“Then is Bastin suffering from delusions, too?”

“Certainly, but that is nothing new in his case.”

“I don’t agree with you, Bickley—about Bastin, I mean. I am by no means certain that he is not the wisest of the three of us. He has a faith and he sticks to it, as millions have done before him, and that is better than making spiritual experiments, as I am sorry to say I do, or rejecting things because one cannot understand them, as you do, which is only a form of intellectual vanity.”

“I won’t argue the matter, Arbuthnot; it is of no use. I repeat that I am mad, and Bastin is mad.”

“How about me? I also saw and experienced these things. Am I mad, too?”

“You ought to be, Arbuthnot. If it isn’t enough to drive a man mad when he sees himself exactly reproduced in an utterly impossible moving-picture show exhibited by an utterly impossible young woman in an utterly impossible underground city, then I don’t know what is.”

“What do you mean?” I asked, starting.

“Mean? Well, if you didn’t notice it, there’s hope for you.”

“Notice what?”

“All that envoy scene. There, as I thought, appeared Yva. Do you admit that?”
