Alfred Hitchcock Presents

A Body Heat-type story with series regular Robert Horton well cast as a gigolo husband who becomes smitten with a college girl and - inspired by a remark she casually makes during one of their assignations - plots the "accidental" drowning of his wife. Needless to say, there is a twist in the tale, and you might be able to guess it if you've seen enough melodramas of this type. It's well done, though, with Horton's dissolute air being very convincing and Anne Francis giving just the right number of hints that the girl might be more knowing - and more dangerous - than she seems.
