The two unknown passengers got aboard in the very last minute. Their baggage was not searched. And their plan consisted of some mysterious box. What do you think happened in the evening? Did Mr. Hammond try to warn the rest of the crew or he escaped with a life boat? Can all be a big misunderstanding or the American steamer will be blown up?

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.
