Matlock - Season 1 Episode 15
The Rat Pack

When Beverly Hills cookie entrepreneur Adam Gardners girlfriend is found dead in his hot tub, the case against him looks bleak, especially when an eye witness points the finger at him. After his corporate lawyers advise him to plead guilty, Gardner hires Ben Matlock to defend him. While Matlock believes in his clients innocence, the more he learns about the victim, the greater the motive his client has, especially once love letters turn up that were exchanged between the victim and Josh Sinclair, Adams supposed best friend.
