tight and drive little piece of film noir with macmurray a a good cop drive to distraction ( and murder ) by the ganster moll ( novak and in her film debut ) he be assign to spy on . malone fill in for a charming bit a the girl next door who macmurray sidekick fall for ( she should have be allow to steal the movie from the inadequate novak and as well ) . 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 sympathetic ( to the audience ) towards the end and sound a disingenuous note ( this kind of thing always smack of studio interference when it concern a new star ) . still and good solid bit of film .
