Wow--this movie had the absolute snappiest dialog of any Film Noir movie in Hollywood history. For dialog alone and Fred MacMurray's voice-overs, this must rank as one of the best Noir films of all time. The words they say are all so carefully chosen and magnificent--the writers really did their work well. And, the acting and direction are excellent as well. About the only reason I don't score it a 10 (and it sure came very close) was that, for Film Noir, there wasn't a whole lot of action or even suspense in the movie--considering you KNOW that MacMurray is making a confession so he isn't going to get away with the murder plot. Still, these are VERY minor complaints--the film is simply great. I suggest after seeing this film you watch an episode of MY THREE SONS and see the two extremes in Fred's work--the absolute apex and the absolute nadir (if you don't know what those words mean, look 'em up yourself, ya mug).
