11. The Merchant’s Debt

The night had become a living thing, breathing menace through every crack and crevice of the Zhang compound. Yuanlong stood at the main gate, his dagger cold in his hand, his ears straining for any sound beyond the frantic beating of his own heart. The county guards had swept through the neighboring streets with torches and drawn swords, but the city was vast, and a man like Huan Decong—rich, resourceful, and utterly desperate—could vanish into its warren of alleys and safe houses.

Suo Fahui appeared at his side, her face pale but composed. She had donned a dark traveling cloak and carried a small leather satchel. "I have sent the servants to the main hall," she said. "The children are with Lady Cui, and I have barred all the doors to the eastern wing. But Yuanlong, if Huan has bribed one jailer, he may have bribed others. He might have accomplices even now, watching this compound from the shadows."

Yuanlong nodded. "I know. That is why I will not stay here and wait for him to strike. I am going to the county yamen to speak with Magistrate Xu. If we can organize a coordinated search, we can trap Huan before he has time to act."

Suo Fahui grasped his arm. "You cannot go alone. If Huan is waiting for you in the darkness, he will kill you before you reach the yamen."

"I will take Deng Fu and two of the stronger servants," Yuanlong replied. "You will remain here with Mother and the children. Bar the gate behind me and do not open it until you hear my voice—and only my voice. If anyone else claims to be me, it is a trap."

He kissed her forehead and turned to leave. Deng Fu appeared with a stout cudgel and a lantern, flanked by two kitchen hands who had volunteered for the duty. They unbarred the gate and stepped out into the moonlit street. The city was eerily quiet—the curfew had emptied the streets, and the only sounds were the distant shouts of guards and the occasional bark of a dog.

They moved swiftly through the twisting lanes, keeping to the shadows, their footsteps muffled by the packed earth. As they rounded the corner near the Temple of the City God, Yuanlong caught a glimpse of movement in a narrow alley to his left—a flicker of torchlight, then a scuffle, then the muffled cry of a man in pain. He motioned for his companions to halt and crept forward, his dagger ready.

In the alley, he found two county guards grappling with a struggling figure. The figure was short and stocky, dressed in a torn blue robe, and he was fighting with the fury of a cornered boar. As Yuanlong drew closer, he recognized the face—it was Liao Wu, the apothecary who had sold the monkshood to the veiled woman.

"Liao Wu!" Yuanlong called out. "What is the meaning of this?"

The guards released their grip, and Liao Wu slumped against the wall, gasping. "Master Zhang—I am sorry—I tried to run, but they caught me—" He coughed and spat blood—he had taken a blow to the mouth. "Huan Decong came to my shop an hour ago. He forced me at knifepoint to give him a dose of something—a fast-acting poison, I do not know what. He said he would use it on you, on your wife, on everyone in your household. Then he knocked me unconscious and left. I woke up and tried to find help, but the guards found me first and thought I was fleeing."

Yuanlong's blood turned to ice. Huan was not just escaping—he was arming himself with a poison, intending to kill them all in one final act of vengeance. He turned to the guards. "Which direction did he go? Did you see him?"

One of the guards pointed toward the eastern gate. "A man matching his description—short, fat, wearing a dark hood—was seen heading toward the old granaries near the river. We were about to search the area when we found this one."

Yuanlong did not hesitate. "Take Liao Wu to the county yamen and place him under protection. Do not let him out of your sight. And send word to Magistrate Xu that Huan Decong has obtained a lethal poison and is heading toward the Zhang compound. I must return home at once."

He did not wait for a reply. He turned and ran, Deng Fu and the servants following at a sprint. His heart pounded against his ribs, each beat a desperate countdown: if Huan reached the compound before him, if Suo Fahui opened the gate even a crack, if the children were in the path of that poison—the thought was unbearable.

They reached the compound in a quarter of the time it had taken to leave. The gate was still barred, and a single lantern burned above the lintel. Yuanlong pounded on the wood. "Suo Fahui! It is me! Open the gate!"

The bar was lifted, and the gate swung open. Suo Fahui stood on the other side, her face a mask of relief. "Yuanlong—what happened?"

He pulled her inside and barred the gate again. "Huan has poison—he is coming for us. We must move everyone to the main hall and barricade every entrance. No one is to open any door or window until dawn."

The household sprang into action. Servants gathered in the main hall, clutching whatever they could use as weapons—kitchen knives, rolling pins, even a heavy bronze incense burner. Lady Wang knelt beside the children, her lips moving in silent prayer. Lady Cui sat with her two small sons, her face ashen but her eyes sharp and watchful.

Yuanlong positioned himself at the main entrance, his dagger in one hand and a heavy iron poker in the other. He had sent Deng Fu to the roof to watch for any approach. The minutes stretched into an eternity, each tick of the water clock a hammer blow.

Then Deng Fu's voice came from above: "Master Yuanlong—I see someone. A single figure, moving along the eastern wall. He is carrying something—a clay pot, I think. He is heading toward the kitchen door."

The kitchen door—the least fortified entrance, used for deliveries and waste disposal. Yuanlong had secured it with a wooden bar, but a determined man could break through. He signaled to two of the servants and crept toward the kitchen, keeping low and silent.

He reached the door and listened. On the other side, he heard heavy breathing, the scrape of boots on gravel, and the soft clink of a clay pot being set down. Then a voice, low and hoarse: "Zhang Yuanlong—I know you are in there. You have taken everything from me—my wealth, my freedom, my future. I will not leave this city alive, but I will make sure you do not enjoy a single day of what you have stolen."

Yuanlong did not answer. He signaled his servants to flank the door. Then he lifted the bar, slowly, silently, and pulled the door open a crack.

Huan Decong stood three paces away, his face a ruin of fury and despair. In his hands, he held a large clay pot with a wax seal. He raised it as if to smash it against the doorframe, releasing whatever poison it contained. But Yuanlong was faster. He lunged forward, the poker swinging in a low arc, catching Huan's wrist with a sickening crack. The clay pot fell from Huan's grip, and Yuanlong caught it before it could shatter on the ground. He set it aside, then drove his shoulder into Huan's chest, sending the merchant sprawling onto the gravel.

The servants rushed out and pinned Huan to the ground. He struggled, snarling, spitting curses, but he was no match for three able-bodied men. Yuanlong knelt beside him, his dagger pressed against Huan's throat. "You are finished," he said, his voice cold. "You have already been indicted for piracy and extortion. Now you add attempted murder with poison. The magistrate will have no mercy—and neither will I."

Huan's eyes blazed with hatred, but he had no strength left to fight. He went limp, his breath coming in ragged gasps. The servants bound his hands and feet with rope and dragged him into the main hall, where the household stared at the captured man with a mixture of terror and relief.

Yuanlong picked up the clay pot and examined it. The wax seal bore the mark of a crude skull—a symbol used by underground poisoners. He did not open it; he would deliver it to the magistrate's alchemist for analysis. But he knew, with a sick certainty, that whatever was inside was meant to cause a slow and agonizing death—perhaps a dose that would have been added to the evening meal, or to the drinking water.

He turned to his wife. "It is over. Huan is caught. The poison is secured. We are safe."

Suo Fahui stepped into his arms, her body trembling. "I was so afraid—I thought he might get to the children—"

"He did not. And he will never have another chance." Yuanlong held her tightly, his face buried in her hair. The adrenaline was fading, leaving behind a bone-deep exhaustion. He wanted nothing more than to sleep for a hundred years.

But as the night began to give way to grey dawn, a new thought crept into his mind: Huan had been in the county lockup when he escaped. He had bribed a jailer. That meant he had resources and connections outside the prison walls. Who had provided the bribe? Who had supplied the poison? Huan was a fallen man—he should have been stripped of his influence. Yet someone had helped him.

He ordered the servants to guard Huan in a locked room and sent Deng Fu to the yamen with a message requesting a full investigation into the jailer's bribery. Then he sat down in the main hall, his father's tokens still hidden in his robe, and stared at the flickering incense smoke.

His brother was in chains. Huan was bound in the next room. The estate was secure. But the poison in his family's blood—the greed, the suspicion, the willingness to destroy one's own flesh for silver—that poison had not been eradicated. It lay dormant, waiting for the next spark.

He looked at his mother, her face lined with grief. He looked at Lady Cui, clutching her children, her eyes hollow. He looked at Suo Fahui, who had proven herself his truest ally. They had all survived the night. But survival was not the same as healing. And healing would take more than legal victories or captured enemies.

The sun rose over the Zhang compound, painting the rooftops in gold. Yuanlong rose from his seat and walked to the eastern courtyard. The locust tree stood in the corner, its half-lopped branches reaching toward the sky like supplicant arms. He knelt beside it and pressed his palm to the soil—the same soil that had hidden his father's shame, and his father's redemption.

He whispered to the tree: "I will not let this house become a grave. I will rebuild it—not with bricks and beams, but with truth and trust. Even if it takes a lifetime."

The tree rustled its leaves, as if in answer. But as he turned to walk back, he noticed a fresh patch of overturned earth near the base of the tree—earth that had not been there the day before. His heart seized. He knelt again and dug with his hands, his fingers tearing through the loose soil. A few inches down, he found a small wooden box, roughly made, without any markings.

He opened it. Inside lay a single sheet of paper, folded into a tight square. He unfolded it and read the characters, written in a hand he did not recognize: "The poison in your house is not Huan Decong. It is the woman who shares your bed. She has been feeding you lies since the beginning. Look in her jewelry box. Find the vial. Then decide who truly deserves your trust."

Yuanlong read the message three times, his mind reeling. A vial—in his wife's jewelry box. His hand shook as he folded the paper and tucked it into his sleeve. He could not bring himself to believe it—not after everything they had endured together. But the message had been buried in a spot known only to himself and his father's ghost. Who could have placed it there? And why?

He walked slowly back to the main hall, his steps heavy. Suo Fahui was there, overseeing the preparation of morning tea. She smiled at him, her eyes warm. "You look exhausted. Come, sit and rest. I will bring you some refreshing tea."

He nodded and sat, watching her as she moved to the kitchen. His eyes drifted to the bedchamber they shared, where her jewelry box sat on the dressing table. He rose quietly and walked to the chamber. He opened the box—a simple lacquered piece, inlaid with mother-of-pearl. Among the combs and hairpins, nestled in a corner, was a small glass vial, no larger than his thumb, filled with a pale, oily liquid.

He held it up to the light. The liquid shimmered with a faint, iridescent sheen. He did not know what it was, but he knew, with a certainty that froze his soul, that it was not perfume.

He replaced the vial carefully and closed the box. Then he walked back to the main hall, his face composed, his heart a battlefield. He accepted the tea from his wife's hands and took a sip. It was sweet and warm, just as she always made it.

He smiled at her. "Thank you," he said. "You are always so thoughtful."

She smiled back, and for a moment, everything seemed perfect. But behind his eyes, the question burned like a brand: Who is the true poison in this house? And how long had it been seeping into his life?
