Gonzalo laughed aloud when it came too him. He said, "Sure, if you know that MS is pronounced Miz, then you pronounce LS as Liz."

"To me," said Drake scornfully, "LS would have to stand for 'lanuscript' if it's going to rhyme with MS."

Avalon pursed his lips and shook his head. "Using TAIN'T is a flaw. You ought to lose a syllable some other way. And to be perfectly consistent, shouldn't the rhyme word IS be spelled simply S?"

Halsted nodded eagerly. "You're quite right, and I thought of doing that, but it wouldn't be transparent

enough and the reader wouldn't get it fast enough to laugh. Secondly, it would be the cleverest part of the limerick and would make the LS anticlimactic."

"Do you really have to waste all that fancy reasoning on a piece of crap like this?" asked Trumbull.

"I think I've made my point," said Halsted. "The humor can be visual."

Trumbull said, "Well, then, drop the subject. Since I'm host this session, that's an order… Henry, where's the damned dessert?"

"It's here, sir," said Henry softly. Unmoved by Trum-bull's tone, he deftly cleared the table and dealt out the blueberry shortcake.

The coffee had already been poured and Trumbull's guest said in a low voice, "May I have tea, please?"

The guest had a long upper lip and an equally long chin. The hair on his head was shaggy but there was none on his face and he had walked with a somewhat bearlike stoop. When he was first introduced, only Rubin had registered any recognition.

He had said, "Aren't you with NASA?"

Waldemar Long had answered with a startled "Yes" as though he had been disturbed out of a half-resentful resignation to anonymity. He had then frowned. He was frowning now again as Henry poured the tea and melted unobtrusively into the background.

Trumbull said, "I think the time has come for our guest to enter the discussion and perhaps add some portion of sense to what has been an unusually foolish evening."

"No, that's all right, Tom," said Long. "I don't mind frivolity." He had a deep and rather beautiful voice that had a definite note of sadness in it. He went on, "I have no aptitude for badinage myself, but I enjoy listening to it."

Halsted, still brooding over the matter of the limericks, said, with sudden forcefulness, "I suggest Manny not be the grill master on this occasion."

"No?" said Rubin, his sparse beard lifting belligerently.

"No. I put it to you, Tom. If Manny questions our

guest, he will surely bring up the space program since there's a NASA connection. Then we will go through the same darned argument we've had a hundred times. I'm sick of the whole subject of space and whether we ought to be on the moon."

"Not half as sick as I am," said Long, rather unexpectedly, "I'd just as soon not discuss any aspect of space exploration."

The heavy flatness of the remark seemed to dampen spirits all around. Even Halsted seemed momentarily at a loss for any other subject to introduce to someone connected with NASA.

Then Rubin stirred in his seat and said, "I take it, Dr. Long, that this is a recently developed attitude of yours."

Long's head turned suddenly toward Rubin. His eyes narrowed. "Why do you say that, Mr. Rubin?"

Rubin's small face came as close to a simper as it ever did. "Elementary, my dear Dr. Long. You were on the cruise that went down to see the Apollo shot last winter. I'd been invited as a literary representative of the intellectual community, but I couldn't go. However, I got the promotional literature and noticed you were along. You were going to lecture on some aspect of the space program, I forget which, and that was voluntary. So your disenchantment with the subject must have arisen in the six months since the cruise."

Long nodded his head very slightly a number of times and said, "I seem to be more heard of in that connection than in any other in my life. The damned cruise has made me famous, too."

"I'll go farther," said Rubin enthusiastically, "and suggest that something happened on the cruise that disenchanted you with space exploration, maybe to the point where you're thinking of leaving NASA and going into some other field of work altogether."

Long's stare was fixed now. He pointed a finger at Rubin, a long finger that showed no signs of tremor, and said, "Don't play games." Then, with a controlled anger, he rose from his chair and said, "I'm sorry, Tom. Thanks for the meal, but I'll go now."

Everyone rose at once, speaking simultaneously; all but Rubin, who remained sitting with a look of stunned astonishment on his face.

Trumbull's voice rose above the rest. "Now wait a while, Waldemar. God damn it, will all of you sit down? Waldemar, you too. What's the excitement about? Rubin, what is all this?"

Rubin looked down at his empty coffeecup and lifted it as though he wished there were coffee in it so that he could delay matters by taking a sip. "I was just demonstrating a chain of logic. After all, I write mysteries. I seem to have touched a nerve." Then, gratefully, he said, "Thanks, Henry," as the cup before him sparkled black to the brim.

"What chain of logic?" demanded Trumbull.

"Okay, here it is. Dr. Long said, 'The damned cruise has made me famous, too.' He said 'too' and emphasized the word. That means it did something else for him and since we were talking about his distaste for the whole subject of space exploration, I deduced that the something else it had done was to supply him with that distaste. From his bearing I guessed it was sharp enough to make him want to quit his job. That's all there is to it."

Long nodded his head again, in precisely the same slight and rapid way as before, and then settled back in his seat. "All right. I'm sorry, Mr. Rubin. I jumped too soon. The fact is I will be leaving NASA. To all intents and purposes, I have left it-and at the point of a shoe. That's all… We'll change the subject. Tom, you said coming here would get me out of my dumps, but it hasn't worked that way. Rather, my mood has infected you all and I've cast a damper on the party. Forgive me, all of you."

Avalon put a finger to his neat, graying mustache and stroked it gently. He said, "Actually, sir, you have supplied us with something we all like above all things-the opportunity to exert our curiosity. May we question you on this matter?"

'It's not something I'm free to talk about," said Long, guardedly.

Trumbull said, "You can if you want to, Waldemar. You needn't mention sensitive details, but as far as anything else is concerned, everything said in this room is confidential. And, as I always add when I find it necessary to make that statement, the confidentiality includes our esteemed friend Henry."

Henry, who was standing at the sideboard, smiled briefly.

Long hesitated. Then he said, "Actually, your curiosity is easily satisfied and I suspect that Mr. Rubin, at least, with his aptitude for guessing, has already deduced the details. I'm suspected of having been indiscreet, either deliberately or carelessly, and, either way, I may find myself unofficially, but very effectively, blocked off from any future position in my field of competence."

"You mean you'll be blackballed?" said Drake.

"That's a word," said Long, "that's never used. But that's what it will amount to."

"I take it," said Drake, "you weren't indiscreet."

"On the contrary, I was." Long shook his head. "I haven't denied that. The trouble is they think the story is worse than I admit."

There was another pause and then Avalon, speaking in his most impressively austere tone, said, "Well, sir, what story? Is there anything you can tell us about it or must you leave it at no more than what you have already said?"

Long passed a hand over his face, then pushed his chair away from the table so that he could lean his head back against the wall.
