Things had gone well, despite Tarzan feeling jealous and mistrusting towards Canler (claiming that he is a bad man that reminds him of Sabor), until Canler had revealed he was working as a double agent for the Germans of the German Empire during World War I and had come for a code machine disguised as a music box he gave to Jane for safekeeping. He then kidnapped her, but was tracked down and stopped by Tarzan assisted by RAF pilot Nigel Taylor, who had been on Canler's trail. Taylor commandeers Canler's plane and takes him back to England to stand trial.
