King Henry is intrigued by a preacher who is arrested for heresy and speaks with him to persuade him to give up his dissension against the practices of the Catholic Church. The preacher emphasizes to him the simplicity of the Gospel, and his suffering and convictions impress a young Tower guard. The Shadow of the Tower is a historical drama that was broadcast on BBC2 in 1972. It was a prequel to the earlier serials The Six Wives of Henry VIII and Elizabeth R and featured several actors who had appeared in them (but in new roles). Consisting of thirteen episodes, it focused on the reign of Henry VII of England and the creation of the Tudor dynasty.
