This graphic novel basically re-tells Edgar Rice Burrough's The Return of Tarzan novel. It begins with Tarzan on a French ship in the Mid-Atlantic, where he rescues a rich woman from being attacked. Then, he arrives in Paris where he meets Paul D'Arnot. D'Arnot enlists his help, explaining that a villain named Rockoff (the Tsar of Russia's top spy) is after the gold from a list city called Opar. So Tarzan agrees to go to Africa. Along the way he befriends a tribe called the Waziri and fights some Belgians who are killing the natives. Then, once in Opar, he encounters the ape-like denizens of that city and La, the High Priestess. Plus, he's reunited with the love of his life, Jane Porter. In the last story, "A Shadow in the Golden City", La tells Tarzan that as long as she can remember, "the White Shadow" has stalked and killed the people of Opar. After he sees the dead natives Tarzan investigates--and sees that it's a four-armed ape from Mars! In the carved stones of the city it tells of Martians visited in the past--and a gate between the two worlds obviously remains open. Of course, this sets forth the events in LORDS OF MARS Volume 1....
