(*)
This author wrote "The Disintegration Machine" and The Lost World, which feature the rambunctious Professor Challenger. He created "the most indispensable man in the country," and "The Woman," who marries Godfrey Norton. Another of his characters seems to fall to his death off (*) Reichenbach Falls with Professor Moriarty; that character lives at 221b Baker Street with John Watson. For 10 points, name the author of A Study in Scarlet and The Hound of the Baskervilles, who created Sherlock Holmes.
