Edgar Rice Burroughs 
The Beasts of Tarzan 

As the rich Lord Greystoke, Tarzan becomes the target of grifters and criminals. They kidnap his son Jack and his wife, Meriem, and strand Tarzan on a desert island. With the aid of the vicious panther Sheeta and the great ape Akut, Tarzan escapes. He and his new companions reach the mainland and begin hunting down the kidnappers. Tarzan intends to have such vengeance as only a human beast of the jungle could imagine. A vengeance that would chill the blood of a more civilized man.
