Although Andrew Sarris italicized it in the list of Boetticher's films in The American Cinema (meaning he recognized it as one of the more notable films on the list), I've never run across any critical comment on this film. Nevertheless, it's a real discovery-- imagine Cape Fear with Wally Cox in the Mitchum role and you get some idea. Corey (who usually played stiff bureaucrats and cops himself) gets the role of his life as a mild-mannered clerk turned crook who becomes unhinged and escapes with the plan to kill the cop who sent him up. What's creepy about him is that, like Norman Bates, he never even raises his voice-- and like Norman Bates, eventually he winds up in a dress (oh, it seems logical enough as a disguise, but it introduces an unmistakable air of sexual confusion and perversity into the violent climax that catapults the film into Fullerian ranks of psychosexual luridness). And if you want to know what Brian dePalma's been trying to do all these years with movies like Blow Out and Snake Eyes, just watch how effortlessly Boetticher plays out the climax over walkie-talkies (a sequence to rival Touch of Evil).
