 Spanish actor/Tarzan lookalike Esteban Miranda, who had been imprisoned in the village of Obebe, the cannibal, at the end of the previous novel, "Tarzan and the Golden Lion", also appears in this adventure.Burrough's view on what is a natural relationship between the sexes is neatly illustrated by a secondary narrative thread in the novel, that one about the Alali or Zertalacolols, an ape-like matriarchal people living in the thorny forests which isolate Minuni from the rest of the worlds.When the enslaved and persecuted Alali males see that Tarzan is a male too and yet stronger and more formidable than any Alali female, they go to war against the females, and by killing or maiming several of them, subjugate them.
