rock, without sun or shelter. He said,
"She'd never have you, Hilton. And I'll tell you this. Perhaps I can't force out of you what you know. But if I can't, I swear to God I'll kill you with my own hands."
He threw back his head and laughed suddenly. "Gantry Hilton's son—in love with an Unregenerate!"
"Wait, Eric." Sheila Moore put a hand on his arm to stop him, and went forward. She took Miner Hilton by the shoulders and looked up at him, and said,
"It isn't so impossible, Miner Hilton. Not if what I think is true."
Falken stared at her in stunned amazement, beyond speech or movement. Then his heart was torn with sudden pain, and he knew, with the clarity of utter truth, that he loved Sheila Moore.
She said to Miner Hilton, "Why did you do this? And how?"
Young Hilton's voice was flat and strained. He made a move as though to take her hands from his shoulders, but he didn't. He stared across her red-gold head, at Falken.
"Something had to be done to stamp out the Unregenerates. They're a barrier to complete peace, a constant trouble. Eric Falken is their god, as—as Sheila said. If we could trap him, the rest would be easy. We could cure his people.
"My father couldn't do it himself. He's old, and too well-known. He sent me, because mine is the only other brain that could stand what I had to do. My father has trained me well.
"To get me by the psycho-search, my father gave me a temporary brain pattern. After I was accepted as a refugee, I established mental contact with him...."
"Mental contact," breathed Falken. "That was it. That's why you were always so tired, why I couldn't shake pursuit."
"Go on," said Sheila, with a queer gentleness.
Hilton stared into space, without seeing.
"I almost had you in Losangles, Falken, but you were too quick for the Guards. Then, when we were trapped at Mercury, I tried to make you sleep. I was leading those ships, too.
"But I was tired, and you fought too well, you and Sheila. After that we were too close to the Sun. My thought waves wouldn't carry back to the ships."
He looked at Falken, and then down at Sheila's thin face.
"I didn't know there were people like you," he whispered. "I didn't know men could feel things, and fight for them like that. In my world, no one wants anything, no one fights, or tries.... And I have no strength. I'm afraid."
Sheila's green eyes caught his, compelled them.
"Leave that world," she said. "You see it's wrong. Help us to make it right again."
In that second, Falken saw what she was doing. He was filled with admiration, and joy that she didn't really care for Hilton—and then doubt, that perhaps she did.
Miner Hilton closed his eyes. He struck her hands suddenly away and stepped back, and his blaster came ready into his hand.
"I can't," he whispered. His lips were white. "My father has taught me. He trusts me. And I believe in him. I must!"
Hilton looked where the glow of the Sun-child pulsed against ebon rock. "The Unregenerates won't trouble us any more."
He raised the muzzle of his blaster to his head.
* * * * *
It was then that Falken remembered his was empty. He dropped it and sprang. He shocked hard against Hilton's middle, struck him down, clawing for his gun arm. But Hilton was heavy, and strong.
He rolled away and brought his barrel lashing down across Falken's temple. Falken crouched, dazed and bleeding, in the mud.
He laughed, and said, "Why don't you kill me, Hilton?"
Hilton looked from Falken's uncowed, snarling face to Sheila. The blaster slipped suddenly from his fingers. He covered his face with his hands and was silent, shivering.
Falken said, with curious gentleness, "That proves it. You've got to have faith in a thing, to kill or die for it."
Hilton whispered, "Sheila!" She smiled and kissed him, and Falken looked steadfastly away, wiping the blood out of his eyes.
Hilton grasped suddenly at the helmet of his vac-suit. He talked, rapidly, as he worked.
"The Sun-child creates with the force of its mind. It understands telekinesis, the control of the basic electrical force of the universe by thought, just as the wise men of our earth understood it. The men who walked on the water, and moved mountains, and healed the sick.
"We can only attack it through its mind. We'll try to weaken its thought-force, destroy anything it sends against us."
His fingers flashed between the helmet radio and the repair kit which is a part of every vac suit, using wires, spare parts, tools.
"There," said Hilton, after a long time. "Now yours."
Falken gave him his helmet. "Won't the Sun-child know what we're doing?" he asked, rather harshly.
Hilton shook his fair head. "It's weak now. It won't think about us until it has fed. Perhaps two hours more."
"Can you read its thoughts?" demanded Falken sourly.
"A very little," said Hilton, and Sheila laughed, quietly.
Hilton worked feverishly. Falken watched his deft fingers weaving a bewildering web of wires between the three helmets, watched him shift and change, tune and adjust. He watched the sun-child throb and sparkle as the strength of the Sun sank into it. He watched Sheila Moore, staring at Hilton with eyes of brilliant green.
He never knew how much time passed. Only that the Sun-child gave a little rippling sigh of light and floated down. The fissure closed above it. Sheila caught her breath, sharp between her teeth.
Hilton rose. He said rapidly.
"I've done the best I can. It's crude, but the batteries are strong. The helmets will pick up and amplify the energy-impulses of our brains. We'll broadcast a single negative impulse, opposed to every desire the Sun-thing has.
"Stay close together, because if the wires are broken between the helmets we lose power, and it's going to take all the strength we have to beat that creature."
Falken put on his helmet. Little copper discs, cut from the sheet in the repair kit and soldered to wires with Hilton's blaster, fitted to his temples. Through the vision ports he could see the web of wires that ran from the three helmets through a maze of spare grids and a condenser, and then into the slender shaft of a crude directional antenna.
Hilton said, "Concentrate on the single negative, No."
Falken looked at the lovely shimmering cloud, coming toward them.
"It won't be easy," he said grimly, "to concentrate."
Sheila's eyes were savage and feral, watching that foam of living flame. Hilton's face was hidden. He said,
"Switch
