Jennifer shivered. She tried to imagine how humanity would war with ninety-five percent of its planets swept clean of life. She also wondered what the Foitani had found important enough to fight about on such an enormous scale. Humans had battled over religion with similar ferocity, but the rise of technology had weakened religion's hold on mankind. Maybe the Foitani had kept their fanaticism after they reached the stars.

Thegun Thegun Nug said, "Analysis of our rations has shown that you may safely eat them. You need have no concern on that score."

"How nice." Jennifer set hands on hips, took a deep breath. "You haven't given me a single reason why I should have the least bit of interest in doing anything for you. And I tell you this: kidnapping me like this has given me an awfully big reason not to."

"You have been on our payroll since the day we enrolled in your class, honored professor," Thegun Thegun Nug said. "We will pay standard journeyman merchant's wages, either in your currency or trade goods?your choice."

"I wasn't talking about money," Jennifer said. "And you have gall, too, putting me on your payroll for something I have less than no interest in doing."

For the first time outside the lecture hall, she succeeded in impressing the Foitan. "Money is not a sufficient inducement?" he said slowly. "I had been given to understand?and nothing I observed on Saugus diminished my understanding?that humans are a mercenary species, willing even, at times, to take arms against their own race or kin-group for the sake of profit."

"Some humans are. This human isn't. Damn you!" Jennifer heard her voice breaking, but could not do anything about it. "I was doing what I wanted to do, at last, after years of not being able to. What right do you have to take me away from that?"

"The right of species self-interest," Thegun Thegun Nug said, "which to us is paramount. I might also point out that, at need, physical coercion is available to force you to our will."

Jennifer's stomach turned to a small, chilly lump of ice. She felt her knees wobble. She was sure, though, that the more weakness she revealed to this inexorable alien, the worse off she would be. She looked up into the Foitan's round, black eyes. "How well do you think I'd do for you if you tortured me into submitting?"

"Less well than if you cooperate voluntarily, I admit. Torture, certainly, would be a last resort. I am, however, perfectly prepared to take away from you all your possessions and leave you alone in your chamber until ennui induces you to evince a more constructive attitude. My race has been waiting for twenty-eight thousand years. A fraction of another matters little to us."

She had no doubt Thegun Thegun Nug meant exactly what he said. Being bored into cooperation was attractive only in comparison to being tortured. The worst of it was, the trader part of her wanted to go along with the Foitan. No, the traitor part, she thought. But how many merchants had won the chance to trade with the Foitani? If she looked at it the right way?the wrong way, the professorial part of her insisted?that was what she'd be doing, trading her knowledge for their goods, if she did know what the aliens thought she knew. If she couldn't skin them on that deal, she didn't deserve to be a journeyman.

"All right," she said. "If you think I'm worth risking an interstellar war to get, I'll do what I can for you?provided you let me go after I'm done."

"Certainly," Thegun Thegun Nug said at once. "As for risking war with humans, I will only say it is highly unsafe for ships flown by other species to enter Foitani space unescorted. It is not altogether safe for our own ships to fly. Many weapons from the Suicide Wars are in free orbit throughout our former domain, and hard vacuum is an excellent preservative."

"Wonderful," Jennifer muttered. Now all she had to do was worry about hitting a mine that had been floating free since the days when Cro-Magnon man chased woolly mammoths between glaciers back on Earth.

"It is not wonderful, but it is a fact," Thegun Thegun Nug said; none of the three Foitani had much of a sense of humor. "Our detectors should suffice to get us back to Odern, however."

"They'd better," Jennifer said. "If we blow up, I'll never forgive you."

Thegun Thegun Nug started to answer, then stopped and seemed to think better of it. At last he said, "Come. I will return you to your chamber."

"What happens the next time I need to relieve myself?"

"One of us will escort you here. Were our situations reversed, would you trust me unescorted on a human ship?"

Jennifer wanted to say she wouldn't trust the Foitan no matter what. That did not seem politic at the moment, regardless of how true it was. Without a word, she followed Thegun Thegun Nug out of the toilet chamber and back to her own. She thought hard about annoying her captors with toilet calls at every hour of the day and night. With some species, she might have tried it. Her best guess, though, was that the Foitani would simply stop coming after a while, leaving her to foul her chamber. She decided not to risk it.

Aissur Aissur Rus brought her a plastic pouch of food a couple of hours later. She looked at it without enthusiasm. It resembled nothing so much as dry dog food. "This will nourish you, and should cause no allergic responses," the Foitan said.

Of the three aliens, Jennifer thought Aissur Aissur Rus the most open. Hoping he would answer where Thegun Thegun Nug had not, she asked, "Why did you people grab me? What do you think I can do for you, anyhow?"

"As a matter of fact, taking you was my idea," he said.

She stared at him. After liking him the best, hearing that jolted her. "What is it you want from me?" she repeated.

"One of your human sages once said, 'I am a midget, standing on the shoulders of giants.' When we Foitani of the present days look at the deeds of the Great Ones before the Suicide Wars, we are midgets trying to see up to the shoulders of giants. Perhaps you can help us do that. If not, perhaps you can help us see around the giants' bodies to a new way."

Jennifer frowned. Thegun Thegun Nug had evaded her questions. Aissur Aissur Rus seemed to answer openly enough, but the answer did not mean anything to her. "Go away and let me eat," she told him.

"I did not know you required privacy for that," he said.

"I don't require it, but I'd be grateful. I have a whole lot of things I need to sort out in my mind right now. Please."

Aissur Aissur Rus studied her. The Foitan's eyes had no sclera, no iris, no pupil. They were completely black and completely unreadable. At last, without a word, he made the doorway appear in her wall, walked through it, and made it disappear after him.

She ate. The coarse, crunchy lumps in the plastic pouch tasted like what she thought dog food ought to taste like; they came from something that had been meat quite a while ago. She made herself go on eating till she was full.

When she was done, she looked up at the ceiling and said, "I would like something to drink, please." The Foitani had to have electronic eyes and ears in the chamber.

Sure enough, Aissur Aissur Rus brought her a jug a few minutes later. "This is pure water," he said. "You may drink it safely."

"Thank you," Jennifer said. "May I also have water for washing?"

"Perhaps when you go to the toilets, so it will run down into a disposal hole," Aissur Aissur Rus said. "How often do you usually wash? The human custom is once a day, is it not? I suppose that might be arranged."

"You might have thought beforehand about what I'd need," Jennifer said.

"We are not used to considering the needs of other species. It is not the Foitani way, and does not come easy to us."

"Really? I never would have noticed."

Irony bounced off Aissur Aissur Rus as if he were iron-plated. When he saw Jennifer had no more to say, he turned and left as abruptly as he had before. She drank the jug dry. The water was cold, and had the faint, unpleasant untaste of distilling. It did help to ease her headache.
