Orient Express

The Orient Express is the name of a long-distance passenger train originally operated by the Compagnie Internationale des Wagons-Lits on Earth. The two city names most intimately associated with the Orient Express are Paris and Istanbul, the original endpoints of the service. In 1887, Sherlock Holmes and Dr. Watson were riding on the Express through Austria when they were stopped by the train of Pope Leo XIII, who commissioned Holmes to investigate the disappearance of books from the Library of St John the Beheaded in London (NA: All-Consuming Fire). The train is perhaps most famous for being the setting of a detective novel, Murder on the Orient Express, written in 1934 by Agatha Christie and inadvertently inspired by Donna Noble when she met the writer in 1926 (DW: The Unicorn and the Wasp).
