Standing at the windows a moment later, watching the ships settling down, Czin~ar realized that his hazy suspicions had been correct. The appearance of Clane in the city was part of a planned maneuver that would now run its deadly course. It was a pleasure to know that Lord Clane himself was caught in a trap.

He wasted no time watching a battle that he could not hope to see from the palace in any important detail. Nor did he have the feeling Tews had had months earlier that it was necessary for commanders to know where he was in the early stages of the engagement. He issued quick instructions, ordering the ice-packed box sent after him, and wrote a note for Meewan. Then he rode with a strong escort to the headquarters of the reserve army in the middle of the city.

The reserve contained a barbarian core, but like the main defense of the city it was overwhelmingly made up of slaves. Czinczar's arrival was greeted by a roar of excitement. The cheers did not die down until long afier he had entered the building.

He talked over the situation with some of the slave officers and found them calm and confident. According to their estimates sixty thousand Linnan soldiers had landed in the first wave. That that was exactly the number of barbarians who had originally invaded the city did not seem to occur to the slaves. But the comparison struck Czinczar sharply. He wondered if it was designed to have some symbolic meaning. The possibility made him sardonic. Not symbols but swords spoke the language of victory.

As the afternoon dragged on, the Linnan attack was being held everywhere. The box, still dripping, was delivered from the palace about three. Since there was no longer any immediate danger, Czinczar sent a messenger to Meewan. At three-thirty Meewan came in grinning broailly. He was followed by slave Linnans carrying a sedan chair. In the chair, bound hand and foot, was the acting Lord Leader of Linn. There was complete silence as the chair was set down, and the slaves withdrew.

Clane studied the barbarian leader with genuine interest. Lady Lydia's opinion of the man had impressed him more than he cared to admit.

The question was, could this strong, fine-looking military genius be panicked into thinking that the atom G.o.ds existed? Panicked now, during the next half hour? Fortunately, for the first time in his career as an atomic scientist, he had behind him the greatest power ever developed by the wizards of the fabulous days of the legends. He saw that the impersonal expression on the other's face was transforming into the beginning of contempt.

"By the G.o.d pits," said Czinczar in disgust, "you Linnans are all the same - weaklings every one.

Clane said nothing. He had looked often with regret into mirrors that showed him exactly what Czinczar was seeing. A slim, young man with a face that was white and womanish and ... well, it couldn't be helped.

Czinczar's face changed again. There was suddenly irony in it. "I am speaking," he asked politely, "to Lord Clane Linn? We have not made a mistake?"

Clane couldn't let the opening pa.s.s. "No mistake," he said quietly.

"I came into Linn for the sole purpose of talking to you while the battle was on. And here I am."

It must have sounded ridiculous, coming from a man bound as he was.

The near guards guffawed, and Meewan giggled. Only Czinczar showed no sign. And his marvelous voice was as steady as steel as he said, "I have not the time to flirt with words, nor the inclination. I can see that you are counting on something to save you, and I presume it has something to do with your knowledge of atomic energy."

He fingered the rod of force suggestively. "So far as I can see, we can kill you in less than a second whenever we desire."

Clane shook his head. "You are in error. It is quite impossible for you to kill me."

There was a sound from Meewan. The engnieer came forward. "Czinczar,"

he said darkly, "this man is intolerable. Give me permission to slap his face, and we shall see if his atom G.o.ds protect him from indignity."

Czinczar waved him aside. But he stared down at the prisoner with eyes that were abnormally bright. The swiftness with which tension had come into the room amazed him. And, incredibly, it was the prisoner who had seized the advantage - "Impossible to kill me!" In one sentence he dared them to make the attempt.

There was a crinkle of frown in Czinczar's forehead. He had been careful in his handling of Clane as a matter of common sense, not because he actually antic.i.p.ated disaster. But now, quite frankly, he admitted to himself that the man was not reacting normally. The words Clane had spoken had a ring in them, a conviction that could no longer be ignored.The purpose of his own invasion of the Linnan empire could be in danger.

He said urgently, "I have something to show you. No attempt will be made to kill you until you have seen it. For your part, do nothing hasty, take no action, whatever power you have, until you have gased with understanding."

He was aware of Meewan's giving him an astounded glance.

"Power!" exclaimed the designer and it was like a curse. "The power he has!"

Czinczar paid no attention. This was his own special secret, and there could be no delay.

"Guards "he said "bring the box over here." It was soaking wet when they brought it. It left a dirty trail of water on the priceless rug, and a pool began to acc.u.mulate immediately in the place where it was set down.

There was a delay while sweating men pried off the top. Even the guards at far doors strained to see the contents. A gasp of horror broke the tension of waiting.

What was inside was about eight feet long. Its width was indeterminable, for it seemed to have folds in its body that gave an impression of great size. It had obviously died only a short time before it was packed in ice. It looked fresh, almost alive, there in its case of ice, unhuman, staring with sightless eyes at the ornate ceiling.

"Where did you get it?" Clane asked at last.

"It was found on one of the moons - within hours after a strange ship was sighted."

"How long ago?" The mutation spoke in a steady tone.

"Two years, Earth time."

"It would seem that whoever was in the ship will have departed by now."

Czinczar shook his head. "Miners found a second body exactly like this on a meteorite in a s.p.a.cesuit - seven months ago."

For a long time the mutation gazed down at the creature. Finally he looked, and his eyes met Czinczar's waiting gaze. He said slowly, "What is your theory?"

"A nonhuman race of great scientific attainments. Ruthless, unfriendly - for there are reports of sudden destruction in outlying areas of Europa which puzzled me until this body was found ... I tend to wonder if this might not be a second visitation to the solar system. I cannot give you briefly all the logical relationships I have visualized, but my feeling is that the civilization of the golden age was destroyed by the first visitation."

Clane said, "I am glad that you have shown me this, but what is your purpose in doing so?

Czinczar drew a deep breath. And made his second move to avert the catastrophe suggested by every action and manner of this unorthodox prisoner. He said, "It would be a grave error for either of us to destroy each other's armies."

"You are asking for mercy?"

That was too strong to take. The barbarian showed his teeth in a snarl. "I am asking for common sense," he said.

"It's impossible" said Clane "The people must have their revenge. In victory they will accept nothng less than your death."

The words brought an obscene curse from Meewan. "Czinczar," he shouted "what is all this nonsense? I have never seen you like this. I follow no man who accepts defeat in advance. I'll show you what we'll do with this ... this - " He broke off, "Guards, put a spear into him."

n.o.body moved. The soldiers looked uneasily at Czinczar, who nodded coolly. "Go right ahead," he said. "If he can be killed, I'd like to know."

Still n.o.body moved. It was apparenfly too mild an order, or something of the leader's tension had communicated to the men. They looked at each other, and they were standing there doubtfully when Meewan s.n.a.t.c.hed a sword from one of them and turned toward the bound man.

That was as far as he got. Where he had been was a ball of light.

"Try," came the voice of Clane "to use the rod of force against me."

A fateful pause. "Try. It won't kill you."

Czinczar raised the rod of force and pressed the activator. Nothing happened - Wait! The ball of light was growing brighter.

Clane's voice split the silence tantalizingly. "Do you still not believe in the G.o.ds?"

"I am astonished," said Czinczar "that you do not fear the spread of superst.i.tion more than the spread of knowledge. We so-called barbarians, "he said proudly," despise you for your attempt to fence in the human spirit. We are freethinkers, and all your atomic energy will fail in the end to imprison us."

He shrugged. "As for your control over that ball, I do not pretend to understand it."

At last, he had shocked the mutation out of his ice-cold manner. "You actually," said Clane incredulously, "do not believe in the atom G.o.ds?"

"Guards," shouted Czinczar piercingly, "attack him from every side."

The ball of light flickered but did not seem to move. There were no guards.

"Now do you believe?" Clane asked.

The barbarian looked haggard and old. But he shook his head. "I have lost the war," he mumbled. "Only that I recognize. It is up to you to take up the mantle which has fallen from my shoulders." He broke off. "What in the name of your G.o.ds is that ball?"

"It contains the entire sidereal universe." Czinczar kint his brow and leaned forward as if he were trying to understand.

"The what universe?" he asked at last.

"When you look inside through a hollow tube," Clane explained patiently, "you see stars. It's like a window into s.p.a.ce - only it's not a window. It's the universe itself."

The barbarian leader looked genuinely bewildered, "This universe?" he said blankly.

Clane nodded but made no comment. It hadn't been easy to grasp so vast an idea, even with the written explanations that he had found.

Czinczar shook his head. "You mean the Earth is in there?" He pointed at the glowing sphere.

"It's a fourth-dimensional idea," said Clane; and still he remained patient. He could recognize a bemused man when he saw one. It was not the moment to press any other point.

The barbarian narrowed his eyes and said at last, "How can you get a large object into a smaller one?" His tone appealed for a logical explanation.

Clane shrugged. "When largeness or smallness are illusions of viewpoints, the problem does not exist."

Czinczar scowled at that and straightened. "I have been a.s.suming," he said, "that at this point in our relations you would be speaking nothing but truth. Evidently, you are not prepared to tell me anything valid about your weapon. Naturally, I reject this fanciful story."

Clane shook his head but said nothing. He had given the only explanation he had, and it had run up against the other man's magnificent realism. Not that he blamed the barbarian. Only gradually had he himself been able to accept the idea that matter and energy were different than they appeared to the sense perceptions of the body.

But now it was time to act, to force, to convince. The bonds fell from him as if they did not exist. He stood up, and now that crown among all the jewels of the ages rode above his head in a matchless perfect rhythm with his movements.

Czinczar said stubbornly, "It would be a mistake to kill any able-bodied man, slave or otherwise."

Clane said, "The G.o.ds demand absolute surrender."

Czinczar said in fury, "You fool, I am offering you the solar system!

Has this monster in the box not changed your mind in the slightest degree?"

"It has."

"But then -"

"I do not," said Clane, believe in joint-leadership arrangements."

A pause. Then Czinczar said, "You have come far - who once used atomic power merely to stay alive."

"Yes," said Clane, "I have come far."

Czinczar frowned down at the thing in the box. "The real threat to Linn is there. Will you promise to try for the Lord Leadership?"

"I," Clane said, "can promise nothing."

They looked at each other, two men who almost understood each other.

It was Czinczar who broke the silence. "I make an absolute surrender," he said and it was a sigh, "to you and you alone, of all my forces - in the belief that you have the courage and common sense to shrik none of your new duties as Protector of the Solar System. It was a role," he finished somewhat unnocessarily, suddenly gloomy, "that I originally intended for myself."

In a well-guarded room in a remote suburb of Linn a core of energy rolled sedately back and forth along a narrow path. In all the solar system there was nothing else like that core. It looked small, but that was an illusion of man's senses. The books that described it and the men who had written the books knew but a part of its secrets.

They knew that the micro-universe inside it pulsed with a multiform of minus forces. It reacted to cosmic rays and atomic energy like some insatiable sponge. No submolecular energy released in its presence could escape it. And the moment it reached its own strange variation of critical ma.s.s it could start a meson chain reaction in anything it touched.

One weakness it had, and men had seized upon that in their own greedy fashion. It imitated thought. Or so it seemed. So it seemed.

The great question that Clane, and before him the ancients, asked after observing this remarkable characteristic was: Did this mean that ...

man controlled the universe or that the universe controlled man?

end.
