A very beautiful young woman approaches Perry Mason with a strange request: her uncle Mr. Horace Shelby has given her a check for $125,000 and wants her to immediately meet Mason and together go to the bank to withdraw money. She had gone for a 3 month vacation and had come back to find this letter waiting for her. Mason and Daphne Shelby go to the bank to withdraw the amount. That's when they are shocked to find out that the account is empty. Daphne Shelby had spent her life caring for her elderly uncle. When his half-brother showed up, with his wife and a friend, they convinced the uncle that Daphne was overworked and needed a vacation. This gave them the chance to drug the uncle and have him committed. The half-brother told the court that Daphne wasn't really the old man's niece but the illegitimate daughter of his deceased housekeeper. It seems like her uncle's half brother Finchley has been appointed as the Conservator for Shelby's wealth as it was proven in court that Shelby was incompetent to handle his financial affairs. All this happened when Daphne was away. She goes home to find uncle Shelby missing and Finchley and his wife has taken over the house. They asked her to move out immediately. Penniless and homeless she goes back to Mason. Its up to Mason, his able Secretary Della Street and Mason's sharp friend, detective Paul Drake to help Daphne and find out where Horace Shelby is.
