Alfred Hitchcock
A teenage girl, overjoyed when her uncle comes to visit the family in their quiet California town, slowly begins to suspect that he is the "Merry Widow" killer sought by the authorities.
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.
