A Double Barrelled Detective Story Mark Twain

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. The young Fuller resents her father's rejection and dismissal of him as a neer-do-well and resolves to exact his revenge by mis-treating his new bride. After his abandonment, she bears a son who she names Archy Stillman. When the child gets older, the mother discovers that he possesses an incredible ability of smell, like a bloodhound. 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.
