Female Jungle (1956)
A blonde actress is murdered across from a bar. An off-duty cop has been getting pleasantly sloshed, but becomes worried about his innocence when he finds out he was seen leaving the establishment with a blonde, but doesn’t remember. As he investigates, he interviews a columnist who was going with the actress, a caricaturist who drew the victim, the caricaturist’s wife who works at the bar, and the caricaturist’s lover, and slowly begins to put the pieces of the deadly puzzle together.
