O. Henry (Greensboro, 1862 - New York, 1910). Pseudonym of William Sidney Porter. American narrator, very popular for his humorous stories and surprising endings, which along with EA Poe, B. Harte and M. Twain is considered the founder of the proverbial American short story. As if it were one of his stories, in 1896 He received a subpoena to appear before a court for stealing a small sum from an Austin bank in which he had been employed. He fled and on his return was three years in prison. In 1902 he moved to New York, where he wrote some of his best books of stories, such as The Four Million, whose stories are collected in the book we now publish. He describes the ordinary people of New York through the irony, mockery and realism that made him famous, as well as the fortunate use of popular language.
