Excellent "Columbo" finds the perceptive detective matching wits with health guru Robert Conrad who bumped off a business partner and made it look like murder. The contrast between the self-effacing but brilliant detective and the vain, arrogant icon of physical fitness is highlighted throughout. Conrad never dares Falk to knock a battery off his shoulder, but his sense of superiority makes him less sympathetic than most of Columbo's adversaries, and it's very satisfying when the usually mild-mannered detective displays a rare flash of temper during a conversation with his prey. One of the best episodes in the series.
