But a few revisions could change all that—" He rubbed his hands together thoughtfully. "How about it, Jack? Do we have nerve enough to be laughed at? Do you think we could stand a little discredit, making silly asses of ourselves? Because when I finish this book, we'll be really sniffing out "This kid is driving me nuts," said Dorffman through clenched teeth. "He's gone completely hay-wire. Nobody's been able to get near him for three weeks, and now at six o'clock this morning he decides he's "No. Oh, no!" "Then what?" "You think that "It would, I know it would." Lessing shook his head. "I don't think so, Tommy. You know what the monitor is for, don't you?" "It stops things from going out." "I know, I know." Lessing chewed his lip. "I don't like it. We'd better set up a battery on him and try to spot the trouble. And I'm afraid you'll have to set it up. I've got that young Melrose from Chicago to deal with this morning—the one who's threatening to upset the whole Conference next month with some crazy theories he's been playing with. I'll probably have to take him out to the Farm to shut him up." Lessing downstairs." "Full psi precautions?" asked Dorffman. "Certainly! And Jack—in this case, be sure of it. If Tommy's in the trouble I think he's in, we don't dare risk a chance of Adult Contact now. We could end up with a dead boy on our hands." Two letters were waiting on Lessing's desk that morning. The first was from Roberts Bros., announcing another shift of deadline on the book, Lessing groaned. As director of psionic research at the Hoffman Medical get back to work again. The other letter cheered him a bit more. It bore the letterhead of the stronghold of psionic research at last. And face to face with the a brand spanking new one, just fresh out of the pupa, so to speak!" He touched his forehead in a gesture of reverence. "I bow before the Oracle. Speak, oh Motah, live forever! Cast a pearl at my feet!" "If you've come here to be insulting," Lessing said coldly, "you're unless I like everything I see and hear down here today. And if you don't think I can do it, you're in for quite a dumping." Connecticut and see for myself how much pressure these experimental controls you keep talking about will actually bear. But mostly, I want false as Satan." "And our controls are above suspicion." "So far, we haven't found any way to set up logical controls," said Melrose. "We've done a lot of work on it, too." "Oh, yes—I've heard about your work. Not bad, really. A little misdirected, is all." "According to your Theory, that is." "Wildly unorthodox approach to psionics—but at least you're energetic enough." "I've got 'til New Year." Lessing shouted for his girl. "Get Dorffman up here. We're going to the Hoffman Center. They sat in silence as the car dipped down into the rapid-transit channels beneath the great city, swinging northward in the express circuit through Philadelphia and Camden sectors, surfacing briefly in Trenton sector, then dropping underground once again for the long pull beneath Newark, Manhattan and Westchester sectors. In less than twenty minutes the car surfaced on a Parkway channel and buzzed "What about Tommy?" Lessing asked Dorffman as the car sped along through the afternoon sun. "I just finished the prelims. He's not cooperating." "It's—unconventional, at any rate," Lessing snapped. "Well, that depends on your standards. Sounds like a country day school, from what I've heard. According to your papers, you've even "That's right," said Lessing. "We don't." "And you don't know why all. It's not inconceivable that the children might be measuring the , eh?" Lessing blinked. "It's conceivable." "Mmmm," said Melrose. "Sounds like a real firm foundation to build a quality of the human mind. Just as the ability to think logically in a crisis instead of giving way to panic is a differentiating quality." "Fine," said Melrose. "Great. We can't prove that, of course, but I'll play along." underground? What buries it so deeply that adult human beings can't get at it any more?" "And you think you have an answer," said Melrose. "We think we might be near an answer. We have a theory that explains long, low building. "All right, young man—come along," said Lessing. "I think we can show you our answer." them to. Our goal is a perfectly controlled psi environment. The monitors are quite effective—a simple Renwick scrambler screen." effective for our purposes." "But you don't know why," added Melrose. "All right, we don't know why. Nobody knows why a Renwick screen so far afield at that—with scholarships supported by Hoffman Center without the "Those three seem to work as a team, somehow. Each one, individually, had a fairly constant recordable psi potential of about seventeen on the arbitrary scale we find useful here. Any two of them scale in at thirty-four to thirty-six. Put the three together and they operate somewhere in the neighborhood of six hundred on the same scale." Lessing smiled. "This is an isolated phenomenon—it doesn't hold for "But that wouldn't make any difference, would it? The blocks still fall down." suddenly, his voice earnest. "You have fine facilities here, good workers. And in spite of my flippancy, Dr. Lessing, I have never firmly out of his mind. But somehow Melrose wouldn't force. "Stop worrying about it," Dorffman urged. "He's a crackpot. He's crawled way out on a limb, and now he's afraid your theory is going to cut it off under him. Well, that's his worry, not yours." Dorffman's from any other, Jack. It doesn't follow the rules. Maybe scientific grounds aren't right at all, in this case." Dorffman snorted. "Surely there's nothing wrong with theorizing—" "He wasn't objecting to the theory. He's afraid of what happens after the theory." "So it seems. But why?" "He seems to, you mean. And therefore, anything he says about it defends them for all he's worth ." "But why shouldn't he?" "Because a man can't fight for his life and reputation and still keep his objectivity," said Lessing. "And what if he just happens to be wrong? Once he's an Authority the question of what's right and what's wrong gets lost in the shuffle. It's what he says that counts." "But we know you're right," Dorffman protested. "Do we?" gripping a toy fire engine tightly in his hands. Lessing crossed the room swiftly. "Tommy," he said. horribly wrong—could the boy really be sensing the source of the trouble? Lessing felt a cold knot gather in the pit of his stomach. He before. There must be an error." "Of course," said Lessing. "According to the theory. The theory says their potential through repeated contact until it dries up completely. We've proved that, haven't we? Time after time. Everything goes according to the theory—except Tommy. But Tommy's psi-potential was balance of his mind. Then he made an adult contact, and we saw how he bloomed." Lessing sank down to his desk wearily. "What are we going to do, Jack? Formulate a separate theory for Tommy?" ?" Lessing burst out. "Didn't you see how he acted head. "It's no good, Jack. Something different happened here, something we'd never counted on. It's something the theory just doesn't allow for."
