From The Perry Mason TV Show Book (Revised)
Chemist Randolph James has started a successful business to develop a new antibiotic. But when his former boss, Hudson Bradshaw, files suit claiming James developed the formula while working for him, itís only the beginning of Jamesís problems.

His wife, Natalie, is selling her stock to Bradshaw, which will give the ex-boss control of Jamesís new company. There are also whispers that Natalie is having an affair with Bradshaw. Furious, James vows to stop his wife at any cost.

Itís apparently not an empty threat, as Natalie soon turns up dead. The police say James did it. James claims that he was fishing at the time of the murder. But when he canít locate the fisherman who can back up his story, he locates Perry instead.
