The Adventure of the Bruce-Partington Plansaf Arthur Conan Doyle

A thick smog has fallen over London. Mycroft comes to visit his brother Sherlock Holmes, asking for his help. A ten-page secret document has gone missing and three pages have just been found... in the pocket of Arthur Cadogan West’s lifeless body. He was discovered near Aldgate tube station with his head smashed in and with only a little money, the confidential pages, and theatre tickets on him. Strangely, he had no Underground ticket. The document is a construction plan for the Bruce-Partington submarine and it is feared that the document may fall into enemy hands.
"The Adventure of the Bruce-Partington Plans" is part of "His Last Bow".
Sir Arthur Conan Doyle (1859-1930) was born in Scotland and studied medicine at the University of Edinburgh. After his studies, he worked as a ship’s surgeon on various boats. During the Second Boer War, he was an army doctor in South Africa. When he came back to the United Kingdom, he opened his own practice and started writing crime books. He is best known for his thrilling stories about the adventures of Sherlock Holmes. He published four novels and more than 50 short-stories starring the detective and Dr Watson, and they play an important role in the history of crime fiction. Other than the Sherlock Holmes series, Doyle wrote around thirty more books, in genres such as science-fiction, fantasy, historical novels, but also poetry, plays, and non-fiction.
