This episode was one of the biggest let downs in the history of Mystery Theater. I mean, it was just plain weak. The first 2/3 of this episode was stellar--completely original. Mystery Theater had never done a political themed episode to this point in 1974. Also, the murderer was identified at the beginning of the episode--another original concept to Mystery Theater. The story swelled and then in the 3rd act basically went no where More specifically, it just ended weakly. I would give it 5 stars for the first 2 acts and 1 star for the final act averaging out to 3 stars overall. 

On another note, you must listen to the news at the very end of this episode detailing the Watergate investigation. Great stuff from 1974.
