"Trouble?" asked Jeff, a little shakily. "Why am I in trouble?" He was only fourteen, for all his height, and it seemed to him that he had been asking that question for at least twelve of those years.

At first he had had to ask it of his parents, then his older brother, his teacher, and his computer control. It hadn't been too bad then, but having to ask it now of the head of the Space Command was setting a new record. He didn't exactly feel good about it.

Standing right next to Jeff was Agent Two Gidlow, who was no help at all. He was dressed entirely in gray, and his angry red eyes glared at Jeff with contempt. Even his skin seemed sallow and off-color.

"You're not only in trouble," Gidlow said to Jeff. "You are trouble. " He turned to Admiral Yobo and cut the air horizontally with a sweep of his hand, as if that were Jeff's neck it was passing through. "Admiral, when a troublemaker muddles the computers…"

The admiral stayed calm. The Space Academy, which was under Space Command, had serious problems to face and he was at the cutting edge of it all. The matter of a misbehaving cadet was not something he had to twist his insides over.

Besides, he liked Jeff, who was the kind of tall and clumsy teenager he himself had once been some years ago (though that was beside the point), and he found himself wearied now and then by Gidlow's strenuous disciplinarianism (though that was beside the point, too).

"See here, Gidlow," said Admiral Yobo with a mild frown corrugating his wide, black forehead, "why all the fuss? Remember that you are not part of the academy and have no authority here. If you're going to follow up every prank by hauling the cadet in question into my office to be grilled by Federation Security Control, I'm going to have no time for anything else. All I've gotten so far is that he was trying to sleep-learn, and there's nothing in the rules against that."

"If you do it right, there isn't, Admiral," said Gidlow. "Doing it wrong is another thing. He tied into the main computer network-he says by accident-"

"Of course by accident, Agent Gidlow," said Jeff earnestly. He pushed his curly brown hair out of his eyes and stood as straight as he could so he'd be taller than the agent. "I mean why should I do it on purpose?"

Gidlow smiled unpleasantly. His rather pointed teeth seemed as gray as his clothing and his sallow skin. "If you prefer, Cadet, you did it out of stupidity, which is no better. Admiral, I bring this to you because it is a security expulsion matter, and that's for you to handle."

"Security?"

"The way this cadet tied himself into the main computer network-by accident, he says-has resulted in the kitchen computer getting the wrong set of data."

"Data? What data?" Gidlow pursed his lips, "It would not be proper to discuss it before a cadet."

"Don't be a fool, Gidlow. If this is an expulsion matter, the young man has a right to know what he's done."

"One thing is-and it may be enough all by itself-as a result of his idiotic link-up, everything is being filtered through the kitchen computer. And this means, among other things, that all the recipes are now in Martian Colony Swahili."

The admiral, who had been playing with the buttons on his desk, began to chuckle as he stared into his private viewer. "I see that one Jefferson Wells, age fourteen, failed to pass Martian Colony Swahili last semester."

"Yes, sir," said Jeff, trying not to fidget. "I didn't seem to get the hang of it. I'm doing makeup now, sir, and I was trying to sleep-learn before the final exam next week. I'm terribly sorry about the computer. I thought I was following the directions correctly, and I can't think where I went wrong."

"You can't think, period," said Gidlow. "What it amounts to, of course, Admiral, is that until the recipes are reconverted into Terran Basic, or until the kitchen computer is reprogrammed to handle Martian Swahili, there's no way of running the kitchen. No one in Space Command is going to be able to eat. We won't even be able to have canned food released. I think," he added glumly, "we might be able to get a supply of stalk celery that hasn't yet been indexed."

"What!" roared Yobo.

Jeff stirred uneasily. He remembered with a sinking sensation that Admiral Yobo was famous for his thorough knowledge of Martian Swahili, including its colorful expletives-and also for his prodigious appetite.

"Yes, sir," said Gidlow stiffly.

"But that's ridiculous," said Admiral Yobo through clenched teeth. "The computer should know Martian."

Gidlow looked sidewise at Jeff, who was trying to stiffen his stand at attention even further. He said, almost in a whisper, "Very important secrets have been shoved into the kitchen computer, along with everything else, and Computer Control now says that everything in the kitchen computer is classified. That means the cook-robots won't work, and it will be a long haul before we can get into the kitchen computer to do anything about it."

"Which means," said the admiral, "it will be a long haul before I-before any of us can get anything to eat."

"Yes, sir, which is why this is expulsion material. In fact, we're going to have to take this cadet mentally apart before we expel him, in order to find out if he's learned any classified material."

"But Mr. Gidlow," said Jeff a little hoarsely, for his mouth had gone dry with fright-he had heard stories about what could happen to people under mental invasion-"I don't know any Swahili, not even now. The sleep-learning didn't do any good, so I didn't get any classified material. I didn't get anything except some strange Martian recipes-"

"Strange?" said the admiral, glowering. "You think Martian food is strange?"

"No, sir, that's not what I meant-"

"Admiral," Gidlow said, "he clearly got classified information he thinks are recipes. He must be taken apart."

Jeff felt desperate. "There's nothing classified in me. Just recipes. What makes them strange is that they're in Martian Colony Swahili, which I keep telling you I don't understand."

"Then how do you know they're recipes? Eh? Eh? Admiral, this little troublemaker is convicting himself with his own mouth."

"I know the Martian names for some of their dishes," said Jeff. "That's how I know. I like to go to Martian restaurants. My brother used to take me to them all the time. He always says there's nothing like Martian cooking."

"Quite right." Admiral Yobo stopped glowering and nodded. "Quite right. Your brother has good sense."

"That has nothing to do with anything, Admiral," said Gidlow. "The cadet will have to leave school and come with me. I'll find out what he knows."

"I can't leave school," said Jeff. "The semester is almost over, and I've signed up for summer school so I can learn advanced robotics and invent a hyperdrive."

Gidlow sniggered. "With your record, you'll probably use the hyperdrive to send Space Command into the Sun. No one's invented a hyperdrive, and no one ever will. And if anyone ever does, it won't be a numbskull like you. You're not going back to school, because you're suspended-permanently, I hope."

Yobo said very quietly, "Am I not the one to make that decision?"

"Yes, Admiral," said Gidlow. "But under the circumstances, you'll find you can't make any other decision. Where matters of security are concerned-"

"Please," Jeff said faintly, "it was all an accident." The dark, paneled walls of the admiral's private office seemed to be closing in on him, and Gidlow seemed to be getting bigger and grayer.
