Fiction
 
The Mysterious Stranger, published post-humously in 1916 and belonging to Twain's "dark" period, belies the popular image of the affable American humorist. At the time this work was written, Twain had suffered a series of painful physical, economic, and emotional losses. In this antireligious tale, he denies the existence of a benign Providence, a soul, an afterlife, and even reality itself. As the Stranger in the story asserts, "nothing exists; all is a dream."
