Murder Is My Beat (1955) on Netflix

Plot summary

Fred Deane is found dead in Los Angeles, his face and hands burned past recognition. The landlady who discovered the body suggests that Deane's girlfriend, nightclub singer Eden Lane, had a hand in it. Detective Ray Patrick questions Eden's roommate, photographer Patsy Flint, who tries to obstruct him. Searching their apartment, he learns Eden has taken a bus north; he traces her to Deane's mountain lodge, where a snowstorm traps the two of them overnight. Eden admits she struck Deane with a figurine in an argument and left before he came to. A quick trial convicts her. Ray is assigned to take her to prison, and on the train, at a brief stop, she sees Deane standing on the platform. Convinced she is innocent, Ray jumps off the train with her.
