Most important, he knew that man was the only intelligent species on Earth, and that man had science, apparently a fairly advanced science. While Tommy’s knowledge of science was almost nil (he knew a little about elementary electricity, enough to wire a doorbell), he knew that science and scientists existed, and that (this was of major importance) science included electronics. The meaning of the word electronics was vague to him, but he had seen (and owned) a radio set. He had seen television. And he knew what radar did, if not how it worked. Where these things existed there was knowledge of electronics.
And the mind thing’s eventual goal was to obtain control of an electronicist, one who not only knew the subject but who had or could obtain access to equipment and components. It would probably take him several steps—several intervening hosts—to get there, but he knew now that it could be done if he planned properly. And he had to do it. He wanted to go home.
He came from a planet of a sun seventy-three light-years away, in the direction of the constellation Andromeda, a sun too faint from Earth ever to have been named, although it has a number in Earth’s star catalogues.
He had not come voluntarily; he had been sent. Not as a scout or as the spearhead of an invasion (although it could turn out that way if he could get back), but as an exile. He was a criminal. To explain what his crime had been would require the explanation of a social system so utterly alien to ours as to be almost incomprehensible; suffice it to say that he had committed a crime and that his punishment was exile.
He had not come in a spaceship. He had been sent along a—call it a force beam; that’s a poor description of it but is as nearly accurate as any other simple phrase, in our language, would be. Transmission had been instantaneous; one second he was in the projector back home, the next second he was lying beside a path in the woods north of Bartlesville, Wisconsin, having experienced no impact on arrival.
The planet of his exile had been chosen at random, and with no knowledge of whether it was inhabited or inhabitable, out of the billions of planets in the galaxy which his race had charted but had never got around to investigating; there were so many billion planets that they never would get around to investigating more than a small fraction of them. The reason why they were able to chart planets as readily as we chart stars was that their equivalent of a telescope, based on magnification of the sense of perception instead of the far inferior sense of sight, enabled them to “see” planets almost as far as we are able to see stars.
So now he was here, and now he wanted to go home. It was far from impossible, for two reasons.
First, he had been extremely lucky in having come to a planet that had not only reasonably intelligent beings, but a science and a technology, however inferior to his own. The chances had been, say, a hundred thousand to one against it. If he had been sent to an uninhabited planet, he would have been completely helpless. If to a planet that had life but had not yet developed intelligence (like Earth of a million years ago) he might have been able to construct a projector to send himself back but the odds, were against it. (Can you imagine the difficulties of a dinosaur, even with intelligent direction, in finding and refining germanium and then using it to make a transistor?)
Second, he would be welcomed home and pardoned—even honored—if he could get there. The exiles always had that chance, and one out of hundreds of them made it.
A returned exile was honored very highly indeed, and became a hero, if he brought back with him news of a species better fitted for hosts than the ones in current use. And that the mind thing could do. In having Tommy carry him he had discovered the opposable thumb and it was, as far as he knew, unique in the galaxy. It made grasping and handling things so much easier. Quite possibly he could make his projector big enough to let him take a sample human host back with him. If he did that he would save them sending a scouting expedition; they could make their first slave raid in full force.
All that was within his grasp if he worked slowly and carefully and made no mistakes. He had made one already, he now realized. He had lessened his present host’s value to him by making him act in a manner against human mores, thereby attracting attention to him. For a while at least Tommy Hoffman would be an object of curiosity and suspicion, which would somewhat limit his usefulness. People would be watching him to see if he did anything else that seemed strange to them.
What he should have done, and would have done if he had taken a few minutes to study Tommy’s thoughts, was this: He should have had Tommy come to him and move him from his dangerously exposed position, but not all the way to the cave. Tommy could have moved him to a place of temporary concealment—the high grass only a few feet off the path would have been good enough and then returned and lain down beside the sleeping girl and pretended to sleep himself. That would have given him time to learn enough about Tommy and the girl, about human actions and emotions, so that when they awakened, he could have appeared to her to be perfectly normal. Possibly he could even (again to use the euphemistic phrase from Tommy’s mind) have “gone another round” with her. The mind thing wouldn’t have enjoyed it, of course; when in a host he felt no pain when he had it killed, but neither did he share any of its pleasurable sensations. He would have had intercourse with the girl simply because it would have been the natural thing for Tommy to have done.
Then they would have dressed and returned home as they had intended to do. (Once inside a host, he could control it at any reasonable distance.) In the morning Tommy could have come back, alone, and moved him to this much better place of concealment in the cave, and then returned home without having aroused anyone’s curiosity.
That’s what he should have done, but it was too late by the time he realized it. His alternate plan would have to suffice. It was based on the concept of something called amnesia that he had found in Tommy’s mind.
Tommy could stay here on guard in front of the cave entrance all night. Early in the morning he could go back and get his clothes (the girl would have left when she got worried enough, but she wouldn’t have taken them) and walk home. His story would be simple. He and the girl had got tired and lain down to rest. He’d gone to sleep. And at dawn he’d waked up in a different place, over a mile away and with no recollection of how he got there. He could hardly have walked that far in his sleep—and besides Tommy had never sleep-walked—so he must have had some reason for going there, but he couldn’t remember what it was. It must be amnesia. They’d have him talk to a doctor a time or two, but nothing would come of that. And henceforth Tommy would, at least in the sight of others, appear to act completely normal—until his usefulness as a host came to an end; then he would either kill himself or, if possible, arrange his own death in some manner that would make it seem accidental.
Besides its simplicity and incontrovertibility, Tommy’s story had another advantage; it would not cross up the girl’s story, whichever way she told it. She might have been frightened enough to tell her family the whole truth—that she and Tommy had slept naked and that he had gone off in that state, or she might well have left that part out. If his first story didn’t mention clothes at all, and if she hadn’t, then their stories would match. If taxed with the fact that she had told the story differently, he could sheepishly admit that, yes, he had been naked when he had gone to sleep and had awakened the same way in the morning. His original omission of that part of the story would be entirely understandable to everyone.
