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 repet.i.tion, 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 dazzling, glistened. The gray murk glistened too, a hundred yards off in all directions, like a wall of polished gla.s.s 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 s.p.a.ce 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 pa.s.sage of time since time does not exist here." She stood transfixed, looking at the black box. The lid had lifted at right angles to the rest of the box.

Margot said, in the whisper of an awed thought: "Who controls it controls the galaxy...."

And she walked toward the box.

At that moment Ramsey had a vision. He saw--or thought he saw--Margot Dennison in the costume she had worn when they first met. She stood, eyes wide, fearful, expectant, before a chess-board. The pieces seemed to be s.p.a.ceships. It was a perfectly clear vision, but it was the only such vision Ramsey had ever been vouchsafed in his life. He was no mystic. He did not know what to make of it.

Playing chess with Margot was--proto-man.

Ramsey only saw his hand.

A hand perhaps five million years old.

He blinked. The vision persisted, superimposed over Margot's figure as she walked toward the box.

A game, he thought. Because we don't understand it. Not that kind of power. Not the power a matter-transmitter would give. A cosmic game on a chess-board which wasn't quite a chess-board, with a creature who had never lived as we know life and so could never die....

With the future of the galaxy hanging in the balance. Life or death for man hanging on a slim thread, because man wasn't ready for matter-transmission, couldn't hope to use it wisely, would use it perhaps for war, transmitting lethal weapons, thermonuclear, world-destroying weapons, instantly through s.p.a.ce, for delivery anywhere, negating time....

Death hovered.

"Wait!" Ramsey called, and ran forward.

Just then five new figures, s.p.a.ce-suited, appeared under the gleaming dome.

"Stop that woman!" a voice which Ramsey should not have been able to hear but which he somehow heard perfectly cried. "Stop her!"

M.g. guns were raised, fired.

Without effect.

Three of the s.p.a.cesuited figures ran after Margot as the voice repeated: "Stop her! The box is mine, mine!"

It was Garr Symm's voice.

Ramsey did not know if he should stop Margot himself, or fight Symm's men. Although they couldn't use their weapons on this world, they could still hurt--possibly even kill--Margot. Ramsey turned and waited for them.

The strange, mystic vision was gone. He saw only three s.p.a.ce-suited figures, saw Margot walking steadily toward the box. Either she was moving very slowly or the box retreated or it was further away than it had looked at first. For she hadn't reached it yet.

Ramsey met the s.p.a.ce-suited figures head-on.

There were three of them, but they were awkward in their suits, c.u.mbersome, incapable of quick responses.

Ramsey hit the first one in the belly and darted back. His fist felt contact with the soft bulk of the insulined suit, then with the harder bulk of the man. He struck again, harder this time.

The scaly green face of the Irwadi within the s.p.a.ce-suit grimaced with pain. He doubled over and fell, his helmet shattering against the ground at Ramsey's feet.
