Arthur Conan Doyle (1859-1930) is known throughout the world as the creator of the brilliant detective Sherlock Holmes and his faithful companion Watson. Less known are his other works about the devoted science Professor Challenger, the noble Sir Nigel, and the brave foreman Gerard. And very few people know that he was also a doctor, traveler, athlete, war correspondent and an ardent promoter of spiritualism. All these manifestations of Doyle’s multifaceted nature are narrated in detail and fascinatingly by his first Russian-language biography, created by the writer Maxim Chertanov. Using a wide range of sources, the author paints a picture of the life of his hero against the background of the era, recreates his inner world, explores the mysteries of his work and the origin of the heroes of his books, loved by many generations of readers.
