As The Doctor and Romana continue to look for the scattered segments of the Key to Time, they cross Cailleach, an ancient alien criminal hiding on Earth ("The Stones of Blood"), and Grendel, a Count with his murderous eyes on the crown ("The Androids of Tara"). Note: This episode was recorded before the passing of Nicholas Courtney, hence the reason his death isn't mentioned at the top of the show. Look for Dan and Mike's thoughts about the man and his character next episode.
