BOB TURNED to practical considerations even before the Hunter started to bring them up. "I suppose," he said thoughtfully, "that you want to get back to the place where you found me and start scouting among the islands for your friend. How can you be sure he got ashore at all?"
"I can't, until I find traces of him," was the answer. "Did you say islands? I was hoping there would be only one within reasonable distance. How many are there in that region?"
"I don't know; it's quite a large group. The nearest to my own that I know of is about thirty-five miles to the northeast. It's a smaller one, but they have a power station there too."
The Hunter pondered. He had been almost exactly in the line of flight of the other ship up to the time he had gone out of control; as nearly as he could remember, they had both come nearly straight "down," so that even after his ship began spinning he should not have left that line by far. It had been his close-range screen that showed the other sinking after it had struck water; their points of landing could not be more than two or three miles apart. He explained this to Bob.
"Then if he got ashore at all, it's most likely on my island. That gives us about a hundred and sixty people to check, if he's still there. Are you sure he'll use a human body, or do we have to check everything alive?"
"Any creature large enough to spare the food and oxygen we use will serve. For a warm-blooded air-breather like yourself I should guess that the animal that was with you the day we met was about the smallest likely. However, I should expect him to use a human being, eventually if not at first. You represent, as far as I know, the only intelligent race on this world; and it has long been recognized by my people that an intelligent creature is the most satisfactory host. Even though this creature will not be seeking companionship, the fact that a man is probably the safest host available will guide him, I am sure."
"That is, if he is ashore yet. All right, we'll devote most of our attention to people. It's just as well, I guess; we have a needle in a haystack as it is." The Hunter was familiar with Bob's expression from his reading.
"That describes it well, except that the needle is camouflaged as a wisp of hay," was his answering comment.
They were interrupted at this point by Bob's roommate, returning to prepare for dinner, and there was no further chance for conversation that day. Bob saw the doctor about his arm during the afternoon, and, since the Hunter possessed no miraculous healing powers, the doctor considered its progress normal. It was pleasantly free from all signs of infection, "in spite,".the doctor remarked, "of that silly trick of yours. What did you try to close it with, anyway?"
"I did nothing to it," replied the boy. "It happened when I was on my way to the dispensary, anyway, and I thought it was just a scratch until the nurse started cleaning it and everything let go." He saw the doctor did not believe him, and decided there was little use pursuing the argument. Nothing had actually been said between him and his guest about keeping the latter's presence a secret, but it had occurred to the boy that if knowledge of the alien spread too far-assuming his story were believed, of course-it might have a serious effect on their chances of success, so he let the doctor finish his lecture on first aid and left as soon as he could.
Shortly after the evening meal he found an opportunity to get off by himself, and at once put a question to the Hunter.
"What do you plan to do about getting back to the island? Normally, I won't be going until the middle of June, nearly six months from now. Your fugitive has already had about that much time to get under cover, or out of the way. Do you plan to wait and let him bury himself deeper, or have you thought of some means of getting us there sooner?" The Hunter had been expecting the question and had an answer ready-one designed to teach him more about the boy's personality than he had been able to guess.
"My motions, from now on, are wholly dependent on yours. To leave you would be to waste much of the work of the last five months; true, I know your language, which would help me anywhere, but I suspect that securing the co-operation of anyone else would be a lengthy job. You are the only human being on whom I can count for understanding help. At the same time, it is true that the sooner I get back to the island the better it will be, so it seems best that you should come as well I know that you are not completely free to control your own actions, but if you could devise some means of getting us back there, it would be a great help. I can be of little assistance in the matter; you have grown up in this environment and can judge more accurately the chances of any given plan. All I am qualified to do is advise about the actions and nature of our quarry and what to do when we really start looking for him. What valid reason could you offer your people for returning immediately to the island?"
Bob did not answer at once. The idea of taking such a matter into his own hands was rather new to him; but inevitably it grew more attractive as he thought about it. Of course he would miss a lot of school, but that could be made up later. If the Hunter were telling the truth, this matter was much more important; and Robert could see no reason why his guest should deceive him. The alien, then, was right: he must solve the problem of getting home at once.
Simply disappearing was not to be thought of. Apart from the purely practical difficulties of crossing the continent and a good part of the Pacific without assistance, he had no desire to cause his parents anxiety if it could be avoided. That meant that a good excuse for the journey must be found, so that it could be undertaken with official approval.
The more he thought about it the clearer it seemed that only illness or physical injury would serve. Homesickness had been known to produce results in one or two cases, but Robert remembered what he had thought of the individuals involved and decided he didn't want that reputation. It would be nice to acquire an injury in some manner which would reflect credit on himself-through a heroic rescue or some similar adventure-but he had sense enough to realize that the opportunity was small and the actual merit of the idea nil. Of course the hockey season was still on; anything might happen of its own accord. As for illness, that could not very well be acquired at will. He could perhaps imitate something well enough to fool friends and teachers, but he did not for an instant deceive himself into thinking he could fool a doctor for any length of time. Faking seemed out, therefore. The usual run of ideas, such as false telegrams requesting his presence, pretense of bad news from home, and all their variations ran through his mind, for he had read his share of the more melodramatic literature; but none of them satisfied the objections which his sound common sense at once raised. He found himself in a complete quandary, and told the Hunter so after many minutes of thought. "This is the first time I have regretted choosing such a young host," answered the alien. "You lack the freedom of travel that an adult would take for granted. However, I am sure you have not exhausted your fund of ideas. Continue to think, and let me know if I can help in any of your plans." That terminated the conversation for the time. Bob left the room moodily.
He brightened up presently, however, shelved his worries for the moment, and presently was engaged in a game of ping-pong with one of his classmates in the recreation room next to the gym. The relaxation allowed his subconscious mind to work on the problem, and in the middle of the first game he had another idea-as luck would have it, at a time when he could neither tell the Hunter nor secure his views on the matter. He became so preoccupied with the plan that the game, which had been going well for him up to this point, deteriorated almost to a slaughter. He managed to pull himself together for the next game only by reminding himself that it was certain to be some time before he could get in touch with his guest, even if he stopped playing. Also, this early he was developing an exaggerated fear of doing anything abnormal least his secret should be suspected; and there was nothing normal about his being beaten so thoroughly as he had just been.
It was indeed quite a time before he managed another talk with the Hunter. When he returned to his room, the other occupant was already there, and his presence prevented conversation not only until "lights out" but throughout the night, as Bob was not sure how much disturbance it would take to wake the fellow. Anyway, he could not very well see the Hunter's answers in the dark. The next day was Monday, with classes, and he was not alone until after supper, when, in near desperation, he took some books and went in search of an empty classroom. There, talking in a low tone to escape notice from anyone passing the door, he finally managed to unbottle the repressed questions. He started, however, with a point other than his idea.
"Something will have to be done about this," he said. "You can talk to me whenever I'm not actually doing something else, but I can't say anything to you when anyone's around without having them think I'm crazy. I've had an idea since last night and have been wondering when I could tell you."
"The conversation problem should not be difficult," answered the Hunter. "If you simply talk in an inaudible whisper-even keep your lips closed if you wish-I think I can learn quite easily to interpret the motions of your vocal cords and tongue. I should have thought of it long ago but gave no particular attention to the need for secrecy with which we are faced. I shall start practice at once. It should not be hard; I understand many of your people become quite adept at lip reading, and I have more than lips to go by. What was the idea that was worrying you so?"
"I can see no way of getting to the island, except through feigning sickness and being ordered to take an early vacation. I can't possibly fake an illness well enough to fool a doctor, but you are in a position to give me all sorts of symptoms-enough to drive them crazy. How about it?"
The Hunter was hesitant in his answer.
"It is certainly a possibility, but there are objections. You, of course, cannot realize how deeply bred into us is the repugnance to the idea of doing anything that can harm our hosts. In an emergency, with a being whose physical make-up I knew completely, I might carry out your plan as a last resort; in your case I could not be sure that no permanent harm was going to result from my actions. Do you see?"
"You have lived in my body for more than five months, you say. I should think you must know me as well as you ever will," Bob objected.
"I know your structure but not your tolerances. You represent a completely new species to me, of which I have data on only one individual. I do not know how long given cells can do without food or oxygen; what constitutes the limiting concentration of fatigue acids in your blood; what interference your nervous and circulatory systems can stand. Those things obviously I could not test without harming and possibly killing you. There are, I suppose, a few things I might do in the line you suggest, but I certainly would not like it; and, in any case, how do you know that you would be sent home in case of illness? Would they not be more likely to hospitalize you here?"
The question silenced Bob for several seconds; that possibility had not occurred to him.
"I don't know," he said at last. "We'll have to find something that calls for a rest cure, I guess." His features wrinkled in repugnance at the idea. "I still think you could do something about it without having a nervous breakdown."
The Hunter was willing to concede that point but was still reluctant to interfere with his host's vital processes. He said he would "think it over," and advised the boy to do the same-also to produce another idea, if possible.
This Robert agreed to do, though he felt the chances of success were small. The Hunter was not sanguine, either. Little as he knew of human psychology, he was pretty sure that Bob could not really work on another plan until his present one was proved impossible rather than merely undesirable. The boy still liked the plan and had no real conception of the way it affected the Hunter's feelings.
Consequently, the only real progress made in the next few days was in communication. As the detective had expected and hoped, he was able quickly to interpret the motions of the boy's vocal cords and tongue, even when he kept his lips nearly closed and spoke in a whisper audible to no one but himself. Answering was easy, provided Bob's current occupation left him free to turn his eyes on some relatively blank space. Also, a few mutually understood abbreviations began to creep in, so that their exchange of ideas speeded up noticeably. Neither, however, produced another idea for getting the boy away from school.
An observer during those few days, familiar with the course of events not only between Bob and his guest but in the offices of the school officials, would have been amused. On the one hand, the Hunter and his host were concentrating on trying to find an excuse for leaving; on the other, the headmaster and his staff were wondering volubly about the cause of the boy's suddenly developed inattention, listlessness, and general failure to measure up to his earlier standards; more than one of them remarked that it might be well to get the youngster back to his parents' hands for a time. The Hunter's mere presence- or rather, Bob's knowledge of it-was producing conditions bound in the end to lead to the very situation they wanted. He was, of course, doing the boy no physical damage, but the preoccupation with the current problem and a number of too-public conversations with the concealed alien constituted a behavior pattern only too noticeable to those responsible for Bob's well-being.
The doctor was eventually consulted on the matter. He reported the boy's health sheet clean, with no illness whatever this term and only two minor injuries. He examined the still-healing arm again, on the chance that an unsuspected infection might be responsible, but of course found nothing. His report left the masters mystified. Bob had changed from a normally pleasant and gregarious youngster to a solitary and at times almost sullen individual. At their request the doctor had a private interview with Robert.
He learned nothing concrete this time, either, but he gained the impression that Bob had a problem on his mind which he did not wish to share with anyone. Being a doctor, he formed a perfectly justified but quite erroneous theory on the nature of the problem, and recommended that the boy be returned to the care of his parents for a few months. It was as simple as that!
The headmaster wrote a letter to Mr. Kinnaird, explaining the situation as the doctor saw it, and stating that, if there were no objections, he planned to send Robert home immediately until the opening of the fall term.
Bob's father rather doubted the doctor's theories. He knew his son well, considering the relatively small amount he had seen of him in recent years; but he concurred with Mr. Raylance's suggestion. After all, if the kid were not doing well at school it was a waste of time to have him there whatever the reason for the trouble. There was a perfectly good doctor and-though Mrs. Kinnaird had her doubts-a perfectly good school on the island, and it would be easy to fill the gap in his education while a more careful study of the situation was being made. Also, quite apart from these reasons, Mr. Kinnaird would be glad of the chance to see more of his son. He cabled the school authorizing Bob's return, and prepared for his arrival.
To say that Robert and the Hunter were surprised at the news is a distinct understatement. The boy stared wordlessly at Mr. Raylance, who had called him into his office to inform him of the imminent journey, while the Hunter strove unsuccessfully to read a few papers which were exposed on the headmaster's desk.
Eventually Bob recovered the use of his voice. "But what is the reason, sir? Has anything happened at home?"
"No, everything is all right. We felt that you might be better off there for a few months, that's all. You haven't been hitting your usual mark lately, have you?"
To the Hunter, this remark explained the situation with crystal clarity, and he metaphorically kicked himself for not having foreseen it; to Bob, understanding came more slowly.
"You mean-I'm being kicked out of school? I didn't think it was that dad-and it's only been a few days."
"No, no, nothing of the sort." The headmaster missed the implications of Bob's last remark. "We notice that you seemed to be having trouble, and the doctor thought you needed a little time off. We'll be glad to have you back next fall. If your like, we can send along a study outline with you, and the teacher on the island can help you keep up with it, You can spread that work through the whole summer and will probably be able to stay with your class when you come back. Is that all right? Or"-he smiled- "is it just that you don't want to go home?"
Bob returned the smile rather lamely. "Oh, I'll be glad enough to go, all right. I mean-" He paused, rather embarrassed as he realized another possible construction of his words.
Mr. Raylance laughed aloud. "All right, Bob. Don't worry-I understand what you mean. You'd better get packed and say good-by to your friends; I'll try to get you a reservation for tomorrow on the usual ah" route. I'm sorry you're going; the hockey team will certainly miss you. However, the season is nearly over, and you'll be back in time for football. Good luck."
They shook hands, and Bob dazedly went to his room and began to pack. He said nothing to the Hunter; it was not necessary. He had long since given up taking the statements of his elders at face value simply because they were his elders, but try as he might he could find no ulterior motive lurking behind the words and actions of the headmaster. He decided, for the time being, to take his luck without question and leave the next step to the Hunter.
That individual had ceased to worry from the time he had realized the import of Mr. Raylance's words. The removal of a source of anxiety affected him just as it frequently does a human being-he tended to feel, for a time, as though troubles were a thing of the past. It might be too much to say that he felt his job was as good as done; but there would have been some excuse if he had felt that way. He was a good detective. He had, of course, some failures against his record, but not one of them had occurred while be had the advantage of an intelligent and co-operative host to supply the physical powers his own body lacked. Bob was not Jenver, but he had come to feel strongly attached to the youngster.
This atmosphere of self-congratulation continued during Bob's packing and even through part of the trip. Mr. Raylance was successful in obtaining the reservation, and the next day Bob took the bus to Boston and caught the noon plane to Seattle, where they were to change to the TPA plane. During the ride and flight the boy talked with his guest whenever possible, but the conversation was purely about the events and scenes of the trip. They did not turn to business until they were over the Pacific, for Bob always accepted without any particular thought the Hunter's ability to take care of things once they reached the scene of action.
"Say, Hunter, just how are you going to find this friend of yours? And what will you do to him then? Have you some means of getting at him without hurting his host?"
It was a shock. For once the Hunter was glad that his method of speech was less easily used than Bob's. Had it been otherwise, he would almost certainly have started talking before he realized he had nothing to say. In the next five seconds he wondered whether he might not have left behind somewhere the mass of tissue that normally served him for a brain.
Of course his quarry had long since hidden-must by now be established in another body, just as the Hunter himself was. That was nothing unusual. Normally, however, such a being-undetectable by sight, sound, smell, or touch-was detected by chemical, physical, and biological tests, with or without the co-operation of the being acting as host. He knew all those tests; be could administer them, in some cases, so rapidly that while merely brushing against a suspected organism he could tell if one of his own people were present, and even make a good guess at his identity. There were something like a hundred and sixty people on the island, Bob had said. They could be covered in a few days' testing-but he could not make the tests!
All of his equipment and supplies had gone with his ship. Even with the fantastic assumption that he could find the hulk again it would be folly to suppose that instruments had remained unbroken and chemical containers sealed through the crash and the five subsequent months under salt water.
He was on his own, as few policemen had ever been before; hopelessly isolated from the laboratories of his own world, and the multitudinous varieties of assistance his own people could have given him. They did not even know where he was, and with a hundred billion suns in the Milky Way system…
He remembered, wryly, that Bob had actually brought up the question days before and the cavalier manner in which he had disposed of it Now it was bitterly clear that the summary they had made of the situation on that occasion had been glaringly accurate. They were looking for a needle in a haystack-a haystack whose human straw numbered more than two billion; and that deadly, poisoned needle had thoughtfully crawled inside one of them! Bob got no answer to his question.
