It's an alluring title, to be sure, but faithful Lt. Columbo (Peter Falk) does not stray from his never-seen wife in Columbo: Sex and the Married Detective. Lindsay Crouse guest stars as Dr. Joan Allenby, a radio personality billed as "Sex Therapist of the Airwaves". The doctor finds she must counsel herself when her personal assistant ends up in bed with Allenby's business manager/lover. The scorned lady murders the errant beau and tries to pin the blame on her assistant. Lt. Columbo smells a beautiful rat, and spends the rest of the 2-hour TV film dogging Dr. Allenby's trail. Sex and the Married Detective was originally telecast on the omnibus weekly series The ABC Monday Mystery Movie. ~ Hal Erickson, Rovi
