Three years on the Moon and they didn't want him to come back. Three years on the Moon and they thought he'd be glad to stay for more. Just raise his salary or give him a bonus, the every-man-has-his-price didn't work right. And for double his salary they thought he'd be glad to stay for another year and a half. Or maybe three. He should probably be glad he had the opportunity. The key started to stutter again, demanding an answer. He tapped out his reply: " No! " fit of bureaucratic rage. Chapman stuffed a rag under it and ignored it. He turned to the hammocks, strung against the bulkhead on the other side of the room. The chattering of the key hadn't awakened anybody they were still asleep, making the animal noises that people usually make in slumber. "They wanted me to stay until the next relief ship lands," Chapman whispered back. "What did you say?" He shrugged. "No." "You kept it short," somebody else whispered. It was Donley, up and man to stay on the job a while longer." " All they're trying to do," Chapman said sarcastically. "They've got No, Chapman thought, some of us aren't going back. You aren't. And for breakfast duty. The others started lacing up their bunks, getting ready for their last day of work on the Moon. In a few hours they'd be relieved by members of the Third research group and they'd be on their way back to Earth. And that includes me, Chapman thought. I'm going home. I'm finally That's what happened to guys like Dixon, Chapman thought. On the Moon, Klein came back with the coffee.

Dowden and Bening looked blank for a minute and of that. I suppose none of us have. We've been like little kids who have waited so long for Christmas that they just can't believe it when it's finally Christmas Eve." Klein nodded in agreement. "I haven't been here three years like you Chapman grinned. "Oh, just somebody. What are you going to do, Dick?" Everybody laughed and Chapman turned to Klein. to the expedition. Then I think I'll go home and see my wife." They were quiet. "I thought all members of the groups were supposed to be single," Donley said. "They are. And I can see their reasons for it. But who could pass up They ran through it twice. They were beginning to feel it now, Chapman The others chimed in and Chapman grinned. Yesterday or a week ago they couldn't have done it. He had been there too long and he had hated it too much. The party quieted down after a while and Dowden and Bening finished Chapman stopped them at the lock. "Remember to check your suits for leaks," he warned. "And check the valves of your oxygen tanks." Donley looked sour. "I've gone out at least five hundred times," he said, "and you check me each time." "And I'd check you five hundred more," Chapman said. "It takes only through one of those and that's it, brother." Donley sighed. "Chap, you watch us like an old mother hen. You see we Only Klein and Chapman were left in the bunker. Klein was at the work just get to thinking and wanting—and there's nothing you can do about it. You talk about it and it just makes it worse." "Yes." "You're not like Dahl. You've never mentioned it." "Same reason you didn't mention your wife. You get to thinking about it." Klein flipped the lid on the specimen box. "Going to get married when "Settle down in a small cottage and raise lots of little Chapmans, eh?" Chapman nodded. He put away the box and came over to the port. Chapman moved over so The day before the Second group came, he went out to finish some work he was interested in. He forgot to check for leaks and whether or not time." "He had his walkie-talkie with him?" "Yes. It worked fine, too. We heard everything that went through his mind at the end." machinery. When it occurred to us that somebody was going to have to stay over, I volunteered. I thought the others were so important that it was better they should take their samples and data back to Earth Chapman frowned. "Frankly, I hadn't thought of that. I don't believe it's somebody else's turn now. He volunteered for it. I think I was fair in explaining all about the job when you talked it over among yourselves." wouldn't make any difference to me. I'm sorry if Dahl is young. So was I. I've lost three years up here. And I don't intend to lose any more." week before, when he had opened his small gear locker and transferred its meager belongings to the bag. He hadn't actually needed to pack, of course. In less than twenty-four probably use them or maybe one of the boys in the Third. But it wasn't like going home unless you packed. It was part of the ritual, like marking off the last three weeks in pencil on the gray mean, considering the advance of—" "No," Chapman interrupted bluntly. "I don't. Not at least for ten years. The fuel's too expensive and the trip's too hazardous. On freight charges alone you're worth your weight in platinum when they send you here. Even if it becomes cheaper, Bob, it won't come about help himself. "Well, yes, more or less. Oh, God, Chap, I know you want to go home! But I couldn't ask any of the others you were the only one who could, the only one who was qualified!" Chapman felt tired. The good feeling he had about going home was slowly evaporating. "If you have any report to make, I think you had better get at it," he cut in, keeping all the harshness he felt out of his voice. "It'll be too late after the relief ship leaves. It'll be easier to give the captain your report than try to radio it back to Earth from here." company!" He dashed for his suit. Dowden and Bening piled after him and all three started for the lock. Chapman was standing in front of it. "Check your suits," he said softly. "Just be sure to check." group had been when they had landed. Like Chapman had been in the First. Donley and the others were all over them. How was it back on Earth? Who had won the series? Was so-and-so still teaching at the university? What was the international situation? Chapman had gone through it all before. But was Ginny still Ginny? Some of the men in the Third had their luggage with them. One of them—a husky, red-faced kid named Williams—was opening a box about a foot square and six inches deep. Chapman watched him curiously. Chapman cut off a single blade with his fingernail and put it between Chapman sympathized.

They hadn't had a captain on the First "Well, look, Mr. Chapman, is there any place where we can talk together Chapman jerked a thumb toward Dahl. "Ask him. He's in charge now." "Oh, yes, big plans Chapman nodded. "They could use a little privacy up here." I wanted to talk to you, Chapman. The Commission talked it over and "The answer is no," Chapman said.
