The Space Pup arrowed steadily toward Pluto. From the engine room came the subdued hum of the geosectors. The vision plate looked out on ebon space with its far-flung way posts of tiny, steely stars. The needle was climbing up near the thousand-miles-a-second mark.

Caroline Martin leaned forward in her chair and stared out at the vastness that stretched eternally ahead. "I could stay and watch forever," she exulted.

Gary, lounging back in the pilot's seat, said quietly:

"I've been thinking about that name of yours. It seems to me I've heard it somewhere. Read it in a book.”

She glanced at him swiftly and then stared out into space.

"Perhaps you have," she said finally.

There was a silence, unbroken except by the humming of the geosectors.

The girl turned back to Gary, chin cupped in her hands. "Probably you have read about me;" she said. 'Perhaps the name of Caroline Martin is mentioned in your histories. You see, I was a member of the old Mars-Earth Research commission during the war with Jupiter. I was so proud of the appointment.

Just four years out of school and I was trying so hard to get a good job in some scientific research work. I wanted to earn money to go back to school again.”

"I'm beginning to remember now," said Gary, "but there must be something wrong. The histories say you were a traitor. They say you were condemned to death.”

"I was a traitor," she said and there was a thread of ancient bitterness in the words she spoke. "I refused to turn over a discovery I made, a discovery that would have won the war. It also would have wrecked the solar system. I told them so, but they were men at war. They were desperate men.

We were losing then.”

"We never did win, really," Gary told her.

"They condemned me to space," she said. "They put me in that shell you found me in and a war cruiser towed it out to Pluto's orbit and cut it loose. It was an old condemned craft, its machinery outmoded. They ripped out the rockets and turned it into a prison for me.”

She made a gesture of silence at the shocked look on their faces.

"The histories don't tell that part of it," said Herb.

"They probably suppressed it," she said. "Men at war will do things that no sane man will do. They would not admit in peace the atrocities that they committed in the time of battle. They put the laboratory in the control room as a final ironic jest. So I could carry out my research, they said.

Research, they told me, I'd not need to turn over to them.”

"Would your discovery have wrecked the system?”

Gary asked.

"Yes," she said, "it would have. That's why I refused to give it to the military board. For that they called me traitor. I think they hoped to break me. I think they thought up to the very last that, faced with exile in space, I would finally crack and give it to them.”

"When you didn't," Herb said, "they couldn't back down. They couldn't afford to let you call their bluff.”

"They never found your notes," said Gary.

She tapped her forehead with a slender finger. "My notes were here," she said.

He looked amazed.

"And still are," she said.

"But how did you get the drugs to carry out your suspended animation?" Gary asked.

She waited for long minutes.

"That's the part I hate to think about," she said. "The part that's hard to think about. I worked with a young man. About my age, then. He must be dead these many years.”

She stopped and Gary could see that she was trying to marshal in her mind what next to say.

"We were in love," she said. "Together we discovered the suspended animation process. We had worked on it secretly for months and were ready to announce it when I was taken before the military tribunal. They never let me see him after that. I was allowed no visitors.

"Out in space, after the war cruiser left, I almost went insane. I invented all sorts of tasks to do. I arranged and rearranged my chemicals and apparatus and then one day I found the drugs, skillfully hidden in a box of chemicals. Only one person in the world besides myself knew about them. I found the drugs and two hypodermic syringes.”

Gary's pipe had gone out and now he relit it. The girl went on.

"I knew it would be a gamble," she said. "I knew he intended that I should take that gamble. Maybe he had a wild scheme of coming out and hunting for me. Maybe something happened and he couldn't come. Maybe he tried and failed. Maybe the war… got him. But he had given me a chance, a desperate chance to beat the fate the military court had set for me. I removed the steel partition in the engine room to make the tank. That took many weeks.

I etched the copper plate. I went outside on the shell and etched the lines beside the lock. I'm afraid that wasn't a very good job.”

"And then," said Herb, "you put yourself to sleep.”

"Not exactly sleep," she said. "Because my brain still worked. I thought and thought for almost a thousand years. My mind set up problems and worked them out. I developed a flair for pure deduction, since my mind was the only thing left for me to work with. I believe I even developed telepathic powers.”

"You mean," asked Herb, "that you can read our thoughts?”

She nodded, then hastened on. "But I wouldn't," she said. "I wouldn't do that to my friends. I knew when Gary first came to the shell. I read the wonder and amazement in his thoughts. I was so afraid he'd go away and leave me alone again. I tried to talk to him with my thoughts, but he was so upset that he couldn't understand.”

Gary shook his head. "Anyone would have been upset," he said.

"But," exploded Herb, "think of the chances that you took. It was just pure luck we found you. Your drug wouldn't have held up forever. Another few thousand years, perhaps, but scarcely longer than that. Then there would be the chance that the atmosphere generators might have failed. Or that a big meteor, or even a small one, for that matter, might have come along. There were a thousand things that could have happened.”

She agreed with him. "It was a long chance. I knew it was. But there was no other way. I could have just sat still and done nothing or gone crazy, grown old and died in loneliness.”

She was silent for a moment.

"It would have been easy," she said then, "if I hadn't made that one mistake.”

"Weren't you frightened?" Gary asked.

Her eyes widened slightly and she nodded.

"I heard voices," she said. "Voices coming out of space, out of the void that lies between the galaxies. Things talking over many light-years with one another. Things to which the human race, intellectually, would appear mere insects. At first I was frightened, frightened at the things they said, at the horrible hints I sensed in the things I couldn't understand.

Then, growing desperate, I tried to talk back to them, tried to attract their attention. I wasn't afraid of them any more and I thought that they might help. I didn't care much what happened any more just so someone, or something, would help me. Even take notice of me. Anything to let me know that I wasn't all alone.”

Gary lit his pipe again and silence fell for just a space. "Voices," said Herb.

They all stared out at that darkness that hemmed them in. Gary felt the hairs bristle at the nape of his neck. Some cold wind from far away had brushed against his face, an unnamable terror out of the cosmos reaching out for him, searching for him with dirty-taloned thoughts. Things that hurled pure thought across the deserts of emptiness that lay between the galaxies.

"Tell me," said Caroline, and her voice, too, seemed to come from far away, "how did the war come out?”

"The war?" asked Gary. Then he understood.

"Oh, the war," he said. "Why, Earth and Mars finally won out. Or so the histories claim. There was a battle out near Ganymede and both fleets limped home badly beaten up. The Jovians went back to Jupiter, the Earth-Mars fleet pulled into Sandebar on Mars. For months the two inner planets built up their fleets and strengthened home defenses. But the Jovians never came out again and our fleets didn't dare carry the war to the enemy. Even today we haven't developed a ship that dares go into Jupiter's atmosphere. Our geosectors might take us there and bring us back, but you can't use them near a planetary body. They work on the principle of warping space…”

"Warping space?" asked the girl, suddenly sitting upright.

"Sure," said Gary. "Anything peculiar about it?" "No," she said, "I don't suppose there is.”

Then: "I wouldn't exactly call that a victory.”

"That's what the histories call it." Gary shrugged. "They claim we run the Jovians to cover and they've been afraid to come out ever since. Earth and Mars have taken over Jupiter's moons and colonized them, but to this day no one has sighted a Jovian or a Jovian ship. Not since that day back in 5980.

"It's just one of them things," Herb decided for them.

The girl was staring out at space again. Hungry for seeing, hungry for living, but with the scars of awful memories etched into her brain.

Gary shivered to himself. Alone, she had taken her gamble and had won. Won against time and space and the brutality of man and the great indifference of the mighty sweep of stars.

What had she thought of during those long years? What problems had she solved? What kind of a person could she be, with her twenty-year-old body and her thousand-year-old brain?

Gary nursed the hot bowl of his pipe between his hands, studying the outline of her head against the vision-plate. Square chin, high forehead, the braided strands wrapped around her head.

What was she thinking now? Of that lover who now would be forgotten dust?

Of how he might have tried to find her, of how he might have searched through space and failed? Or was she thinking of the voices… the voice talking back and forth across the gulfs of empty space?

The spacewriter, sitting in its own dark corner, broke into a gibbering chatter.

Gary sprang to his feet.

"Now what?" he almost shouted.

The chattering ceased and the machine settled into the click-clack of its message.

Gary hurried forward. The other two pressed close behind, looking over his shoulder.

NELSON, ABOARD SPACE PUP, NEARING PLUTO. KINGSLEY REPORTS RECEIVING STRANGE MESSAGES FROM SOMEWHERE OUT OF THE SOLAR SYSTEM. UNABLE, OR UNWILLING, TO GUESS AT SOURCE. REFUSES TO GIVE CIRCUMSTANCES UNDER WHICH MESSAGES WERE RECEIVED OR CONTEXT OF THEM, IF IN FACT HE KNOWS CONTEXT. URGENT THAT YOU GET STATEMENT FROM HIM SOONEST. REGARDS. EVENING ROCKET.

The machine's stuttering came to an end.’

The three stared at one another.

"Messages," said Herb. "Messages out of space.”

Gary shook his head. He stole a swift glance at the girl and her face seemed pale. Perhaps she was remembering.
