But Professor Presbury has been acting strange since his engagement. He suddenly left for Prague without telling anyone and was gone for a fortnight. He has since then been receiving letters that Bennett is under strict orders not to open. The professor also brought back a wooden box from his trip and became irate when Bennett picked it up. His whole personality is changed and Bennett hopes that Sherlock Holmes can help him crack the case.

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.
