There was no time for a second stroke. Before the Cimmerian could lift his blade again or spring clear, the sweep of a giant arm knocked him from the span as a fly is flicked from a wall. As he plunged downward the rush of the river was like a knell in his ears, but his twisted body fell halfway across the lower arch. He wavered there precariously for one blood-chilling instant, then his clutching fingers hooked over the farther edge, and he scrambled to safety, his sword still in his other hand. As he sprang up, he saw the monster, spurting blood hideously, rush toward the cliff-end of the bridge, obviously intending to descend the stair that connected the arches and renew the feud. At the very ledge the brute paused in mid-flight--and Conan saw it too--Muriela, with the jewel chest under her arm, stood staring wildly in the mouth of the tunnel. With a triumphant bellow the monster scooped her up under one arm, snatched the jewel chest with the other hand as she dropped it, and turning, lumbered back across the bridge. Conan cursed with passion and ran for the other side also. He doubted if he could climb the stair to the higher arch in time to catch the brute before it could plunge into the labyrinth of tunnels on the other side. But the monster was slowing, like clockwork running down. Blood gushed from that terrible gash in his breast, and he lurched drunkenly from side to side. Suddenly he stumbled, reeled and toppled sidewise--pitched headlong from the arch and hurtled downward. Girl and jewel chest fell from his nerveless hands and Muriela's scream rang terribly above the snarl of the water below. Conan was almost under the spot from which the creature had fallen. The monster struck the lower arch glancingly and shot off, but the writhing figure of the girl struck and clung, and the chest hit the edge of the span near her. One falling object struck on one side of Conan and one on the other. Either was within arm's length; for the fraction of a split second the chest teetered on the edge of the bridge, and Muriela clung by one arm, her face turned desperately toward Conan, her eyes dilated with the fear of death and her lips parted in a haunting cry of despair. Conan did not hesitate, nor did he even glance toward the chest that held the wealth of an epoch. With a quickness that would have shamed the spring of a hungry jaguar, he swooped, grasped the girl's arm just as her fingers slipped from the smooth stone, and snatched her up on the span with one explosive heave. The chest toppled on over and struck the water ninety feet below, where the body of the servant of Bît-Yakin had already vanished. A splash, a jetting flash of foam marked where the Teeth of Gwahlur disappeared for ever from the sight of the man.
