Perry Mason - Season 7 - Eps 20: The Case of the Frightened Fisherman
Chemist Randolph James has started a successful company to develop a new antibiotic but his former boss, Hudson Bradshaw, files suit claiming that James developed the formula while in his employ. James' wife, Natalie, then begins selling her stock to Bradshaw which would give him control of the new company. James vows to stop his wife at any cost and she turns up dead. James claims that he was fishing at the time the murder occurred but things go from awful to good grief when he can't find the fellow fisherman who can substantiate his story.
