Rigg sighed at the repetition of the question. “I’ve already told you. I found out the name at the same time I got the jewel—when my father’s letter was opened and read by the friend he left it with. She had no knowledge of the contents, though she obviously knew about the jewel. She had no idea of its value and historical importance, though. No one did, until Mr. Cooper. So if there’s a deception, isn’t he part of it?”

“He insists he is among the deceived.”

“He would, wouldn’t he.”

“Yes—but the jewel most certainly was genuine, so he did not defraud anybody.”

“General Citizen,” said Rigg, “I’ve been thinking back to your summary of my situation, and I can see that either way, I will lose every penny that I have. On the one hand, I’ll lose it because I’m a genuine royal and subject to the laws that apply to that family. On the other hand, I’ll lose it because I’m not royal and therefore am guilty of a crime and, since I can’t name any co-conspirators, will probably be put to death.”

“If it’s any consolation,” said Citizen, “your companions will probably be tortured to death first, in the effort to find out the truth. If neither of them tells who your co-conspirators were or might be, or offers proof that you are not Rigg Sessamekesh, then in all likelihood their deaths without confession will save your life.”

Rigg leapt to his feet. “No! That’s—that’s evil. That can’t be the law! They didn’t do anything wrong! Umbo is a friend from childhood and he came along with me because his father kicked him out of the house. And Loaf is merely a kind man, an ex-soldier and now an innkeeper, and he came with us to keep us safe on the rest of our journey! Why should they die because of that?”

“But my lad, don’t you see? The only evidence we have of their innocence is your insistence on it—and the very point at issue is whether you can be believed or not.”

Without another word, Rigg bolted for the door to the cabin, but when he tried to pull it open, he found Citizen’s hand, above his head, was keeping it closed.

“You don’t really think I’d let you warn them, do you?” asked Citizen.

Rigg sat back down and fell silent. At least he knew his legal dilemma. But what he did not know was how to keep his friends safe. He couldn’t warn them. And yet . . . he knew that Umbo must live, at least long enough to come back from the future and give him the warning by the carriage near the Tower of O. Didn’t that mean that he not only would live, but would also remain in O? And Loaf must live and still be with Umbo, or why would future-Umbo have told Loaf to hide the rest of the jewels?

It was not possible that Loaf and Umbo would be tortured to death. And if that was so, then in all likelihood they would make their escape right now, while the boat was still at the dock.

There was a lurch, and the boat began to move.

All right, then, Umbo and Loaf must leap from the boat and swim to shore.

“You seem curiously untroubled by the movement of the boat,” said Citizen. “What do you know that I don’t know?”

“The movement of the boat,” said Rigg, “is not a surprise. That’s what I assumed it would do from the moment I got on it. That’s what boats are for.”

“But you were certainly calculating that your friends would try to escape while the boat was still at the dock.”

“Why are you so sure of what I was ‘calculating’?”

“Because the dock was the only place where they’d have a crowd to disappear into, where they could use their feet to run away. And, despite your skill at concealing your emotions, you still betrayed just a bit of it. Enough for a trained player of blackstone to detect it.”

“Then you aren’t very good at it,” said Rigg. “Because I definitely felt surprise when the boat moved. If you can read emotions at the gaming table, surely you can detect that.”

“Surprise, yes, but you were not troubled. Your worry dissipated instantly.”

“I don’t believe you’ll really kill them.”

“Oh, believe it, I won’t.”

“I’m glad to hear that,” said Rigg, allowing himself to feel a tiny trace of relief.

“Don’t try to fool me by letting yourself seem relieved. You can’t feel relief if you didn’t feel tension, and you didn’t. Besides, I won’t kill them or torture them because it’s not my job—the Revolutionary Council have specialists who handle all the judicial torture. I’m about fetching you; they’re about opening you up to examination.”

Rigg didn’t allow the implications of that—the hint that he, too, might be tortured—to enter his emotional consciousness. “I’ve been curious as to why a general would be sent to arrest me. Are you considered so worthless to the People’s Revolutionary Council that they would send you on a trivial errand like this?”

General Citizen laughed then. “You really are naive. I truly believe that. Because if you’re pretending, the things you pretend not to understand are so . . . stupidly chosen.”

“Again, I express my ingratitude to my father for the poor design of my education.”

“The reason I was sent to get you is because I maneuvered very carefully to win the assignment. And that’s because there are controversies centered on the Sessamoto Empire older and deeper than the mere matter of the royal family being deposed and the Revolutionary Council being in charge of the World Within the Walls.”

“I have no idea what you’re talking about,” said Rigg.

“It was the decree of Aptica Sessamin, the grandmother of the current non-queen, that only women could rule in the Sessamoto Empire. She gave this decree force by having all her male relatives killed. This put an end to a great many plots centered around removing her—a woman—from the Tent of Light.”

“Tent?” asked Rigg.

“Officially, every royal residence is the Tent of Light when the ruling monarch is in it. Aptica Sessamin murdered all her own sons, as I said, and her reigning daughter, Mutash Sessamin, had only the one child, a daughter, Hagia Sessamin.”

“Hagia—the one who is either my mother or not?”

“So you do know the names of the royal family!”

“Of course I know it now,” said Rigg. “It’s been whispered by half the people we met. ‘He claims he’s the son of Hagia Sessamin.’”

“Cleverly done,” said Citizen. “I was very careful never to mention her name, in case you came up with it. But yes, I did hear the same comments, though I wouldn’t have thought you’d—never mind, I shouldn’t underestimate your cleverness or your powers of observation.”

Rigg showed absolutely no response to this—but by now he understood that to Citizen, not showing a response was, in fact, a response.

“So when Rigg Sessamekesh was born, the first male royal since the death of Aptica Sessamin, the very fact that he was given the suffix ‘ekesh’ was very controversial. That was the suffix given to the male child who was the heir presumptive, back in the days when males ruled. Hagia Sessamin claimed that the suffix only meant that he was the firstborn male child. Since by then the People’s Revolution had made sure there was nothing any royal child, still less a male one, could inherit, the name obviously had no implication of being heir. Others thought he was being named thus to stir up revolt and restore royal power. Still others thought that she was repudiating the law, started by her grandmother, that the Tent and the Stone must pass mother to daughter.”

“Tent and stone?” asked Rigg.

“Yes,” said Citizen. “The Tent that kept alive the memory of the days when the Sessamids were nomads, and the Stone, lost for thousands of years but still revered—its place symbolically taken by a common river rock—which you so kindly offered for sale.”

Rigg said nothing, for his thought now was upon the eighteen other stones, wondering why, when he stood there in Mr. Cooper’s office, he had managed to pick the one that would get him in the most trouble.
