8. A Pattern in Blood

The footstep did not come again. Li Xun remained motionless against the stone wall, his breathing shallow and silent, his knife held low and ready. The darkness outside the window was absolute, the stars obscured by a band of cloud that had drifted across the sky sometime in the last hour. He listened for a long time, but the only sounds were the wind and the distant howl of the wolf and the soft snoring of the watchman on the tower.

Dawn came slowly, a gray light seeping across the desert like water into dry sand. Li Xun rose, stiff and cold, and stepped outside to examine the ground around the command office. The gravel was disturbed in several places, but the marks were too faint to read clearly. Someone had been there, or the wind had been playing tricks. He could not be certain.

He woke Qian and Zhao and told them to prepare for the journey. The captain gathered his few belongings and distributed weapons from the armory: a short sword for himself, a hunting knife for Qian, and a crossbow that he handed to Li Xun.

"I have not fired one of these in years," Li Xun said, turning the weapon over in his hands.

"Then stay close to me," Zhao replied. "I have spent twenty years practicing on wolves and bandits. I can still shoot straight."

They mounted their camels as the sun cleared the eastern ridges and rode out through the outpost gate. Li Xun glanced back once at the small stone buildings and the sleeping watchman on the tower. He wondered if he would ever see the place again, and decided he did not care either way.

The road south was empty. The desert stretched away on all sides, a vast expanse of gravel and brown earth and occasional tufts of dry grass. The camels moved at their steady, unhurried pace, and the sun climbed higher, and the heat began to build. Li Xun rode in silence, turning over the evidence in his mind, searching for gaps and weaknesses.

They had Zhao's testimony. They had Qian's testimony. They had the forged confessions, the payment records, the letter from the Duke to the prefect, the search order that proved the evidence had been planted. They had the seal fragments and the blue silk thread and the cart that had killed Kang. But none of it directly tied the Duke to the current murders. The Needle was the link, the hidden blade that connected the nobleman to the killings. Without the Needle's confession, the Duke might still escape.

"We need to find Zheng," Li Xun said aloud. "The Needle. He is the only one who can confirm that the Duke ordered the murders."

Zhao shook his head. "You will never take him alive. He has been a killer for thirty years. He knows every poison, every pressure point, every way to end a life. If you corner him, he will either kill you or kill himself."

"Then we must find a way to corner him that he does not expect."

They rode on through the morning. Around midday, they stopped at a dry wash where a few stunted willows offered a thin shade, and they ate a cold meal of millet cakes and dried dates. Qian sat apart from the others, his back against a gnarled trunk, his eyes fixed on the northern horizon as if he expected the Needle to appear at any moment.

"He will come for us," Qian said quietly. "He said three days, but he will not wait that long. He will realize we have left the outpost, and he will follow."

"Then let him follow," Zhao said. "There are three of us and one of him. And I know this desert better than he does."

Li Xun was about to reply when something caught his eye. A thin column of dust rising from the road behind them, miles away but moving fast. A rider on a swift horse, pushing hard through the heat.

"He is already following," Li Xun said.

They broke camp quickly and mounted their camels. Zhao led them off the main road and into a maze of low hills and dry ravines, where the terrain would hide them from a pursuer. The camels grumbled but obeyed, picking their way through the rocky ground with the sure-footedness of animals born to the desert.

They rode for two hours through the ravines, changing direction several times, until Zhao finally called a halt. They were in a narrow canyon with walls of red sandstone rising on both sides. A trickle of water seeped from a crack in the rock, feeding a small pool surrounded by ferns and moss.

"This is a hidden spring," Zhao said. "The locals call it the Ghost's Tears. Few people know of it. We can rest here until nightfall, then continue under cover of darkness."

Li Xun dismounted and drank from the pool. The water was cold and sweet, a gift from the deep earth. He splashed some on his face and felt the grime of the road wash away. Then he sat down against the canyon wall and closed his eyes for the first time in what felt like days.

But sleep would not come. His mind was too full, too restless, too aware of the danger that was closing in around them. He opened his eyes and found Qian sitting beside him, the hunting knife clutched in both hands.

"Inspector," Li Xun said. "When you saw the Duke in the granary, twenty years ago. You said he was arguing with Yuan and the Needle. What were they arguing about?"

Qian frowned, searching his memory. "The seals. The Duke said the carving was too crude, and the Needle said he could not do better without a genuine seal to copy. Yuan said they should abandon the whole scheme. The Duke grew angry. He said he had already invested too much silver and could not afford to lose it."

"He said he could not afford to lose it. Those were his words?"

"Yes. He seemed desperate. Not like a nobleman at all. More like a man who had gambled everything on a single throw of the dice."

Li Xun turned this over in his mind. A young nobleman desperate for money. A forgery scheme that promised quick profits. And then, when the scheme began to unravel, a betrayal that sent two men to their deaths and left the nobleman free to rebuild his fortunes.

"What happened to the Duke's wealth after the trial?" Li Xun asked.

Zhao, who had been keeping watch at the canyon entrance, answered without turning. "He became rich. Very rich. He built his estate, his temples, his granaries. Everyone assumed his family had always been wealthy, but the older merchants say otherwise. They say the Duke arrived in Yizhou with almost nothing, the younger son of a minor branch. His fortune was made in a single year."

"The year of the trial."

"Yes."

Li Xun felt the pieces locking together. The Duke had financed the forgery ring with borrowed money, or the last of his family's resources. When the scheme succeeded, he used the profits to build his reputation as a philanthropist and community leader. The two forgers who had done the actual work were executed, taking the secret of his involvement to their graves. The witnesses who might have exposed him were silenced with bribes or threats. And for twenty years, the Duke had lived in comfort and honor, his crime buried beneath layers of charity and good works.

But the buried truth had festered. The witnesses had grown old and begun to talk. The records had remained in the archive, waiting for someone curious enough to examine them. And when Li Xun had begun asking questions, the Duke had turned to his old ally, the Needle, to complete the work that the executioner's blade had started two decades ago.

"We have to move before nightfall," Li Xun said suddenly, rising to his feet. "The Needle knows this desert as well as you do, Captain. He may know of this spring. And if he does, we are trapped in this canyon."

Zhao turned from the entrance, his face sharp with alarm. "You are right. I did not think of that. The Needle was the prefectural torturer. He would have interrogated prisoners who knew every hidden path and water source in this region."

They gathered their belongings and mounted the camels. Zhao led them deeper into the canyon, where a narrow path wound upward through the red rock toward the plateau above. The camels climbed slowly, their hooves scraping on the stone, and Li Xun felt the sun beating down on his neck like a hammer.

Halfway up the path, he heard it. A sound that did not belong to the desert. The sharp, metallic click of a crossbow being cocked.

"Down!" he shouted, and threw himself from his camel's back.

The bolt struck the rock where his head had been a moment before, shattering against the sandstone in a spray of splinters. Li Xun hit the ground hard and rolled behind a boulder. Zhao had dismounted as well and was crouched behind another rock, his own crossbow raised and searching for the shooter. Qian was still on his camel, frozen with terror, the hunting knife useless in his hand.

"Qian, get down!" Li Xun shouted.

The grain inspector slid from the saddle just as a second bolt whistled through the air where his chest had been. He landed in a heap on the path and scrambled behind the nearest cover.

For a long moment, nothing moved. The sun beat down. The wind whispered through the canyon. Li Xun pressed his back against the boulder and tried to control his breathing.

"Can you see him?" he called to Zhao.

"Higher up. On the eastern rim. I saw movement, but I cannot get a clear shot."

Li Xun risked a glance around the edge of his boulder. The canyon rim was perhaps fifty paces above them, a jagged line of red rock against the pale sky. He saw no one. But the Needle was up there, patient and invisible, waiting for one of them to make a mistake.

"We cannot stay here," Li Xun said. "He has the high ground. He can pick us off one by one."

"There is another path," Zhao said. "Farther up the canyon, around the next bend. It leads to a narrow crevice that opens onto the plateau. But we will have to cross open ground to reach it."

"Then we provide cover for each other. You first, Captain. You have the crossbow. Find a position and keep him pinned down. Then Qian, then me."

Zhao nodded. He took a deep breath, then burst from cover and sprinted up the path. A bolt struck the ground behind his heels, and another whistled past his shoulder, but he reached the next bend and threw himself behind an outcropping. A moment later, his crossbow twanged, and a cry of frustration echoed from the rim.

"Now, Qian!" Li Xun shouted.

The grain inspector ran, stumbling on the loose rocks, his robes flapping around his legs. A bolt struck the path in front of him, and he veered wildly, but Zhao's covering fire kept the shooter from taking a second shot. Qian reached the bend and collapsed beside Zhao, gasping for breath.

Li Xun was alone now. He judged the distance to the bend. Thirty paces. He could make it in ten heartbeats if he ran straight and fast and did not trip.

He ran.

The first bolt missed his head by a hand's breadth. The second struck the ground at his feet and ricocheted into the canyon wall. He threw himself forward, diving behind the outcropping just as a third bolt shattered against the stone where his shoulder had been.

He lay on the ground, breathing hard, and looked up at Zhao and Qian. Both men were alive, pale and shaking but alive.

"He is too good," Zhao said. "I fired three shots and none of them hit. He is moving along the rim, keeping cover. We will not reach the crevice without losing someone."

Li Xun looked up the canyon. The crevice was still a hundred paces away, a dark slit in the red rock that promised escape onto the open plateau. But between here and there was a stretch of path with almost no cover, exposed to the shooter on the rim.

"Then we do not go to the crevice," Li Xun said. "We go back down. Find another route."

"There is no other route. The canyon dead-ends half a mile ahead. The only way out is up."

Li Xun closed his eyes and forced himself to think. The Needle was one man, moving along the rim, limited by the amount of ammunition he carried. He had already fired at least six bolts. A crossbow could not fire quickly; each shot required time to reload. If they could force him to exhaust his bolts, or if they could find a way to reach the rim and engage him directly...

"There is a third path," Li Xun said slowly. "The spring."

Zhao stared at him. "What do you mean?"

"The spring in the canyon. The water comes from somewhere. It seeps through the rock. There must be a fissure, a weakness in the canyon wall. If we can find it, we might be able to climb up inside the rock, where he cannot see us."

Zhao considered this. "It is a gamble. The fissure might be too narrow to climb. Or it might not reach the rim at all."

"It is a gamble," Li Xun agreed. "But staying here is certain death. He has food and water and ammunition. We have almost nothing. Eventually, we will have to move, and when we do, he will kill us."

Zhao nodded slowly. "Then let us go back to the spring. Quickly, before he realizes we have retreated."

They moved back down the path, keeping low and using the rocks for cover. The shooter on the rim fired twice more, but the bolts went wide, and then they were around the bend and out of sight. They reached the spring a few minutes later, and Li Xun began examining the canyon wall.

The water seeped from a crack near the base of the wall, a dark, damp fissure barely wide enough for a man's shoulders. Li Xun pushed his hand into the crack and felt the rock open up beyond, a narrow vertical chimney that rose into darkness.

"It widens inside," he said. "I can feel a ledge about ten feet up. If we can reach it, we might be able to climb the rest of the way."

"I will go first," Zhao said. "I have the crossbow. If there is anything waiting at the top, I can deal with it."

He squeezed into the crack and began to climb, bracing his back against one wall and his feet against the other. Li Xun watched him disappear into the darkness, his progress marked by the scrape of leather on stone and the occasional shower of loose pebbles.

A long time passed. Li Xun and Qian waited at the bottom, listening. The canyon was silent except for the drip of water and the distant cry of a hawk. The shooter on the rim had stopped firing. Perhaps he was waiting for them to show themselves again, or perhaps he was already moving to a new position.

Then, from high above, Zhao's voice echoed down the chimney. "I have reached the top! The fissure opens onto the plateau. I can see the canyon rim from here. The shooter is still there, waiting. He has not seen me."

"Can you reach him?" Li Xun called back.

"Not without exposing myself. But I can see his position. He is on a ledge just below the rim, reloading his crossbow. He has a small camp there, with supplies. He was prepared for a long wait."

Li Xun turned to Qian. "Can you make the climb?"

The grain inspector looked at the narrow crack, his face pale. "I will try. I would rather fall from a height than die on the ground like a trapped rabbit."

Qian squeezed into the crack and began to climb, his movements slow and clumsy but determined. Li Xun waited until the grain inspector had disappeared into the darkness, then followed.

The climb was harder than he had expected. The rock was damp and slippery, and the chimney was so narrow that he could barely move his arms. He inched upward, bracing his back and feet against the walls, feeling for handholds in the darkness. The air was cold and smelled of wet stone and ancient earth.

He was perhaps halfway up when he heard it. A sound from below, faint but unmistakable. Someone else was entering the chimney.

The Needle had found them.

Li Xun climbed faster, scraping his palms on the rough rock. Above him, he could see a faint circle of light where the chimney opened onto the plateau. Zhao and Qian were already there, their silhouettes visible against the pale sky.

"Hurry!" Zhao shouted down. "He is in the chimney behind you!"

Li Xun reached for the next handhold, but the rock crumbled under his fingers, and he slipped. For a terrible moment, he hung in the darkness, his feet scraping against the walls, his body suspended by the strength of his arms alone. Then he found a new hold and pulled himself upward.

A hand reached down from above. Zhao's hand. Li Xun grasped it, and the captain hauled him out onto the plateau, where he lay gasping in the bright sunlight.

Below them, in the darkness of the chimney, something moved. Something that was climbing steadily upward, unhurried and patient, like a spider returning to its web.

Zhao raised his crossbow and aimed it at the opening. "When he comes out, I will shoot him."

"No," Li Xun said, struggling to his feet. "We need him alive. He is the only one who can testify against the Duke."

"If we wait for him to come out, he may kill us all."

Li Xun looked around the plateau. It was a flat expanse of gravel and dry grass, stretching toward the distant mountains. There was no cover, no place to hide. But there was something else, something that might give them an advantage.

"The ledge," he said. "The Needle's camp. It is below the rim, cut into the canyon wall. If we can reach it, we can take his supplies and force him to come to us on our terms."

Zhao hesitated, then nodded. "I saw it from here. There is a path along the rim that leads down to it. But we must move quickly."

They ran along the rim, keeping low to avoid being seen from below. The path was narrow and crumbly, and Li Xun felt the drop yawning beside him like a hungry mouth. But they reached the ledge without incident, and Li Xun dropped down onto it with Zhao and Qian close behind.

The camp was simple: a bedroll, a waterskin, a small bag of dried meat, and a leather satchel containing a spare crossbow string, a dozen bolts, and a collection of small glass vials filled with dark liquids. Poisons, Li Xun guessed, each one designed for a different purpose. Quick death, slow death, silent death, painful death. The Needle's arsenal.

And beside the bedroll, wrapped in a cloth, was a small stone seal. A complete seal, not a fragment. Li Xun picked it up and turned it over. The carving was crude but recognizable. It was the same military granary seal that had been forged twenty years ago.

"He kept it," Li Xun said. "After all these years, he kept it. The original forgery. The one that started all of this."

"Vanity," Zhao said. "He is proud of his work."

"Or insurance," Li Xun replied. "Proof of the Duke's involvement, in case he ever needed it."

Footsteps crunched on the gravel above them. The three men looked up and saw a figure standing on the rim, silhouetted against the afternoon sun. A small man, with delicate hands and a ring that glittered red on his finger.

"You have found my camp," the Needle said. His voice was soft and refined, the voice of a scholar rather than a killer. "I congratulate you. Most men would have died in the canyon."

"We are not most men," Li Xun said.

"No. You are not. You are Li Xun, the clerk who notices too much. And you have brought Captain Zhao and Inspector Qian with you. How convenient. I can finish all three of you at once."

Li Xun held up the stone seal. "If you kill us, this goes over the cliff. And with it, your insurance against the Duke. Do you think he will let you live once he knows that you kept evidence of his crime?"

The Needle's expression did not change, but his hand tightened on his crossbow. "You do not understand the Duke as I do. He and I have been bound together for twenty years. We are two halves of the same crime. He cannot destroy me without destroying himself."

"Perhaps. But are you willing to test that theory? Are you willing to die because you trusted a man who has already betrayed everyone else who ever worked with him?"

The silence stretched out, thin and taut as a wire. The wind blew across the plateau, stirring the dust and the dry grass. The Needle looked at Li Xun, and for the first time, something flickered in his dark eyes. Something that might have been doubt.

"What do you want, clerk?"

"I want your testimony. I want you to confess to the forgeries, to the murders, and to the Duke's involvement. In exchange, I will recommend leniency to the magistrate. You may not escape execution, but your death will be quick and clean. Not the slow, painful end that the Duke would give you if he knew you had kept that seal."

The Needle laughed, a soft, dry sound. "Leniency. From a Tang court. You are either very naive or very optimistic."

"I am neither. I am a man who has seen what happens when the powerful are allowed to bury their crimes. I am a man who believes that the dead deserve justice, even if it comes twenty years late. And I am offering you the only chance you will ever have to die with a clean conscience."

The Needle lowered his crossbow, but he did not set it down. His eyes moved from Li Xun to Zhao to Qian, and then back to Li Xun. "You are a strange man, Li Xun. Most clerks would have stayed in their offices and copied their ledgers and never asked a single question. But you went looking for the truth. And you found it. I respect that."

"Then help me finish it."

The Needle was silent for a long time. The sun sank lower, and the shadows stretched across the plateau. Finally, he nodded.

"I will give you your testimony. But not here. We will return to Yizhou together, and I will speak before the prefectural court. And when I do, I will name the Duke as my master and my partner in every crime I have committed for the past twenty years."

Li Xun let out a breath he had not realized he was holding. "Then we have an agreement."

"We do. But I warn you, clerk. The Duke will not go quietly. He has allies throughout the town. The Deputy Prefect, the merchant houses, the militia commanders. When you accuse him, you will be accusing half the powerful men in Yizhou. Are you prepared for that?"

Li Xun looked out across the desert, toward the distant town where the Duke was waiting in his garden. "I have been preparing for it my entire life."

The Needle smiled, a thin, cold smile. "Then let us go and wake the dead."
