"What sort of logic," Sir Lewis was saying, "led you to the belief that we would all be here, in Andrew's house?"
Malone forced his mind to consider the question. "Well," he began, "it isn't exactly logic, I guess."
Luba smiled at him. He felt a little reassured, but not much. "You should have phrased that differently," she said. "It's: 'It isn't exactly logic. I guess.'"
"Not guess," Sir Lewis said. "You know. Prescience, Malone. Your precognitive faculty."
"All right," Malone said. "All right. So what?"
"Take it easy," Burris put in. "Relax, Malone. Everything's going to be all right."
Sir Lewis waved a hand negligently. "Let's continue," he said. "Tell me, Malone: if you were a mathematics professor, teaching a course in calculus, how would you grade a paper that had all the answers but didn't show the work?"
"I never took calculus," Malone said. "But I imagine I'd flunk him."
"Because if he can't back up his answer," Malone said slowly, "then it's no better than a layman's guess. He has to give reasons for his answers; otherwise nobody else can understand him."
"Fine," Sir Lewis said. "Perfectly fine. Now--" he puffed at his pipe--"can you give me a logical reason for arriving at the decision you made a few hours ago?"
The danger was coming closer, Malone realized. He didn't know what it was or how to guard himself against it. All he could do was answer, and play for time.
"While I was driving up here," he said, "I sent you a message. I told you what I knew and what I believed about the whole world picture as it stands now. I don't know if you received it, but I--"
Luba spoke without the trace of a smile. "You mean you didn't know?" she said. "You didn't know I was answering you?"
That was the first pebble of the avalanche, Malone knew suddenly--the avalanche that was somehow going to destroy him. "You forced your thoughts into my mind, then," he said as coolly as he could. "Just as you forced decision on the rest of society."
"Now, dammit, Malone!" Burris said suddenly. "You know those bursts take a lot of energy, and only last for a fraction of a second!"
_Of course I didn't force anything on you, Kenneth. I can't. Not all the power of the entire PRS could force anything through your shield. But you opened it to me._
