Algis Budrys' "Ultimate Brunette" from Playboy in Sept. 1965 is a terrifying story about a salesman who wronged a woman and kicked her out on the side of the road. Now every town he goes to he meets a brunette who falls for him, but each one eventually gets a little smarter and nastier. It may be guilt, or it may be something paranormal, divine justice for his sexist behavior. He dreads what will happen when he finally meets the one brunette who finally has enough of him and gives him what he deserves. Budrys was fiction editor of Playboy at the time. The illustration accompanying the story is also very creepy. He reprinted it as "Last Brunette" in his 1978 collection Blood and Burning, with an intro explaining the story and the illo. Perfect tale for #MeToo era.
