And now, looking back, it seems to me that the days of imprisonment which followed were the most terrible I have ever known. Action, no matter of what sort, gives surcease at least from mental agony, and it was agony which we suffered there in our little cell. For with the passing of every day, every hour, the crimson sun above was drawing nearer toward our own by millions of miles. And we, who alone had power to find the cause of the red sun's deflection--we lay imprisoned there in the city of the globe-men, watching doom creep upon our universe. * * * * * Hour followed hour and day followed day, remorselessly, while we lay there, hours and days which we could measure only by the steady circling of the sunlight that slanted through our tiny windows. With each night came cold, a bitter cold that penetrated to our bones, and for all the red splendor of the dying sun above, the days were far from warm. Twice each day the door opened and a guard cautiously thrust in our food, which consisted of a mushy mixture of cooked vegetables and a bottle of red-tinged, mineral-tasting water. We spoke but little among ourselves, except to wonder as to the whereabouts of Sarto Sen. We had heard nothing of him since we had left him and could not know even whether our friend was alive or dead. What our own fate was to be we could not guess, nor, in fact, was even that of much interest to us. A few months longer and we would meet death with all on this planet, when Alto and our own sun crashed together. Whether or not we lived until then was hardly a great matter. Then, ten days after our capture, there came the first break in the monotony of our imprisonment. There was a rattle of bolts at our door; it swung open, and Sarto Sen stepped inside. As the guards outside closed the door my friend sprang toward me, his face eager. "You're all right, Jan Tor?" he exclaimed quickly. "They told me you were unharmed, but I worried--" A phrase in his speech struck me. "They told you?" I repeated. "_They?_" He nodded, his eyes holding mine. "The globe-men," he said, simply. We stared at him, and he stepped swiftly to the door, tried it and found it fast, then came back and sat down beside us. "The globe-men," he repeated solemnly, "those children of Alto, those creatures of hell, who have turned their parent sun from its course to send it crashing into our own, to wipe out our universe." At our exclamations of stunned surprize he was silent, musing, his eyes seeming to gaze out through somber vistas of horror invisible to us. When he spoke again it was slowly, broodingly, as though he had forgotten our presence.
