"What then?"
"You will let me try?"
"What would you do?"
"I have said to you that thoughts are things. Now I wish to prove it to you, and to show you that which is only a thought. Yes, yes, I can do it and you will see. Now I ask you only to sit still and say nothing, and keep ever your hands quiet upon the table."
The room was blacker and more silent than ever. The same feeling of apprehension which had lain heavily upon me at the beginning of the séance was back at my heart once more. The roots of my hair were tingling.
"It is working! It is working!" cried the Frenchman, and there was a crack in his voice as he spoke which told me that he also was strung to his tightest.
The luminous fog drifted slowly off the table, and wavered and flickered across the room. There in the farther and darkest corner it gathered and glowed, hardening down into a shining core—a strange, shifty, luminous, and yet non-illuminating patch of radiance, bright itself, but throwing no rays into the darkness. It had changed from a greenish-yellow to a dusky sullen red. Then round this centre there coiled a dark, smoky substance, thickening, hardening, growing denser and blacker. And then the light went out, smothered in that which had grown round it.
"It has gone."
"Hush—there's something in the room."
We heard it in the corner where the light had been, something which breathed deeply and fidgeted in the darkness.
