The most extensive argument that the King in _Huckleberry Finn_ was based on Emperor Norton appears in the book _Norton I, Emperor of the United States_ by William Drury (Dodd, Mead, 1986). Drury partially bases his argument on the letter Twain wrote to William Dean Howells on September 3, 1880. The complete text of Drury's book (roughly formatted) is online at: http://www.emperornorton.net/norton-drury.txt Barb
