Aldgate station plays a role in the Sherlock Holmes story "The Adventure of the Bruce-Partington Plans" (published in the anthology "His Last Bow"). In the story, the body of a junior clerk named Cadogan West is found on the tracks outside Aldgate, with a number of stolen plans for the Bruce-Partington submarine in his pocket. It seems clear enough that "the man, dead or alive, either fell or was precipitated from a train." But why, wonders Holmes, did the dead man not have a ticket? It turns out that the body was placed on top of a train carriage "before" it reached Aldgate, via a window in a house on a cutting overlooking the Metropolitan line. Holmes realises that the body fell off the carriage roof only when the train was jolted by the dense concentration of points at Aldgate. Aldgate is also mentioned in John Creasey's 1955 detective novel "Gideon's Day". It has also appeared in two films: "Four in the Morning" (1965) starring Ann Lynn and Norman Rodway and "V for Vendetta" (2006), starring Hugo Weaving and Natalie Portman.
