4. 乐谱残章

The courthouse annex on Hanezawa was a two-story building that had once been a colonial administrative office, back when the island was governed by men who wore crisp military uniforms and believed that paperwork could conquer anything. Its walls were still the same faded ochre, streaked with decades of typhoon scars. The brass plaque beside the door read "Hanezawa Legal Affairs Bureau – Branch Office," but the building was dark, its windows reflecting only the bruised sky.

Rin and Miyagi arrived as the first drops of the new storm began to fall. The cruiser's headlights swept across the empty parking lot, illuminating nothing but puddles and scattered debris. There was no sign of Takagi's rental car, no indication that anyone had been here since the typhoon.

"He said he was coming here," Miyagi said, leaning forward to peer through the rain-streaked windshield. "But the building looks abandoned."

Rin got out of the car without waiting. The wind had picked up again, gusting at forty knots, whipping her coat around her legs. She approached the annex's front door and found it slightly ajar, the lock mechanism scratched and dented as if someone had forced it open recently.

She drew her revolver and pushed the door open with her shoulder. The interior was dark, smelling of old paper and damp plaster. The emergency lighting had failed, and the only illumination came from the gray light filtering through the windows. She could hear the rain hammering against the roof, a sound like a thousand fingers drumming impatiently.

"Takagi Wataru," she called. "This is Detective Kuresaki. Are you in here?"

No response. But somewhere deeper in the building, she heard a sound. A soft, rhythmic tapping, like a branch scraping against glass. She moved down the corridor, Miyagi close behind with his flashlight. The tapping grew louder, more insistent.

They found him in a records room on the second floor. Takagi was sitting in a swivel chair, his back to the door, facing a wall of filing cabinets that had been pulled open and emptied. Papers were scattered everywhere. But what made Rin's breath catch was the thin trickle of blood running from beneath his chair, winding across the linoleum floor like a red serpent.

"Takagi."

She spun the chair around. His face was pale, his eyes half-closed, but he was alive. A gash on his forehead had bled profusely, the blood matting his carefully groomed hair. His suit was torn at the shoulder, and his hands were shaking.

"They took it," he whispered. "They took everything."

Miyagi was already calling for medical support on his radio. Rin knelt beside Takagi, pressing a handkerchief against the wound on his head. "Who did this? Who took what?"

"Two men. They were waiting when I arrived. They knew I had the files. The financial records from Prosecutor Shima's investigation. They had a crowbar. I didn't see their faces. They wore masks. Ski masks, like they were expecting the storm." He coughed, wincing. "They wanted the same thing Shima was looking for. The hidden accounts. The money trail."

"Did they say anything that might identify them?"

Takagi's eyes focused on her with sudden intensity. "One of them spoke Korean. The other spoke Japanese, but with a mainland accent. Not from the island. They knew exactly where to find me. They knew I had the files. Someone told them I was here."

Rin's mind raced. The only people who knew Takagi was at the courthouse annex were herself, Miyagi, and the staff at the Sea Breeze Inn. And whoever had been watching her from across the street, taking photographs and leaving warnings. The circle of surveillance was tightening.

"Did you see the files before they were taken? What was Shima investigating specifically?"

Takagi struggled to sit up. "Construction contracts. Government contracts for military infrastructure projects in the disputed territories. Hundreds of billions of won. Shima discovered that a network of shell companies was funneling money through Hanezawa to avoid taxes and oversight. The island's status as a remote territory made it perfect for laundering. He was closing in on the identity of the mastermind when he was killed."

"Did he have a suspect?"

"A name. He mentioned it once, during one of our encrypted calls. A codename. 'The Lighthouse Keeper.' He said the Lighthouse Keeper controlled everything on the island. The money, the smuggling routes, the politicians. But he never told me the real identity. He said it was too dangerous."

Outside, the storm was intensifying. The wind had become a constant roar, and the rain was falling so hard it sounded like gravel being poured onto the roof. Rin could feel the building shudder with each gust.

"We need to get you to the clinic," she said. "Miyagi, help me lift him."

They carried Takagi down the stairs and into the cruiser. The drive to the clinic took twenty minutes, the roads now treacherous with flooding. Dr. Murakami was waiting at the entrance, his elderly face creased with concern. He took one look at Takagi's head wound and led him into the examination room without a word.

Rin stood in the clinic's waiting area, staring at the blood on her hands. The handkerchief was soaked through. She washed her hands in the small bathroom sink, watching the water turn pink and then clear. In the mirror, her face looked gaunt, hollowed out by exhaustion and something else. Something that felt like dread.

Miyagi appeared in the doorway. "Detective. I just got off the radio with the mainland. The classified bunker plans you requested. The prefectural archives are sending them by encrypted fax. They should arrive within the hour."

"Good. I'll need them." She dried her hands and turned to face him. "I also need you to do something for me. Park Joon-suh, the old man at the inn. He told me that The Parting Song is a code. A map to something hidden in the tunnels. I need to understand how the code works. He's the only one who might know. I want you to take him to the substation and keep him safe. Someone is killing everyone connected to this case, and he's next on the list."

Miyagi's expression hardened. "You think the same people who attacked Takagi will go after Park?"

"I think anyone who knows about the song is a target. Lee Young-ja knew. Now she's dead. Shima found something, and he's dead. Takagi almost joined them. Park Joon-suh is the last living connection to the resistance that hid whatever is in those tunnels. If the killers find him before we do, we lose our only chance to decipher the map."

Miyagi nodded and left. Rin remained in the waiting area, watching the rain streak down the windows. After a few minutes, Dr. Murakami emerged from the examination room.

"He'll recover. The wound is superficial, though head wounds always bleed dramatically. He has a mild concussion and some bruised ribs. I've given him something for the pain. He's resting now, but you can speak with him briefly."

Takagi was propped up in a hospital bed, his head bandaged, his color returning. He looked smaller than he had in the villa, diminished by the fluorescent lights and the sterile white sheets. The arrogance that had defined his first appearance was gone, replaced by something more human. Fear, perhaps. Or the beginning of trust.

"Detective," he said, his voice weaker than before. "There's something I didn't tell you earlier. I should have, but I was afraid."

Rin pulled a chair beside his bed. "Tell me now."

"When Shima sent me the recording, the one that cut off before he finished, he also sent a second file. Encrypted. He said to only open it if something happened to him. I opened it this morning, before the attack. It was a ledger. Names. Dates. Amounts. But the most recent entry was different. It wasn't a financial transaction. It was a location. The old lighthouse on Cape Kiryuu. He wrote that the lighthouse was the key. The Lighthouse Keeper wasn't just a codename. There's a real lighthouse, and someone is operating it."

Rin's mind went immediately to the villa. Cape Kiryuu, where Shima had chosen to live during his investigation. The lighthouse was visible from the study window, a stone tower built during the colonial era, automated decades ago. Or so everyone believed.

"Did the ledger say who?"

"No. But it mentioned a schedule. Every Tuesday and Thursday night, a signal is sent from the lighthouse. Not a light signal. Something else. A radio frequency. Shima believed the Lighthouse Keeper was using the old naval communications array to transmit encrypted data to a network of ships offshore. Smuggling vessels. He was trying to intercept the next transmission when he was killed."

Outside, the wind shifted direction, and the clinic's walls groaned. Rin stood up, her coat heavy with the weight of her revolver. "I need to see that ledger."

"The men who attacked me took the original files, but I made a backup. It's in my room at the inn. Under the floorboard beneath the dresser. The combination to the safe is 1948."

The year 1948. The year of the uprising on Jeju Island, the mass killings that had driven so many Koreans into hiding, into resistance, into the tunnels beneath Hanezawa. Rin felt history pressing against the walls of the clinic, a presence that was not quite ghostly but not quite material either. A weight that the island had been carrying for seventy years, waiting for someone strong enough to lift it.

She left Takagi to rest and drove alone to the Sea Breeze Inn. The streets were empty again, the residents of Hanezawa having learned to read the sky and know when to hide. The inn's lobby was dark, but Yoshiko was still at the front desk, as if she never slept. Her prayer beads clicked softly in the silence.

"Room 204," Rin said. "I need to retrieve something."

Yoshiko handed her the key without a word. Her eyes were red-rimmed, and Rin realized she had been crying. For Lee Young-ja, perhaps. Or for the island itself, which seemed to be crumbling under the weight of its own secrets.

The room was neat, almost obsessively so. Takagi had made the bed with military precision, his toiletries arranged in a perfect line on the bathroom counter. Rin found the dresser and moved it aside. The floorboard beneath was loose, and inside the hollow space was a small fireproof safe. She dialed 1948 and the lock clicked open.

Inside were two items. A USB drive, presumably containing the backup ledger. And a photograph. An old photograph, printed on paper that had yellowed with age. It showed three men standing in front of a stone building she recognized as the old lighthouse on Cape Kiryuu. Two of the men were Korean, dressed in the rough clothing of laborers. The third was Japanese, wearing the uniform of a colonial military officer.

On the back of the photograph, in handwriting she recognized from the journal, were three names. Park Min-sik. Lee Dong-soo. Kuresaki Kenji.

Her father's name.

The world tilted. She gripped the dresser to steady herself, her vision swimming. Kuresaki Kenji. Her father. The man who had raised her, who had taught her to shoot, who had retired from the Metropolitan Police as a decorated superintendent and died three years ago of liver cancer. Her father, whose hands had never touched a weapon in anger, whose moral compass had always pointed true north.

Or so she had believed.

She stared at the photograph, at the face of the young officer standing beside two Korean resistance fighters in front of a lighthouse that was somehow the key to a vast conspiracy of money laundering and murder. Her father had been stationed on Hanezawa during the early years of his career. She knew that. He had mentioned it once, in passing, when she received her first posting. "It's a hard place," he had said. "Beautiful, but hard. It tests you in ways you don't expect."

He had never mentioned the lighthouse. He had never mentioned the resistance. He had never mentioned the two Korean men whose names were written on the back of this photograph, men whose descendants were now dying one by one.

Rin put the USB drive and the photograph in her coat pocket and replaced the floorboard. Her hands were steady, but her mind was not. The scar on her ribs pulsed with that familiar rhythm, the tempo of a half-remembered song that was no longer just a song.

She drove back to the substation through streets that were slowly turning into rivers. The fax machine was humming when she arrived, spitting out page after page of old blueprints. Miyagi had already brought Park Joon-suh from the inn, and the old man was sitting at her desk, his gnarled hands tracing the lines of the bunker plans as if reading braille.

"These plans are incomplete," Park said without looking up. "The military drew them to deceive. There are levels here that don't appear on any official map. Secret rooms. Escape tunnels. The resistance knew about them. That's how we survived."

Rin spread the photograph on the desk beside the blueprints. "Do you know who these men are?"

Park adjusted his glasses and peered at the photograph. His breath caught. "This was taken at the lighthouse. Before the massacre. The Japanese officer, I remember him. He was not like the others. He helped us. He warned us when the military police were coming. Without him, many more would have died."

"His name. Do you remember his name?"

Park squinted at the photograph, at the young officer's face. "Kuresaki. They called him Kuresaki. He was an intelligence officer, but his sympathies were with the resistance. He believed what the colonial government was doing was wrong. He fed us information for almost two years before he was transferred back to the mainland."

Rin sat down heavily in the chair across from him. "Kuresaki Kenji was my father."

The old man stared at her, his clouded eyes suddenly clear. "Your father. Then you have his blood. And perhaps his burden." He paused, his gaze dropping to the blueprints. "There is something you should know. Before he left the island, your father hid something in the tunnels. He told only a few people. Lee Dong-soo was one of them. Lee Young-ja was his daughter. That is why they killed her. They thought she knew where it was."

"Where what was?"

"The evidence. Your father was an intelligence officer. He had access to documents that proved the colonial government's involvement in atrocities. He also knew about the gold. He helped the resistance hide it. But he also kept a record. Names of collaborators. Names of officers who gave orders. Names that certain people in the current government would prefer to remain buried."

Park reached into his jacket and withdrew a folded piece of paper. It was old and brittle, stained with what might have been tea or blood. "Lee Young-ja gave this to me for safekeeping. She said if anything happened to her, I should give it to someone who would finish what her father started. I think you are that someone."

Rin unfolded the paper. On it was a musical staff, hand-drawn, with notes arranged in a pattern she now recognized. The Parting Song. But this version was different. Below each measure, Lee Young-ja had written a series of numbers and Korean characters. A cipher key. The code, finally cracked.

"The numbers correspond to the bunker grid coordinates," Park said. "The characters are compass directions. Lee Young-ja spent forty years decoding her father's work. The song leads to a chamber beneath the old lighthouse. That is where your father hid the evidence. And that is where the killers will go next."

Rin looked at the clock on the substation wall. It was almost midnight. The storm outside was howling, the wind shaking the building to its foundations. Somewhere out there, in the darkness between the lighthouse and the sea, two masked men were searching for the same chamber. And they had a head start.

She stood up and holstered her revolver. "Miyagi, you're with me. We're going to the lighthouse."

Park grabbed her wrist with surprising strength. "Be careful, Detective. There is a reason your father never came back for the evidence. Some doors, once opened, cannot be closed. And the lighthouse has been watching this island for a very long time."

Rin nodded and stepped out into the storm. The rain hit her like a wall, and the wind nearly knocked her off her feet. But she kept walking, toward the Cape, toward the lighthouse that had haunted her father's past and was now reaching into her own.

Behind her, in the substation, the fax machine continued to hum. And on the desk, the photograph of three men smiled up at the fluorescent lights, their faces frozen in a moment that had happened before the blood, before the gold, before the song became a map to things that should have remained buried.
