Charlotte "Charlie" Newton is bored with her quiet life at home with her parents and younger sister. She wishes something exciting would happen and knows exactly what they need: a visit from her sophisticated, much-traveled Uncle Charlie Oakley, her mother's younger brother. Imagine her delight when, out of the blue, they receive a telegram from Uncle Charlie announcing that he is coming to visit them for awhile. Charlie Oakley creates quite a stir and charms the ladies' club, as well as the bank President where his brother-in-law works. Young Charlie begins to notice odd behavior on his part, such as cutting out a story in the local paper about a man who marries and then murders rich widows. When two strangers appear asking questions about him, she begins to imagine the worst about her beloved Uncle Charlie.
