From The Perry Mason TV Show Book
Ex-baseball player Herbie Cornwall is striking out at trying to make a living selling arch supports. His wife Millie is a little more successful. She’s a very popular secretary for a prominent businessman. She’s so popular, she's playing around with most of the executives in her office.

When Herbie visits his wife’s office and catches her with one of her lovers, they argue, then Herbie picks up his briefcase and leaves. Later, he finds that it’s the wrong briefcase; this case contains $72,000. Herbie suspects his wife is in on an embezzlement scheme and after a fire at her office destroys most of the accounting records, he’s convinced. But before he can turn his wife in to the police, someone punches her ticket. Herbie is charged and Perry must come through in the clutch and get the ex-big leaguer off.
