He heard the bars rattle as it tried each door in turn. Now it had reached the cell he had so recently quitted, and the door swung open as it tugged. He saw a great bulky shape limned faintly and briefly in the gray doorway, and then the thing had vanished into the dungeon. Sweat beaded Conan's face and hands. Now he knew why Tarascus had come so subtly to his door, and later had fled so swiftly. The king had unlocked his door, and, somewhere in these hellish pits, had opened a cell or cage that held some grim monstrosity. Now the thing was emerging from the cell and was again advancing up the corridor, its misshapen head close to the ground. It paid no more heed to the locked doors. It was smelling out his trail. He saw it more plainly now; the gray light limned a giant anthropomorphic body, but vaster of bulk and girth than any man. It went on two legs, though it stooped forward, and it was grayish and shaggy, its thick coat shot with silver. Its head was a grisly travesty of the human, its long arms hung nearly to the ground. Conan knew it at last--understood the meaning of those crushed and broken bones in the dungeon, and recognized the haunter of the pits. It was a gray ape, one of the grisly man-eaters from the forests that wave on the mountainous eastern shores of the Sea of Vilayet. Half mythical and altogether horrible, these apes were the goblins of Hyborian legendry, and were in reality ogres of the natural world, cannibals and murderers of the nighted forests. He knew it scented his presence, for it was coming swiftly now, rolling its barrel-like body rapidly along on its short, mighty bowed legs. He cast a quick glance up the long stair, but knew that the thing would be on his back before he could mount to the distant door. He chose to meet it face to face. Conan stepped out into the nearest square of moonlight, so as to have all the advantage of illumination that he could; for the beast, he knew, could see better than himself in the dark. Instantly the brute saw him; its great yellow tusks gleamed in the shadows, but it made no sound. Creatures of night and the silence, the gray apes of Vilayet were voiceless. But in its dim, hideous features, which were a bestial travesty of a human face, showed ghastly exultation.
