Book excerpt: A Double Barreled Detective Story is a short story/novelette by Mark Twain (Samuel Clemens), in which Sherlock Holmes finds himself in the American west. The story contains two arcs of revenges. In the primary arc, a rich young woman is abused, humiliated and abandoned by her new husband, Jacob Fuller, whom she married against the wishes of her father. In the second arc, at a mining camp in California, Fetlock Jones, a nephew of Sherlock Holmes, kills his master Flint Buckner, a silver-miner, by blowing up his cabin. This is a satire by Twain on the mystery novel genre.
