Face in the Abyss — A. Merritt

Face of Stony Evil

High in the Andes, in a cavern of unearthly jewels, Nicholas Graydon confronts the Dark Lord of a prehistoric civilization. His colossal stone face beckons from across the chasm. The eyes promise wealth and power, but deliver death. Just as the Lord of Evil is about to claim his victim, the voluptuous Snake Woman breaks the satanic spell, saving Graydon from the abyss--saving him for the battle to come.
