“I don’t know that, either; but I hope to find out through you. I read, and studied, and tried, and all of a sudden—bang!—there it was. But words are useless; I’m coming into your mind. Now watch me closely, concentrate: really concentrate, as hard as you possibly can. Ready? It goes like this . . . did you get it?”

“No. I couldn’t follow the details—it seemed like an instantaneous transition. Didn’t you have more to begin with than I’ve got?”

“I don’t think so . . . pretty sure I didn’t. I could receive—I think it’s impossible for anyone to become a telepath who can’t—but I couldn’t send a lick. My psi rating was a flat zero zero zero. Now try it again. Take a good, solid grip on a thought and throw it at me.”

“QX. I’ll try.” Cloud’s forehead furrowed, his muscles tensed in effort. “Since you already know I’ve been wondering why you never married—why? Standards too high?”

“You might call it that.” It was the woman’s turn to blush, but her thought was clear and steady. Cloud was working with her better than he had ever worked with either Luda or Nadine. “Since the days of my teen-age crushes on tri-di idols I simply haven’t been able to develop any interest in a man who didn’t have as much of a brain as I have, and the only such I met were either already married or didn’t have anything except a brain—which wouldn’t do, either, of course.”

“Of course not.” Cloud felt something stirring inside him that he thought completely dead, and tried, in near-panic fashion, to kill it again. He changed the subject abruptly. “No luck—I’m not getting through to you at all. We’d better start all over, at the bottom. What’s the first thing I’ve got to do to learn to be a snooper?”

“You must learn how to concentrate—intensively and in a very special way. You’re very good at ordinary concentration—especially mathematical stuff—now; but this kind is different—so much so as to be a difference in kind, not merely of degree.”

“Check. Point one, a new kind of concentration. Next?”

“No next. That’s all. When you get so you can concentrate correctly—I’ll coach you mind to mind on that, of course—we’ll concentrate together, first on one gateway, then another. Something will click into place, and there you’ll be.”

“I hope. But suppose it doesn’t? Can’t it be worked out? You’re on record as saying that the mind is simply a machine.”
