Flamboyant television chef Dexter Paris and his identical twin brother, conservative banker Norman, are supposedly not talking to one another. But both disapprove that their uncle Clifford Paris has become engaged to young, beautiful Lisa Chambers. One of the brothers kills uncle Clifford by dropping an electric mixer into the bathtub while he is bathing, electrocuting him. The body is moved to the gym to make it seem like he had a heart attack while using an exercise bike. Clifford's lawyer, Michael Hathaway reveals to the twins that a new will exists, one which he is willing to "lose" for a price. However, Chambers, who became fearful when Columbo questioned her, also has a copy of the will, and thus she is murdered too. Unlike most Columbo episodes, this has a whodunit element which is not resolved until the end of the episode. Dabney Coleman plays Columbo's colleague, Detective Murray. Jeanette Nolan plays Mrs. Peck, a sharp-tongued, fastidious, loyal housekeeper who is appalled by the "terrible mess" Columbo makes in the house. Final clue/twist: The audience has seen one of the twin brothers commit the murder, but does not know which one. During much of the episode both twins try to convince Columbo the other is the killer. Columbo eventually establishes that two persons must have been involved in the actual murder. Due to the short time frame between the short circuit caused by the electrocution and the re-powering of the house, and due to the physical exertion required to drag the dead body out of the bathtub and prop it up on a stationary bike, he realizes the brothers must have worked together. When confronted, Norman admits to what they did, while Dexter screams at him to shut up. Directed by: Robert Butler. Story by: Jackson Gillis, Richard Levinson, William Link, Steven Bochco.
