Rex Brandon #4: White Gold

Deep in Central Africa, plantation owner Randolph Meyrick stumbled across something that had hitherto been only a legend—an Elephant’s Graveyard! With a fortune in ivory at stake, Meyrick invites Rex Brandon, famous geologist and big game hunter, to partner him in a safari to the Matan Hills.
Others know of Meyrick’s discovery — unscrupulous rivals who will stop at nothing to obtain the white gold for themselves. Brandon soon finds himself caught up in a desperate contest for survival, battling unseen enemies and native perils, with agonizing death for the unwary.
