There are some great moments in this film, that I still vividly remember: The arrival of the hoodwinked husband at his "welcome" party. The scenes of his brain-injured combat buddy and obviously one or two images of Veronica Lake. The end was a bit of a let-down, feeling a bit staged and contrived. I also got confused by the fact that the police guy suddenly became "in charge of it all" - it sort of became a Poirot shtick. In essence, the ending is completely useless.
I do prefer Gun for Hire to this one, although it wasn't bad or boring. Maybe the Ladd's character was just a bit more poignantly interpreted - here he is just a tad too much of a good guy, although I could easily take to his cause.
