Fra Rafael saw strange things, impossible things. Then there was the mystery of the seven young virginal girls of Huascan. . . . The life of an anthropologist is no doubt filled much of the time with the monotonous routine of carefully assembling powdery relics of ancient races and civilizations. But White"s lone Peruvian odyssey was most unusual. . . . "Three months ago it began," he said, "after the earthquake. A native girl disappeared. She was seen going into the mountains, toward Huascan along the Pass, and she did not come back. I sent men out to find her. They went up the Pass, found the fog grew thicker and thicker until they were blind and could see nothing. Fear came to them and they fled back down the mountain. A week later another girl vanished. We found her footprints."
