The Beasts of Tarzan is a novel written by Edgar Rice Burroughs, the third in his series of books about the title character Tarzan. Originally serialized in All-Story Cavalier magazine in 1914, the novel was first published in book form by A. C. McClurg in 1916. Not long after Tarzan claims his hereditary title of Lord Greystoke and marries Jane, their infant son, Jack, is kidnapped in London by his old Russian enemies, Nikolas Rokoff and Alexis Paulvitch. Following an anonymous call about the whereabouts of Jack, Tarzan himself falls into Rokoff's trap and is imprisoned aboard a ship carrying Jack. Jane, fearing Tarzan was entering a trap, follows him and also finds herself in Rokoff's clutches aboard the ship. Rokoff sets sail to Africa, eventually exiling Tarzan on an island near the African coast and telling Tarzan that Jack will be left with a cannibal tribe and raised as one of their own. 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 the native warrior Mugambi. With their aid, Tarzan reaches the mainland, kills Rokoff, and tracks down his wife and son. Paulvitch, the other villain, is presumed dead, but manages to escape into the jungle. Tarzan is a fictional character, an archetypal feral child raised in the African jungles by the Mangani "great apes"; he later experiences civilization only to largely reject it and return to the wild as a heroic adventurer. Created by Edgar Rice Burroughs, Tarzan first appeared in the novel Tarzan of the Apes (magazine publication 1912, book publication 1914), and then in twenty-five sequels, three authorized books by other authors, and innumerable works in other media, authorized and not. Tarzan is the son of a British lord and lady who were marooned on the Atlantic coast of Africa by mutineers. When Tarzan was only an infant, his mother died of natural causes and his father was killed by Kerchak, leader of the ape tribe by whom Tarzan was adopted. Tarzan is his ape name; his real English name is John Clayton, Earl Greystoke. Tarzan has been called one of the best-known literary characters in the world. In addition to more than two dozen books by Burroughs and a handful more by authors with the blessing of Burroughs' estate, the character has appeared in films, radio, television, comic strips, and comic books. Edgar Rice Burroughs (1875-1950) was an American author, best known for his creation of the jungle hero Tarzan and the heroic Mars adventurer John Carter, although he produced works in many genres.
