Doyle, Arthur Conan: The Adventure of the Bruce-Partington Plans. V1. 9 Jan 2011
 

Sir Arthur Ignatius Conan Doyle, DL (22 May 1859 – 7 July 1930[1]) was a Scottish[2] physician and writer, most noted for his stories about the detective Sherlock Holmes, which are generally considered a major innovation in the field of crime fiction, and for the adventures of Professor Challenger. He was a prolific writer whose other works include science fiction stories, historical novels, plays and romances, poetry, and non-fiction.

The monotony of pea-soup-fog-shrouded London is broken by a sudden visit from Holmes’s brother Mycroft. He has come about some missing, secret submarine plans. Seven of the ten pages — three are still missing — were found with Arthur Cadogan West’s body. He was a young clerk in a government office at Royal Arsenal, Woolwich, whose body was found next to the Underground tracks near the Aldgate tube station, his head crushed. He had little money with him (although there appears to have been no robbery), theatre tickets, and curiously, no Underground ticket. The three missing pages by themselves could enable one of Britain’s enemies to build a Bruce-Partington submarine.
