The Treasure of the Red Tribe

George East, agent of the Congo Trading Company, frees an African chieftain of a fierce Red tribe from captivity. The grateful native promises his rescuer to reveal the location of a ruby waterfall hidden deep in the jungle. But a terrible enemy is on the trail of the escapees—the sorcerer Jim Mephfin, who has the gift of hypnosis, which means the ending of this dangerous journey may be unpredictable.
