They were finally back in a tunnel. Hummin and Seldon had traveled through one when they went from the Imperial Sector to Streeling University in the air-taxi. Now they were in another tunnel, going from Mycogen to … Seldon did not know where. He hesitated to ask. Hummin’s face seemed as if it was carved out of granite and it didn’t welcome conversation.

Hummin sat in the front of the four-seater, with no one to his right. Seldon and Dors shared the backseat.

Seldon chanced a smile at Dors, who looked glum. “It’s nice to be in real clothes again, isn’t it?”

“I will never,” said Dors with enormous sincerity, “wear or look at anything that resembles a kirtle. And I will never, under any circumstances, wear a skincap. In fact, I’m going to feel odd if I ever see a normally bald man.”

And it was Dors who finally asked the question that Seldon had been reluctant to advance. “Chetter,” she said rather petulantly, “why won’t you tell us where we’re going?”

Hummin hitched himself into a sideways position and he looked back at Dors and Seldon gravely. “Somewhere,” he said, “where it may be difficult for you to get into trouble—although I’m not sure such a place exists.”

Dors was at once crestfallen. “Actually, Chetter, it’s my fault. At Streeling, I let Hari go Upperside without accompanying him. In Mycogen, I at least accompanied him, but I suppose I ought not to have let him enter the Sacratorium at all.”

“I was determined,” said Seldon warmly. “It was in no way Dors’s fault.”

Hummin made no effort to apportion blame. He simply said, “I gather you wanted to see the robot. Was there a reason for that? Can you tell me?”

Seldon could feel himself redden. “I was wrong in that respect, Hummin. I did not see what I expected to see or what I hoped to see. If I had known the content of the aerie, I would never have bothered going there. Call it a complete fiasco.”

“But then, Seldon, what was it you hoped to see? Please tell me. Take your time if you wish. This is a long trip and I am willing to listen.”

“The thing is, Hummin, that I had the idea that there were humaniform robots, that they were long-lived, that at least one might still be alive, and that it might be in the aerie. There was a robot there, but it was metallic, it was dead, and it was merely a symbol. Had I but known—”

“Yes. Did we all but know, there would be no need for questions or for research of any kind. Where did you get your information about humaniform robots? Since no Mycogenian would have discussed that with you, I can think of only one source. The Mycogenian Book—a powered print-book in ancient Auroran and modern Galactic. Am I right?”

“Yes.”

“And how did you get a copy?”

Seldon paused, then muttered, “It’s somewhat embarrassing.”
