I began to speak to Tillinghast, and as I did so all the unusual impressions abruptly vanished. I saw only the man, the glowing machine, and the dim apartment. Tillinghast was grinning repulsively at the revolver which I had almost unconsciously drawn, but from his expression I was sure he had seen and heard as much as I, if not a great deal more. I whispered what I had experienced, and he bade me remain as quiet and receptive as possible.
