intercom began feeding out a long sheet of paper the new answer from the Brain. It reached a certain length, then was automatically sheared off within the intercom, and the sheet fell gently to the desktop. in the ad agency where he worked. So when the Chief of World Security told him that he had been selected as the answer to the Solar System's greatest mystery, Jery assumed that it was because of his mental agility. But when he got to Mars to find out why fifteen boys had vanished from a spaceship in mid-space, he found out that even his quick mind needed Oddly enough, it worked out, and he now does nothing else. He says, "I'd like to say I do this for fulfillment, or for cash, or because it's my destiny however, the real reason (same as that expressed by Jean Kerr) is that this kind of stay-at-home self-employment lets me the time they spoke to me, but in that miniscule interval I managed to retrace quite a bit of my lifetime up till that moment, seeking vainly for some reason why they'd be standing there, so terribly and So I managed a weak smile toward the duo, and tried not to sweat too profusely. "... Yes," I said, some terrified portion of my mind waiting masochistically for them to draw their collapsers and reduce me to a heap of hot protons. "Come with us," said his companion. I stared at him, then glanced to nod. He shook his white-maned head, slowly. "I don't believe it." "But I am, sir," I insisted doggedly. "I'd rather not discuss that, sir, if you don't mind." "Do you mind if I do mind?" "Oh ... Oh, well if you put it like that. It's girls, sir. They block my mind. Ruin my work." "I don't get you." I sat back, feeling much better. "That's right, sir." Then Baxter frowned again. "But what's this about girls?" "They—they block my thinking, sir, that's all. Why, take that example is.... You have been chosen for an extremely important mission." I couldn't have been more surprised had he announced my incipient maternity, but I was able to ask, "Me? For Pete's sake, why, sir?" be. Otherwise, why was I sent for?" "Believe me, I wish I knew," he sighed. "You were chosen, from all the inhabitants of this planet, and all the inhabitants of the Earth Colonies, by the Brain." "You mean that International Cybernetics picked me for a mission? That's crazy, if you'll pardon me, sir." Baxter shrugged, and his genial smile was a bit tightly stretched. "When the current emergency arose and all our usual methods failed, we had to submit the problem to the Brain." "And," I said, beginning to be fascinated by his bewildered manner, "what came out?" "Yes, but read me the part where it says why I was picked," I said, a little exasperated. to make. IC had none to make. Damn it all to hell!" He brought a meaty fist down on the desktop. "No one has an explanation! All we know is that the Brain always picks the right man." I let this sink in, then asked, "What made you ask for a man in the first place, sir? I've always understood that your own staff represented some of the finest minds—" "Hold it, son. Perhaps I didn't make myself clear. We asked for no man. ceiling, then continued. "You've heard, of course, of the Space Scouts?" I nodded. "Like the old-time Boy Scouts, only with rocket-names for their various troops in place of the old animal names." "And you recall the recent government-sponsored trip they had? To Mars all. "Inter-nation harmony! Good will! If these mere boys can get together and travel the voids of space, then so can everyone else! Why Where was I?" "You were telling about how this gesture, the WG sending these kids off for an extraterrestrial romp, will cement relations between those nations who have remained hostile despite the unification of all governments on Earth. Personally, I think it was a pretty good idea, myself. Everybody likes kids. Take this jam we were trying to push. what happened to the Space Scouts last week?" Space Scouts have vanished." I came up in the chair, ramrod-straight. "Their mothers—they've been getting letters and—" men are doing the work. Handpicked crews, day and night, have been sending those letters to the trusting mothers. It's been ghastly, Delvin. Hard on the men, terribly hard. Undotted "And your men haven't found out anything?" I marvelled. Baxter shook his head. "And you finally had to resort to the Brain, and it gave you my name, but no reason for it?" Baxter cupped his slightly jowled cheeks in his hands and propped his form of an electronic brain, and even works on the same principle—can tell you that two and two make four. But can it tell you why? "Well, no, but—" "That, in a nutshell is our problem. We coded and fed to the Brain every shred of information at our disposal the ages of the children, "Then I'm to be sent to Mars?" I said, nervously. "They disappeared from a spaceship? While in space?" spaceport. Even so, they'd shuttled it into a hangar, safe from the I started back for Interplanetary Security, and my second—and I hoped, last—interview with Chief Baxter. I had a slight inkling why the Brain had chosen me because, in the affair of the missing Space Scouts, my malevolent with the pilot. And I'm ordinarily on the shy side, as a matter of fact." "It's the Amnesty that does it," he said, gesturing toward the disc. It lay on his desk, now, along with the collapser. I felt, with the new information I'd garnered, that my work was done, and that the new data fed into the Brain would produce some other results, not involving me. I looked at the Amnesty, then nodded. "Kind of gets you, after awhile. To know that you are the most influential person in creation is to automatically act the part. A shame, in a way." "The hell it is!" Baxter snapped. "Good grief, man, why'd you think the Amnesty was created in the first place?" I sat up straight and scratched the back of my head. "Now you mention course, was a person who could simply have all authority, in order to save the sometimes disastrous delays. So we came up with the Amnesty." committee or bureau or any other faction to do the picking. Hell, that would have put us right back where we'd been before. No, we left it up to the Brain. We'd find ourselves in a tight situation, and the Brain after being fed the data, would come up with either a solution, or a name." I stared at him. "Then, when I was here before, I was here solely to receive the Amnesty, is that it?" Baxter nodded. "The Brain just picks the men. Then we tell the men the situation, hand over the Amnesty, and pray." I had a sudden thought. "Say, what happens if two men are selected by the Brain? Who has authority over whom?" Baxter grimaced and shivered. "Don't even think such a thing! Even your mentioning such a contingency gives me a small migraine. It'd be late to go back to work. I'd done a lot in one day, I reasoned. Well, the thing was out of my hands. Baxter had the information I'd come up with, and it had been coded and fed to the Brain. As soon as the solution came through, I could be on my way back to the world of hard and soft sell. whatever about the disappearance of the Space Scouts until this office
