A distraught Nellie Conway seeks Perry Mason's assistance when she thinks her employer, Newton Bain, is trying to kill his invalid wife. She is certain that he's a killer and has taken some of the pills to prove that they're poison. Mason finds it all far-fetched and his doubts are confirmed when the lab reports show the pills to be simple aspirin. When Bain and his stepbrother-in-law James Douglas set up a sting of sorts to show that Conway was stealing jewelry, Mason appears as her attorney at the request of Mary Douglas, Mrs. Bain's stepsister, who arrived from Hawaii to ensure justice is done. Mary visits Mason with a holographic will written by Elizabeth Bain leaving the bulk of her estate to Mary. However, Mason tells Mary that a missing period could cause problems. His dealings with this family aren't done when Mary is accused of murdering Elizabeth. It's left to Mason to solve the puzzle and identify the killer. Written by
