Foreign Devils
Andrew Cartmel
 The story begins in China, 1800, when the Doctor and his companions arrive in their time machine, the TARDIS, at the English Trade Concession in Canton. A relic, previously thought harmless becomes active and transports his companions into the future. The Doctor tracks them in the TARDIS and materialises in England, 1900, where the descendents of an English merchant from 1800 have gathered. One of these is a man called Carnacki, who before long helps the Doctor investigate a series of strange murders in the house. When the Doctor discovers that the house and its surroundings have literally been removed from space and time, he realises that their attacker may not be all they seem.
