Presently the latter clutched Carmichael's arm with an oath. Another boat had come into view, and they perceived that a diver in full costume was climbing into it. The motor-boat came to a stop alongside the other. It could be seen that the diver held in his hand a ball of paper. CHAPTER XIII. The diver's headpiece was being unscrewed. On either side of him stood Capperton and Carmichael, each with a loaded revolver. At length the cumbrous helmet was lifted off and the face of the diver was revealed. It was Madge! CHAPTER XIV. The motor-boat drew up beside the quay and the Foreign Secretary stepped out with the detective and his daughter. All were plainly in a joyous mood, and they smiled happily at each other. So gratified were they at their success that they quite failed to observe three men, who crept up stealthily behind them and thrust pads soaked in chloroform over their mouths. In a few seconds the struggles of the victims ceased, and their inert bodies were roughly thrust into a waiting motor. From the driver's seat Bluetherski smiled sardonically. CHAPTER XV. Madge Capperton lay in a cellar of Bluetherski's house, tightly bound and gagged. But her indomitable spirit was not yet cowed. Using the edge of a rough stone as a saw she was laboriously severing the cord which tied her wrists. At length her persistence was rewarded and the frayed ends of the rope fell apart. In fifteen seconds she stood up free. CHAPTER XVI. In another cellar, similarly shackled, the resolute detective was exerting all his mighty strength to burst his bonds. With a superhuman effort he broke the cord which held his arms, and in fifteen seconds he also was free. CHAPTER XVII. In a small room in the same house the detective's daughter methodically pressed her hand against picture after picture hung on the walls. Her face was grimly determined. At last she was successful. A large section of the wall slid back, revealing a dark opening. After a few seconds' natural hesitation the brave girl stepped through the aperture. CHAPTER XVIII. Raymond Bluetherski lay asleep. On his dressing-table rested the fatal ball of paper. Suddenly a portion of the wall moved back and Madge Capperton appeared in the opening. As noiselessly as possible she crept forward and snatched up the despatches. In a few seconds she would be safe! At that instant Bluetherski awoke, leapt out of his bed and grasped her roughly by the arm. But he had reckoned without Capperton. The commanding figure of the detective appeared in the room. He levelled a large revolver at Bluetherski, and the latter threw up his hands with a cry of baffled hate. CHAPTER XIX. In a moonlit garden Clement Carmichael was waiting impatiently. Presently Madge came to him with a radiant face and placed the lost despatches in his hands. His reputation was saved! Seizing the girl in his arms he pressed his lips to hers in a long passionate kiss. THE END. * * * * *
