The screen debut of Mike Hammer 'force of nature' and self-appointed judge, jury and executioner. Biff Elliott had an apt name to portray a detective who tends to punch in the mouth first and asks questions later. He does talk like a man whom has been hit over the head on numerous occasions but is totally outclassed by his co-star Peggie Castle, sensational as the duplicitous shrink Charlotte Manning. The narrative seems to consist almost entirely of scenes of vicious beatings-up and murders, and as in so many other movies of its type, the hero can take any amount of punches to the face and emerge unscathed. I might have found it all rather tiresome had the film been more efficiently constructed, but the generous amount of ludicrous dialogue and the generally ham-fisted approach made it almost perversely entertaining. I was amused by good old Elisha Cook Jr. and his queen bee, though this inadvertently pointed Hammer in the right direction. The finale, with the now desperate Charlotte's attempted seduction of Hammer, is unforgettable.
