Publisher's Synopsis
This is the twenty-third book in the Tarzan Series. Written from January to February 1940, the story was never published in Burroughs' lifetime. Tarzan tracks down a man who has been mistaken for him. The man is under the delusion that he is Tarzan, and he is living in a lost city inhabited by people descended from early Portuguese explorers. The plot devices of a lost city and a Tarzan "double" or impostor had been used by Burroughs in some previous Tarzan novels.
