At last they reached the foot of the stair, and then they traversed a long straight corridor, with a blank wall on one hand pierced by an occasional arched doorway with a stair leading up behind it, and on the other hand another wall showing heavy barred doors at regular intervals of a few feet. Halting before one of these doors, one of the blacks produced the key that hung at his girdle, and turned it in the lock. Then, pushing open the grille, they entered with their captive. They were in a small dungeon with heavy stone walls, floor and ceiling, and in the opposite wall there was another grilled door. What lay beyond that door Conan could not tell, but he did not believe it was another corridor. The glimmering light of the torch, flickering through the bars, hinted at shadowy spaciousness and echoing depths. In one corner of the dungeon, near the door through which they had entered, a cluster of rusty chains hung from a great iron ring set in the stone. In these chains a skeleton dangled. Conan glared at it with some curiosity, noticing the state of the bare bones, most of which were splintered and broken; the skull which had fallen from the vertebrae, was crushed as if by some savage blow of tremendous force. Stolidly one of the blacks, not the one who had opened the door, removed the chains from the ring, using his key on the massive lock, and dragged the mass of rusty metal and shattered bones over to one side. Then they fastened Conan's chains to that ring, and the third black turned his key in the lock of the farther door, grunting when he had assured himself that it was properly fastened. Then they regarded Conan cryptically, slit-eyed ebony giants, the torch striking highlights from their glossy skin. He who held the key to the nearer door was moved to remark, gutturally: 'This your palace now, white dog-king! None but master and we know. All palace sleep. We keep secret. You live and die here, maybe. Like him!' He contemptuously kicked the shattered skull and sent it clattering across the stone floor. Conan did not deign to reply to the taunt, and the black, galled perhaps by his prisoner's silence, muttered a curse, stooped and spat full in the king's face. It was an unfortunate move for the black. Conan was seated on the floor, the chains about his waist; ankles and wrists locked to the ring in the wall. He could neither rise, nor move more than a yard out from the wall. But there was considerable slack in the chains that shackled his wrists, and before the bullet-shaped head could be withdrawn out of reach, the king gathered this slack in his mighty hand and smote the black on the head. The man fell like a butchered ox, and his comrades stared to see him lying with his scalp laid open, and blood oozing from his nose and ears.
