Owen Marshall, Counselor at Law S03E11 - The Prowler

Mistaking her husband to be a prowler, Kit Howell shoots him and is charged with murder after evidence indicates she may have learned of his romantic affair with a nightclub singer. After Kit tells her husband she has heard prowlers around the house for several nights, he advises her to get a gun. Then, one night, she shoots at a shadowy figure outside her house — only to find she has killed her husband, who was coming home from his nightclub. The District Attorney learns that the husband was having an affair with a club singer, Stephanie Marks, and charges the wife with murder. Kit's brother, Tom Dayton, enlists Owen Marshall to defend her.
