As out of place as Agnes Morehead may have seemed in this episode considering her voice and age; I can't imaging anyone else pulling this off.  She was perfect; the age in her voice actually made her character more interesting.  Her father, a self righteous professor was also a great character.  This is a very good episode that holds you captive until the end.  Agnes Morehead was great in all of her rolls. The most memorable was Return of the Moresbeys CBS RMT and The Invaders Twilight Zone.  I like the turn of events at the end of this episode as I am sure everyone will.
