There was no alternative. He turned to the conning-tower, and his men were sent below. The next moment the engines were at work, and the vessel submerged. Minutes later a swirl of water a quarter of a mile distant, and a great bulk rose to the surface out of the watery depths. The steel door of the conning-tower opened again, and the officer looked out. The beam of light from the war-vessel was gliding over the lolling surface of the water. It was moving towards him slowly, as though searching carefully. Again his vessel was caught in its silvery shaft. Again it held. Again the great vessel began to move towards him. With a bitter oath the officer turned back into the conning-tower and slammed to the heavy steel door. Vita and her father were standing at the water's edge. A pace or two behind them stood Von Salzinger. None of the three seemed inclined for speech. Von Hertzwohl was gazing out at the narrow opening to the open sea beyond. His thoughts were busy with the unexpected phenomenon he beheld. A searchlight was playing over the water, moving at intervals, then it would become stationary. The vessel from which it emanated was a long way out, yet its light hovered persistently, as though its whole purpose was riveted upon the definite area which lay in full view from where he stood. Vita, too, was gazing out to sea. But though the play of the lights caught and held her attention, they had no power to sway the trend of teeming thoughts which were passing through her brain. The things she beheld meant nothing to her. They could mean nothing. These were her last moments on the land she loved--the land which was the home of the man who had changed her life from a troubled and anxious existence to a dream of bliss such as she had believed impossible. She had sold herself at the price of life. Life? She had gone back again to existence a thousand times more dreadful than the worst nightmare could have conjured. Yes, her father was safe, her beloved father. All their plans would be the safer for their going. She would be free to witness, in due regularity, the progress of future seasons. She had done her duty, and her best. But oh, what a best! There were moments as she stood there waiting when she could have flung her arms out and screamed till the echoes of the cove rang again. There were moments when she could have flung herself upon the angular figure she knew and felt to be standing behind her, and impotently torn at his hated flesh. He was her master, her future arbiter, the man to whose caresses she must submit. Quite suddenly her father raised one thin, pointing hand. "The boat," he said. And Vita's thoughts were swept aside for the moment, and her comprehending gaze became fixed upon a dim object sweeping through the jaws of the cove. The darkness of the place made it impossible to distinguish its outline. It was a shadow, a mere shadow against the moving lights beyond.
