"The Man That Corrupted Hadleyburg" is a satirical short story by Mark Twain. Hadleyburg, a small town renowned for its unbending honesty, offends a mysterious stranger who vows revenge. He leaves a sack of "gold" with a note claiming it belongs to whoever once gave him life-saving advice. Nineteen leading citizens, corrupted by greed, falsely claim the deed. At a public unveiling, the sack is revealed to contain lead coins, exposing the townspeople's hypocrisy and shattering the town's proud reputation. Consumed by guilt, the Richards couple falls ill and dies. Twain masterfully satirizes human vanity, hypocrisy, and the fragility of moral pride.
