tight and driven little peice of film noir with macmurray a a good cop drive to distraction ( and murder ) by the gangester moll ( novak and in her film debut and somewhat more effective than usual ) he be assign to spy on . malone fill in for a charming bit a the girl next door who macmurray sidekick fall for . typically and a mistake be make by the criminal and and they will pay for it and but theyre have fun along the way . some confusion in the script seem to have result in novak character turn somewhat sympathetic towards the end and sound a disingenuous note . still and good solid bit of film .
