The massive creature - a mile from head to toe! - sleeps in the steaming jungle. Is the behemoth real, or has the golden enchantress "Z" conquered the magnificent Man Of Bronze with the hypnotic power of her superhuman mind? Doc Savage meets his mental match when he uncovers the strange lost kingdom of the deadly Amazon.
