The Narrow Margin (1952)

This is an excellent B noir movie. It is about a witness protection effort by Charles McGraw, who thinks Marie Windsor is the mob widow he is protecting, when it turns out she is a policewoman plant. Jacqueline White turns out to be the real widow. This is a tense, well-done movie that depends on acting and plot rather than special effects, and is basically confined to a train on which all the principals are traveling. The budget may be B movie level, but everything else is first class. McGraw gives a sterling performance as a tough but human cop.
