I believe in the original 1930s radio show this story is based on, there was a reason given for the natives speaking English. It’s been a few years since I last listened to it, so I’m not sure I’m correct.
That plot element is from Tarzan’s Quest, but I think the story is an adaptation of a 39-part radio serial—“Tarzan and the Fires of Tohr”—broadcast in 1936. At least the characters introduced yesterday seemed to match up with them. The story that finished last week was a direct adaptation of another radio serial from the 1930s—“Tarzan and the Diamond of Asher.”
