Then, to my vast relief, Elizabeth ran forward, interposing herself between us. “Arnold is not to blame!” she cried. “He tried to save me!” [Illustration: It pulled me through the window-gap, and I swung far out above the Airscouts’ Fortress ] David’s hands fell to his sides. The airscout caught me by the arms and pulled me toward an elevator entrance. He forced me into the cage, the others following, and we descended a few feet, emerging into a small, bare room with walls of unsquared stone. Jones sent the elevator up and pulled the door of the shaft to. “Now you can speak. You have five minutes to explain yourself,” he said. He pulled a Ray rod from his tunic and looked at David, who nodded. CHAPTER XV THE AIRSCOUTS’ FORTRESS So I told them my story from the beginning. I spoke of the days of the Institute and Lazaroff’s experiment, of my awakening within the cylinder at the end of a century of sleep, my flight from the cellar and my discovery by Jones. I continued, telling of my first bewilderment in London, of David’s kindness which had saved my reason, described my summons that morning and the relays of spies who had led me to the Temple. When I narrated my discovery of the cylinder containing Esther’s living body I raised my eyes to David’s and perceived that I was no longer in the position of a prisoner awaiting death. David’s aspect had changed; he was trembling violently and struggling to speak. He looked fearfully at me, and Jones was hardly less moved. Then Elizabeth slipped her hand into mine. “We believe you, Arnold,” she said. Three times David attempted to speak while I was sketching briefly the remainder of my story up to the point of my encounter with Elizabeth, and each time his voice failed him. “Arnold, forgive me,” he managed to say at last. “We know that every word you have told us is true, if only you had told me before! But I see how incredible you must have thought your story. Now listen to me! “The horrors of this government will not last much longer. Plans are well under way to make an end of democracy and restore liberty to the world. You have unwittingly placed a wonderful weapon in our hands. No man can be neutral in such times. Now, Arnold, you have to make a decision which will affect not yourself only, but all of us, Britain, the Federation, and the race of men. You must choose your party.” He turned to Jones. “He must be told nothing until the time arrives,” he continued, assuming a tone of authority. “You will say nothing—nor you, Elizabeth.” He turned to me again.
