5. The Second Old Man

The sealed envelope sat on Mahiru's kitchen table for three days before she opened it.

She was not procrastinating. She was preparing. The chest from Akijima contained hundreds of pages of material: census forms filled out in Tetsuya Shimazaki's careful hand, notebooks recording his daily observations, letters to his wife that grew increasingly anxious as the summer of 1965 progressed. Mahiru had spent the days since her return cataloging everything, cross-referencing names and dates with Kibe's encoded diary, building a timeline that stretched from June to July of that year, from the arrival of the census team to the night of the fire.

The sealed envelope was the last piece. She had saved it deliberately, the way she saved the best bite of a meal, the way she read the final chapter of a novel slowly, prolonging the moment before the ending.

On the third evening, with the city lights of Meikyo glittering beyond her window and the sound of rain pattering against the glass, she finally broke the wax seal.

Inside were three sheets of paper, folded together. The first was a letter from Shimazaki to his wife, dated July 1, 1965, the day before he died.

"My dearest Yuki," it began. "If you are reading this, it means I did not make it home. Something is wrong in this village. The population registers have been falsified for years, and the headman, Goro Adachi, has been stealing government money meant for families that do not exist. I have confronted him, and he has threatened me. He says I do not understand how things work in the mountains, that I should go back to the city and forget what I have seen. I told him I cannot do that."

Mahiru read on, her heart beating hard. Shimazaki had not merely suspected the fraud. He had documented it meticulously, collecting the names of phantom families, calculating the amount of money stolen, tracing the scheme back to its origins. And he had discovered something else, something that had clearly frightened him more than the fraud itself.

"There is a young man here," the letter continued. "He calls himself Jiro, though that cannot be his true name. He works for Adachi, but he is not merely an errand boy. He is the one who enforces the headman's will. The villagers speak of him in whispers. They say he has done terrible things, things that cannot be spoken of openly. I have seen him watching me. His eyes are like a hawk's, patient and unblinking. I believe he is capable of anything."

The second sheet was a list of names, the true residents of Hinagata, cross-referenced with the inflated numbers that had been reported to the Ministry. The discrepancy was stark. Shimazaki had counted 3,047 souls. The official report would claim 4,821. A difference of nearly two thousand, a lie large enough to distort electoral maps for sixty years.

The third sheet was a statement, written in formal language, signed and dated. It was addressed to the Ministry of Internal Affairs and the prefectural police. In it, Shimazaki detailed the fraud in full, naming Adachi and his accomplices, describing the threats he had received, and requesting immediate intervention. It was the letter he had intended to send the day he died, the letter that had never been mailed.

At the bottom of the third sheet, in a different hand, were three lines of text. Mahiru recognized the trembling script immediately. It was Kibe's handwriting, added years later, a postscript to a dead man's testament.

"I, Osamu Kibe, was present in Hinagata that summer. I saw what Jiro did. I have kept silent for too long. If this letter is found after my death, let it be known that Jiro is the man who now calls himself Takataro Sakuraba. May the gods forgive me."

Mahiru sat back in her chair. The rain had intensified, drumming against the window like impatient fingers. She had the evidence now. She had a murdered man's final letter, a witness's confession, and the original census data that proved the fraud. She could write the story tomorrow. She could publish it and watch the reputation of Takataro Sakuraba crumble like a sand castle in a storm.

But she also had a problem. Kibe was dead. Shimazaki was dead. The letter was compelling, but it was not proof of murder. A clever defense attorney would argue that Kibe was an old man with a grudge, that his confession was the product of guilt and senility, that the fire had indeed been an accident and Sakuraba had simply been a young man in the wrong place at the wrong time. The story needed more. It needed a living witness, someone who could testify to what had happened that summer and survive the cross-examination.

The monk. The fisherman. The two remaining young men from the photograph.

Mahiru reached for Kibe's notebook and flipped to the pages where he described his fellow witnesses. One had become a monk in the north, in a temple in the mountains of Hokkaido. Kibe had given him the pseudonym "Mizunashi," the waterless one, a reference to a peak on the horizon of Hinagata. The other had become a fisherman in the southern islands and was called "Isaribi," the fishing fire, after another mountain.

She needed to find them. But the north and the south were far apart, and she could not be in two places at once. If Sakuraba was already moving to eliminate the remaining witnesses, she might already be too late.

Her phone buzzed. A message from Emoto, brief and urgent: "Call me. Something has happened."

She dialed his number. He answered on the first ring.

"They know about the chest," Emoto said, his voice tight. "I do not know how, but they know. Someone came to my apartment this afternoon while I was out. The lock was broken. My papers were searched. Nothing was taken, but everything was disturbed."

"Are you safe?"

"For now. I am staying with my son in the western suburbs. But you should be careful. If they know I have the notebook, they may also know you have Shimazaki's papers."

"How could they know?"

"Kibe," Emoto said. "He must have told someone before he died. Or perhaps Sakuraba's people have been watching the tea house, or the ferry terminal, or the train station. I warned you, Miss Yuzuki. Sakuraba has eyes everywhere."

Mahiru looked at the papers spread across her table, the evidence of a sixty-year-old crime laid out like a surgeon's instruments. She thought about the old woman in the tea house, her warning about the shadows that followed Emoto. She thought about Kazue on the island, waiting for someone to finish her father's work.

"There are two other witnesses," she said. "A monk in Hokkaido and a fisherman in the south. I'm going to find them."

"Then go quickly. And tell no one where you are going."

The line went quiet, and Mahiru was alone again with the rain and the papers and the weight of what she had to do.

She booked a flight to Hokkaido for the next morning. The monk, according to Kibe's notes, could be found at a temple called Getsuonji, hidden in the mountains above the city of Hakuseki. It was a remote place, difficult to reach, the kind of place where a man might go to forget the world and be forgotten by it.

The flight was uneventful, a blur of clouds and recycled air and the muted anxiety of knowing that every hour she spent traveling was an hour Sakuraba could use to move against her. From the airport in Hakuseki, she took a bus into the mountains, then a taxi, then walked the final two kilometers up a narrow road lined with cedars so tall they blocked the sky.

Getsuonji was a modest temple, its wooden buildings darkened by decades of snow and rain. A stone garden occupied the central courtyard, raked into perfect concentric circles that seemed to ripple outward from a single point, like the surface of a pond disturbed by a stone. The air was cold and sharp, scented with pine and incense.

A young monk was sweeping the path. He looked up when Mahiru approached, his expression curious but not unwelcoming.

"I'm looking for a monk who came here many years ago," Mahiru said. "I don't know his religious name. But his given name, before he took his vows, was Riku."

The young monk's broom stopped moving. "Riku-sensei is in meditation," he said. "He does not receive visitors."

"I've come a long way to see him. It's urgent."

"I am sorry. He has given strict instructions. No visitors, under any circumstances."

Mahiru felt her heart sink. "Did he say why?"

The young monk hesitated, glancing toward the main hall as though expecting someone to appear. "He has been anxious lately," he said quietly. "He received a letter a few days ago, and since then, he has spoken to no one. He spends all his time in the meditation hall. He says he is preparing for a journey."

"A journey? Where?"

"I do not know. He would not say." The young monk leaned closer, lowering his voice further. "There is something else. Another visitor came yesterday, an older man from the capital. He spent an hour with Riku-sensei in the garden. After he left, Riku-sensei was different. Quieter. Afraid, I think, though he tried to hide it."

Mahiru's blood went cold. "An older man? What did he look like?"

"Distinguished. Very well-dressed. He had the bearing of someone important. He did not give his name, but he said he was an old friend of Riku-sensei from the village where they grew up."

Sakuraba. It had to be Sakuraba. He had reached the monk first.

"I need to see Riku-sensei," Mahiru said, her voice urgent. "Right now. Please."

The young monk looked torn. But something in her expression must have convinced him, because he set down his broom and gestured for her to follow.

The meditation hall was a separate building at the edge of the temple grounds, a small wooden structure surrounded by a ring of stones. The door was closed. The young monk knocked softly, then called out, "Riku-sensei, there is a visitor from Meikyo who wishes to speak with you."

No answer.

He knocked again, louder. Still nothing.

A chill ran down Mahiru's spine, a premonition she could not explain but could not ignore. She tried the door. It was not locked.

Inside, the meditation hall was dim and still. Cushions were arranged in neat rows on the tatami floor, each one empty. At the far end of the room, beneath a scroll bearing a single calligraphic character—"emptiness"—a figure sat in the lotus position, his back straight, his head bowed slightly forward.

"Riku-sensei?" the young monk called softly.

The figure did not move.

Mahiru approached slowly, her footsteps muffled by the tatami. As she drew closer, she saw that the monk was very old, his head shaved, his face lined with decades of contemplation. His eyes were closed, and his hands rested in his lap, palms upward, as though waiting to receive something.

And his face was the color of wax.

"He's dead," Mahiru whispered.

The young monk rushed forward, kneeling beside the old man, pressing his fingers to his wrist, his neck, searching for a pulse that was not there. "No, no, no," he murmured, his voice breaking. "He was fine this morning. He was fine. He sat down to meditate, and he told me not to disturb him, and I thought—"

"Call the police," Mahiru said. "And an ambulance. But do not touch anything else."

The young monk stumbled out of the hall, his cries echoing across the stone garden. Mahiru stood alone with the dead man, the silence pressing in around her like water.

She looked at Riku's face, peaceful but somehow wrong, as though the peace had been imposed from outside rather than arising from within. She looked at his hands, resting in his lap, and noticed a faint discoloration on his fingertips, a bluish tinge that seemed out of place on a man who had simply fallen asleep and never woken up.

On the cushion beside him was a small bowl, half-filled with what looked like green tea. Mahiru leaned closer, sniffing the liquid. There was no odor beyond the normal scent of tea. But something in her gut told her that the tea had been the vehicle, the same way the walk in the park had been the vehicle for Kibe's death. Quiet. Gentle. A death that looked like nothing at all.

She stepped back and scanned the room. In the corner, near the scroll, was a small cabinet where incense and tea implements were stored. On its surface, faint in the dim light, was a single fingerprint in what looked like dust, a print that was too large to belong to the young monk.

Sakuraba. He had been here, in this room, sitting across from the man he had known as a boy. He had drunk tea with him, spoken of old times, and then watched him die. And then he had simply walked out, a distinguished old man on a pilgrimage, leaving nothing behind but a body and a question.

The police arrived an hour later, followed by a coroner from Hakuseki. Mahiru gave a statement, explaining that she had come to interview the deceased for a story about rural depopulation. It was a thin lie, but it was enough. The police were not suspicious. They saw an old monk who had died during meditation, a natural end to a long life. They did not see what Mahiru saw.

By the time she left Getsuonji, it was evening, and the mountains were fading into silhouette against a sky the color of old copper. She walked back down the narrow road, her mind churning through the implications.

Three of the five young men were now dead. Shimazaki, killed in the fire. Kibe, dead in the park. Riku, dead in the meditation hall. The fisherman was the only witness left. And Sakuraba had proven, twice over, that he would not hesitate to kill to protect his secrets.

Mahiru pulled out her phone and booked the earliest flight she could find to the southern islands. She did not know exactly where the fisherman lived, but Kibe's notebook had given her enough clues to narrow the search. His pseudonym was Isaribi, the fishing fire. And in the back of the notebook, Kibe had drawn a small map of an island with a distinctive shape, a crescent of green around a deep bay.

She recognized that shape. It was Akijima. The same island where Kazue Wada lived. The fisherman and the census official's daughter had been neighbors for sixty years, neither knowing the full truth, both carrying pieces of the same shattered story.

She called Kazue from the airport, her voice urgent. "I'm coming back to Akijima. There's someone else on the island I need to find. A fisherman who was there the night of the fire."

"An old fisherman?" Kazue said. "There are many old fishermen on this island."

"His name, his given name, might be Taro. Do you know him?"

There was a long pause. Then Kazue spoke, her voice strange. "I know a man called Taro. He lives in a hut on the far side of the island, near the oyster beds. He is a strange man, very private. He does not speak to anyone. But sometimes, when I pass his hut on the way to the shrine, I hear him talking to himself. He says the same words, over and over."

"What words?"

"He says, 'I am sorry, Shimazaki-san. I am sorry I did not stop them.'"

Mahiru gripped the phone tighter. "Listen to me, Kazue. A man came to visit the monk in Hokkaido. An older man, distinguished, from the capital. The monk died the same day. I believe the same man will come for Taro. I need to reach him first."

"Then hurry," Kazue said. "The morning ferry leaves at six. I will meet you at the harbor."

The flight to Nishigawa was delayed by weather, and by the time Mahiru reached the port, the last ferry of the day had already departed. She spent the night in a cheap hotel near the harbor, lying awake on a mattress that smelled of mildew, staring at the ceiling and thinking about the dead monk and the tea he had drunk and the distinguished old man who had sat across from him and smiled.

In the morning, the ferry was nearly empty, a handful of islanders and a delivery of supplies. Mahiru stood at the rail and watched Akijima materialize from the mist, the green hump of the island rising from the sea like a promise or a warning.

Kazue was waiting at the harbor, her grey hair tied back, her face drawn with worry. "There has been a visitor," she said without preamble. "An older man arrived on a private boat yesterday evening. He went directly to Taro's hut and spent the night there. No one has seen him leave."

Mahiru felt her heart drop. "We're too late."

"Maybe not. Taro's boat is still at the dock. If the visitor killed him, he would have left by now. He is still here, on the island."

"Then take me there. Now."

They walked quickly through the narrow streets, past the closed shops and the shuttered windows, past the shrine and the citrus groves, following a path that led to the far side of the island where the land dropped sharply into the sea. The oyster beds stretched out below, dark shapes beneath the shallow water, and a single wooden hut stood on the cliff's edge, smoke rising from its chimney.

As they approached, the door of the hut opened and a figure emerged. It was not an old fisherman. It was a man in a dark overcoat, tall and straight-backed despite his age, his silver hair combed back from a high forehead, his features sharp and aristocratic. He moved with the grace of someone who had never made an accidental gesture in his life.

Takataro Sakuraba.

He saw Mahiru and Kazue approaching and stopped. His expression did not change. He did not look surprised, or angry, or afraid. He looked, Mahiru thought, like a chess player acknowledging a move he had anticipated several turns ago.

"Miss Yuzuki," he said, his voice smooth and warm, the voice of a man accustomed to being heard. "I was wondering when you would arrive."

"Where is Taro?" Mahiru demanded.

Sakuraba gestured toward the hut. "Inside. He is resting. We had a long night, talking about old times." He paused, his dark eyes studying her face with an intensity that made her skin crawl. "I understand you have been looking into the history of Hinagata. An admirable project. History is important. But some histories are more complicated than they appear."

"Complicated," Mahiru said. "Is that what you call murder?"

Sakuraba smiled, a thin expression that did not reach his eyes. "I call it survival. The village was dying. The young men in it were dying, slowly, of poverty and hopelessness. What happened that summer gave four of us a chance to live. Shimazaki was unfortunate, but his death was an accident. The fire was not meant to kill him. It was meant to destroy the census documents and give us time to negotiate with the headman. Shimazaki went back into the building to save his papers. That was his choice."

"You expect me to believe that?"

"I expect nothing. I am telling you because it does not matter what you believe. The only witness to contradict my account is an old fisherman who has spent sixty years talking to himself. He is not a credible witness. And the papers you collected from Miss Wada here—yes, I know about the papers—prove fraud, but not murder. The fire was ruled accidental. There is no forensic evidence to overturn that ruling. There is only the testimony of dead men and a journalist who has built her career on chasing shadows."

Kazue stepped forward, her voice shaking with anger. "My father was not a shadow. He was a good man, and you killed him."

Sakuraba's expression flickered, the first crack in his composure. "Your father was a good man," he said quietly. "I have thought about him every day for sixty years. He was the only one who refused to be corrupted. I admired him, even as I destroyed him. But I cannot bring him back. All I can do is protect the life I built from the ashes of that summer. And I will protect it, Miss Yuzuki. From you, from Professor Emoto, from anyone who threatens it."

"Is that a threat?"

"It is a promise." He stepped closer, his voice dropping to a murmur. "You have one choice. You can publish your story, and I will deny it, and my lawyers will bury you in litigation until your newspaper abandons you. Or you can walk away, and I will make sure the election suit receives a fair hearing. The vote disparity will be corrected. The maps will be redrawn. Justice will be done, the kind of justice that helps the living rather than avenging the dead."

"You are asking me to trade the truth for a political outcome."

"I am asking you to be practical. The dead do not vote. They do not need justice. The living do."

Mahiru looked at him, this man who had killed at least three people and built a reputation as the conscience of the judiciary, this man who could speak of practicality and justice in the same breath without a trace of irony.

"Taro," she said. "Is he still alive?"

Sakuraba hesitated. "He is sleeping. He will wake soon. We reached an understanding, he and I. He will not speak of the past. Neither will I. The silence that has held for sixty years will hold for a little longer."

"And if he changes his mind? The way Kibe changed his mind? The way Riku might have changed his mind?"

Sakuraba's eyes hardened. "Then I will do what I have always done. I will survive."

He turned and began walking toward the path that led to the harbor. At the edge of the cliff, he paused and looked back.

"The ferry leaves at noon," he said. "I suggest you be on it, Miss Yuzuki. There is nothing more for you here."

He disappeared over the ridge, and the sound of his footsteps faded into the wind.

Mahiru and Kazue rushed into the hut. The fisherman Taro was lying on a futon in the corner, his face pale but his chest rising and falling with slow, steady breaths. On the floor beside him was an empty cup and a small ceramic teapot, still warm to the touch. Kazue knelt beside the old man and pressed her hand to his forehead.

"He is alive," she said. "But he has been drugged. The same way the monk must have been drugged."

"But he didn't kill him," Mahiru said. "Why?"

Kazue looked at the empty cup. "Because he did not need to. Taro has been talking to himself for years. No one believes a word he says. He is not a threat. But the monk was different. The monk was respected. The monk could have been believed."

Mahiru sat down heavily on the wooden floor. The hut smelled of salt and old fish, and the wind whistled through the gaps in the walls. She had come to find a witness, and she had found one. But Sakuraba was right. A fisherman who talked to himself was not a credible witness. Without the monk, without Kibe, her case was thinner than she had hoped.

But she still had the papers. She still had Shimazaki's letter. And she had something Sakuraba did not know about: the sealed envelope, with Kibe's postscript naming Jiro as Takataro Sakuraba. It was not proof of murder, but it was proof of identity. It connected the orphan from Hinagata to the retired justice in Meikyo. And that connection, if she could find enough corroboration, might be enough to crack the edifice of lies that Sakuraba had spent sixty years constructing.

She looked at Taro, still unconscious on his futon. When he woke, she would ask him everything. She would record his testimony, document his story, and add it to the growing archive of evidence.

And then she would return to Meikyo and write the story that would bring Takataro Sakuraba to account. Not for the dead, perhaps. But for the living, and for the truth, and for the daughter of a murdered census official who had waited sixty years for someone to finish her father's work.

Outside, the wind was rising, and the sea was turning grey.
