La veuve noire

This murder yarn details the career of a female killer who marries men for their money, dispatches them without leaving any clues, then lays claim to their wealthy estates and moves on in search of another goldmine. The murders come to the attention of Debra Winger, a Federal investigator, although the film doesn't explain why the government is interested in these cases. Theresa Russell, the title character, is the attractive, intelligent woman who wins the confidence of the men she targets and uses her irresistible charm to disarm her suitors. Winger soon cultivates a friendship with Russell to get closer to her and anticipate her next moves but knows that she and her quarry are on a collision course. The women play subtle cat-and-mouse games with each other until the surprise ending, which proves that a black widow can spin one web too many. Winger and Russell generated an undertow of erotic tension between them that the picture didn't explore but the movie remains a good mystery.
