From The Perry Mason TV Show Book
Charles Houston thinks he’s clever; he kills his wife and makes it look like a car accident. He wants to keep her share of potential profits from an oil well. Freedom and fortune are his; that is, until a wildlife photographer shows up with the murder on film. Also, his wife's sister, Paula, keeps demanding her share of the oil profits. The situation goes from bad to worse for Charles, especially when Paula is found locked in a room with his corpse.
Watch for Barbara Bain, star of Mission: Impossible, in this episode.
SUGGESTED CORRECTION to the Summary: Paula Wallace was not found in a locked room with Charles Houston's corpse; she escaped the locked room and brought the police back with her. jfh 05Apr2023
