The Alien Guest

A greedy aristocrat is plagued by the spirit of the deceased cousin whom he murdered in order to take hold of his life and seize his wealth.

CBS Radio Mystery Theater is a radio drama series created by Himan Brown that was broadcast on CBS Radio Network affiliates from 1974 to 1982, and later in the early 2000s was repeated by the NPR satellite feed. In New York City it was not aired by the then all-news WCBS but by its originating station, WOR, which produced and announced it as simply Radio Mystery Theater.
