Dick Powell is the insurance investigator. Raymond Burr is the private eye who does contract work for the insurance company. Lizabeth Scott is the girlfriend of the guy who stole a bunch of loot.
Naturally, every guy falls in love with Scott. Director Andre De Toth draws out a believably warm, human quality in her performance. Powell's character is so bored stiff at home with super-sweet wife Jane Wyatt that he chases the first dame who bats an eyelash at him. His wry delivery of some very clever lines seems fresh to this day. Burr's character is a nasty creep who probably murders h00kers in his spare time so his stalking Scott is completely believable. Once they mix in the old boyfriend, who gets sprung from jail in time for the Third Act, things get murder-y.
To be honest, I expected a different character to die. Or at least get arrested. In any event, the wrong character got the comeuppance. It may have had something to do with the Hayes Office. Would be fun to see a remake.
