For him there was little more to do, and the time was very near when he could retire from the strife, and watch in peace and confidence the reaping of the harvest of ruin and desolation that his hands had sown. Henceforth, the central figure in the world-revolution must be the young English engineer, whose genius had brought him forth out of his obscurity to take command of the subjugated powers of the air, and to arbitrate the destinies of the world. This was why he was sitting here, in the long twilight of the June evening, talking so earnestly with the man who, under the spell of his mysterious power and master-will, had been his second self in completing the work that he had designed, and had thought and spoken and acted as he had inspired him against all the traditions of his race and station, in that strange double life that he had lived, in each portion of which he had been unconscious of all that he had been and had done in the other. The time had now come to draw aside the veil which had so far divided these two lives from each other, to show him each as it was in very truth, and to leave him free to deliberately choose between them. Natas had been speaking without any interruption from Tremayne for nearly an hour, drawing the parallel of the two lives before him with absolute fidelity, neither omitting nor justifying anything, and his wondering hearer had listened to him in silence, unable to speak for the crowding emotions which were swarming through his brain. At length Natas concluded by saying-- "And now, Alan Tremayne, I have shown you faithfully the two paths which you have trodden since first I had need of you. So far you have been as clay in the hands of the potter. Now the spell is removed, and you are free to choose which of them you will follow to the end,--that of the English gentleman of fortune and high position, whose country is on the brink of a war that will tax her vast resources to the utmost, and may end in her ruin; or that of the visible and controlling head of the only organisation which can at the supreme moment be the arbiter of peace or war, order or anarchy, and which alone, if any earthly power can, will evolve order out of chaos, and bring peace on earth at last." As Natas ceased, Tremayne passed his hand slowly over his eyes and brows, as though to clear away the mists which obscured his mental vision. Then he rose from his chair, and paced the floor with quick, uneven strides for several minutes. At length he replied, speaking as one might who was just waking from some evil dream-- "You have made a conspirator and a murderer of me. How is it possible that, knowing this, I can again become what I was before your infernal influence was cast about me?"
