Mark Twain's The Man That Corrupted Hadleyburg

Hadleyburg, a town with the reputation of being the most honest in America, is visited one day by a mysterious man who has come to right a wrong that was once done to him by its inhabitants: too egotistical, they'd forgotten the basic rules of hospitality. His strategy is thus to strike where it hurts them most: shattering their reputation for probity... A successful adaptation of Mark Twain’s famed short story.
