Once again, the terrifying cry rang out. The Doctor quickened his pace along the gloomy tunnels from the castle. All of a sudden, through the darkness lumbered the mighty Aggedor, Royal Beast and Protector of the Kingdom of Peladon! The Doctor fumbled in his pocket. Would these devices work? As he qualified the spinning mirror on the eyes of Aggedor, the terrible claws came closer and closer… What’s the trick behind the killings on the Planet of Peladon? Is Aggedor searching for revenge as the Ruler of Peladon wants his kingdom to become member of the Galactic Federation? Will the physician escape the claws of Aggedor and discover the reality? David Troughton reads Brian Hayles’ complete and unabridged novelisation, first published by Target Books in 1974.
