Columbo

While investigating the death of a popular actor, Columbo must outwit a cunning dentist, who has set up his wife for a murder in order to keep up his image and expensive lifestyle. It is presumed that the actor's car went over a cliff after he suffered a heart attack, although Columbo takes note that the car was set in neutral and quickly pockets a book of matches with Lydia and Wesley Corman's names embossed on it.
