火星のプリンセス
During 1912 Burroughs had been working on "Tarzan of the Apes", which he finished in June of that year. By 20 September 1912 Burroughs had almost completed the sequel to "A Princess of Mars", which was entitled "The Gods of Mars". It was submitted on October 2, 1912. Metcalf had suggested killing off Dejah Thoris in the story, but Burroughs admitted to be unable to do so. Although readers had already complained about the suspense created at the end of "A Princess of Mars", Burroughs once again, produced a story with a cliff hanger ending. The tale was advertised in the December 1912 issue of "All-Story "magazine.
