A Dog's Tale and Selected Stories by Mark Twain Twain began his career writing light, humorous verse, but he became a chronicler of the vanities, hypocrisies, and murderous acts of mankind. At mid-career, he combined rich humor, sturdy narrative, and social criticism in Huckleberry Finn. He was a master of rendering colloquial speech and helped to create and popularize a distinctive American literature built on American themes and language.
