2. Blood on Bronze

Fang Qing arrived with the dawn, bringing the smell of antiseptic and old books.

Lin Xiao watched her step out of the institute's jeep, a compact woman in her late thirties with grey-streaked hair pulled back in a severe bun. She carried a field kit in one hand and a thermos of black coffee in the other, and she moved through the camp with the quiet authority of someone who had spent more time with the dead than the living.

"You look terrible," she said, by way of greeting.

"There's a jade pendant in my tent that vibrates without being touched, and the locust trees are blooming in October. How should I look?"

Fang Qing took a long sip of her coffee. "Like a man who needs a rational explanation. Show me the bones."

The pit had been covered overnight with a temporary shelter, but the locust petals had still found their way inside. They lay scattered across the tarps like small white coins, and Lin Xiao noticed that Fang Qing stepped around them carefully, as if she were avoiding cracks in a sidewalk.

The skeletons had been left in situ, exactly as they had been found. Fang Qing knelt beside the first one, the one with the jade pendant and the broken neck, and opened her kit.

"Cervical fracture at C3 and C4," she murmured, her gloved fingers tracing the vertebrae. "The hyoid bone is intact. This wasn't a hanging."

"That's what I thought."

"It's more consistent with a manual strangulation. But there's something else." She pointed to a series of small, parallel scratches on the anterior surface of the cervical spine. "These are tool marks. Someone used an instrument. A garrote, maybe, or a thin cord with something hard tied to it."

"Execution?"

"Ritual execution. This was done slowly, with precision. The angle of the fracture suggests the killer was behind him, pulling upward. He would have been conscious for at least thirty seconds."

Lin Xiao felt his stomach turn. The Tang Dynasty executioners had used a variety of methods, but ritual garroting was not one he had encountered in the historical records.

"There are seven more skeletons," he said. "Same cause of death?"

Fang Qing moved to the second body, then the third. Her expression remained neutral, but Lin Xiao saw her hands tighten around her tools.

"Identical," she said. "All eight. C3-C4 fracture. Tool marks on the cervical spine. Bodies posed post-mortem in a crouching position. This wasn't a public execution. This was something else entirely."

"A cover-up."

Fang Qing looked up at him. "That's your theory?"

"The bamboo slips we found suggest some of these men were undercover loyalists. Framed by Cui Guangyuan."

"Interesting." Fang Qing stood up and peeled off her gloves. "But you're missing something, Lin Xiao. If Cui Guangyuan wanted to cover up his own collaboration, why would he go to the trouble of a ritual execution? Why not just kill them quickly and dump the bodies? This level of staging suggests something more."

"Like what?"

"Like guilt. Or fear. Or both." She nodded toward the edge of the pit, where Cheng Fei was supervising the excavation of a new section. "Your site supervisor found something. You should look at it before the light changes."

Cheng Fei had uncovered a bronze mirror.

It was large, nearly forty centimeters in diameter, and astonishingly well-preserved. The reflective surface was tarnished to a deep green-black, but the back was intricately carved with a scene of courtiers kneeling before an empty throne.

"It was buried beneath the eighth skeleton," Cheng Fei said. "Placed face-down, directly under the body's chest. As if someone wanted it pressed against the heart."

Lin Xiao knelt beside the mirror. The craftsmanship was extraordinary, the kind of work that would have been commissioned by the imperial household or a high-ranking minister. The kneeling figures were rendered in exquisite detail, their robes flowing, their heads bowed.

"The throne is empty," he said.

"I noticed that too. Usually, these mirrors show the emperor seated, with officials paying homage. This one is different. It's as if the emperor is absent. Or has been removed."

A cold wind moved through the pit, stirring the locust petals at their feet. Lin Xiao looked up and saw that the sky had clouded over, the autumn sun reduced to a pale smear behind a veil of grey.

"Have you cleaned the reflective surface?" he asked.

"Not yet. I wanted you to see it in situ first."

"Let's do it now. Carefully."

Cheng Fei called over one of the junior conservators, a nervous young man named Zhao something, and together they lifted the mirror onto a padded tray. The reflective side was almost completely obscured by a thick layer of corrosion, but as Cheng Fei began to wipe it with a soft brush, something strange happened.

The corrosion flaked away too easily. Beneath it, the bronze was smooth and bright, almost as if it had been polished recently.

"That's not possible," the conservator said. "Bronze oxidizes. It should be rough, pitted. This is..."

He trailed off. Lin Xiao leaned closer.

The mirror was reflecting the pit behind them, but the reflection was wrong. Instead of showing the excavation site, the tarps, the floodlights, it showed a scene that could not possibly exist. A line of kneeling figures in Tang Dynasty robes, their hands bound behind their backs, their heads bowed. And standing behind them, a man in official robes, holding a thin white cord.

There were eight figures kneeling. And the man with the cord was moving down the line, one by one.

Lin Xiao blinked. The reflection flickered. For a single, impossible moment, he saw the face of the executioner.

Then the mirror went dark, and the only face staring back at him was his own, pale and wide-eyed in the dim light.

"Did anyone else see that?" he asked.

No one answered. Cheng Fei was standing frozen, her brush still raised. The conservator had backed away, his hands trembling.

"I saw it," Cheng Fei whispered. "The man with the cord. I saw his face."

"What did he look like?"

"Like you," she said. "He looked exactly like you."

The camp went quiet after that.

Lin Xiao ordered the mirror sealed in a lightproof container and locked in the equipment tent. He told the crew to take the afternoon off, to rest, to not talk to anyone about what they had seen. Then he went to find Shen Mo.

The old epigrapher was in his tent, surrounded by bamboo slips. He had arranged them in chronological order, or what he believed to be chronological order, and was transcribing the characters onto graph paper with a mechanical pencil.

"Professor Shen," Lin Xiao said. "I need to ask you something."

Shen Mo looked up. His eyes were bloodshot, and his hands were shaking more than usual. "The slips from the third skeleton," he said. "They mention a mirror. A bronze mirror given to the condemned men on the night before their execution. It was supposed to show them their true reflection. Their true guilt or innocence."

"Did it work?"

"According to the slips, it showed them something that drove them mad. One of them wrote that he saw his own execution before it happened. Another wrote that he saw his children being killed, even though they were safe in a distant province." Shen Mo removed his glasses and rubbed his eyes. "The mirror was a tool of psychological torture, Lin Xiao. It was designed to break them before they died."

"Who designed it?"

"Cui Guangyuan. He commissioned it from a Buddhist artisan who specialized in ghost-catching mirrors. The kind that were supposed to trap spirits."

Lin Xiao sat down heavily on a camp stool. The weight of the morning pressed down on him like a physical force.

"Why would Cui Guangyuan want to torture them psychologically before executing them? If he was just covering up his own guilt, why go to all this trouble?"

Shen Mo was silent for a long moment. When he spoke, his voice was very quiet.

"Because he wasn't just covering up guilt. He was trying to erase something. Something the condemned men knew. Something that would have destroyed him if it ever came to light."

"What?"

"I don't know yet. But the slips are starting to form a pattern. The eight men buried here were not random traitors. They were a specific group. All of them served in the same ministry. All of them had access to the same information. And all of them were killed on the same night, in the same way, and buried in the same pit."

"A purge within a purge."

"Exactly. Cui Guangyuan executed hundreds of surrendered officials. But these eight were special. They were silenced for a reason." Shen Mo picked up a bamboo slip and held it out. "Read this. It's from the fifth skeleton. The one we've tentatively identified as a man named Wang Li, a mid-level clerk in the Ministry of Revenue."

Lin Xiao took the slip. The characters were tiny but precise, written with a steady hand.

We saw the ledgers. We saw the payments. We saw the name of the man who betrayed the city to the rebels, and it was not a rebel name. It was one of our own. When we tried to report it, we were arrested for treason. Now we die, and the traitor lives, and no one will ever know the truth.

"Cui Guangyuan," Lin Xiao breathed. "He was the one who betrayed Chang'an?"

"Read the last line," Shen Mo said.

Lin Xiao squinted at the faded characters. His blood went cold.

Cui Guangyuan is not the traitor. He is protecting the traitor. The true traitor is someone far more powerful. Someone who still holds the emperor's ear. We cannot write his name. Even in death, we are afraid.

The locust petals began to fall again, drifting through the open flap of Shen Mo's tent like a silent benediction.

That night, Cheng Fei could not sleep.

She lay in her tent, listening to the wind move through the excavation site, and tried to convince herself that what she had seen in the mirror was a trick of the light. A reflection of her own exhaustion. A shared hallucination brought on by stress and the strange atmosphere of the pit.

But she could not forget the face.

It had been Lin Xiao's face. The same cheekbones, the same jawline, the same deep-set eyes. But the expression had been different. Colder. Hungrier. And the man in the mirror had been smiling.

Around midnight, she gave up on sleep and walked to the equipment tent. The bronze mirror was inside its lightproof case, sealed with tamper-evident tape. The tape was intact. The case was undisturbed.

She knelt beside it and pressed her ear to the lid.

At first, she heard nothing. Then, very faintly, she heard something that made her pull back in horror.

Weeping.

Not human weeping. Something older and deeper, a sound that seemed to rise from the bronze itself, vibrating at a frequency that made her teeth ache. It was the sound of someone who had been crying for thirteen centuries and had forgotten how to stop.

Cheng Fei backed away from the case. Her heart was pounding so hard she could feel it in her throat.

She turned to leave the tent.

The mirror case was open.

She had not opened it. The tamper tape was still intact, unbroken. But the lid was off, and the bronze surface was exposed, and in its green-black depths, she saw a reflection that was not her own.

A line of eight kneeling figures. And behind them, a man with a white cord.

The man turned his head. Looked directly at her.

And smiled.

"Who are you?" Cheng Fei whispered.

The mirror did not answer. But the weeping grew louder, filling the tent, filling her head, until she could hear nothing else.

When the junior conservator found her the next morning, she was still kneeling beside the case, her eyes wide open and unblinking, her lips moving silently.

"What are you saying?" he asked, shaking her shoulder.

Cheng Fei turned to look at him. Her voice was hoarse, barely a whisper.

"The mirror knows who the real traitor is. And it wants to show us."
