it; a door opened; there was a dim light. I now noticed behind me a square platform, travelling upward. I tried to run back to it but it was too late. “I am cut off here,” I thought. Where “here” might be, I did not know.
A corridor. A heavy silence. The small lamps on the vaulted ceiling resembled an endless, twinkling, dotted line. The corridor was similar to the “tube” of our underground railways but it was much narrower, and made not of our glass but of some other, very ancient material. For a moment I thought of the underground caves where they say many tried to save themselves during the Two Hundred Years’ War. There was nothing to do but to walk ahead.
I walked, I think, for about twenty minutes. A turn to the right, the corridor became wider, the small lamps brighter. There was a dim droning somewhere. … Was it a machine or voices? I did not know. I stood before a heavy, opaque door, from behind which came the noise. I knocked. Then I knocked again, louder. Now there was silence behind the door. Something clanked; the door opened slowly and heavily.
