This was well done with a very good and competent cast- and William Bendix is in great form as a sleazy detective and hit man. I guess 20th Century Fox or some researcher liked the movie as well since the same story line with many similar situations was used in an episode of the 1960 TV series "Hong Kong" (also from 20thC Fox)with Rod Taylor in the same situation as Mark Stevens. Given that "Hong Kong" was a one hour show the action is crisper and Rod gets himself out of trouble in less time that Mark did in 1946. That episode of "Hong Kong" was entitled "Suitable for Framing". It also starred Julie London as his helper - although she was a singer, not a secretary. Both play very well and are certainly worth watching - assuming you can find good copies of "Hong Kong" somewhere. If you can you are in for a treat.
