The moment came without announcement. Heim cast a glance behind and stopped dead. “
Between the lifting of fog and its own nearness, the thing had become visible a kilometer or so to their rear. It was another machine like the one they had found. But a twisted, weather-eaten detector frame still rose above the turret, and the body moved … slowly, crippledly, loose parts vibrating aloud, air-blower spitting and jerking, the whole frame ashudder, it moved in their wake.
Jocelyn suppressed a cry. Bragdon actually jumped backward a step. Panic edged his tone: “What’s that?”
Heim beat down his own quick fear. “An abandoned vehicle,” he said. “Some kind of automaton. Not quite worn out. Scarcely any moving parts, you know.”
“But it’s following us!” Jocelyn quavered. “Probably set to patrol an area, home on any life it detects, and—” A crazy hope fluttered through Heim’s brain, unshared by his guts. “Maybe we’re being offered a ride.”
“No.” Vadász’s helmet rolled with headshaking. “I do not trust the looks.”
Heim ran a tongue which had gone wooden over his lips. “It’s moving quicker than we can, I think,” he
Vadász and Jocelyn caught his arms simultaneously. He shook them off. “Damnation, I’m still the captain,” he rapped. “Let me be. That’s an order.”
He started off. The hurt in his muscles dwindled. Instead there came an odd, tingling numbness. His mind felt unnaturally clear, he saw each twig and leaf on the haggard bushes around, felt how his feet struck soil and the impact that traveled through shins to knees, smelled his own foulness, heard the geysers boom at his back. Earth seemed infinitely remote, a memory of another existence or a dream he had once had, unreal; yes, despite its vividness this world was unreal too, as hollow as himself.
He walked on. There was nothing else to do. The detector lattice swiveled stiffly about, focused invisible unfelt energies on him. The robot changed direction to intercept Several armor plates clashed loose. Blackness gaped behind them. The whole body was leprous with metal decay.
The turret rotated. A port tried to open, got halfway, and stuck. The machine grated inside. Another port at the front of the body slid back. A muzzle poked forth. The slug-thrower spoke.
Heim saw dirt fly where the bullets hit, a hundred meters short He whipped about and ran. The thing growled. Swaying on an unstable air cushion, it chased him. The gun raved a minute longer before stopping.
He reached the others, stumbled, and rolled, in a heap. For a minute he lay half stunned. Vadász and Uthg-a-K’thaq helped him rise. Jocelyn hung onto his hand and wept “I thought you were dead. I thought you were dead.”
“He would be,” said Vadász, “but explosives have deteriorated … Watch out!”
Another port had opened, another tube thrust clear. Across the distance, through a red blur in his vision, Heim saw coils, a laser projector, and lasers don’t age. He grabbed Jocelyn to pull her behind him. A beam sickled, brighter than the sun. It struck well to the left Bushes became charcoal and smoke. The beam traced a madman’s course, boiled a rivulet, shot skyward, winked out.
“The aiming mechanism,” Uthg-a-K’thaq said. For once his own voice was shaken. “Has worn to uselessness.”
“Not if the thing gets close,” Bragdon whimpered. “Or it can slugger us, or crush us, or—Run!”
