The Great Fog of 1952 happened in London between 5 and 9 December 1952. During these four days, a dense smog settled on the city, causing thousands of deaths. The smog was caused by lingering fog combining with smoke from coal fires. (PROSE: Amorality Tale) It was worsened by the Fumifugium. (AUDIO: The Creeping Death)
Behind the scenes Edit
Though the name "Great Smog of London" is never used during The Creeping Death, the date in which the story is set and the Tenth Doctor's comment that the smog happening was the worst London had ever seen makes the event recognisable enough. Amorality Tale refers to the event as the "Great Fog of 1952".
