Numa Noite Sombria (1949)

Merle Kramer works as a stenographer for a psychiatrist. She is casually dating Karl Benson, a private eye and former cop. Merle mentions in passing that one of her boss's patients is an author with recurring dreams of murdering his wife, and she includes the fact that the wife owns valuable jewels. When the wife is found murdered in a manner identical to that of her husband's dream, the husband is naturally the prime suspect. But as the investigation of the police and insurance investigator Joe Cooper proceeds, it turns out that several people in the case, including Merle, are not what they seem.
