END AS A HERO By KEITH LAUMER Illustrated by SCHELLING [Transcriber's Note: This etext was produced from Galaxy Science Fiction June 1963. Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Granthan's mission was the most vital of the war. It would mean instant victory—but for whom? I I'd done him a favor by taking it. I couldn't hope to pass for a "What ya wanna go out there for? Nothing out there." I touched his mind, planted a couple of false impressions and withdrew. "I'll get out here." from Belshazzar's and how had I managed to dog that port shut? In an emergency a man was capable of great exertions. But "—your report. I won't mince words. They're wondering at your role in the disaster. How does it happen that you alone survived?" "How the hell do I know?" I yelled—or croaked. But Kayle's voice was droning on: "... you Psychodynamics people have been telling me the Gool may have some kind of long-range telehypnotic ability that might make it possible for them to subvert a loyal man without his knowledge. You've warning and without mercy. You were sent out to investigate the "I'm sorry, Granthan. I can't let you land on Earth. I can't accept "What do I do now?" I stormed. "Go into orbit and eat pills and hope knowing what was coming. I couldn't really blame him he was doing I wasn't, of course. I was still the same Peter Granthan, psychodynamicist, who had started out with Dayan's fleet six weeks earlier. The thoughts I was having weren't brilliant, but they were mine, all mine.... But how could I be sure of that? skillful as we thought, they would have left no overt indications of their tampering—not at a conscious level. like any scared casualty, aching to get home and lick his wounds. But I wasn't just any casualty. I had been trained in the subtleties of the Now was the time to make use of that training. It had given me one resource. I could unlock the memories of my subconscious—and see again what had happened. I lay back, cleared my mind of extraneous thoughts, and concentrated on surface into a dreamworld of vague phantasmagoric figures milling in their limbo of sub-conceptualization. I penetrated deeper, broke And found it. As the eye instantaneously detects a flicker of motion amid an infinity " It is a contact, Effulgent One! " " " " It is elusive, Master! It wriggles like a gorm-worm in the eating intricate. I saw how the decoy pseudo-personality which I had concretized for the purpose in a hundred training sessions had fought against the intruding stimuli—then yielded under the relentless thrust of the alien probe. I watched as the Gool operator took over the motor " Almost it eluded me then, Effulgent Lord. Link with this lowly one! " " Impossible! Do you forget all my teachings? Cling, though you expend the last filament of your life-force! " theorized—was no more than a pattern in emptiness.... But a pattern which I could duplicate, now that I had seen what had been done to me. the passages through which tendrils ran out to immense caverns where smaller creatures labored over strange devices. These, my host's memory would transport the spawn to the new worlds the Prime Overlord had discovered, worlds where food was free for the taking. Not sulphur alone, but potassium, calcium, iron and all the metals—riches beyond belief in endless profusion. No longer would the Gool tribe cluster—those who remained of a once-great race—at a single feeding The Gool had evolved a plan—but they'd had a stroke of bad luck. In the past, they had managed to control a man here and there, among man back to Earth under Gool compulsion, to carry out complex sabotage. of the other mind-fields. It had been their misfortune to pick a psychodynamicist. Instead of gaining a patient slave, they had opened white sound, plumbed the deepest recesses of hidden Gool thoughts, fared along strange ways examining the shapes and colors of the concepts of an alien mind. I paused at last, scanning a multi-ordinal structure of pattern within pattern the diagrammed circuits of a strange machine. I followed through its logic-sequence and, like a bomb-burst, its meaning exploded in my mind. From the vile nest deep under the dark surface of the Gool world in its lonely trans-Plutonian orbit, I had plucked the ultimate secret of their kind. concept is too complex to try to describe in words. You'll have to take my word for it. I can build it, though, using standard components, plus an infinite-area antenna and a moebius-wound coil—and a few other things...." I harangued Kayle for a while, and then sweated out his answer. I was getting close now. If he couldn't see the beauty of my proposal, my screens would start to register the radiation of warheads any time now. Kayle came back—and his answer boiled down to "no." I tried to reason with him. I reminded him how I had readied myself for the trip with sessions on the encephaloscope, setting up the cross-networks of conditioned defensive responses, the shunt circuits ego-complex. I might have saved my breath. "I don't understand that psychodynamics jargon, Granthan," he snapped. "It smacks of mysticism. But I understand what the Gool have done to you well enough. I'm sorry." I leaned back and chewed the inside of my lip and thought unkind thoughts about Colonel Ausar Kayle. Then I settled down to solve the problem at hand. I keyed the chart file, flashed pages from the standard index on the And I had a few ideas. III Kayle of Aerospace Intelligence." Kayle's face appeared. "Don't fight it, Granthan," he croaked. "You penetrated the planetary defenses—God knows how. I—" complaints." "We have you pinpointed," Kayle cut in. "It's no use fighting it, to carry out the schemes of the inhuman enemy, this in no way detracts from your gallant attempt. Mr. Granthan, I salute you." The general's arm went up in a rigid gesture. "Stow that, you pompous idiot!" I barked. "I'm no spy!" cities. I followed the coastline, found the Missile Base, flicked through the cluster of minds. "— missile on course " I fingered my way through the man's mind and found the control centers. Men fell on him, dragged him back. "— fool, why did you blow it?

I had to start getting ready for the next act of I needed new clothes—or at least different ones—and something to " I settled into control gently, trying not to alarm the man. I saw through his eyes the dusty box car, the rust on the tracks, the carelessly. "When'd you git so all-fired hungry all of a sudden?" "Put it in a bag. Quick." "Look who's getting bossy—" him say: "Friend o' mine in there—just passin' through." I was discovering that it wasn't necessary to hold tight control over every move of a subject. Once given the impulse to act, he would rationalize his behavior, fill in the details—and never know that the original idea hadn't been his own. his thoughts. It was as though my mind, having learned the trick of communications with others, instinctively reached out toward them.
