The Adventure of the Naval Treaty

Mr. Percy Phelps, a Foreign Office employee, is desperate. An important naval treaty disappeared while he was working with it during one late night in the office. Phelps reaches out to his old schoolmate, Holmes, and asks for his help. A long and exhausting investigation begins. But it is a matter of time for the treaty to be divulged to a foreign government. Will Holmes solve the case in time? Will Phelps win his good reputation back? "The Adventure of the Naval Treaty" is a part of "The Memoirs of Sherlock Holmes". 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.
