From her train compartment as she pulls into New York, heiress/whodunit buff Nikki Collins (Deanna Durbin) witnesses a murder through an office building window... and when no body is found, the authorities dismiss her as a kook. Her determined efforts to do her own sleuthing get her mistaken for a nightclub chanteuse-who also happens to be the next on the killer's hit list. Snappy mystery-comedy co-featuring Ralph Bellamy, Dan Duryea, Edward Everett Horton; Deanna gets to sing "Silent Night," "Give Me a Little Kiss, Will Ya Huh?" 94 min. Standard; Soundtrack: English.
