I say, You're Not the Duke Of Wellington Are You?

    In the episode The Girl Who Was Death, No.6 tells three children a fairy tale, and puts No.2 in the role of Napoleon Bonaparte. When No.6 as Mister X is captured by Napoleon and his daughter, and guesses that the Lighthouse is the rocket, Napoleon replies I say, you're not the Duke of Wellington are you? 
    As it happens, the book Webster's Directory of Proper Names the address of Number One, London is referred to as the old postal address of Apsley House, at Hyde Park Corner - the first Duke of Wellington's home.
   A curious point, nothing more.   Be seeing you
