5. Signal Fires

The mirror shattered with a sound like a bell struck once and broken. Shards of silvered glass rained onto the marble hearth, and behind the ruined frame, the wireless transmitter continued its silent, patient tapping—a heartbeat of vacuum tubes and copper wire, sending its signal into the fog.

Fei stood frozen, the candlestick still raised in his hand, his chest heaving. The guards in the hallway shouted. Boots pounded on the parquet floor. They would be on him in seconds. But before they reached the drawing room doors, a new sound cut through the chaos: the window at the far end of the room sliding open, and a figure—lean, dishevelled, his coat torn and his eyes blazing—climbing over the sill.

L.K. Eng.

“You took your time,” Fei said, the words escaping him in a rush of something that was almost laughter.

“The sewers were occupied,” Eng replied. He crossed the room in three strides and knelt beside the hollow space behind the mirror. His fingers moved over the transmitter with the precision of a surgeon, tracing the wires, reading the frequency dials. “This is the relay. It links the villa to the *Silver Lily*. Every word spoken in this room is broadcast directly to the Abacus’s central processor. They are listening to us now.”

“Then let them listen,” Fei said. He reached into the hollow and pulled out a sheaf of papers—the documents Shen had prepared, the guarantee for his mother, the script of the kidnapping. He threw them into the cold fireplace. “I am done following their script.”

Eng looked at him, and something passed between them—an understanding forged in the shared knowledge of what it meant to be hunted by a machine. “Then we write our own. But we have maybe two minutes before those guards break down that door. The transmitter has a built-in microphone. If we speak clearly, our words will go not only to the *Silver Lily*, but to every receiver tuned to the Abacus’s frequency. Petrov has been broadcasting the signal across the city for the past hour, using an amplifier he rigged in the French Concession. Every newspaper office, every police station, every teahouse with a wireless set will hear what we say.”

“Petrov? The Russian?”

“He owed me a debt. And he hates the Abacus more than he loves vodka. Which is saying something.”

The guards were at the door now, their shoulders crashing against the oak. The hinges groaned. Eng turned to the transmitter and pressed the transmission key.

“This is L.K. Eng, former senior telegraphist of the Great Northern Telegraph Company, speaking from a villa on the Rue du Consulat. I am here with Fei Xinsheng, the man the Jade Abacus has framed for a kidnapping that has not yet occurred. The Abacus is not a crime prevention system. It is a weapon of censorship and control, operated by a consortium calling itself the Committee for Civic Harmony. Its chief analyst is a man named Shen Lianzhi. Its British liaison is Dr. Harold Vance. They have manufactured evidence, spread false rumours, and threatened the families of innocent men to create the crimes they claim to predict. Zhang Yuanji is being held in this villa, sedated but unharmed. He is a prisoner not of Fei Xinsheng, but of the machine.”

Eng paused, his eyes meeting Fei’s. Fei stepped forward and spoke into the transmitter, his voice steadier than he expected.

“My name is Fei Xinsheng. I was a compositor at the Commercial Press. I was dismissed because I refused to become an informant for the Abacus. The system assigned me a threat value and began to whisper my name into the ears of the city. It told my neighbours I was a radical. It told the police I was a bomber. It told me that if I did not commit the crime it had predicted, my mother would be killed. I am not innocent—I am complicit in my own destruction. But I am not the author of this story. The machine is the author. The men who built it are the authors. And they are listening now.”

The door burst open. The guards spilled into the room, their guns raised. Behind them came Dr. Vance, his face pale with fury, and behind him, moving with the slow, deliberate calm of a man who had already calculated the outcome, Shen Lianzhi.

“Turn off the transmitter,” Shen said. His voice was flat, but his jade worry balls were still in his left hand, clicking furiously. “You do not understand what you are doing. The Abacus is not a weapon. It is a shield. Without it, the city will tear itself apart. The warlords, the unions, the secret societies—they are chaos. The Abacus is order.”

“Order built on lies,” Eng said. “A prediction that creates its own fulfilment is not a prediction. It is a conspiracy.”

Shen’s eyes flickered—a micro-expression, quickly suppressed. “The algorithm has already calculated your next moves. Both of you. You will be arrested. The transmission will be dismissed as the ravings of a disgraced telegraphist and a criminal. The newspapers will not print your story. The police will not investigate. The machine is too deeply embedded. You cannot dismantle it with words.”

“You are wrong,” Fei said. “Words are the only thing that has ever dismantled a machine. Zhang Yuanji taught me that. An encyclopedia is a machine made of words. And it can be used to build—or to destroy.”

The guards advanced, their weapons trained on Eng and Fei. Eng raised his hands slowly. Fei did the same. They could not fight their way out, and they both knew it. But the transmitter was still active. The signal was still broadcasting. And somewhere in the city, a reporter was scrambling for a notepad. A police constable was frowning at his wireless set. A teahouse full of clerks and rickshaw pullers was falling silent, listening.

Shen approached the transmitter and, with a single, precise motion, ripped the wires from its base. The vacuum tubes dimmed. The heartbeat stopped. But the damage had already been done.

“Take them,” Shen said. “Separate cells. No communication. The resolution phase will proceed as planned.”

The guards dragged Eng and Fei out of the drawing room. As Fei was pulled past the staircase, he caught a glimpse of Zhang Yuanji standing at the top of the stairs, supported by the physician, his face pale but his eyes clear. The old scholar raised one hand in a gesture that was half blessing, half farewell.

Then Fei was shoved into the back of a motorcar, and the night swallowed him whole.

The trial took place three weeks later, in the austere courtroom of the Shanghai District Court. The gallery was packed with journalists, foreign dignitaries, and the simply curious. Zhang Yuanji, fully recovered, sat in the front row, his spectacles catching the light from the high windows. Eng was not present; he had been released after forty-eight hours of interrogation, the charges against him dropped under mysterious circumstances. But his testimony had been submitted in writing, a forty-page document that detailed every interception, every threat value, every whisper.

Fei stood in the dock, his borrowed suit replaced by a prison uniform. He pleaded not guilty to the charge of kidnapping, though the prosecution presented a mountain of evidence: the note from the Abacus, the testimony of the guards who had found him at the villa, the ransom message that had been delivered to the Press. The defence argued entrapment, citing Eng’s evidence. The prosecution countered that the Abacus was a legitimate crime prevention tool and that Fei’s actions—regardless of motivation—constituted the predicted crime.

The trial lasted four days. On the fifth day, the judge called for closing statements. Zhang Yuanji rose from his seat and asked to address the court. The judge, a British jurist with a reputation for impartiality, granted the request.

Zhang walked to the front of the courtroom and faced the judge, the jury, and the packed gallery. His voice was quiet, but it carried to every corner of the room.

“I am Zhang Yuanji,” he said. “I am the victim in this case. But I stand here today to say that the man in the dock is not my kidnapper. He is my rescuer. The true kidnappers are the men who built the Jade Abacus. They held me in that villa not for ransom, but for a narrative. They needed a crime to justify their system. They chose Fei Xinsheng because he was vulnerable, because he had refused to become their spy, because his mother lived in a village they could reach. They did not predict a crime. They manufactured one. And they would have succeeded, if not for the courage of two men: L.K. Eng, who found the truth, and Fei Xinsheng, who refused to become the villain they had written for him.”

He paused, and the silence in the courtroom was absolute.

“I plead with this court to see the difference between justice and the appearance of justice. The machine is the criminal. The men who built it are the criminals. Fei Xinsheng is their victim. I ask you to acquit him.”

The judge thanked Zhang for his statement and dismissed the court for deliberation. The jury returned in less than an hour. The verdict: guilty. The sentence: death by firing squad.

The courtroom erupted. Zhang Yuanji closed his eyes. Fei, in the dock, showed no surprise. He had known, from the moment he smashed the mirror, that the system would not forgive him. The machine’s purpose was not justice but validation. An acquittal would have invalidated the algorithm. A guilty verdict confirmed it.

And so, on a grey morning in November 1927, Fei Xinsheng was led into a courtyard behind the Shanghai Municipal Prison. A priest offered him a cigarette. He refused. A blindfold was placed over his eyes. He thought of his mother, who had been moved to a safe house by Chen’s men before the Committee could reach her. He thought of Zhang Yuanji, who had promised to continue the encyclopedia, with a new entry on the dangers of pre-judgment by machine. He thought of Eng, who had vanished into the city’s depths, carrying the evidence that could not be spoken in court.

And he thought of the whispers. The whispers that had killed him, that were even now drifting through the city’s wires, searching for their next target.

The rifles fired. Fei Xinsheng fell. The system was validated.

In the weeks that followed, the Committee for Civic Harmony issued a statement praising the Abacus for its successful prediction and resolution of the Zhang Yuanji kidnapping. The newspapers, with a few exceptions, printed the official account. The encyclopedia’s labour history volume was quietly cancelled. The city returned to its rhythms of commerce and jazz, of opium and silk, of rickshaws and telegraph wires humming with secrets.

But something had changed. In the teahouses and the printing shops, in the union halls and the university lecture rooms, people remembered the broadcast. They remembered the voice of L.K. Eng, describing a machine that manufactured guilt. They remembered the voice of Fei Xinsheng, admitting his complicity but denying his authorship. The whispers had been exposed, and once exposed, they could not be unheard.

Zhang Yuanji returned to the Commercial Press and, at great personal risk, authorized the printing of a pamphlet titled “The Jade Abacus: A Warning.” It detailed the mechanics of the system, the names of its known operatives, and the techniques it used to spread its whispers. The pamphlet was banned within a week, but not before five thousand copies had been distributed across the city. In the margins of the banned text, readers scribbled their own annotations, their own names, their own threat values.

L.K. Eng disappeared. Some said he had fled to Hong Kong. Others said he was living in the sewers, moving through the city’s underworld like a ghost. A few—the ones who knew him best—said he was still in Shanghai, listening to the wires, waiting for the next signal, the next whisper, the next victim. He had become, in his own way, a machine himself: a counter-Abacus, a human algorithm for justice.

And on the river, the *Silver Lily* continued to drift, its transmitter pulsing out its quiet, relentless heartbeat. The Abacus had not been destroyed. It had only been named. Its threat values continued to circulate. Its whispers continued to spread. Somewhere in the city, a factory foreman looked at a worker with suspicion. A landlord evicted a tenant on the strength of a rumour. A journalist killed a story before it could be written. The machine was still weaving its web, strand by invisible strand, victim by silent victim.

But now there was a counter-frequency. A signal in the static. A voice that said: *You are not what they say you are. The machine is wrong. The whispers are lies. And lies, once exposed, cannot survive the light.*

The fog rolled in from the Huangpu, thick and white, erasing the line between the real and the rumoured. In a basement in the French Concession, Petrov’s radio equipment glowed in the dark, its vacuum tubes humming with the city’s secrets. A new transmission was coming through. A new name. A new threat value. A new script being written by invisible hands.

And somewhere, in the static, a telegraph key began to tap.
