenzy, Jonathan is himself the principal suspect - his maniacal moods are well known. This death is part of a pattern of horrible crimes and the police are determined to pin the whole series of gruesome murders on Jonathan. He is forced to start his own investigation, to prove his innocence - before he too becomes a victim. But as the Chief Detective-Inspector delves into Angela's murder, and another equally horrific, he slowly becomes aware of wholesale dissection. However, it is Jonathan, and his new friend, American Jennifer Brand - fiancee of another victim - who first uncover the truth about the most diabolical medical plot in history, placing their own lives in imminent danger as they do so.
