Rubin said, "Are you sure those six are indeed the only possibilities. Are you sure you really didn't mention it to anyone else?"

"Quite sure," said Long dryly.

"You might not remember having done so," said Rubin. "It could have been something very casual. Can you be sure you didn't?"

"I can be sure I didn't. The radiophone call came not long before dinner. There just wasn't time to tell anyone before dinner. And once I got away from the table, I was back in the cabin before I as much as said anything to anybody. Anything at all."

"Who heard you on the phone? Maybe there were eavesdroppers."

"There were ship's officers standing around, certainly. However, my boss expressed himself Aesopically. I knew what he meant, but no one else would have."

"Did you express yourself Aesopically?" asked Halsted. "I'll tell you exactly what I said. 'Hello, Dave.' Then I said, 'God damn it to hell.' Then I hung up. I said those seven words. No more."

Gonzalo brought his hands together in a sudden, enthusiastic clap. "Listen, I've been thinking. Why does the job have to be so planned? It could be spontaneous. After all, everybody knows there's this cruise and people connected with NASA are going to talk and there might be something interesting on. Someone-it could have been anyone-kept searching various rooms during the dinner hour each day and finally came across your paper-"

"No," said Long sharply. "It passes the bounds of plausibility to suppose that someone would, just by chance, find my paper just in the hour or two after I had announced that a classified lecture was sitting on my desk. Besides, there was nothing in the paper that would have given any indication of importance to the nonexpert. It was only my own remark that would have told anyone it was there and that it was important."

Avalon said thoughtfully, "Suppose one of the people at the table passed on the information, in perfect innocence. In the interval they were away from the table, they might have said to someone, 'Did you hear about poor Dr. Long? His paper was shot out from under him?' Then that someone, anyone, could have done the job."

Long shook his head. "I wish that could be so, but it can't. That would only happen if the particular individual at my table were innocent. If the Smiths were innocent when they left the table, the only thing on their minds would be the hot chocolate. They wouldn't stop to chat. The Doctor would be thinking only of getting the ointment. By the time Jones left the table, assuming he was innocent, he would have forgotten about the matter. If anything, he would talk about the hot chocolate, too."

Rubin said suddenly, voice rising, "All right. What about Miss Robinson? She left before the hot-chocolate incident. The only interesting thing in her mind would have been your dilemma. She might have said something."

"Might she?" said Long. "If she is innocent, then she was really doing what she said she was doing, going to the bathroom in her cabin. If she had to desert the dinner table to do so, there would have had to be urgency; and no one under those conditions stops for idle gossip."

There was silence all around the table.

Long said, "I'm sure investigation will continue and eventually the truth will come out and it will be clear that I'm guilty of no more than an unlucky indiscretion. By then, though, my career will be down the drain."

"Dr. Long?" said a soft voice. "May I ask a question?"

Long looked up, surprised. "A question?"

"I'm Henry, sir. The gentlemen of the Black Widowers organization occasionally allow me to participate-"

"Hell, yes, Henry," said Trumbull. "Do you see something the rest of us don't?"

"I'm not certain," said Henry. "I see quite plainly that Dr. Long believes only the six others at the table might possibly be involved, and those investigating the matter apparently agree with him-"

"There's no way not to," said Long.

"Well, then," said Henry. "I am wondering if Dr. Long mentioned his views on curry to the investigators."

Long said, "You mean that I didn't like curry?"

"Yes," said Henry. "Did that come up?"

Long spread his hands and then shook his head. "No, I don't think it did. Why should it? It's irrelevant. It's just an additional excuse for my talking like a jackass. I tell it to you here in order to collect sympathy, I suppose, but it would carry no weight with the investigators."

Henry remained silent for a moment, and Trumbull said, "Does the curry have meaning to you, Henry?"

"I think perhaps it does," said Henry. "I think we are in rather the position Mr. Halsted described earlier in the evening in connection with limericks. Some Limericks to be effective must be seen; sound is not enough. And some scenes to be effective must be seen."

"I don't get that," said Long.

"Well, Dr. Long," said Henry. "You sat there in the ship's restaurant at a table with six other people and therefore only those six other people heard you. But if we could see the scene instead of having you describe it to us, would we see something clearly that you have omitted?"

"No, you wouldn't," said Long doggedly.

"Are you sure?" asked Henry. "You sit here with six other people at a table, too, just as you did on the ship. How many people hear your story?"

"Six-" began Long.

And then Gonzalo broke in, "Seven, counting you, Henry."

"And was there no one serving you at table, Dr. Long? You said the Doctor had asked you about the speech just as curried lamb was put before you and it was the smell of curry that annoyed you to the point where you burst out with your indiscretion. Surely, the curried lamb didn't place itself before you of its own accord. The fact is that at the moment you made your statement, there were six people at the table before you, and a seventh standing just behind you and out of sight."

"The waiter," said Long in a whisper.

Henry said, "There's a tendency never to notice a waiter unless he annoys you. An efficient waiter is invisible, and you mentioned the excellence of the service. Might it not have been the waiter who carefully engineered the spilling of the hot chocolate to create a diversion; or perhaps he who took advantage of the diversion, if it was an accident? With waiters many and diners few, it might not be too noticeable if he vanished for a while.

Or he could claim to have gone to the men's room if it were indeed noticed. He would know the location of the cabin as well as the Doctor did, and be as likely to have some sort of picklock."

Long said, "But he was an Indonesian. He couldn't speak English."

"Are you sure? He'd had a three-month cram course, you said. And he might have known English better than he pretended. You would be willing to conceive that Mrs. Smith was not as sweet and thoughtful underneath as on the surface, and that Mrs. Jones's vivacity was pretense, and the Doctor's respectability and Smith's liveliness and Jones's devotion and Miss Robinson's need to go to the bathroom. Might not the waiter's ignorance of English also be pretense?"

"By God," said Long, looking at his watch. "If it weren't so late, I'd call Washington now."

Trumbull said, "If you know some home phone numbers, do call now. It's your career. Tell them the waiter ought to be investigated, and for heaven's sake, don't tell them you got the notion from someone else."

"You mean, tell them I just thought of it? They'll ask why I didn't think of that before."

"Ask them why they didn't. Why didn't they think a waiter goes with a table?"

Henry said softly, "No reason for anyone to think of it. Only very few are as interested in waiters as I am."
