But he was dealing with one whose thews were nerved to the quickness of a jungle cat. Even as the dagger flashed in the dim light, Conan caught the dusky wrist and smashed his clenched right fist against the Stygian's jaw. The man's head went back against the stone wall with a dull crunch that told of a fractured skull. Standing for an instant above him, Conan listened intently. The cresset burned low, casting vague shadows about the door. Nothing stirred in the blackness beyond, though far away and below him, as it seemed, he caught the faint, muffled note of a gong. He stooped and dragged the body behind the great bronze door which stood wide, opened inward, and then the Cimmerian went warily but swiftly down the corridor, toward what doom he did not even try to guess. He had not gone far when he halted, baffled. The corridor split in two branches, and he had no way of knowing which the masked priests had taken. At a venture he chose the left. The floor slanted slightly downward and was worn smooth as by many feet. Here and there a dim cresset cast a faint nightmarish twilight. Conan wondered uneasily for what purpose these colossal piles had been reared, in what forgotten age. This was an ancient, ancient land. No man knew how many ages the black temples of Stygia had looked against the stars. Narrow black arches opened occasionally to right and left, but he kept to the main corridor, although a conviction that he had taken the wrong branch was growing in him. Even with their start on him, he should have overtaken the priests by this time. He was growing nervous. The silence was like a tangible thing, and yet he had a feeling that he was not alone. More than once, passing a nighted arch he seemed to feel the glare of unseen eyes fixed upon him. He paused, half minded to turn back to where the corridor had first branched. He wheeled abruptly, knife lifted, every nerve tingling. A girl stood at the mouth of a smaller tunnel, staring fixedly at him. Her ivory skin showed her to be Stygian of some ancient noble family, and like all such women she was tall, lithe, voluptuously figured, her hair a great pile of black foam, among which gleamed a sparkling ruby. But for her velvet sandals and broad jewel-crusted girdle about her supple waist she was quite nude. 'What do you here?' she demanded. To answer would betray his alien origin. He remained motionless, a grim, somber figure in the hideous mask with the plumes floating over him. His alert gaze sought the shadows behind her and found them empty. But there might be hordes of fighting-men within her call. She advanced toward him, apparently without apprehension though with suspicion. 'You are not a priest,' she said. 'You are a fighting-man. Even with that mask that is plain. There is as much difference between you and a priest as there is between a man and a woman. By Set!' she exclaimed, halting suddenly, her eyes flaring wide. 'I do not believe you are even a Stygian!'
