Written by Thornton Wilder, Sally Benson, and Alma Reville, the film was nominated for an Academy Award for Best Story for Gordon McDonell. Charlotte "Charlie" Newton and her parents live in very quiet Santa Rosa, California. An unexpected visit by Charles Oakley, her charming and sophisticated "Uncle Charlie", brings much excitement to her family and the small town. That excitement turns to fear as young Charlie slowly realizes her uncle is in fact a wanted serial murderer known as the "Merry Widow" killer. The fear escalates when Oakley realizes she knows his secret. In 1991, the film was selected for preservation in the United States National Film Registry by the Library of Congress, being deemed "culturally, historically, or aesthetically significant". The film was also Alfred Hitchcock's favorite of all of his films. Charlotte "Charlie" Newton is a bored teenage girl living in the idyllic town of Santa Rosa, California. She receives wonderful news: Her mother's younger brother (her eponym), Charles Oakley, is arriving for a visit. Upon his arrival, everyone is delighted, especially young Charlie. As a gesture of affection, Uncle Charlie gives his niece an emerald ring. However, she notices that it has someone else's initials engraved inside. Not long afterward, two men appear at the Newton home, trying to take Uncle Charlie's picture. Young Charlie guesses they are undercover police detectives. One of them explains her uncle is one of two suspects who may be the "Merry Widow Murderer". Charlie refuses to believe it at first, but learns that the initials engraved inside the ring he gave her match those of one of the murdered women. She then notices Uncle Charlie begin to act strangely. During dinner one night, Uncle Charlie lets his guard down and reveals his hatred of rich widows. He describes them as "fat, wheezing animals". Horrified, young Charlie runs out of the room.
