In 1883 the Doctor takes Ace to a house called Gabriel Chase in her home town of Perivale. Josiah Samuel Smith lives in the house but he turns out to be the evolved form of an alien who was brought to Earth in a stone spaceship which is in the basement of the house. Another member of the house is Redvers Fenn-Cooper who is out of his mind with what he has seen but Smith wants his help in killing Queen Victoria and restoring the British Empire to its former glory! This was the final 'Doctor Who' story to be made even though it was shown second in the final series. Originally transmitted: 04/10/89 - 18/10/89.
