The Beasts of Tarzan is a novel by American writer Edgar Rice Burroughs, the third in his series of twenty-four books about the title character Tarzan.
The story begins a year after the conclusion of the previous book, Tarzan and Jane have had a son, whom they have named Jack. Tarzan has spent much time building an estate home on the Waziri lands in Uziri, Africa, but has returned to his ancestral estate in London for the rainy season.
Tarzan’s adversaries Nikolas Rokoff and Alexis Paulvitch, escape prison and kidnap the Jack. Their trap is elaborate and insidious, leading both Tarzan and Jane to be kidnapped as well. Rokoff exiles Tarzan on a jungle island, informing him that Jack will be left with a cannibal tribe to be raised as one of their own, while Jane’s fate is to be left to his imagination.
Using his jungle skill and primal intelligence, Tarzan wins the help of Sheeta, the vicious panther, a tribe of great apes led by the intelligent Akut, and a native warrior, Mugambi. With their aid, Tarzan reaches the mainland and begins a lengthy pursuit to find Jane and Jack.
