The Beasts of Tarzan by Edgar Rice Burroughs audiobook.
Tarzan book 3.
In the previous novel Tarzan reclaimed his name and title as John Clayton, Lord Greystoke. In this novel he finds that proper society is just as vicious as the jungle when greedy men threaten him and his new family. Jane and her infant son Jack are kidnapped by Tarzan's enemies, Nikolas Rokoff and Alexis Paulvitch, who then trap Tarzan himself and attempt to exile him forever on a primitive island, bereft of all those dear to him. There, however, Tarzan gains new allies in the panther Sheeta and the ape Akut, together with Akut's band.
