He didn't feel like a ghost. He wondered just how a ghost would act, anyhow. What was more, he could not understand such a queer assumption on the Rhamda's part. Why had he seemed to WANT Chick a ghost? Watson was natural, human, embodied, just like the Rhamda. This was scarcely his idea of a phantom's life. Most certainly, the two of them were men, nothing else; if one was a wraith, so was the other. But—how to account for it?

Again he thought of Rhamda Avec. The words of Geos, “The Fact and the Substance,” had been exactly synonymous with what had been said of Avec by Dr. Holcomb, “The proof of the occult.”

Was it indeed possible that these two great ones, from opposite poles, had actually torn away the veil of the shadow? And was this the place where he, Watson, must pose as a spirit, if he were to be accepted as genuine?

The thought was a shock. He must play the same part here that the Rhamda had played on the other side of the Spot; but he would have to do it without the guiding wisdom of Avec. Besides, there was something sinister in the unknown force that had engulfed so strong a mind as the professor's; for while Watson's fate had been of his own seeking, that of the doctor smacked too much of treachery.

He turned to the Rhamda Geos with a new question:

“This Rhamda Avec—was he a man like yourself?”

The other brightened again, and asked in return:

“Then you have seen him!”

“I—I do not know,” answered Watson, caught off his guard. “But the name is familiar. I don't remember well. My mind is vague and confused. I recall a world, a wonderful world it was from which I came, and a great many people. But I can't place myself; I hardly—let me see—”

The other nodded sympathetic approval.
