This was another of those restless nights when his brain went on turning like a machine whose governor had failed. He knew better than to woo sleep any further, and reluctantly climbed out of bed. Throwing on his dressing-gown, he strolled out on to the roof garden of his modest flat. There was not one of his direct subordinates who did not possess much more luxurious quarters, but this place was ample for Stormgren's needs. He had reached the position where neither personal possessions nor official ceremony could add anything to his stature. The night was warm, almost oppressive, but the sky was clear and a brilliant moon hung low in the south-west. Ten kilometres away, the lights of New York glowed on the skyline like a dawn frozen in the act of breaking.

Stormgren raised his eyes above the sleeping city, climbing again the heights that he alone of living men had scaled. Far away though it was, he could see the hull of Karellen's ship glinting in the moonlight. He wondered what the Supervisor was doing, for he did not believe that the Overlords ever slept. High above, a meteor thrust its shining spear through the dome of the sky. The luminous trail glowed faintly for a while; then it died away, leaving only the stars. The reminder was brutal: in a hundred years, Karellen would still be leading mankind towards the goal that he alone could see, but four months from now another man would be Secretary-General. That in itself Stormgren was far from minding—but it meant that little time was left if he ever hoped to learn what lay behind that thickened screen.

Only in the last few days had he dared to admit that the Overlords' secretiveness was beginning to obsess him. Until recently, his faith in Karellen had kept him free from doubts; but now, he thought a little wryly, the protests of the Freedom League were beginning to have their effect upon him. It was true that the propaganda about Man's enslavement was no more than propaganda. Few people seriously believed it, or really wished for a return to the old days. Men had grown accustomed to Karellen's imperceptible rule—but they were becoming impatient to know who ruled them. And how could they be blamed?
