Sir Arthur Ignatius Conan Doyle (22 May 1859 – 7 July 1930) was a Scottish writer and physician, most noted for his fictional stories about the detective Sherlock Holmes, which are generally considered milestones in the field of crime fiction. “The Tragedy of the Korosko” (1898) is a novel by Sir Arthur Conan Doyle. It was serialised a year earlier in The Strand magazine between May and December 1897. It was later adapted into a play Fires of Fate by Doyle. The play was in turn twice adapted into film, a 1923 silent film and a 1932 talkie. A group of European tourists are enjoying their trip to Egypt in the year 1895.
