“But with an inactive strain,” said Bliss.
“Still, it can be made active. They had a method. What is the method?”
Bliss shrugged. “Hiroko said the virus, left inactive, would eventually die in a body unadapted to it-as yours is.”
“Yes?” said Trevize angrily. “How does she know that? For that matter, how do I know that Hiroko’s statement wasn’t a self-consoling lie? And isn’t it possible that the method of activation, whatever it is, might not be duplicated naturally? A particular chemical, a type of radiation, a-a-who knows what? I may sicken suddenly, and then the three of you would die, too. Or if it happens after we have reached a populated world, there may be a vicious pandemic which fleeing refugees would carry to other worlds.”
He looked at Bliss. “Is there something you can do about it?”
Slowly, Bliss shook her head. “Not easily. There are parasites making up Gaia-microorganisms, worms. They are a benign part of the ecological balance. They live and contribute to the world consciousness, but never overgrow. They live without doing noticeable harm. The trouble is, Trevize, the virus that affects you is not part of Gaia.”
“You say ‘not easily,” ‘said Trevize, frowning. “Under the circumstances, can you take the trouble to do it even though it might be difficult? Can you locate the virus in me and destroy it? Can you, failing that, at least strengthen my defenses?”
“Do you realize what you ask, Trevize? I am not acquainted with the microscopic flora of your body. I might not easily tell a virus in the cells of your body from the normal genes inhabiting them. It would be even more difficult to distinguish between viruses your body is accustomed to and those with which Hiroko infected you. I will try to do it, Trevize, but it will take time and I may not succeed.”
“Take time,” said Trevize. “Try.”
“Certainly,” said Bliss.
Pelorat said, “If Hiroko told the truth, Bliss, you might be able to find viruses that seem to be already diminishing in vitality, and you could accelerate their decline.”
“I could do that,” said Bliss. “It is a good thought.”
“You won’t weaken?” said Trevize. “You will have to destroy precious bits of life when you kill those viruses, you know.”
“You are being sardonic, Trevize,” said Bliss coolly, “but, sardonic or not, you are pointing out a true difficulty. Still, I can scarcely fail to put you ahead of the virus. I will kill them if I have the chance, never fear. After all, even if I fail to consider you”-and her mouth twitched as though she were repressing a smile-” then certainly Pelorat and Fallom are also at risk, and you might feel more confidence in my feeling for them than in my feeling for you. You might even remember that I myself am at risk.”
“I have no faith in your self-love,” muttered Trevize. “You’re perfectly ready to give up your life for some high motive. I’ll accept your concern for Pelorat, however.” Then, he said, “I don’t hear Fallom’s flute. Is anything wrong with her?”
“No,” said Bliss. “She’s asleep. A perfectly natural sleep that I had nothing to do with. And I would suggest that, after you work out the Jump to the star we think is Earth’s sun, we all do likewise. I need it badly and I suspect you do, too, Trevize.”
“Yes, if I can manage.-You were right, you know, Bliss.”
“About what, Trevize?”
“About Isolates. New Earth was not a paradise, however much it might have seemed like one. That hospitality-all that outgoing friendliness at first-was to put us off our guard, so that one of us might be easily infected. And all the hospitality afterward, the festivals of this and that, were designed to keep us there till the fishing fleet returned and the activation could be carried through. And it would have worked but for Fallom and her music. It might be you were right there, too.”
“About Fallom?”
“Yes. I didn’t want to take her along, and I’ve never been happy with her being on the ship. It was your doing, Bliss, that we have her here and it was she who, unwittingly, saved us. And yet-”
“And yet what?”
“Despite that, I’m still uneasy at Fallom’s presence. I don’t know why.”
“If it will make you feel better, Trevize, I don’t know that we can lay all the credit at Fallom’s feet. Hiroko advanced Fallom’s music as her excuse for committing what the other Alphans would surely consider to be an act of treason. She may even have believed this, but there was something in her mind in addition, something that I vaguely detected but could not surely identify, something that perhaps she was ashamed to let emerge into her conscious mind. I am under the impression that she felt a warmth for you, and would not willingly see you die, regardless of Fallom and her music.”
“Do you really think so?” said Trevize, smiling slightly for the first time since they had left Alpha.
“I think so. You must have a certain proficiency at dealing with women. You persuaded Minister Lizalor to allow us to take our ship and leave Comporellon, and you helped influence Hiroko to save our lives. Credit where it’s due.”
Trevize smiled more broadly. “Well, if you say so.-On to Earth, then.” He disappeared into the pilot-room with a step that was almost jaunty.
Pelorat, lingering behind, said, “You soothed him after all, didn’t you, Bliss?”
“No, Pelorat, I never touched his mind.”
“You certainly did when you pampered his male vanity so outrageously.”
“Entirely indirect,” said Bliss, smiling.
“Even so, thank you, Bliss.”
86.
AFTER THE JUMP, the star that might well be Earth’s sun was still a tenth of a parsec away. It was the brightest object in the sky by far, but it was still no more than a star.
Trevize kept its light filtered for ease of viewing, and studied it somberly.
He said, “There seems no doubt that it is the virtual twin of Alpha, the star that New Earth circles. Yet Alpha is in the computer map and this star is not. We don’t have a name for this star, we aren’t given its statistics, we lack any information concerning its planetary system, if it has one.”
Pelorat said, “Isn’t that what we would expect if Earth circles this sun? Such a blackout of information would fit with the fact that all information about Earth seems to have been eliminated.”
“Yes, but it could also mean that it’s a Spacer world that just happened not to be on the list on the wall of the Melpomenian building. We can’t be altogether sure that that list was complete. Or this star could be without planets and therefore perhaps not worth listing on a computer map which is primarily used for military and commercial purposes.-Janov, is there any legend that tells of Earth’s sun being a mere parsec or so from a twin of itself.”
Pelorat shook his head. “I’m sorry, Golan, but no such legend occurs to me. There may be one, though. My memory isn’t perfect. I’ll search for it.”
“It’s not important. Is there any name given to Earth’s sun?”
“Some different names are given. I imagine there must be a name in each of the different languages.”
“I keep forgetting that Earth had many languages.”
“It must have had. It’s the only way of making sense out of many of the legends.”
Trevize said peevishly, “Well, then, what do we do? We can’t tell anything about the planetary system from this distance, and we have to move closer. I would like to be cautious, but there’s such a thing as excessive and unreasoning caution, and I see no evidence of possible danger. Presumably anything powerful enough to wipe the Galaxy clean of information about Earth may be powerful enough to wipe us out even at this distance if they seriously did not wish to be located, but nothing’s happened. It isn’t rational to stay here forever on the mere possibility that something might happen if we move closer, is it?”
Bliss said, “I take it the computer detects nothing that might be interpreted as dangerous.”
“When I say I see no evidence of possible danger,
it’s the computer I’m relying on. I certainly can’t see anything with the unaided eye. I wouldn’t expect to.”
“Then I take it you’re just looking for support in making what you consider a risky decision. All right, then. I’m with you. We haven’t come this far in order to turn back for no reason, have we?”
“No,” said Trevize. “What do you say, Pelorat?”
Pelorat said, “I’m willing to move on, if only out of curiosity. It would be unbearable to go back without knowing if we have found Earth.”
“Well, then,” said Trevize, “we’re all agreed.”
“Not all,” said Pelorat. “There’s Fallom.”
Trevize looked astonished. “Are you suggesting we consult the child? Of what value would her opinion be even if she had one? Besides, all she would want would be to get back to her own world.”
“Can you blame her for that?” asked Bliss warmly.
And because the matter of Fallom had arisen, Trevize became aware of her flute, which was sounding in a rather stirring march rhythm.
“Listen to her,” he said. “Where has she ever heard anything in march rhythm?”
“Perhaps Jemby played marches on the flute for her.”
Trevize shook his head. “I doubt it. Dance rhythms, I should think, lullabies.-Listen, Fallom makes me uneasy. She learns too quickly.”
“I help her,” said Bliss. “Remember that. And she’s very intelligent and she has been extraordinarily stimulated in the time she’s been with us. New sensations have flooded her mind. She’s seen space, different worlds, many people, all for the first time.”
Fallom’s march music grew wilder and more richly barbaric.
Trevize sighed and said, “Well, she’s here, and she’s producing music that seems to breathe optimism, and delight in adventure. I’ll take that as her vote in favor of moving in more closely. Let us do so cautiously, then, and check this sun’s planetary system.”
“If any,” said Bliss.
Trevize smiled thinly. “There’s a planetary system. It’s a bet. Choose your sum.”
87.
“YOU LOSE,” SAID Trevize abstractedly. “How much money did you decide to bet?”
“None. I never accepted the wager,” said Bliss.
“Just as well. I wouldn’t like to accept the money, anyway.”
They were some 10 billion kilometers from the sun. It was still star-like, but it was nearly 1/4,000 as bright as the average sun would have been when viewed from the surface of a habitable planet.
“We can see two planets under magnification, right now,” said Trevize. “From their measured diameters and from the spectrum of the reflected light, they are clearly gas giants.”
The ship was well outside the planetary plane, and Bliss and Pelorat, staring over Trevize’s shoulder at the viewscreen, found themselves looking at two tiny crescents of greenish light. The smaller was in the somewhat thicker phase of the two.
Trevize said, “Janov! It is correct, isn’t it, that Earth’s sun is suppose to have four gas giants.”
“According to the legends. Yes,” said Pelorat.
“The nearest of the four to the sun is the largest, and the second nearest has rings. Right?”
“Large prominent rings, Golan. Yes. Just the same, old chap, you have to allow for exaggeration in the telling and retelling of a legend. If we should not find a planet with an extraordinary ring system, I don’t think we ought to let that count seriously against this being Earth’s star.”
“Nevertheless, the two we see may be the farthest, and the two nearer ones may well be on the other side of the sun and too far. to be easily located against the background of stars. We’ll have to move still closer-and beyond the sun to the other side.”
“Can that be done in the presence of the star’s nearby mass?”
“With reasonable caution, the computer can do it, I’m sure. If it judges the danger to be too great, however, it will refuse to budge us, and we can then move in cautious, smaller steps.”
His mind directed the computer-and the starfield on the viewscreen changed. The star brightened sharply and then moved off the viewscreen as the computer, following directions, scanned the sky for another gas giant. It did so successfully.
All three onlookers stiffened and stared, while Trevize’s mind, almost helpless with astonishment, fumbled at the computer to direct further magnification.
“Incredible,” gasped Bliss.
88.
A GAS GIANT was in view, seen at an angle that allowed most of it to be sunlit. About it, there curved a broad and brilliant ring of material, tipped so as to catch the sunlight on the side being viewed. It was brighter than the planet itself and along it, one third of the way in toward the planet, was a narrow, dividing line.
Trevize threw in a request for maximum enhancement and the ring became ringlets, narrow and concentric, glittering in the sunlight. Only a portion of the ring system was visible on the viewscreen and the planet itself had moved off. A further direction from Trevize and one corner of the screen marked itself off and showed, within itself, a miniature of the planet and rings under lesser magnification.
“Is that sort of thing common?” asked Bliss, awed.
“No,” said Trevize. “Almost every gas giant has rings of debris, but they tend to be faint and narrow. I once saw one in which the rings were narrow, but quite bright. But I never saw anything like this; or heard of it, either.”
Pelorat said, “That’s clearly the ringed giant the legends speak of. If this is really unique-”
“Really unique, as far as I know, or as far as the computer knows,” said Trevize.
“Then this must be the planetary system containing Earth. Surely, no one could invent such a planet. It would have had to have been seen to be described.”
Trevize said, “I’m prepared to believe just about anything your legends say now. This is the sixth planet and Earth would be the third?”
“Right, Golan.”
“Then I would say we were less than 1.5 billion kilometers from Earth, and we haven’t been stopped. Gaia stopped us when we approached.”
Bliss said, “You were closer to Gaia when you were stopped.”
“Ah,” said Trevize, “but it’s my opinion Earth is more powerful than Gaia, and I take this to be a good sign. If we are not stopped, it may be that Earth does not object to our approach.”
“Or that there is no Earth,” said Bliss.
“Do you care to bet this time?” asked Trevize grimly.
“What I think Bliss means,” put in Pelorat, “is that Earth may be radioactive as everyone seems to think, and that no one stops us because there is no life on the Earth.”
“No,” said Trevize violently. “I’ll believe everything that’s said about Earth, but that. We’ll just close in on Earth and see for ourselves. And I have the feeling we won’t be stopped.”
89.
THE GAS GIANTS were well behind. An asteroid belt lay just inside the gas giant nearest the sun. (That gas giant was the largest and most massive, just as the legends said.)
Inside the asteroid belt were four planets.
Trevize studied them carefully. “The third is the largest. The size is appropriate. and the distance from the sun is appropriate. It could be habitable.”
Pelorat caught what seemed to be a note of uncertainty in Trevize’s words.
He said, “Does it have an atmosphere?”
“Oh yes,” said Trevize. “The second, third, and fourth planets all have atmospheres. And, as in the old children’s tale, the second’s is too dense, the fourth’s is not dense enough, but the third’s is just right.”
“Do you think it might be Earth, then?”
“Think?” said Trevize almost explosively. “I don’t have to think. It is Earth. It has the giant satellite you told me of.”
“It has?” And Pelorat’s face broke into a wider smile than any that Trevize had ever seen upon it.
“Absolutely! Here,
look at it under maximum magnification.”
Pelorat saw two crescents, one distinctly larger and brighter than the other.
“Is that smaller one the satellite?” he asked.
“Yes. It’s rather farther from the planet than one might expect but it’s definitely revolving about it. It’s only the size of a small planet; in fact, it’s smaller than any of the four inner planets circling the sun. Still, it’s large for a satellite. It’s at least two thousand kilometers in diameter, which makes it in the size range of the large satellites that revolve about gas giants.”
“No larger?” Pelorat seemed disappointed. “Then it’s not a giant satellite?”
“Yes, it is. A satellite with a diameter of two to three thousand kilometers that is circling an enormous gas giant is one thing. That same satellite circling a small, rocky habitable planet is quite another. That satellite has a diameter over a quarter that of Earth. Where have you heard of such near-parity involving a habitable planet?”
Pelorat said timidly, “I know very little of such things.”
Trevize said, “Then take my word for it, Janov. It’s unique. We’re looking at something that is practically a double planet, and there are few habitable planets that have anything more than pebbles orbiting them.-Janov, if you consider that gas giant with its enormous ring system in sixth place, and this planet with its enormous satellite in third-both of which your legends told you about, against all credibility, before you ever saw them-then that world you’re looking at must be Earth. It cannot conceivably be anything else. We’ve found it, Janov; we’ve found it.”
90.
THEY WERE ON the second day of their coasting progress toward Earth, and Bliss yawned over the dinner meal. She said, “It seems to me we’ve spent more time coasting toward and away from planets than anything else. We’ve spent weeks at it, literally.”
“Partly,” said Trevize, “that’s because Jumps are dangerous too close to a star. And in this case, we’re moving very slowly because I do not wish to advance into possible danger too quickly.”
