Nightmare at Pendragon's Castle, the opening episode, sets up the show's whodunit format and introduces the Capra character.
Wealthy and obnoxious publisher Robert Vaughn is
done in at his mansion, and the suspect list is also
Vaughn's list of dinner guests — each has some motive for wanting him dead.
Capra is put on the case when movie star Janet
Margolin is arrested for the killing.
A powerful, sadistic publishing magnate is found slain in the courtyard of his mansion, and as legal sleuth Eddie Capra puts the pieces together he assembles a list of suspects, each of whom has a motive based on past scandals or mistreatment by the murdered man.
