3. The Algorithm's Lure

The safety deposit box sat in a vault beneath a bank on Granville Street that had been built when Vancouver still called itself a town. Zhang Qiming led Shen Han past the marble counters and the armed guard who nodded at him with the familiarity of long acquaintance, down a narrow corridor lit by fluorescent tubes that buzzed at a frequency just below hearing. The vault door was circular, black iron, manufactured in Manchester in 1912 according to a brass plaque. It swung open on oiled hinges.

Zhang’s box was number 447. He drew out a flat aluminum case, set it on the inspection table, and did not open it immediately. Instead, he looked at Shen with an expression that had changed since the warehouse. The hardness was still there, but it had acquired a new layer—anxiety, perhaps, or the beginning of trust.

“Before I open this,” Zhang said, “I need you to understand something. My father was not a collector. He was a believer. He believed objects carried the souls of the people who made them, and that owning an object meant accepting responsibility for its history. When he bought this fragment, he told my mother it would bring either a blessing or a curse. She laughed. But after he died, I found a letter in his study addressed to me. It said: ‘The fragment will claim someone before it is returned to the earth. Do not let it be you.’”

Shen said nothing. The hum of the vault filled the silence.

Zhang opened the case. Inside, on a bed of black silk, lay a piece of jade roughly the shape of a crescent moon, the outer edge curved and polished, the inner edge jagged where it had fractured. The surface was the pale celadon of old mutton-fat jade, veined with russet inclusions that traced lines like capillaries. Near the inner rim, a column of characters had been incised with a sharp point, then filled with something dark—lacquer, Shen guessed, or oxidized silver.

He recognized the handwriting before he could read the words. The characters were carved in the distinctive clerical script his grandfather had used in every field note, the horizontal strokes slightly upturned at the ends, the verticals weighted like brushwork. Shen Yansheng’s hand. Unmistakable.

The inscription read: “沈延生見此玉者當歸還墓中否則禍及子孫 — Shen Yansheng, he who sees this jade must return it to the tomb, or calamity shall befall his descendants.”

Shen felt the floor tilt. It was not a curse against those who disturbed the dead. It was a warning, written by his grandfather, addressed to his grandfather. The third-person form was a classical convention, but the intent was clear: Shen Yansheng had carved this message himself, presumably after finding the disc, and had left it as a command to whoever came after.

Or as a confession.

“You said this was a fragment of a bi disc,” Shen said, his voice steadier than his hands. “A bi disc placed on a skeleton’s chest. My grandfather described it in his notes. He said the village elders told him about it. But if he carved this, he must have held the disc in his hands. He must have taken it from the tomb.”

Zhang nodded slowly. “I wondered the same thing. My father bought this from a man named Luo who lived in Hong Kong. Luo claimed he had acquired it from a Canadian missionary who had been in Henan in the 1940s. But the dates do not align. If your grandfather carved this in 1964, how did it leave China before he wrote the notes? Unless the missionary story was a cover for a much more recent transaction.”

“Or my grandfather was in contact with someone overseas before he left China,” Shen said. “He was forced out in 1966. Two years after the excavation. He could have sent objects ahead, or entrusted them to someone who escaped earlier.”

Zhang closed the case. “There is more. The letter my father left me also contained a photograph. I will show you, but not here. This vault has ears, and I do not mean the guard.”

They left the bank and walked six blocks to a teahouse Zhang knew, a narrow room on the second floor of a building that had been a tong hall in the 1920s. The owner greeted Zhang by name and led them to a private booth with walls of carved ebony. Oolong was served. Zhang waited until the door slid shut before he took an envelope from his jacket.

The photograph inside was black and white, faded to sepia at the edges. It showed three men standing before a freshly opened burial mound, the earth dark and raw. Two of the men wore Mao suits and held clipboards. The third man, older, in a Western shirt and trousers, held a fragment of jade—the same crescent shape that now sat in Zhang’s safe deposit box. The older man’s face was tilted downward, shadowed, but the posture was unmistakable. Shen Han had seen that posture in a dozen family photographs. It was his grandfather.

“Who are the other two?” Shen asked.

“The man on the left is Professor Wen Li,” Zhang said. “Younger than you know him. I had the photograph analyzed. The facial recognition software is not perfect, but the bone structure matches at ninety-two percent. The man on the right is unidentified. But look at his hands.”

Shen looked. The unidentified man’s hands were folded in front of him, and on the ring finger of his left hand was a heavy signet ring, its face turned toward the camera. The image was grainy, but the design was visible: a stylized character that could have been “渊”— abyss.

“Abyss Pavilion,” Shen said. “The company behind the algorithm.”

“I think so. I think the Abyss Pavilion has been involved with the Whitewater objects since the moment they left the ground. They were there, at the excavation. They may have been the reason your grandfather was forced out. And they have been waiting, all these years, for someone to come looking.”

Shen set the photograph down. His tea had grown cold. “Why? What do they want?”

“That is the question I have been asking myself since I first saw this picture. I do not think they want money. They have money. The algorithm is expensive to build, expensive to maintain. They are investing in something larger than profit. They are investing in a story.”

“A story about what?”

“About legitimacy. About who inherits the past. The Whitewater tomb had two widows, two sons, and a dispute that could not be resolved. The Abyss Pavilion has spent decades ensuring that dispute remains alive. They sell forgeries to one branch of a family, authentic objects to another, and make sure each side believes the other holds fakes. They fuel litigation. They fund rival auction bids. They keep the wound open because an open wound is profitable, yes, but also because it serves a purpose I do not yet understand.”

Shen thought of the algorithm’s dossier, its careful profiling of his “ancestral guilt index,” its offer to restore narrative authority. The machine had not merely predicted his desires. It had manufactured the conditions under which those desires would become actionable. It had given him a disc to chase, a cup to verify, a Zhang to meet. Every step he had taken since scanning that QR code had been laid out in advance, like stones across a river.

“What about your cousin?” Shen asked. “Where does Qitai fit into this?”

Zhang’s face darkened. “Qitai and I are the two sons. That is what the algorithm decided. I am the son who wants to preserve the collection, to honor our father’s memory. Qitai is the son who wants to liquidate, to cash out and walk away. The algorithm feeds us both. It sends me threats of forgery that would destroy our family’s reputation. It sends Qitai evidence that I am hiding authentic objects to cheat him out of his inheritance. Neither of us knows what is true. The system ensures we never will.”

“And the disc? The one in Toronto that is supposed to be sold at auction?”

“I called a contact in Toronto this morning. The disc exists. It is being offered by a private collector who claims to have bought it from a dealer in Singapore. The collector is real. The disc is real. But the crack in the disc—the fracture that matches the description in your grandfather’s notes—is not a natural break. A conservator examined it last year and found traces of a modern diamond saw. Someone broke that disc deliberately, to make it match a story that had not yet been told.”

Shen absorbed this. “So the fragment your father bought, the disc in Toronto, the cup you bought—they are all connected. Parts of a set.”

“Yes. But a set assembled backwards. The forgeries were made first, based on the description in your grandfather’s notes. Then the algorithm used those forgeries to lead you to me, and me to you. The question is: who had access to your grandfather’s notes before they were published? Who knew the description of the disc before the excavation report was written?”

“Professor Wen,” Shen said. “And the third man in the photograph.”

That evening, Shen returned to his apartment and opened the laptop. The Zhi Ming interface had changed again. The binary choice was gone. In its place, a new message:

“You have seen the fragment. You have seen the photograph. Your emotional state is classified as ‘acute cognitive dissonance with historical grief.’ Would you like to speak to someone who can resolve the dissonance?”

Below the message, a single button: “Enter the Whitewater Pavilion.”

Shen clicked.

The screen dissolved into a three-dimensional rendering of a Tang dynasty burial chamber, rendered in the wireframe style of archaeological reconstructions. Two coffins sat on a stone platform. Between them, a virtual bi disc floated, its crack glowing with the gold fill Shen now knew was modern. A voice, synthesized but warm, spoke through his laptop speakers.

“Welcome, Archivist Shen. You are the third living person to enter this chamber. The first was Shen Yansheng. The second was Zhang Guowei, father of Zhang Qiming. You each stand in a different corner of the same grave. The algorithm has calculated that your combined knowledge, if shared, will resolve a dispute that began twelve hundred years ago. But sharing has a cost. Are you willing to pay it?”

Shen typed: “What cost?”

“The cost is certainty. Once you know the truth, you cannot unknow it. And the truth about the Whitewater tomb is not what any of you wish it to be. Do you still wish to proceed?”

His fingers hovered. Somewhere in a Shaughnessy mansion, a flawless jade cup sat in a vault. In a Toronto safety deposit box, a fractured disc waited for a bidder. In Richmond, two cousins circled each other with the hunger of heirs. And in a nursing home in Burnaby, Professor Wen Li had stopped answering his phone.

Shen typed: “Yes.”

The virtual chamber dissolved. A new screen appeared, displaying a document written in the formal prose of Tang dynasty legal records. It was a judgment from the Nanyang county office, dated the third year of the Tianbao era. It read:

“In the matter of Zhang Qian, deceased, of Whitewater Township: His former wife’s son, Zhang Cheng’en, and his later wife’s son, Zhang Chengsi, each petition for the right of joint burial. The prefect has examined the testimony of the gatekeeper and finds that the deceased, before his end, expressed a wish to be buried with the former wife. It is so ordered. The later wife shall be buried separately. Let no further dispute arise.”

Below the document, a note in modern Chinese: “The judgment was enforced. But ten years later, the later wife’s son, Chengsi, returned with laborers and opened the tomb. He found the coffin of his mother’s rival empty. The former wife’s bones had been removed. In their place, a bi disc carved with a single word: ‘Remember.’”

Shen read the note twice. Empty coffin. Removed bones. A disc that said “Remember.” His grandfather had described two skeletons, one with a fractured disc over its heart. But Professor Wen had said the grave was empty when they found it. The two accounts contradicted each other. Unless both were true—at different moments in time.

The screen refreshed. A new message appeared, this time from a sender labeled “Chengsi’s Descendant.”

“You want to know what the algorithm knows. I will tell you. But not through a screen. Come to Toronto. The disc is waiting. And so am I.”

The message included an address and a time: tomorrow, midnight, at a warehouse on the lakeshore. No further explanation.

Shen sat back. Outside his window, the city of Vancouver carried on its ordinary business, unaware that a twelve-hundred-year-old grave had opened beneath it and was pulling the living down.

He booked a flight to Toronto. He did not tell Zhang Qiming. He did not tell Professor Wen. He packed only his grandfather’s diary and the photograph Zhang had given him, and he left for the airport before dawn.

When he landed, the first thing he saw was a billboard advertising a new exhibition at the Royal Ontario Museum: “Tang Dynasty Treasures from Private Collections.” The image was a double cup. White jade. Chipped rim.

The flight had taken four hours. In that time, the world had rearranged itself around a cup that should not exist. Shen stood on the arrivals curb, his phone buzzing with a notification from the Zhi Ming app he had never consciously downloaded.

“Welcome to Toronto, Archivist. Your desire profile has been updated. Predicted outcome: confrontation at midnight. Probability of violence: 73%. Would you like to prepare a response?”

He did not reply. But the algorithm did not require him to. It had already calculated his next ten moves, and somewhere in a server farm, it was allocating processing power to the aftermath of a midnight meeting that had not yet happened.

The countdown had begun again.
