From The Perry Mason TV Show Book
Tom Wyatt has discovered a cure for a fatal fish disease called gill fever. It’s worth a small fortune, so much so that Wyatt’s boss, Jack Huxley, claims the formula, since it was made in his company.

Wyatt disagrees and tells his story to Perry, flying into a rage in the process, saying Huxley doesn’t have the right to live. Somebody must have heard him, because sure enough, Huxley is later poisoned and dies. Tragg drags out heavy evidence against Wyatt. But despite how it looks, Perry takes the man’s case and wins this fish story. And he gets a chance for a little tale on the side: During Perry’s investigation, Huxley’s secretary flirts with our dynamic lawyer and even invites him home to “question her.”
