Shan collapsed his fingers self-consciously, without answering. "Lieutenant Sui," he said. "Are they investigating his murder?"

"Bao's office said he is transferred out, a new assignment in Manchuria."

"But you didn't believe it."

She drew deeply on her cigarette. "It's not that simple."

"Of course it is. Sui is dead, or Sui is transferred. Did you try to verify his transfer?"

She frowned, as if she found the subject distasteful.

"There are two possibilities," Shan suggested. "Public Security is covering up, not telling the Ministry of Justice. Or Bao is covering up, not telling even Public Security." There was another possibility, which he would not give voice to. The killing was known to all, to Bao, to Xu, to Beijing, but not yet politically resolved.

"That day at the motor pool," he added. "Sui was with you, Kaju was with Ko. Kaju said he was looking for the boys, Lau's boys. Maybe Sui was too."

This time when she exhaled she blew the smoke directly into his face. "We were using the roadblocks for the missing person investigation. Public Security was cooperating. The Ministry and Public Security work hand in hand."

"Last time I was with you," Shan returned matter-of-factly, "Public Security was throwing a mug at you." For a second, and only a second, Shan thought he saw something that might have been amusement in the prosecutor's eyes.

"I have another idea about Sui," Xu said. "If he is dead, maybe Tibetans killed him."

Shan felt his throat go dry. He returned her stare and shrugged. "This is Xinjiang."

"This is borderland. This is everywhere and nowhere. When you drove away that day at the motor pool, Sui got on the radio with the roadblocks. He said to detain you. Not you, actually. He gave orders to stop the truck and arrest the old Tibetan with you."

Shan stared into his hands. Sui was looking for Tibetans. Was he the one who had found Lau? Out of the corner of his eye he saw a grey figure rise and slowly walk around the back corner of the garage. Jakli, going to where Lokesh slept.

"A harmless old man," Shan said.

Xu looked toward the Kunlun with a pained expression. "The one word I would never use for Tibetans," she said with a strangely distant tone, "is harmless." She gazed around the compound. "Everyone else we can talk with, we can negotiate with, we can educate, we can teach the wisdom of becoming something else." Her mouth twisted, as if she had tasted something sour. "But the Tibetans," she said slowly, "they just stay Tibetans."

"Which is why you attack prayer flags?" Shan asked quietly.

She silently stared at him for a long time, then looked down at the table. "I know at least one boy died," she said, just as quietly. "Sui implied that Tibetans were involved in some new conspiracy. I asked my investigator to watch, and listen, to find where in the mountains the zheli children might meet Tibetans. We heard about a small family at that place. We went to look. Now you say a boy died at the place," she added, as if it proved her point.

You went to blind the deities, Shan almost said. "You went with Public Security?"

"No."

"Meaning what? That Public Security doesn't care about boys but you do?"

She stared at him coolly without answering.

He pulled the black compass from his pocket, opened it, and placed it on the table. "Do you recognize this? Was it your investigator's? Bao's?"

"Not mine," she shot back resentfully, as if he had accused her of something. Then she stared at the device. "You found it there? My investigator wasn't there, before he went with me. He had just been asking questions, talked to helicopter pilots. It's not his. As for Bao, you'd have to ask him. I can arrange a meeting," she offered with a cool, thin smile.

Shan folded the compass but left it on the table between them.

"What if you had found a boy out there, what would you have done?"

"Take him into protective custody for a few days. Then give him back to the school program."

Shan was silent for a moment, considering her words. "Tell me, Comrade Prosecutor," he said as he pocketed the compass, "do you think Tibetans are guilty, just because Sui was looking for them?"

"Sui. And now Bao. He's erecting random checkpoints throughout the county. Anyone with Tibetan papers is to be held for questioning, even anyone with a Tibetan birthplace. He's rounded up a few old men who couldn't explain their origin to his satisfaction."

The waterkeeper. She had not mentioned the waterkeeper. Because, he hoped, the lama had not been discovered. Maybe he was better off at Glory Camp, maybe he was invisible to Bao at Glory Camp. Though not if he continued to interfere with political officers.

"Because of a poem?" Shan asked. "Does poetry scare Bao so much?"

She frowned again. "Because he is a major in Public Security," she said, meaning Bao could do whatever he wanted. He owned an explanation to no one, including the prosecutor.

She stared at him and seemed to detect the pain in his eyes. "Your friend," she pressed, clearly enjoying his discomfort, "an old Tibetan traveling with a known fugitive. Think of the stories he will have when Bao picks him up."

Just an old man, Shan was about to repeat, but a question overtook his tongue. "Why did he radio the others? Why didn't Sui just take him there, at the motor pool?"

Xu opened her mouth as though to reply, but she had no words. She just looked back toward the Kunlun.

"Because," Shan ventured, "he didn't want Ko to know."

"Sui was angry when the patrols didn't find your friend. Issued a description to them, so he could be picked up later."

"There is another Tibetan," Shan said. "What do you know about Kaju Drogme?"

"I interviewed him before he started. He's different. A model for all the minorities. One of the few Tibetans who has recognized the challenges of balancing the needs of our society. There was a meeting about him, to decide on bringing him here. Ministry of Education. Bureau of Religious Affairs. Public Security. The Brigade."

"Why the Brigade?"

"Of course the Brigade. In this district, the government decides and the Brigade implements. They have a special office in Urumqi for this program, administering fifty or sixty teachers all over Xinjiang, all minorities trained in cultural assimilation. Got the attention of Beijing and of the top managers of the Brigade. The Brigade," she reminded Shan, "is one of the largest companies in China." She thought for a moment and shrugged. "Still, the program's only an experiment."

"You're not convinced."

"He goes too far sometimes. Lau, she was balanced. But this Kaju- I went to one of his classes. He was showing everyone how Buddhist prayer beads work, asking if anyone had beads when they were young. I called the Brigade office to complain. They said it was part of the program. Validate the ethnic roots. Make Tibetan children know it's all right to have beads, make the Muslims know it's all right to bow toward their Mecca sometimes. Then gradually make them see how old-fashioned it is, just a subtle form of mind control."

Shan looked at her without replying. Validating ethnic roots was also one way to identify hidden Tibetans. Mao tse-Tung had launched a campaign over thirty years earlier known as the One Hundred Flowers program. Let one hundred flowers bloom, the chairman had said, as a way of encouraging people to express diverse views, to criticize the government in public. It had been staged as a way of flushing out dissidents. After a few months the campaign was ended and those who had spoken out against the Chairman were arrested.
