is chiefly remembered for his creation of the amateur detective Sherlock Holmes, whose brilliant solutions to a wide variety of crimes began in A Study in Scarlet (1887) and continued through a long line of stories, collected in The Adventures of Sherlock Holmes (1892), The Memoirs of Sherlock Holmes (1894), The Hound of the Baskervilles (1902), and other works. (See Detective fiction.) His friend and foil Dr Watson, with whom he shares rooms in Baker Street, attends him throughout most of his adventures. Doyle also wrote a long series of historical and other romances, notably Micah Clarke (1889); The White Company (1891); The Exploits of Brigadier Gerard (1896), the first of many ‘Gerard’ tales; Rodney Stone (1896); and The Lost World (1912), the first of a series of stories dominated by Professor Challenger. Doyle later wrote many books on public themes. He published a History of Spiritualism (1926), a subject in which he was greatly interested.
