The Mystery of the Book. Dynak X picks up a bizarre energy transmission from Stonehenge prompting the elder Defenders to investigate. Kshin consults the book of enigma which shows him a blueprint of the ancient stone circle. In England, Flash, Lothar and the Phantom are lured inside Stonehenge by Kronos, a mysterious dark cloud, and turned into statues. Mandrake consults his old magic teacher, Theron, who informs him that Kronos is an evil monster who drove the great magician, Enigma, out of the Land of Magic, then destroyed the dimension. Kronos needs the book, which is actually the old master of magic in "book form", to materialize on Earth and destroy the planet. Our young heroes- including Kshin and the book, Enigma,- rush to the rescue; however, Rick, L.J. and jedda are also turned into statues by Kronos. Mandrake, with the help of Theron, fights off Kronos while Enigma guides Kshin into the Stonehenge circle, where he convinces Kronos to give him a blue crystal which allows Enigma to materialize and defeat the evil monster. The benevolent wizard then restores the Defenders to their natural state, before departing for the Land of Magic.
