"smart" plans to trick and rob a Pittsburg Millionaire? Will Peters find the truth about Tucker? O. Henry’s "Conscience in Art" has the answers. William Sydney Porter, better known as O. Henry, was an American writer who lived in the late 19th century. He gains wide popularity with his short stories which often take place either in New York or some small American towns. The plot twists and the surprise endings are a typical and integral part of O. Henry’s short stories. Some of his best known works are "The Gift of the Magi", "The Cop and the Anthem", "A Retrieved Reformation". His stories often deal with ordinary people and the individual aspects of life. As a result of the outstanding literature legacy that O. Henry left behind, there is an American annual award after his name, given to exceptional short stories.
