When we last saw Kay Hoog (rich adventurer, brave hunk), he was suffering. After narrowly escaping an ancient Incan city, Hoog looked forward to a few years of quiet living with his (amicably caught) Incan beauty, Naela. But the past hit hard. After Hoog's arch-nemesis, Lio Sha, murdered Naela on his estate, he vowed vengeance on her and her criminal organization, the Spiders. In search of the Buddha-head Diamond, he must now discover them. The head, it is thought, can reestablish Asia's global dominance.
