Later in the nineteenth century, in the United States, Mark Twain (1835–1910) grew to become American's greatest satirist: his novel "Huckleberry Finn" (1884) is set in the antebellum South, where the moral values Twain wishes to promote are completely turned on their heads. His hero, Huck, is a rather simple but goodhearted lad who is ashamed of the "sinful temptation" that leads him to help a runaway slave. In fact his conscience, warped by the distorted moral world he has grown up in, often bothers him most when he is at his best. He is prepared to do good, believing it to be wrong.
