Reconstructing what had happened was not hard. Raver must have crept close during the night, lain there, then walked in at dawn, just one more space-suited man. He had put a bomb of some kind in among the tanks, then escaped in the confusion following the blast. N'Ness had underestimated him.
"He will pay for it," the lieutenant said coldly. "He lost his lead by coming back to do this — and he will not regain it. Fall in and check tanks."
The spare oxygen cylinders were gone, but there was still some oxygen left in the suit tanks. With ruthless efficiency N'Ness bled these tanks into his, until his was full and the others close to empty. "Get back to the ship," he ordered. "As soon as you get past these last hills use your radio; you should be able to raise either the ship or the mine. Tell them to bring oxygen out to meet you in case you don't have enough to make it all the way. I'm going on and I'll bring the prisoner back. Report that to the captain. Now move out."
N'Ness did not watch them go, in fact he had already forgotten their existence. He was going to catch Raver. He was going to march him back at gunpoint. It would make the captain very happy and it would look very good on his record. He almost ran up the slope ahead.
The lieutenant was the lighter man, he was more lightly burdened, and he had the advantage of being the follower, not the pathfinder. Where Raver had worked his way around a difficult patch of broken rock, N'Ness went straight through, counting upon his speed and agility. He did not slow nor rest and his panting breath was echoed by the whine of the conditioning unit as it labored to remove the excess water vapor and heat. It was an insane chase, but as long as he did not slip or collapse from exhaustion it could have only one end.
Raver pulled himself up onto the broad ledge and through a gap in the rocks he could see the tall pithead workings of the Puliaan mines. He started forward when his radio crackled in his ear, and N'Ness's voice said, "Just hold it, right where you are." He stopped dead and looked slowly around.
Lieutenant N'Ness stood on the ledge above, pointing his energy rifle. "Turn around," N'Ness said, "and start right back where you came from." He waggled the muzzle of the gun in the correct direction.
"Thank you, no," Raver said, sitting down and slinging the oxygen tank to the ground. "I have no intention of returning, in spite of your invitation."
"Enough talk. You have ten seconds to start moving — before I pull this trigger."
"Pull and be damned. I die here or I die back there. What difference does that make to me?"
N'Ness had not expected this, and he had to think a moment before he answered. The steel edge of command was gone from his voice when he finally spoke. "You're a reasonable man, Raver. There's no reason to die out here, not when you can live and work…"
"Don't act stupid, the role doesn't become you. We both know that mine slaves are there for life — and a short life at that. There'll be no more chances to escape. You're the paid killer. Shoot."
N'Ness estimated the reserves in his tank and the spare Raver carried and sat down himself. "You can leave out the insults," he said. "I may have killed men in the line of duty, but I've never tortured or butchered people the way your so-called Pacifist Party—"
"Stop," Raver ordered, lifting his head. "You're a victim of your own propaganda. It's all lies. We do not kill. Think for yourself, if you are able to. Have you ever seen any of the atrocities committed that you speak about? Other than by your own people, that is."
"I'm not here to argue with you…"
"Unsatisfactory, try again. Have you seen these things?"
''No, I haven't — but that's only because we shot first and fast before they could happen."
"Just as unsatisfactory, Lieutenant. You are avoiding the truth. You kill, we do not. That is the basic and important difference between us. You are the animal heritage of mankind, we are its future."
"Not so holy, please. You attacked the guard on the ship, and last night you tried to kill me and my men."
"That is not true. I do not kill. I rendered the guard unconscious ar*d I used the guard's rifle and ammunition as a bomb to destroy your oxygen, to force you to turn back. Was anyone injured?"
"No,! but— "
"Yes, but.” Raver said loudly, jumping to his feet. "That is all the difference. Our aggressive traits brought us to the top of the animal kingdom, now we must renounce killing if we are to progress. We have this violence within us — I don't deny I have it myself — but what good is our intellect if we cannot control it? Any man can desire a woman he sees in the street or jewelry in a display window, yet only the sick men rape and steal. We all possess the capacity for violence. Only the sick man kills."
"Not sickness," N'Ness said, waggling the gun in Raver's direction. "Just good sense. This wins arguments. The sensible man knows he can't fight a gun, so he gets one himself and evens the score. That's something you people will never learn. We always win. We kill you."
"Yes, you kill us in great numbers, but you cannot win. You do not change a man's mind by eliminating him. What do you do when everyone is on the other side? Shoot them all? And after you have killed every man, woman, and child — what do you do with your world?"
"You're being stupid now. This has been tried before, and whenever the leaders are killed the mob does what it is told."
"Then there is something new come into the universe.” Raver said quietly. "Perhaps it is the next development, Homo superior, a mutation, men who are constitutionally unable to kill. This is not my theory, there have been scientific papers written on it…"
"All nonsense!"
"Not really. Look at what happened on Puliaa."
"Propaganda. The Pacifist Party there may be temporarily in power, but watch what happens at the first sign of trouble."
"They've had their trouble and they've weathered it well so far. And it is truth that a worldwide nonviolent rebellion put them into power. It is what everyone wanted."
"Lies!"
"I doubt it." Raver smiled. "You can't ignore the fact that the entire planet is now vegetarian. Something happened. Why don't you look into it before it is too late? I'm not the first one to believe that those who live by the sword die by it."
"That's enough talk," N'Ness said, standing. "You'll come back with me now."
"No."
"If you don't come I'll shoot you down, now, and send men for your body. You have no choice."
"Would you do that? Just pull the trigger and kill a man? Remove a life for no reason? I find it hard to imagine; I am incapable of such an evil act."
"It is not evil — and I have good reason. You are an enemy, I have orders…"
"Those are not reasons, just excuses. An animal kills to eat or in defense of its life, or the lives of others. All else is corruption."
"One last warning," N'Ness said, aiming the gun steadily at the other's midriff. "Your arguments mean nothing. Come with me or I shoot you."
"Don't do this to yourself, Lieutenant. Here is a chance rarely offered to your kind. You can stop killing. You can go with me to Puliaa and discover what it is like not to be an animal. Don't you realize the rapist rapes himself? Who would want to live in the head of a rapist? So does the killer kill himself, and this is probably the only kind of killing a man of peace can understand. We do not like it, but by necessity we accept it. Only when your kind is gone can my kind make this galaxy the place it should be."
"You fool," the lieutenant shouted. "You're dying, not me. Your last chance."
"You kill yourself," Raver said calmly. The lieutenant's lips pulled back from his teeth and he shouted with rage as he pulled the trigger.
The gun blew up, killing him instantly.
