Matlock Season 7 Episode 6

The Class

Matlock talks to a law class about his career, and the subject of 'the perfect murder' comes up. When student Eddie Price disappears after getting into it with Mark Randall, the university believes that Matlock's speech may have incited one of the students to murder. To clear his name, Matlock and Leanne decide to engage the students into an investigation into Eddie's disappearance, and soon learn that Eddie had more than they thought in common with not only Mark, but also Bobby Simpson as well -- they had all shared the same girlfriend.
