That is, it takes a certain amount of time to get from point A to point B. Conversely, time is measured by extension in space. On Earth, a day of time passes when Earth moves through space on an arc one three-hundred-sixty-fifth of its orbit around the sun in length. Since there isn’t any time to measure extension with in hyper-space, since time doesn’t exist here, you can’t speak of mid-points.”

“But this—shoal. It’s always encountered in hyper-space between Earth and Irwadi?”

Ramsey nodded. “Yes, that is right.”

Margot smiled.

The smile suddenly froze on her face.

The Enterprise lurched as if an unseen giant hand had slapped it.

[p 115]
At that moment Ramsey leaned forward over the controls, battling to bring the Enterprise back on course.

And let down his mental guard.

… precise place in hyper-space her father must have meant … home of proto-man … thinks I’m going to stop there, she’s crazy … heck, I’m no mystic, but there are things not meant to be meddled with …

The ship swooped again. Ramsey went forward against the control panel head-first and fell dazed from the pilot chair. His head whirled, his arms and legs were suddenly weak and rubbery. He tried to stand up and make his way back to the controls again, but collapsed and went down to his knees. He crouched there, trying to shake the fog from his brain.

With a cry of triumph, Margot Dennison leaped at him and bore him down to the floor with her weight. He was still too dazed from the blow on his head to offer any resistance when her strong hands tugged at his belt and withdrew the m.g. gun. She got up with it, backing away from him quickly toward the rear bulkhead as the ship seemed to go into a smooth glide which could be felt within it. Vardin stood alongside Ramsey, a hand to her mouth in horror. Ramsey got up slowly.

“Stay where you are!” Margot cried, pointing the m.g. gun at him. “I’ll kill you if I have to. I’ll kill you, Ramsey, I mean it.”

Ramsey did not move.

“So you knew about my father,” Margot challenged him.

“Yeah. So what?”

“And this shoal in hyper-space is a world, isn’t it?”

Ramsey nodded. “I think so.”

“O.K. Sit down at the controls, Ramsey. That’s right. Don’t try anything.”

Ramsey was seated in the pilot chair again. His head was still whirling but his strength had returned. He wondered if he could chance rushing her but told himself she meant what she said. She would kill him in cold blood if she had to.

“Bring the Enterprise down on that world, Ramsey.”

He sat there and stubbornly shook his head. “Margot, you’ll be meddling with a power beyond human understanding.”

“Rubbish! You read my father’s letter, didn’t you? That fear’s been implanted in [p 116] your genes. It’s part of the heredity of our people. It’s rubbish. Bring the ship down.”

Still Ramsey did not move. Vardin looked from him to Margot Dennison and back again with horror in her eyes.

“I’ll count three,” Margot said. “Then I’ll shoot the Vegan girl. Do you understand?”

Ramsey’s face went white.

“One,” Margot said.

Vardin stared at him beseechingly.

Ramsey said: “All right, Margot. All right.”

Five minutes later, subjective time, the Enterprise landed with a lurch.

That they had reached a world in hyper-space there could be no doubt. But outside the portholes of the little freighter was only the murky grayness of the timeless hyper-space continuum.

“They’ve gone down, sir!” Ramar Chind cried.

Garr Symm nodded. For the first time he was really nervous. He wondered about the Dennison letter. Could his fear be attributed to ancestral memory, as Dennison had indicated? Was it really baseless—this crawling, cold-fingered hand of fear on his spine?

There was no physical barrier. The Enterprise had established that fact. Then was there a barrier which Garr Symm, along with all humanoids, had somehow inherited?

A barrier of stark terror, subjective and unfounded on fact?

And beyond it—what?

Power to chain the universe….

Think, Garr Symm told himself. You’ve got to be rational. You’re a scientist. You’ve been trained as a scientist. This is their barrier, erected against you, against all humanoids, a million years ago. It isn’t real. It’s all in your mind.

“Do you want me to follow them down?” Ramar Chind asked.

Garr Symm envied the policeman. Naturally, Ramar Chind did not share his terror. You didn’t know the terror until you learned about proto-man; then the response seemed to be triggered in your brain, as if it had been passed to you through the genes of your ancestors, waiting a million years for release….

Fear, a guardian.

Of what? Garr Symm asked himself. Think of that, fool. Think of what it guards.

[p 117]
Power—

Teleportation or its equivalent.

Gone the subjective passage of hours in hyper-space.

Earned—if you were strong enough or brave enough to earn it—the ability to travel instantly from one humanoid world to another. Instantly. Perhaps from any one point on any humanoid world to any one point, precise, specific, exact, on another world.

To plunder.

Or assassinate.

Or control the lives of men, everywhere.

Sans ship.

Sans fear.

Sans the possibility of being caught or stopped.

Sweating, Garr Symm said: “Bring the Dog Star down after them, Ramar Chind.”

Ramsey smiled without humor. “What now, little lady?” he said mockingly.

“Shut up. Oh, shut up!”

“What are you going to do now?”

“I told you to shut up. I have to think.”

“I didn’t know a gorgeous

tri-di actress ever had to think.”

“Let me see those figures again,” Margot said.

Ramsey handed her the tapes from the Enterprise’s environment-checker.

Temperature: minus two hundred and twenty degrees Fahrenheit.

Atmosphere: none.

Gravity: eight-tenths Earth-norm.

“And we don’t have a spacesuit aboard,” Ramsey said.

“But it can’t be. It can’t. This is the home of proto-man. I know it is. But if I went out there I’d perish from cold in seconds and lack of air in minutes.”

“That’s right,” Ramsey said almost cheerfully. “So do I take the ship back up?”

“I hate you, Jason Ramsey. Oh, I hate you!” Margot cried. Then suddenly: “Wait! Wait a minute! What was that you were thinking? Tell me! You must tell me—”

Ramsey shook his head and tried to force the thoughts from his mind with doggerel. Ben Adam, he thought. Abou

Ben Adam, Humpty Dumpty, hurry, hurry, hurry, the only two headed get yours here the sum of the square of the sides is equal to the square of the hyper-space, no, mustn’t think that mimsy were the borogroves

and the momraths now what the heck did the momraths do anyhow absolute [p 118] zero is the temperature at which all molecular activity….

“What were you thinking, Ramsey?”

His mind was a labyrinth. There were thousands of discrete thoughts, of course. Millions of them, collected over a lifetime. But all at once he did not know his way through that labyrinth and his thoughts kept whirling back to the one Margot Dennison wanted as if, somehow, she could pluck it from his mind.

She stood before him, her brow furrowed, sweat beading her pretty face.

And she was winning, forcing the thought to take shape in Ramsey’s mind—

But if I went out there I’d perish from cold in seconds and lack of air in minutes.

Cold, came the known and unbidden thoughts to Ramsey’s struggling mind. And lack of air. Attributes of extension, of space, but measured by duration, by time. And since time does not exist in hyper-space, the vacuum out there and the terrible, killing cold, could have no effect on you. You could go out there perfectly protected from the lethal environment by the absence of the time dimension.

Margot smiled at him. “Thank you,” she said. “Thank you, Ramsey.”

He was about to speak, but she added: “And don’t give me that stuff about a power we shouldn’t tamper with. I’m going out there. Now.”

Ramsey nodded slowly. “I won’t stop you.”

“But just so you don’t get any ideas of stranding me here—Vardin. Vardin’s going with me.”

The Vegan girl looked at Ramsey mutely.

Ramsey said: “What makes you think I’ll let you take her?”

Margot smiled again. “The m.g. gun makes me think so.”

“The heck of it is, you’re not really bad, Margot. This thing’s got you, is all. You’re not essentially evil.”

“Thank you for the thrilling compliment. I’m delighted,” Margot said sarcastically.

“Vardin stays with me.”

Margot reminded him of the lethal m.g. gun by showing it to him, muzzle-first.

He laughed in her face. “Go ahead and shoot.”

She stared at him.

“There isn’t a lethal weapon’d do you any good here in a timeless continuum. Take an m.g. gun. It induces an [p 119] artificial breakdown of radioactive fuel in its chamber, firing an instantly lethal dose of radiation. But in order for radioactive breakdown to occur, time must pass. Even if it’s only milliseconds, as in the case of an m.g. gun. There aren’t any milliseconds on this world, Margot. There isn’t any time. So go ahead and pull the trigger.”

Margot frowned and pointed the gun to one side and fired.

Nothing happened. Margot almost looked as if her hard shell had been sundered by the impotence of the m.g. gun. She pouted. Her eyes gleamed moistly.

Then Ramsey said: “O.K. Let’s go.”

“What—what do you mean?”

“Out there. All of us.”

“But I thought you said—”

“Sure, I’m scared stiff. A normal man would be. It’s in our genes, according to your father. But I’m also a man. What the devil d’you think it was first got man out of his cave and started along the road to civilization and the stars? It was curiosity. Fear restraining him, and curiosity egging him on. Which do you think won in the end?”

“Oh, Ramsey, I could kiss you!”

“Go right ahead,” Ramsey said, and she did.

They opened the airlock. They went outside smiling.

But Vardin, who went with them, wasn’t smiling. There was sadness instead.

In cumbersome spacesuits, the five Irwadians made their way from the Dog Star to the Enterprise. Ramar Chind and his three policemen carried m.g. guns; Garr Symm was unarmed. Chind used a whorl-neutralizer to force the pattern of the lock on the outer door of the Enterprise’s airlock. Then the five of them plunged inside the ship.

The inner door was not closed.

The Enterprise was empty.

Garr Symm looked doubtfully at the gray murkiness behind them. Although the Dog Star stood out there less than a quarter of a mile away, they couldn’t see it through the murk.

“Where did they go?” Ramar Chind asked.

Symm waved vaguely behind them.

Chind and his men turned around.

Gritting his teeth against the fear which welled up like nausea from the pit of his stomach, Garr Symm went with them.

[p 120]
At that moment they all heard the music.

“You hear it?” Ramsey asked softly. His voice did not carry on the airless world, of course. But he spoke, and the words were understood, not merely by Margot, who could read his mind, but by Vardin as well.

“Music,” said Margot. “Isn’t it—beautiful?”

Ramsey nodded slowly. He could barely see Margot, although he held her hand. He could barely see Vardin although they stood hand in hand too. The music was un-Earthly, incapable of repetition, indescribably the loveliest sound he had ever heard. He wanted to sink down into the obscuring gray murk and weep and listen to the haunting, sad, lovely strains of sound forever.

“What can it possibly be?” Margot asked.

Surprisingly, it was Vardin who answered. “Music of the Spheres,” she said. “It’s a legend on Vega III, my world.”

“And on Earth,” Ramsey said.

Vardin told them: “On all worlds. And, like all such legends, it has a basis in reality. This is the basis.”

That didn’t sound like timid little Vardin at all. Ramsey listened in amazement. He thought he heard Vardin laugh.

Music. But didn’t the notes need the medium of time in which to be heard? How could they hear music here at all? Or were they hearing it? Perhaps it merely impinged on their minds, their souls, just as they were able to hear one another’s thoughts as words….

They’d never understand fully, Ramsey knew suddenly. Perhaps they could grasp a little of the nature of this place, a shadow here, the half-suggestion of the substance of reality there, a stillborn thought here, a note of celestial music there, the timeless legacy of proto-man, whatever proto-man was….

“The fog is lifting!” Vardin cried.

The fog was not lifting.

Then it was.

Ramsey would never forget that. Vardin had spoken while the dense gray murk enveloped them completely.

Then it began to grow tenuous.

As if Vardin’s words had made it so. Little Vardin, shy, frightened Vardin, suddenly, inexplicably, the strongest, surest one among them….

The sky, white and [p 121] dazzling, glistened. The gray murk glistened too, a hundred yards off in all directions, like a wall of polished glass surrounding them.

In the very middle of the bell-jar of visibility granted them all at once, stood a black rectangular object.

“The teleporter!” Margot cried. “The matter-transmitter! I know it is. I know it is!”

Ramsey stood waiting breathlessly.

No, he realized abruptly, not breathlessly. You couldn’t say breathlessly.

For Ramsey had not breathed, not once, since they left the Enterprise.

You didn’t breathe on a timeless world. You merely—somehow—existed.

“It’s opening!” Margot cried.

The black rectangle, ominously coffin-shaped, was indeed opening.

“The matter transmitter,” Margot said a second time. “The secret of proto-man, of our ancestors who colonized all the worlds of space with it, instantly, at the same cosmic moment. Think of what it means, Ramsey, can you? Instantaneous travel, anywhere, without the need for energy since energy cannot be used here, without the passage of time since time does not exist here.” She stood transfixed, looking at
