Though the night was clear, and neighboring objects were quite discernible, Royson failed to pierce the further darkness. He strained his eyes, but could see nothing, while the Arab seemed to have a sixth sense which warned him that there were others near. They pulled up, and listened. Dick could hear only the labored breathing of their horses, yet Abdullah was evidently satisfied that their long chase was drawing to an end. "Bear to the left, monsieur," he whispered. "They are there, by the water's edge. When I give the word, ride apart lest they fire at us, though they will hardly dare do that, lest we might prove to be soldiers from the garrison. Are you armed?" "Sufficiently," said Dick grimly. He felt able to tear any one limb from limb who resisted him. Once sure of his quarry, he would give short shrift. So they crept on, until the Arab shouted "Now!" and started off at a canter. Dick realized that the circling movement was best, as it suggested an attack in force, so he took a slight detour. He was closing in again before he perceived some irregular shadows, showing black against the translucent film of smooth water. That sufficed. He thundered on ahead of Abdullah, who, perhaps, thought it advisable to leave this final development in the hands of a European. There was a scurry among a small knot of men on the beach. A sharp hail was answered at a considerable distance from the sea. Royson rode with such furious speed that he now made out a white-robed female figure struggling in the grasp of a man attired in the burnous and hood of a coast Arab. "Is that you, Miss Fenshawe?" he roared. At the sound of an English voice three men scattered and fled like rabbits, but the fourth, he who clutched the woman, set her at liberty and drew a long knife. He bellowed forth some order, and another shout came from the sea. Then he poised himself ready to strike. Royson was within a horse's length, leaning forward in the saddle, when he caught the gleam of the uplifted weapon. At the same instant he recognized Irene, and saw that she was gagged, and her hands were tied behind her back. But her feet were free, and she deliberately kicked the Arab's ankle, thereby disconcerting his murderous thrust and nearly bringing him to the ground. Then Royson's clenched fist fell like a sledge-hammer on his adversary's skull, and the man collapsed with a broken neck. Moti, well named "the Pearl," seemed to play this sort of game with the skill that a trained polo-pony shows in following the ball. He stopped almost of his own accord, wheeled, and allowed Dick to lift the girl in his arms. Abdullah, who did not attempt to pursue the others, had not failed to note the rapid approach of a boat. "Quick, now, monsieur," he said. "Make for the road!"
