"Secret aliens?" Hys exploded the words in a mixture of surprise and disgust. "Perhaps. The examination will tell us that." "You're either stupid or incompetent," Hys said bitterly. "The heat of Dis has cooked your brains in your head. I'll be no part of this kind of absurd plan." "You must," Brion said, surprised at his own calmness. He could sense the other man's interest hidden behind his insulting manner. "I don't even have to give you my reasons. In another day this world ends and you have no way to stop it. I just might have an idea that could work, and you can't afford to take any chances--not if you are really sincere. Either you are a murderer, killing Disans for pleasure, or you honestly want to stop the war. Which is it?" "You'll have your body all right," Hys grated, hurling the car viciously around a spire of rock. "Not that it will accomplish anything--but I can find no fault with killing another magter. We can fit your operation into our plans without any trouble. This is the last night and I have sent every one of my teams out on raids. We're breaking into as many magter towers as possible before dawn. There is a slim chance that we might uncover something. It's really just shooting in the dark, but it's all we can do now. My own team is waiting and you can ride along with us. The others left earlier. We're going to hit a small tower on this side of the city. We raided it once before and captured a lot of small arms they had stored there. There is a good chance that they may have been stupid enough to store something there again. Sometimes the magter seem to suffer from a complete lack of imagination." "You have no idea just how right you are," Brion told him. The sand car slowed down now, as they approached a slab-sided mesa that rose vertically from the desert. They crunched across broken rocks, leaving no tracks. A light blinked on the dashboard, and Hys stopped instantly and killed the engine. They climbed out, stretching and shivering in the cold desert night. It was dark walking in the shadow of the cliff and they had to feel their way along a path through the tumbled boulders. A sudden blaze of light made Brion wince and shield his eyes. Near him, on the ground, was the humming shape of a cancellation projector, sending out a fan-shaped curtain of vibration that absorbed all the light rays falling upon it. This incredible blackness made a lightproof wall for the recessed hollow at the foot of the cliff. In this shelter, under the overhang of rock, were three open sand cars. They were large and armor-plated, warlike in their scarred grey paint. Men sprawled, talked, and polished their weapons. Everything stopped when Hys and Brion appeared.
