When The Fourth Tower of Inverness first aired on radio in the fall of 1972, it was released as a daily series, Monday thru Friday (65 episodes, about 7 mins each). The Daily Radio Version we are offering here differs from the CD version in that it contains all the recaps, plus previews of the next day?s episode. The CD Version does have the complete episode, but no previews, and only an occasional recap, so the story flows from one episode to the next.
