Tommy Dort hesitated. Then he shrugged and tapped expertly upon the coder. More improbable noises.
The alien skipper seemed to receive the message. He made a gesture which was wryly assenting. The decoder on the Llanvabon hummed to itself and word-cards dropped into the message frame. Tommy said dispassionately :
“He says, sir, ‘That is all very well, but is there any way for us to let each other go home alive? I would be happy to hear of such a way if you can contrive one. At the moment it seems to me that one of us must be killed.”
IV.
The atmosphere was of confusion. There were too many questions to be answered all at once. Nobody could answer any of them. And all of them had to be answered.
The Llanvabon could start for home. The alien ship might or might not be able to multiply the speed of light by one more unit than the Earth vessel. If it could, the Llanvabon would get close enough to Earth to reveal its destination—and then have to fight. It might or might not win. Even if it did win, the aliens might have a communication system by which the Llanvabon’s destination might have been reported to the aliens’ home planet before battle was joined. But the Llanvabon might lose in such a fight. If she was to be destroyed, it would be better to be destroyed here, without giving any clue to where human beings might be found by a forewarned, forearmed alien battle fleet.
The black ship was in exactly the same predicament. It, too, could start for home. But the Llanvabon might be faster, and an overdrive field can be trailed, if you set to work on it soon enough. The aliens, also, would not know whether the Llanvabon could report to its home base without returning. If the alien was to be destroyed, it also would prefer to fight it out here, so that it could not lead a probable enemy to its own civilization.
Neither ship, then, could think of flight The course of the Llanvabon into the nebula might be known to the black ship, but it had been the end of a logarithmic curve, and the aliens could not know its properties. They could not tell from that from what direction the Earth ship had started. As of the moment, then, the two ships were even. But the question was and remained, “What now?”
There was no specific answer. The aliens traded information for information—and did not always realize what information they gave. The humans traded information for information—and Tommy Dort sweated blood in his anxiety not to give any clue to the whereabouts of Earth.
The aliens saw by infrared light, and the vision plates and scanners in the robot communication-exchange had to adapt their respective images up and down an optical octave each, for them to have any meaning at all. It did not occur to the aliens that their eyesight told that their sun was a red dwarf, yielding light of greatest energy just below the part of the spectrum visible to human eyes. But after that fact was realized on the Llanvabon, it was realized that the aliens, also, should be able to deduce the Sun’s spectral type by the light to which men’s eyes were best adapted.
There was a gadget for the recording of short-wave trains which was as casually in use among the aliens as a sound-recorder is among men. The humans wanted that, badly. And the aliens were fascinated by the mystery of sound. They were able to perceive noise, of course, just as a man’s palm will perceive infrared light by the sensation of heat it produces, but they could no more differentiate pitch or tone-quality than a man is able to distinguish between two frequencies of heat-radiation even half an octave apart. To them, the human science of sound was a remarkable discovery. They would find uses for noises which humans had never imagined—if they lived.
But that was another question. Neither ship could leave without first destroying the other. But while the flood of information was in passage, neither ship could afford to destroy the other. There was the matter of the outer coloring of the two ships. The Llanvabon was mirror-bright exteriorly. The alien ship was dead-black by visible light. It absorbed heat to perfection, and should radiate it away again as readily. But it did not. The black coating was not a “black body” color or lack of color. It was a perfect reflector of certain infrared wave lengths while simultaneously it fluoresced in just those wave bands. In practice, it absorbed the higher frequencies of heat, converted them to lower frequencies it did not radiate—and stayed at the desired temperature even in empty space.
Tommy Dort labored over his task of communications. He found the alien thought-processes not so alien that he could not follow them. The discussion of technics reached the matter of interstellar navigation. A star map was needed to illustrate the process. It would have been logical to use a star map from the chart room—but from a star map one could guess the point from which the map was projected. Tommy had a map made specially, with imaginary but convincing star images upon it. He translated directions for its use by the coder and decoder. In return, the aliens presented a star map of their own before the visiplate. Copied instantly by photograph, the Nav officers labored over it, trying to figure out from what spot in the galaxy the stars and Milky Way would show at such an angle. It baffled them.
It was Tommy who realized finally that the aliens had made a special star map for their demonstration too, and that it was a mirror-image of the faked map Tommy had shown them previously.
Tommy could grin, at that. He began to like these aliens. They were not human, but they had a very human sense of the ridiculous. In course of time Tommy essayed a mild joke. It had to be translated into code numerals, these into quite cryptic groups of short-wave, frequency-modulated impulses, and these went to the other ship and into heaven knew what to become intelligible. A joke which went through such formalities would not seem likely to be funny. But the aliens did see the point.
There was one of the aliens to whom communication became as normal a function as Tommy’s own code-handlings. The two of them developed a quite insane friendship, conversing by coder, decoder and short-wave trains. When technicalities in the official messages grew too involved, that alien sometimes threw in strictly nontechnical interpolations akin to slang. Often, they cleared up the confusion. Tommy, for no reason whatever, had filed a code-name of “Buck” which the decoder picked out regularly when this particular operator signed his own symbol to a message.
In the third week of communication, the decoder suddenly presented Tommy with a message in the message frame.
You are a good guy. It is too bad we have to kill each other.—Buck.
Tommy had been thinking much the same thing. He tapped off the rueful reply:
We can’t see any way out of it. Can you?
There was a pause, and the message frame filled up again.
If we could believe each other, yes. Our skipper would like it. But we can’t believe you, and you can’t believe us. We’d trail you home if we got a chance, and you’d trail us. But we feel sorry about it.—Buck.
Tommy Dort took the messages to the skipper.
“Look here, sir!” he said urgently. “These people are almost human, and they’re likable cusses.”
The skipper was busy about his important task of thinking things to worry about, and worrying about them. He said tiredly:
“They’re oxygen breathers. Their air is twenty-eight per cent oxygen instead of twenty, but they could do very well on Earth. It would be a highly desirable conquest for them. And we still don’t know what weapons they’ve got or what they can develop. Would you tell them how to find Earth?”
“N-no,” said Tommy, unhappily.
“They probably feel the same way,” said the skipper dryly. “And if we did manage to make a friendly contact, how long would it stay friendly? If their weapons were inferior to ours, they’d feel that for their own safety they had to improve them. And we, knowing they were planning to revolt, would crush them while we could—for our own safety! If it happened to be the other way about, they’d have to smash us before we could catch up to them.”
Tommy was silent, but he moved restlessly.
“If we smash this black ship and get home,” said the skipper, “Earth Government will be annoyed
if we don’t tell them where it came from. But what can we do? We’ll be lucky enough to get back alive with our warning. It isn’t possible to get out of those creatures any more information than we give them, and we surely won’t give them our address! We’ve run into them by accident. Maybe—if we smash this ship—there won’t be another contact for thousands of years. And it’s a pity, because trade could mean so much! But it takes two to make a peace, and we can’t risk trusting them. The only answer is to kill them if we can, and if we can’t, to make sure that when they kill us they’ll find out nothing that will lead them to Earth. I don’t like it,” added the skipper tiredly, “but there simply isn’t anything else to do!”
V.
On the Llanvabon, the technicians worked frantically in two divisions. One prepared for victory, and the other for defeat. The ones working for victory could do little. The main blasters were the only weapons with any promise. Their mountings were cautiously altered so that they were no longer fixed nearly dead ahead, with only a 50 traverse. Electronic controls which followed a radio-locator master-finder would keep them trained with absolute precision upon a given target regardless of its maneuverings. More; a hitherto unsung genius in the engine room devised a capacity-storage system by which the normal full-output of the ship’s engines could be momentarily accumulated and released in surges of stored power far above normal. In theory, the range of the blasters should be multiplied and their destructive power considerably stepped up. But there was not much more that could be done.
The defeat crew had more leeway. Star charts, navigational instruments carrying telltale notations, the photographic record Tommy Dort had made on the six months’ journey from Earth, and every other memorandum offering clues to Earth’s position, were prepared for destruction. They were put in sealed files, and if any one of them was opened by one who did not know the exact, complicated process, the contents of all the files would flash into ashes and the ashes be churned past any hope of restoration. Of course, if the Llanvabon should be victorious, a carefully not-indicated method of reopening them in safety would remain.
There were atomic bombs placed all over the hull of the ship. If its human crew should be killed without complete destruction of the ship, the atomic-power bombs should detonate if the Llanvabon were brought alongside the alien vessel. There were no ready-made atomic bombs on board, but there were small spare atomic-power units on board. It was not hard to trick them so that when they were turned on, instead of yielding a smooth flow of power they would explode. And four men of the earth ship’s crew remained always in spacesuits with closed helmets, to fight the ship should it be punctured in many compartments by an unwarned attack.
Such an attack, however, would not be treacherous. The alien skipper had spoken frankly. His manner was that of one who wryly admits the uselessness of lies. The skipper and the Llanvabon, in turn, heavily admitted the virtue of frankness. Each insisted—perhaps truthfully—that he wished for friendship between the two races. But neither could trust the other not to make every conceivable effort to find out the one thing he needed most desperately to conceal—the location of his home planet. And neither dared believe that the other was unable to trail him and find out. Because each felt it his own duty to accomplish that unbearable—to the other—act, neither could risk the possible extinction of his race by trusting the other. They must fight because they could not do anything else.
They could raise the stakes of the battle by an exchange of information beforehand. But there was a limit to the stake either would put up. No information on weapons, population, or resources would be given by either. Not even the distance of their home bases from the Crab Nebula would be told. They exchanged information, to be sure, but they knew a battle to the death must follow, and each strove to represent his own civilization as powerful enough to give pause to the other’s ideas of possible conquest—and thereby increased its appearance of menace to the other, and made battle more unavoidable.
It was curious how completely such alien brains could mesh, however. Tommy Dort, sweating over the coding and decoding machines, found a personal equation emerging from the at first stilted arrays of word-cards which arranged themselves. He had seen the aliens only in the vision screen, and then only in light at least one octave removed from the light they saw by. They, in turn, saw him very strangely, by transposed illumination from what to them would be the far ultraviolet. But their brains worked alike. Amazingly alike. Tommy Dort felt an actual sympathy and even something close to friendship for the gill-breathing, bald, and dryly ironic creatures of the black space vessel.
Because of that mental kinship he set up—though hopelessly—a sort of table of the aspects of the problem before them. He did not believe that the aliens had any instinctive desire to destroy man. In fact, the study of communications from the aliens had produced on the Llanvabon a feeling of tolerance not unlike that between enemy soldiers during a truce on Earth. The men felt no enmity, and probably neither did the aliens. But they had to kill or be killed for strictly logical reasons.
Tommy’s table was specific. He made a list of objectives the men must try to achieve, in the order of their importance. The first was the carrying back of news of the existence of the alien culture. The second was the location of that alien culture in the galaxy. The third was the carrying back of as much information as possible about that culture. The third was being worked on but the second was probably impossible. The first—and all—would depend on the result of the fight which must take place.
The aliens’ objectives would be exactly similar, so that the men must prevent, first, news of the existence of Earth’s culture from being taken back by the aliens, second, alien discovery of the location of Earth, and third, the acquiring by the aliens of information which would help them or encourage them to attack humanity. And again the third was in train, and the second was probably taken care of, and the first must await the battle.
There was no possible way to avoid the grim necessity of the destruction of the black ship. The aliens would see no solution to their problems but the destruction of the Llanvabon. But Tommy Dort, regarding his tabulation ruefully, realized that even complete victory would not be a perfect solution. The ideal would be for the Llanvabon to take back the alien ship for study. Nothing less would be a complete attainment of the third objective. But Tommy realized that he hated the idea of so complete a victory, even if it could be accomplished. He would hate the idea of killing even nonhuman creatures who understood a human joke. And beyond that, he would hate the idea of Earth fitting out a fleet of fighting ships to destroy an alien culture because its existence was dangerous. The pure accident of this encounter, between peoples who could like each other, had created a situation which could only result in wholesale destruction.
Tommy Dort soured on his own brain which could find no answer which would work. But there had to be an answer! The gamble was too big! It was too absurd that two spaceships should fight—neither one primarily designed for fighting—so that the survivor could carry back news which would set one side to frenzied preparation for war against the unwarned other.
If both races could be warned, though, and each knew that the other did not want to fight, and if they could communicate with each other but not locate each other until some grounds for mutual trust could be reached—
It was impossible. It was chimerical. It was a daydream. It was nonsense. But it was such luring nonsense that Tommy Dort ruefully put it into the coder to his gill-breathing friend Buck, then some hundred thousand miles off in the misty brightness of the nebula.
“Sure,” said Buck, in the decoder’s word-cards flicking into place in the message frame. “That is a good dream. But I like you and still won’t believe you. If I said that first, you would like me but not believe me either. I tell you the truth more than you believe, and maybe you tell me the truth more than I believe. But there is no way to know. I am sorry.”
Tommy Dort stared gloomily at the message. He felt
a very horrible sense of responsibility. Everyone did, on the Llanvabon. If they failed in this encounter, the human race would run a very good chance of being exterminated in time to come. If they succeeded, the race of the aliens would be the one to face destruction, most likely. Millions or billions of lives hung upon the actions of a few men.
Then Tommy Dort saw the answer.
It would be amazingly simple, if it worked. At worst it might give a partial victory to humanity and the Llanvabon. He sat quite still, not daring to move lest he break the chain of thought that followed the first tenuous idea. He went over and over it, excitedly finding objections here and meeting them, and overcoming impossibilities there. It was the answer! He felt sure of it.
He felt almost dizzy with relief when he found his way to the captain’s room and asked leave to speak.
It is the function of a skipper, among others, to find things to worry about. But the Llanvabon’s skipper did not have to look. In the three weeks and four days since the first contact with the alien black ship, the skipper’s face had grown lined and old. He had not only the Llanvabon to worry about. He had all of humanity.
“Sir,” said Tommy Dort, his mouth rather dry because of his enormous earnestness, “may I offer a method of attack on the black ship? I’ll undertake it myself, sir, and if it doesn’t work our ship won’t be weakened.”
The skipper looked at him unseeingly.
“The tactics are all worked out, Mr. Dort,” he said heavily. “They’re being cut on tape now, for the ship’s handling. It’s a terrible gamble, but it has to be done.”
“I think,” said Tommy carefully, “I’ve worked out a way to take the gamble out. Suppose, sir, we send a message to the other ship, offering—”
His voice went on in the utterly quiet captain’s room, with the visiplates showing only a vast mistiness outside and the two fiercely burning stars in the nebula’s heart.
