He could hear noises from deep within this coming week." because, at one time or another, they had had to. Eckert had come into his office without saying a word and had watched And then Eckert had told him that Pendleton had taken the short way out. Eckert and he had talked it out and gone over the records. Pendleton hard-working. How long would it be before memories faded and all there was left matter of minutes before he would be asleep. Pendleton had been in his second year as attache on Tunpesh, a small There was no need to send more. Tunpesh had been inspected and maybe the Service had slipped up, as it sometimes did, and Tunpesh had the very few ships that ever came by Tunpesh. The captain had tried Tunpesh had been Pendleton's second assignment. Eckert and he had been chosen to go to Tunpesh and investigate. The two But that wasn't the real reason. Maybe Eckert thought so, but he knew better. The real reason they were going there was to find out why The thin red line was practically microscopic now and Templin could Their information on Tunpesh was limited. They knew that it had no anthropologist must have been routinely assigned to Tunpesh to furnish "How come our anthropologist on Tunpesh didn't come across with more information?" A drowsy mumble from the other cot: "He wasn't there long enough. He committed suicide not long after landing." slowly slipping. Takeoff was only seconds away. Warm breezes rustled through Eckert's graying hair and tugged gently as though it grew fast—it would certainly have plenty of time to grow before the next ship landed. He looked at the slim, dwindling shape that was the rocket, and was suddenly, acutely aware that he and Templin would be stranded for six months on a foreign and very possibly dangerous planet. And there would be no way of calling for help or of leaving before the six months were up. He stood there for a moment, drinking in the fresh air and feeling the warmth of the sun against his face. It might be a pleasant six months at that, away from the din and the hustle and confusion, spending the time in a place where the sun was warm and inviting. comfort. Like old dogs and octogenarians. Templin was looking at the scenery with a disappointed expression on Eckert nodded agreement. "It wouldn't fit, would it? It would be like a Eckert stared at them for a moment, wondering what it was that seemed and Templin. Templin studied them warily. "Better watch them, Ted. Even kids can be He couldn't be blamed for being jumpy, Eckert realized. This was his knees. When he got closer, Eckert became less sure of his age. He had seamed face and white hair aged him somewhat. Eckert still had the feeling that if you wanted to know his exact age, you'd have to look at his teeth or know something about his epiphyseal closures. "While you are here, you will need a place to stay. There is one ready, for or how long they were going to stay. But then again, perhaps the Eckert and Templin took a quick tour of the few rooms. They were well furnished, in a rustic sort of way, and what modern conveniences they didn't have they could easily do without. The youngsters who had carried their luggage left it outside and quietly faded away. It was Eckert opened one of the boxes they had brought along, Eckert shrugged. "That's one of the things you do out of habit, try "No, I'm afraid it's not." Eckert started unpacking some of the boxes. "Too healthy," Templin said. "There didn't seem to be any sick ones or they're playing a rehearsed part. Here we are, from an entirely He was keyed up, jumpy, Eckert realized. He would probably be seeing wood slat blinds, carrying the fragrance of the trees and the grass, and he inhaled deeply and let his thoughts wander for a moment. It was going to be pleasant to live on Tunpesh for six months—even if the six months were all they had to live. The climate was superb and the people seemed a cut above the usual primitive culture. If he ever retired some day, he thought suddenly, he would have to remember Tunpesh. It would He turned his head a little to watch Templin get ready for bed. There were advantages in taking him along that Templin probably didn't even realize. He wondered what Templin would do if he ever found out feelings and emotions would almost exactly be duplicated in Templin's. for an instant on a small metal box strapped to Templin's waist. A power pack, Eckert saw grimly, probably leading to the buttons on his There were disadvantages in taking Templin, too. Eckert put down the chain he had been whittling and reached for his Eckert hefted it in his palm. "The most important thing is that they least in fields where they have to have it." "How come they haven't gone any further?" "The important thing," Eckert mused, "is not if they have them, but if they'd use them. And I rather doubt that they would. We've been here for two weeks now and they've been very kind to us, seeing that we've had food and water and what fuel we need."

It meant that Eckert would among the Tunpeshans, and he'd have to watch Templin to see that he Templin nodded. "Sure." "The Tunpeshans know why we're here. We've dropped enough hints along nobody has volunteered any information about him. And he was an attache here for three Templin shrugged. "Murder. What other reason could there be?" Eckert rolled up the thin, slatted blinds and stared out at the "They grow their women nice, don't they?" "Physically perfect, like the men," Templin grumbled. "You could get an inferiority complex just from watching the people here. Everybody's so damn perfect. Nobody's sick, nobody's unhealthy, nobody is too fat or too thin, nobody's unhappy. The only variation is that they don't all look alike. Perfection. It gets boring after a while." down to it. I'm not ruling out the possibility of murder, either. I'm trying to keep an open mind." "What have we accomplished so far? What have we found out?" "We've got six months," Eckert said quietly. "Six months in which we'll try to live here inconspicuously and study the people and try to cultivate informants. We would get nowhere if we came barging in asking Tunpesh. If it is a case of murder, what happens when the natives find Templin's eyes dueled for a moment. Then he turned his back and walked " " enjoy himself, not to work or worry. He had heard about the and Templin had been invited. It was a good chance to observe native shrugged mentally. Templin looked as if he was about to break down and in Templin's getting excited and doing something he was bound to regret if Templin ever finds out Eckert."

What Nayova had said was something he'd make sure Templin never heard about. Eckert stared bleakly at his wine glass and tried to put the pieces of information together.
