From The Perry Mason TV Show Book (Revised)
Investment broker Eric Pollard is apparently losing his mind. He’s done everything from violently accusing his wife Sybil of having affairs to attempting to stick up a bank. Probation office supervisor Roy Galen, a friend of Sybil’s, gets Eric a suspended sentence based upon his obvious incompetency. This only convinces Eric that Roy is Sybil’s lover. Later, Sybil is accused of mishandling $250,000; then she is murdered. When Roy is arrested for the crime, Perry, determined to find out why Eric Pollard is acting so crazy, agrees to defend the beleaguered civil servant.
