In the conclusion of the three-part story "Ghost Light," the Doctor (Sylvester McCoy) and Ace (Sophie Aldred) have arrived at Ace's ancestral home, Gabriel Chase, in 1883. Hoping to discover the source of Ace's nightmares, the Doctor at first concludes that the house is haunted by traditional ghosts. He quickly changes his mind when he is confronted with a spectral light, a pantry full of radioactive silverware, a Neanderthal house servant -- and a spaceship in the cellar. Written by Marc Platt, "Ghost Light, Episode 2" originally aired on October 18, 1989. ~ Hal Erickson, Rovi
