After World War I he returned to his home town to work for the Indianapolis Star and the Union . His most popular drama, The Killer, played on Broadway for three years. Maxwell began researching the issues surrounding Shakespearean authorship about 1908, publishing his first article on the topic in 1916. He completed the first portions of The Man Behind the Mask by 1918. Theodore Dreiser helped him in attempts to interest various publishers between 1919 and 1924, but none were successful.
