In the conclusion of the four-part story "The Hand of Fear," the Doctor (Tom Baker) and Sarah (Elizabeth Sladen) transport the newly regenerated Eldrad (Judith Paris) to her home planet of Kastria. Upon arrival, Eldrad reveals that "she" is really a "he" (Stephen Thorne), determined to revive his long-dead race and conquer both Kastria and the Earth. But things don't quite turn out as planned -- not for Eldrad, not even for the Doctor. This episode represented the final regular series appearance of Elisabeth Sladen as Sarah, though she returned briefly in two future Doctor Who specials in 1983 and 1993. Written by Bob Baker and Dave Martin, "The Hand of Fear, Episode 3" originally aired on October 16, 1976. ~ Hal Erickson, Rovi
