Marie Jensen (Cara Williams) was the villainess from Alfred Hitchcock Presents episode 5.17, "The Cure" (airdate January 24, 1960). She was the wife of oil explorer Jeff Jensen, but late one night, she attempted to kill Jeff while he was in bed. Jeff attributed Marie's actions to tropical fever, and he had his partner, Mike, and his servant, Luiz, take her to a head shrinker.
However, Marie is revealed to be having an affair with Mike, and her attempt to kill her husband was intentional. During their journey, the evil Marie convinced Mike to kill Luiz, believing that he is in the way of their happiness, but Luiz manages to kill both of them, and shrinks the head of the villainess.
