3. Blood in the Family Hall

Peking had changed in the three days Yunsheng had been gone. Or perhaps he had changed, and the city was only reflecting what he had become. He entered through the Xizhimen Gate at dawn, his clothes stiff with road dust and his stomach hollow, and found the streets humming with a tension he had not noticed before. The newspaper vendors were shouting headlines about General Zhang's latest conscription drive. The teahouses were full of men who spoke in lowered voices and watched the door. The grey-uniformed soldiers seemed more numerous, their eyes harder, their rifle barrels cleaner.

Liulichang, the antiques district, was quiet when he reached it. Fan's Antiquities still stood with its shutters drawn, a white paper pasted across the door announcing the owner's death and the shop's closure. No one had removed the bloodstain from the workshop floor. Yunsheng stood in the doorway of the abandoned shop and breathed the familiar scent of sandalwood and bronze, now tinged with the copper undertone of old violence.

The floorboard was still in place. He knelt and pried it up with trembling fingers. The oilcloth bundle was there, exactly where he had left it. He unwrapped it and found the Appraisal Codex, its leather cover cool against his palms, its geometric pattern shifting in the grey morning light.

The book had not been taken. Which meant the book Vance had found in the Forest of Stupas was a duplicate. A copy so perfect it had fooled a man who had spent decades searching for the original. But who could have made such a thing? And why had it been placed where Yunsheng's lie had predicted it would be?

He tucked the real Codex into his coat and stood. He needed to find Arthur Morrow. The old scholar had vanished into the hutong the night of the raid, and Yunsheng had no idea if he had survived. But Morrow had said he had been tracking Vance for years. A man like that would have resources. Contacts. Safe houses. And he would not abandon Peking while the Codex was still in play.

The British Legation seemed the obvious place to start. It occupied a sprawling compound in the Legation Quarter, a fortress of European architecture surrounded by walls and guards. Yunsheng had never been inside. Chinese faces were not welcome there unless they were servants or supplicants. But he had no better idea.

He was halfway to the Legation Quarter when a hand closed on his elbow and drew him into an alley.

"Don't scream," Arthur Morrow said. His voice was weaker than Yunsheng remembered, and his face was grey with exhaustion. His scholar's robe was torn at the shoulder, and there was a fresh bruise blooming along his jaw. "Vance's men are everywhere. They are looking for you."

"I thought they had the book. Why would they be looking for me?"

"Because they have discovered that the book they took from the temple is a forgery. A brilliant forgery, but a forgery nonetheless. Vance is not pleased." Morrow leaned heavily on his walking stick. "I need to sit down."

Yunsheng led him to a small dumpling shop at the end of the alley. The owner, a stout woman with flour-dusted hands, looked at them suspiciously but said nothing. In Zhang Zongchang's Peking, asking no questions was a survival skill.

"Tell me what happened," Yunsheng said when they were seated in a corner, steam from the dumpling baskets wreathing their faces.

Morrow took a long breath. "After you left with Vance, I retrieved the Codex from the floorboard. I had been watching the shop since Fan's murder, waiting for a chance to recover it. But when I examined it more closely, I realized something extraordinary. The book is not one document but two. The original 17th-century treatise is interleaved with a second text, written in the same hand but clearly a later addition. A commentary on the practical applications of the Algorithm."

He reached into his coat and produced a sheaf of papers. "I copied the relevant passages before I hid the original. Listen to this."

He read aloud, translating as he went. "'The Algorithm reveals not only the desire but the architecture of its fulfillment. A subject whose hidden desire is for paternal approval will seek objects that symbolize legitimacy. A subject whose hidden desire is for revenge will seek objects that represent power over the target. By crafting the flaw to match the architecture, one may direct the subject's actions with precision.'"

"It is a manual for manipulation," Yunsheng said.

"It is worse than that. It is a manual for destruction. The commentary describes a series of experiments. In each case, a calibrated object was introduced into a household or an institution. In each case, the object triggered a cascade of events that led to the collapse of the household or the institution. The author called this 'the ruin pattern.' And he was very proud of it."

Morrow slid the papers across the table. "Vance has been using the commentary, not the original treatise. He knows how to create the ruin pattern. And he has already deployed it."

"The Liangs and the Zhengs."

"Yes. The two families are connected by marriage, by business, and by a generation of mutual resentment. The Liang patriarch and the Zheng patriarch were rivals in the Qing court. Their children were married to seal a peace that neither side truly wanted. The porcelain brush washer I told you about—it has been placed with the Liangs. A bronze ritual ding of matching quality has been placed with the Zhengs. Both pieces contain calibrated flaws. Both are designed to trigger specific desires in specific family members."

"What desires?"

Morrow's expression grew grim. "The brush washer's flaw is a crack that runs from rim to foot, almost invisible. According to the Codex, a crack of that nature triggers the 'Desire of Legacy' in a subject who fears his inheritance will be stolen. Liang Zhenyu, the eldest son, is that subject. He has spent his entire life preparing to inherit the family fortune. His deepest fear, the one he cannot admit even to himself, is that his brothers will somehow deprive him of what he believes is rightfully his."

"The crack will make him see that fear everywhere."

"Precisely. He will become paranoid. He will see conspiracies where none exist. He will turn on his brothers before they can turn on him." Morrow paused as the dumpling woman refilled their tea. "And the bronze ding's flaw is different. A subtle asymmetry in the taotie mask on its side. The left eye is fractionally larger than the right. According to the Codex, this triggers the 'Desire of Judgment' in a subject who secretly believes he is morally superior to his family. Zheng Jinxiong, the second son of the Zheng family, is that subject. He is a reformist, a modernizer, a man who despises the old ways that his father represents. The ding will make him see his father's corruption in everything the old man does."

"And when the two families collide?"

"They will destroy each other. The Zhengs will blame the Liangs for a series of business reversals that are already beginning. The Liangs will blame the Zhengs for the poisoning of the family patriarch, which I believe has already occurred."

Yunsheng set down his teacup. "The patriarch has been poisoned?"

"Liang Shaoqian died two days ago. The official cause is a stroke, but I have sources in the family physician's household. There were signs of arsenic. The eldest son, Liang Zhenyu, has accused his youngest brother of the crime. The youngest brother has fled. The second son has barricaded himself in the family library and refuses to speak to anyone. The family is tearing itself apart exactly as the Codex predicted."

The dumpling shop seemed to grow colder. Yunsheng thought of the abbot's words at Tanzhe Temple. The Liang family was a house of cards, waiting for a wind. Vance had provided the wind.

"We have to warn them," Yunsheng said.

"Warn them of what? That their own hidden desires are being used against them? They would not believe us. They would think we were mad, or worse, that we were agents of their enemies. The Codex works because people do not want to see the truth about themselves. That is the genius of it. It exploits the gap between what we are and what we pretend to be."

Morrow took a dumpling from the basket and ate it slowly, as if the act of chewing helped him think. "There is something else. Something I have not told you."

"What?"

"The duplicate Codex. The one Vance found in the Forest of Stupas. I did not place it there. I could not have—I was still in Peking, retrieving the real Codex from the shop. Someone else put that duplicate in the stupa. Someone who knew what story you would tell, and prepared for it."

Yunsheng had been turning this over in his mind since the temple. "Who else knows about the Codex?"

"That is the question. The original author, the Jesuit mathematician, died in disgrace. His work was suppressed. The only copies were sent to the mission at Wutaishan. The temple was looted last year, and the bronze vessel containing the Codex was stolen. It eventually made its way to Fan Laoban. But there is a gap in that history. A year between the looting and the appearance of the bronze in Beijing."

"You think someone else found it first."

"I think someone else has been using it for longer than Vance. Someone who knows the Algorithm well enough to create a duplicate that fooled him. Someone who has been watching this entire affair from the shadows." Morrow leaned forward, his voice dropping to a whisper. "And I think that someone is about to reveal themselves."

Before Yunsheng could ask what he meant, the door of the dumpling shop opened. A young man stepped inside, dressed in a Western suit that was clearly expensive but slightly too large for his thin frame. His face was pale and haggard, his eyes red-rimmed from sleeplessness or grief. He looked around the room, his gaze settling on Morrow.

"Mr. Morrow," he said. His voice was educated, the Chinese of a man who had studied abroad. "I was told I might find you here."

Morrow straightened. "Mr. Liang Zhenming. The second son. I did not expect you to seek me out."

"I did not expect to seek you out." Liang Zhenming sat down at their table without waiting for an invitation. "But my family is falling apart, and no one will tell me why. My father is dead. My elder brother has locked himself in the family vault with the porcelain brush washer he purchased last week. He speaks to it. He tells it things. My youngest brother has vanished. The household staff whisper that we are cursed."

He looked at Yunsheng, then back at Morrow. "I am a scholar. I do not believe in curses. But I believe in patterns. And I have noticed a pattern. Three weeks ago, my brother acquired the brush washer. Two weeks ago, the Zheng family acquired a bronze ritual vessel. One week ago, my father fell ill. Yesterday, Zheng Jinxiong, the second son of the Zheng family, publicly accused his father of embezzling funds from the family business. The accusation was baseless, but it has thrown the Zheng household into chaos. Both families are unraveling. And the only common factor is the antiques."

Yunsheng stared at the second son. Here was a man who had looked at the ruin around him and seen not a curse but a design. A scholar's mind, trained to recognize patterns. And unlike his brothers, he seemed to have no hidden desire that the antiques could exploit. Or perhaps he did, and it was simply not the desire Vance had targeted.

"Tell me about the brush washer," Yunsheng said.

Liang Zhenming turned to him. "Who are you?"

"An apprentice. My master was killed by the man who sold your brother that brush washer."

Something flickered in the second son's eyes. Recognition, perhaps, or fear. "The foreigner. Vance."

"Yes."

"Then you know what he is." Liang Zhenming's hands were trembling. "I tried to warn my brother. I told him the price was too high, the provenance was suspicious, the dealer was untrustworthy. He would not listen. He said I was jealous of his position as heir. He said I wanted the brush washer for myself. He has always believed that about me. That I covet what he has."

"Perhaps he believes it because it is true," Morrow said quietly.

Liang Zhenming was silent for a long moment. "I did covet it," he said finally. "Not the brush washer. The inheritance. The position. The respect that my elder brother receives without effort while I, who have studied and traveled and worked, am treated as a second thought. I have resented him for years. But I would never have acted on that resentment. I would never have harmed him or my father."

"But the brush washer changed something," Yunsheng said.

"Yes. I looked at it, the day my brother brought it home. I saw the crack. It was beautiful, in a strange way. A single line running from rim to foot, like a vein in jade. And when I looked at it, I felt something I had never felt before. A certainty. A clarity. I knew, in that moment, that my brother was not fit to inherit. That I should be the heir. That I deserved it."

He pressed his palms against his eyes. "The feeling lasted only a moment. But it was the most powerful moment of my life. And I am terrified that it will return."

Morrow and Yunsheng exchanged a glance. The Codex's method was working with horrifying precision. Even the second son, who seemed so rational, had been touched by the flaw. The desire had been awakened. It was only a matter of time before it consumed him as it was consuming his brothers.

"There is a way to stop it," Yunsheng said. "But you will have to trust us. And you will have to do something very difficult."

"What?"

"You will have to look at your own desire without flinching. You will have to understand the flaw in yourself before the flaw in the antique can destroy you."

Liang Zhenming lowered his hands. His eyes were wet but steady. "Tell me what I must do."

Outside the dumpling shop, the morning had turned to afternoon. The streets of Peking were filling with the usual commerce, the cries of vendors and the rumble of rickshaws. But Yunsheng could feel something shifting beneath the surface of the city. A pattern unfolding. A ruin spreading from house to house, family to family, like cracks in old porcelain.

And somewhere in the shadows, the author of the duplicate Codex was watching. Waiting. Calculating the next move in a game that had been playing for longer than any of them knew.

Morrow unfolded a map of Peking on the table. "The Zheng family residence is in the eastern district, near the Drum Tower. The Liangs are in the western district, near the Prince Gong Mansion. Vance operates from a warehouse in the Legation Quarter. But there is a fourth location I want you to see."

He pointed to a spot on the map, just outside the city walls. "This is the old temple of the White Cloud. It was abandoned after the Boxer Rebellion. But I have sources who say it is being used again. By someone who receives visitors at odd hours. Foreign visitors. Chinese visitors. Visitors who arrive in closed carriages and leave before dawn."

"Vance?" Yunsheng asked.

"Perhaps. Or perhaps the other player. The one we have not yet identified." Morrow folded the map. "I am too old and too injured to investigate myself. But you are not. If you want to understand what is happening, go to the White Cloud Temple tonight. See who comes and goes. And be very, very careful."

Liang Zhenming stood. "I will go with him. If what you say is true, my family's survival depends on uncovering the truth. I will not sit in my library while my brothers destroy themselves."

Morrow looked at him for a long moment. "Your desire to help is admirable. But the Codex preys on admirable desires as easily as shameful ones. Are you certain you can trust yourself?"

"I am certain of nothing," Liang Zhenming said. "But I am more afraid of doing nothing than of doing the wrong thing. Perhaps that is a flaw. Perhaps it is the only thing that will save us."

The afternoon was fading into evening as Yunsheng and Liang Zhenming left the dumpling shop. The streets were filling with shadows, and the grey-uniformed soldiers were lighting the gas lamps along the main thoroughfares. Somewhere in the distance, a newspaper vendor was shouting the evening edition's headline. Yunsheng caught only fragments: "...Liang patriarch... funeral dispute... younger sons in hiding..."

The ruin pattern was accelerating. And somewhere in the darkness beyond the city walls, the White Cloud Temple was waiting. Yunsheng could feel it like a presence, a weight in the air, a flaw in the fabric of the night.

He touched the bodhi seeds the abbot had given him, still looped around his wrist. They were warm against his skin, smooth with centuries of devotion. He did not believe they would protect him. But they reminded him that he was part of something larger than his own fear. A chain of truth-tellers stretching back through the centuries, each one speaking what they knew into the darkness, each one hoping that someone, somewhere, would hear.

Lin Baishui had been one of them. Fan Laoban had been one of them, in his own quiet way. Now it was Yunsheng's turn.

He walked east, toward the city gate, toward the temple, toward whatever was waiting in the dark.
