If you liked this film see 'Impact' (1949) + Nora Prentiss (1947).

Starred Brian Donlevy & Ella Raines. It involved murder,twists and turns in the plot and a great ending.

Also Nora Prentiss (1947). It starred Ann Sheridan & Kent Smith. Another film that doesn't have the typical "Hollywood" ending.

Impact's in the public domain so it's on youtube:
