Akzu was staring at the ground. He had seen the path mentioned by Ko. The liquidation of Red Stone clan. Shan remembered the agony on his face when he had heard how their children would be sent to memorize Party scriptures.

"You'll see, comrade. We only want to help. If the Poverty Scheme doesn't work, come and tell me," Ko said, resting his hand on Akzu's shoulder again, then stepped to the vehicle that Jakli had been about to drive away. He opened the door and gestured for Shan to step inside. "Meanwhile," he said, looking at no one but Jakli. "You and your special friends no doubt have important business. Do not let us delay you."

Ko kept smiling. He seemed very pleased to have discovered Shan, Jowa, and Lokesh. Pleased, and not at all interested in stopping them or intimidating them. And that, more than anything, scared Shan.

As Jakli and Jowa moved around to the driver's side, the Tibetan teacher followed them, wearing an uncertain, nervous expression.

"Why are you here?" Jowa growled to the man, in Tibetan.

"I am a teacher. I told you," Kaju replied in Mandarin.

"I mean here, today, in this garage."

Kaju looked back at Ko. "I asked to come," he said in Mandarin, refusing to reply in the language in which Jowa addressed him. "Here, in the shadow of the Kunlun, there are places to hide. I want to explain how hiding helps no one."

Jowa's eyes narrowed, more suspicious than ever.

"Who's hiding?" Jakli asked, watching Ko, who was leaning against his own truck now, out of earshot, still wearing his satisfied smile.

"Maybe not hiding. Running away, perhaps. Maybe you could help."

"Who?" Jakli pressed.

"The children, of course. The orphans," Kaju said. "Lau's children. My children now. We have to reach out to them, help them understand why they have a new teacher, why they must move on. Dealing with death is a learning experience too."

The flash of anger in Jakli's eyes was unmistakable.

"I want to help them," Kaju offered, "We can't stop the classes, or we will lose them, lose all her good work. But only half came to the last session after her disappearance. We must all strive against distrust."

A special university program, Ko had said, Shan recalled as he watched the Tibetan. Kaju had clearly mastered the vocabulary. He wondered if the Tibetan was capable of conducting a conversation without resorting to political slogans.

Jowa pushed Jakli into the driver seat and shut the door behind her. He stared at Kaju. "Because they're being killed, you bastard," he said under his breath, in Tibetan, so low that Shan barely heard.

But Kaju had heard. His jaw dropped open. His face paled. He stood there, confusion gripping his face as Jowa and Lokesh climbed into the back of the truck. Jakli eased the vehicle out of the bay and was halfway across the garage yard when she slammed on the brakes. Another vehicle was emerging from behind the poplars that lined the road, a boxy black sedan. With a sinking heart Shan recognized the car. A Hong Qi, a Red Flag limousine, perhaps fifteen years old, the kind passed on to senior officials in remote corners of China after being retired from use in the eastern cities. Jakli made a small choking sound and her hand jerked to the door handle as if she were going to run.

They watched as the limousine stopped directly in front of the Brigade truck, as though to block it. A brawny young Han man climbed out of the driver's seat, then opened the rear door. A woman wearing a dark blue business suit emerged. She was in her forties, with the high cheekbones and broad face of northern China. Her eyes were hard, her mouth set in what looked like a well-used expression of disdain, and her hair was tied in a tight knot at the back of her head, underscoring the severe cast of her face.

Shan watched Ko Yonghong as he stared sourly at the new arrivals and uttered something to Kaju that caused the Tibetan to disappear into the shadow of the garage. Then, as the woman turned toward him, a cold smile rose on his face and he gave a small nod of greeting.

Shan looked back at Jakli, who still stared nervously at the woman. He did not need to ask her who the woman was. The Jade Bitch. Prosecutor Xu Li.

"You said she was using Lau's death," Jakli whispered. "What did you mean?"

"Picking up Lau's acquaintances. Erecting checkpoints. It's a campaign, not an investigation. I knew a senior Party member in Beijing who said that crime should never be seen as a social problem but as a political opportunity, and that murder was the best opportunity for any law enforcement official."

"Opportunity?"

As they spoke neither moved their gaze away from Prosecutor Xu. She stood beside her car, looking at Ko Yonghong expectantly, waiting for him to come to her.

A third figure climbed out of the Red Flag. A lean man with a pockmarked face, wearing a trim grey uniform bearing four pockets on his jacket. A officer of the Public Security Bureau.

"Sui," Jakli hissed. "Lieutenant Sui. From the barracks in Yoktian."

"There was a murder in Beijing years ago," Shan continued, watching the knob officer as he spoke, "a youth without a job who stabbed a street vendor, an old man who sold noodles. The killer was arrested at the stand, eating a bowl of noodles beside the body, blood on his shirt. But after a week of analysis Public Security announced that the vendor had been from a family of landowners and that he had failed to state this when his family background was requested on his license application. A political review had been conducted, and it was concluded that the vendor had still been victimizing society by lying to get a license, that his antisocial deception inevitably attracted violence. Citizens were invited to amend their registration forms to correct incomplete data or, better still, to inform on any other former landlords who tried to conceal their class history. Long essays in party newspapers, speeches on television. Thirty or forty were arrested and sent to prison."

His gaze drifted toward Ko. The sour expression was gone. He was glaring at the knob officer with obvious resentment. Ko did not like Public Security, or at least did not like Lieutenant Sui.

The knob officer stood at Xu's side for a moment, surveying the compound with a predator's eyes, then stepped into the shadow of the garage.

"But the killer was punished, surely," Jakli said.

"Sent to work camp for a year, for not having a residency permit."

"This is different. Lau's death was not political."

"Her death?" Shan asked. "You said the prosecutor doesn't even know she's dead for certain. All she has is a report of her disappearance." A movement at the end of the garage caught Shan's eye. Akzu was quietly leading his horse around the building, behind Xu's back. "What is her biggest political complaint?"

"The border clans. She says they are irresponsible. They foment unrest. They're reactionary."

Shan nodded his head grimly. "Lau was a teacher. A moderating influence. Trying to bring the orphans of the clans into the social fold. So the border clans thought of her as an enemy."

"Impossible! She was one of us. Never did we-"

"By failing to engage in the socialist dialectic," Shan persisted, explaining the likely mindset of the prosecutor, "the border clans have cut themselves off from the moral nourishment of the state. They breed animosity and social irresponsibility." As he spoke Shan continued to look at Xu. "She must hope Lau is dead. Proof that the clans are destructive of society and must be eliminated."
