The Confidence-Man is an ambiguous figure who sneaks aboard a Mississippi steamboat on April Fool's Day. This stranger attempts to test the confidence of the several steamboat passengers whose interlocking stories are told as they travel down the Mississippi River toward New Orleans. The novel is written as cultural satire, allegory, and metaphysical treatise, dealing with themes of sincerity, identity, morality, religiosity, economic materialism, irony, and cynicism. Herman Melville's writing draws on his experience at sea as a common sailor, exploration of literature and philosophy, and engagement in the contradictions of American society in a period of rapid change. His best known works include Typee, a romantic account of his experiences in Polynesian life, its sequel Omoo, and the great classic Moby-Dick.
