Enredo

When a successful sex therapist with a best selling book and a hit TV show accidentally witnesses her business partner and lover cheating on her with an employee, she murders him. Lt. Columbo is on the case.

This time Columbo has to deal with a passion crime by a sex therapist. As usual, this completely new environment to Columbo is an opportunity for him to show off more unusual talents, as well as pit his wit against an opponent who is well versed in the psychology that he himself uses so well.—Maarten Hofman <jen@cistron.nl>

Psychologist Joan Allenby is at the acme of success in her profession: she runs her own successful sexual therapy center, hosts a popular call-in radio show, and has authored a best-selling self-help manual, "The Courtesan Complex." She is very deeply involved both professionally and personally with David Kane, her business partner, and projects herself as a focused, self-confident career woman. Unexpectedly returning to her office complex one night, she's shocked to find him and her "loyal" secretary in flagrante delicto in the therapy room talking disparagingly about her. Although severely shaken, she doesn't reveal her discovery and, taking a page from her own book, assumes the identity of a sexually aggressive and empowered high class prostitute. It is in this guise that she seduces and murders Kane, a homicide whose anomalies and contradictions are investigated by Lt. Columbo.—duke1029
