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.

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.

The mother instructs her child, now sixteen, to seek out his biological father with the intent of destroying that man's peace and reputation, and hence extracting satisfaction for her.

Five years later in a 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.

In the second arc, Sherlock Holmes is depicted in employing "scientific methods" to a ridiculous degree, yet arriving at a completely wrong assessment.
