Morbid, karmic episode.  The anti-hero and victims are all unsympathetic.  Good use of the medium of radio since the audience could hear the ending but still ended on a question mark because we couldn't see it.  Possibly the karmic ending was used since most of the characters were unlikeable.  A more logical ending would be to note that a widow is not entitled to a mother-in-law's property--just the late husband's--and the late husband had no property since he did not legally inherit.  Roxie Roker is best known for portraying the character of Helen Willis on "The Jeffersons."  Historical thriller, no supernatural elements.
