<passage>:
It would mean instant victory—but for whom? I no one in them. I tried to sit up. It wasn't easy but, by applying a lot more will-power than should be required of a sick man, I made it. that transcended pain. I heaved with the other leg, scrabbled with the charred arm. The crawl to the cabinet dwarfed Hillary's trek up Everest, but I reached it after a couple of years, and found the microswitch on the floor that activated the thing, and then I was I touched his mind, planted a couple of false impressions and withdrew. Gool—if I survived. work. I fumbled my way into a couch and tried to think. In my condition—with a broken leg and third-degree burns, plus a fractured skull—I shouldn't have been able to fall out of bed, much less make the trip from Belshazzar's here—and it was time to get a call through to TSA headquarters. I flipped the switch and gave the emergency call-letters Col. Ausar Kayle of Aerospace Intelligence had assigned to me a few weeks before. an answer—not with a fifteen-minute transmission lag. I plowed on: " was sabotaged. So was Gilgamesh 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 told me yourself that you blacked out during the attack—and came to on "What do I do now?" I stormed. "Go into orbit and eat pills and hope you think of something? I need a doctor!" range of Earth. I had gotten clear of the Gool, but I wouldn't survive my next meeting with my own kind. They couldn't take the chance that I was acting under Gool orders. Maybe there was something in Kayle's suspicion. If the Gool were as mind—and I had been prepared for just such an attack. 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. And found it. As the eye instantaneously detects a flicker of motion amid an infinity of static detail, so my inner eye perceived the subtle traces of the probing Gool mind, like a whispered touch deftly rearranging my buried voices—yet not voices, merely the shape of concepts, indescribably intricate. I saw how the decoy pseudo-personality which I had concretized for the purpose in a hundred training sessions had fought of the alien probe. I watched as the Gool operator took over the motor " " Impossible! Do you forget all my teachings? Cling, though you expend the last filament of your life-force! " Free from all distraction, at a level where comprehension and retention followed the skillful Gool mind as it engraved its commands deep in passage, to leave me unaware of its tampering—at a conscious level. Watching the Gool mind, I learned. been done to me. Hesitantly, I felt for the immaterial fabric of the continuum, warping and manipulating it, copying the Gool probe. Like planes of paper-thin crystal, the polyfinite aspects of reality shifted into focus, aligning themselves. Abruptly, a channel lay open. As easily as I would stretch out my hand to pluck a moth from a night-flower, I reached across the unimaginable obscene gelatinous immensity of the Gool spy as it spasmed in a frenzy I clamped down control. The Gool mind folded in on itself, gibbering. tracing patterns, scanning the flaccid Gool mind.... source, filling an immense natural basin. The Gool clustered at its more favorable position. I probed farther, saw the great cables of living nervous tissue that linked each eating organ with the brain-mass far underground. I traced the passages through which tendrils ran out to immense caverns where told me, were the young of the Gool. Here they built the fleets that beyond belief in endless profusion. No longer would the Gool tribe trough. They would spread out across a galaxy—and beyond. But not if I could help it. 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. Then they had found me, alone, a sole survivor, free from the clutter of the other mind-fields. It had been their misfortune to pick a psychodynamicist. Instead of gaining a patient slave, they had opened the fortress door to an unseen spy. Now that I was there, I would see what I could steal. white sound, plumbed the deepest recesses of hidden Gool thoughts, 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. Matter across space. a Gool robot. But what I have is too big to let you blow it up without 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 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 to the decoy pseudo-personality, leaving my volitional ego free. I "It smacks of mysticism. But I understand what the Gool have done to 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 closed my eyes, reached out—as the Gool mind had reached out to What was that after 'pick up channel forty-three'...?" "Four-oh-two, sheer off there! You're not cleared for re-entry!" "Hey, you birds are mixed up," I protested. "I'm cleared all the way. I It was time to disappear. I blanked off all transmission, hit the controls, following my evasive pattern. And again I reached out— from his chair, crossed the darkened room and threw a switch. The radar screens blanked off.... penetrated the planetary defenses—God knows how. I—" "Later," I snapped. "How about calling off your dogs now? And send "Goodbye, Granthan. Try to understand...." I flipped the switch, sat gripping the couch, my stomach rising with each heave of the floating escape capsule. I had perhaps five minutes. The missiles would be from Canaveral. 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. detonated the remainder of the flight of six missiles. Then I withdrew. I would have a few minutes' stay of execution now. I ducked back, closed my eyes, felt out for his mind. There was a It was easy—if I could only stay awake. I gritted my teeth, pulled myself into the car, crawled to a dark the farce. I pressed the release on the power truss, gingerly unclamped it, then rigged a sling from a strip of shirt tail. I tied the arm to my side as inconspicuously as possible. I didn't disturb the bandages. I needed new clothes—or at least different ones—and something to unencumbered. Unless you wanted to count the walking brace on my right leg and the sling binding my arm.
