Peter Falk is Lieutenant Columbo, and the murderer is known to the audience from the get-go. This much we know before ever tuning in to Columbo: Caution--Murder Can Be Hazardous to Your Health. The special guest killer this time is George Hamilton, host of an America's Most Wanted-style TV show. Threatened with public revelation that he once starred in a porno film, Hamilton rubs out the blackmailer and cleverly covers his tracks. It must needs be that Hamilton's little murder will be re-enacted on his own TV show, and that Lt. Columbo will show up, rumpled raincoat and all, to ask that "one last question" at every turn. ~ Hal Erickson, Rovi
