2. 药房之眼

The lullaby drifted through the fog like a thread of smoke—soft, wordless, a melody that rose and fell with the rhythm of a rocking cradle. Sakuma stood frozen at the shrine platform, his hand still pressed against the cold stone, and listened. The tune was unfamiliar, yet it carried a weight of memory, as if it had been sung a thousand times in this valley, to children who had long since grown or gone.

Then the fog shifted, and the sound stopped. A crow cawed from the pines, and the silence that followed was absolute. Sakuma pulled his hand back, flexing his fingers to restore circulation. He scanned the tree line but saw nothing—only the grey trunks and the white ground, merging into a single canvas of winter erasure.

He returned to the general store through the back alley, avoiding the well where Oba's body still lay. The villagers had already dispersed, their duty of spectacle fulfilled. He slipped into the storage room, retrieved his rucksack, and moved everything into the abandoned schoolhouse he had noticed on his first day. It was unlocked, dusty, and cold, but it had a working lock on the inside, and the windows faced the shrine. From the second-floor classroom, he could see the platform, the grove, and the path that led to Tanaka's clinic. He set up his sleeping bag in the corner, placed his notebook and camera on a desk, and began to piece together what he knew.

The timeline was thin but suggestive. Oba had said Tanaka arrived thirty-two years ago—1993, by his calculation. The boy's exile, according to Shiori and Oba, occurred in the winter of 1983. That left a gap of ten years. If the boy had survived the sulfur vents, he would have been severely burned in the lungs, possibly scarred on the skin. He would have needed medical treatment, rehabilitation, a new identity. A boy from a remote village, with no birth certificate to speak of, could easily become someone else—especially if he was smart, driven, and willing to bury his past.

Sakuma opened his notebook and wrote a list of questions: 1) How did Tanaka get his medical degree? 2) Why choose this village, of all places, for his practice? 3) What happened to the sister who screamed for three days? 4) Where are the remains of the original father, buried or disposed of? 5) Who else from the original elders is still alive?

He underlined the last question. Oba had been the last link to that generation—or so she had implied. If the elders were all dead, then the only living witness to the boy's fate was the boy himself, and possibly the sister, if she had survived. He needed to find Shiori again.

He found her at the communal well, two hours later, standing alone beside the rope and pulley. Oba's body had been removed—taken to the clinic, someone told him—and the well was covered with a wooden lid. Shiori wore the same wool coat and knitted scarf, but her eyes were red-rimmed, and her hands were shoved deep into her pockets. She did not look at him when he approached, but she spoke in a low, rapid voice.

"Oba was my grandmother's cousin. She knew things. She told you, didn't she? That's why she's dead."

"I didn't tell anyone what she said."

"It doesn't matter. They know. They always know." Shiori turned to face him, and he saw that the scar above her eyebrow was more prominent today, pink against her pale skin. "My grandmother is bedridden. She can't speak anymore. But before she lost her voice, she wrote something down. She gave it to me and told me to keep it hidden." She pulled a folded piece of paper from her coat and pressed it into his hand. "Read it tonight. Not now. They watch."

She walked away before he could thank her, her boots crunching on the frozen path. Sakuma folded the paper without looking at it and slipped it into his inner pocket, next to his notebook. He spent the rest of the afternoon making a show of packing his gear, as if preparing to leave. He even walked to the bus shelter and stood there for ten minutes, checking an imaginary timetable. He wanted the village to believe he was frightened, that Oba's death had broken his resolve. Let them think that.

When dusk fell, he returned to the schoolhouse, barred the door, and lit a small candle. In its flickering light, he unfolded Shiori's paper. The handwriting was shaky, the strokes of an old woman who had once been educated but had long since stopped practicing. It read:

"He was not the only one. The sister ran away two years later, but she left a bundle at the shrine steps—a lock of hair and a child's kimono. The elders burned them. They said it was a curse. But I saved a piece of the kimono, buried under the persimmon tree behind my house. It has a name sewn into the collar. His name. He was always called Boy, but his real name was Tanaka—Tanaka Haruki. The doctor took that name when he arrived, but he did not know the sister had already left her mark. She named her son Tanaka, and she sent him back here to find the truth. He found it. And he never left."

Sakuma read the passage three times. His heart pounded. Tanaka Haruki—that was the boy. And the sister, who had fled, had named her own son after her lost brother. That son, now an adult, had come back to the village, perhaps to uncover what had happened, perhaps to avenge. But instead of finding justice, he had found something else—a role, a purpose, a transformation. He had become the keeper of the very system that had condemned his uncle.

Or had he? The note was ambiguous. "He found it. And he never left." That could mean he chose to stay and perpetuate the village's rule. Or it could mean he was trapped, bound by guilt and duty, unable to escape the legacy of his mother's grief.

Sakuma folded the paper and tucked it securely into his boot, under the insole. Then he extinguished the candle, waited an hour for his eyes to adjust, and slipped out of the schoolhouse through a rear window that opened onto a drainage ditch. He moved along the ditch, keeping to the shadows, until he reached the back of the clinic.

The clinic was dark, but a faint glow came from the side window—the examination room, where Tanaka had been writing in his ledger. Sakuma crouched below the sill and listened. He heard the scratch of a pen, the rustle of paper, and then a low voice, speaking to someone else.

"You shouldn't have come tonight. It's too soon."

A second voice, higher, nervous: "She told him. Oba told him everything. He knows about the boy, about the stone, about the fog road."

"I know. That's why I gave him the map. He'll go to the shafts, he'll find the entrance, and then the mountain will do the rest. We don't need to touch him. The sulfur will do it for us."

"But the other one—the blue parka man—we gave him the same map, and he almost made it out. He wrote that letter, and we never found where he hid it."

"He wrote nothing. He died with his mouth open, and his words froze before they could leave the valley. That's how it works. That's how it always works."

The first voice was unmistakably Tanaka's. The second voice was younger—Sakuma recognized it as the man who had been repairing the fishing net on the first day, the one who had held his gaze for three seconds. He filed that association and strained to hear more. But the conversation shifted to mundane matters—the shortage of blood pressure medication, the condition of the roof, the price of kerosene—as if the previous exchange had never happened.

Sakuma crept away, his mind reeling. The map Tanaka had given him was not a guide to safety—it was a lure, designed to steer him toward the sulfur vents, where an "accidental" exposure would kill him slowly and leave no evidence of foul play. And Miki, the missing investigator, had been given the same treatment. But Miki had apparently written something—a letter, perhaps a final report—and Tanaka had not found it. That letter could still exist, hidden somewhere in the village.

He returned to the schoolhouse and spent the rest of the night reviewing his notes. The key, he realized, was the persimmon tree behind Shiori's grandmother's house—the one where the old woman had buried the piece of kimono. That fragment of cloth might hold more than a name; it might hold fibers, dust, even a trace of the sister's final plea. And if it was still there, decades later, it could serve as physical evidence of the village's original crime—the exile of a twelve-year-old boy to a lethal fog.

Dawn came cold and grey. Sakuma went to the well, filled his canteen, and made a point of walking openly toward the main road, as if he were finally leaving. He carried his rucksack, his camera, and a visible map. He walked past the last house, past the bus shelter, and around the bend where the road disappeared into the forest. There, he ducked behind a thicket, waited ten minutes, and then circled back through the woods, using the drainage ditch as a covered route.

He reached Shiori's grandmother's house by mid-morning. It was a small, sagging structure at the southern edge, nearly swallowed by overgrown bamboo. The persimmon tree stood bare in the front yard, its branches like black veins against the sky. Sakuma found a rusty trowel in a shed and began digging at the base of the trunk, just as the note had described.

He dug through frozen topsoil, then softer earth, until his trowel struck something solid. He scraped away the dirt and uncovered a small tin box, rusted but intact. He pried open the lid with a knife, and inside, wrapped in oilcloth, was a scrap of faded silk—pale pink, with a small embroidered monogram. He unfolded it carefully and read the stitched characters: "Tanaka Haruki." Below the name, a single line of thread, red, had been sewn in a jagged pattern—as if the sewer's hand had trembled with grief.

He rewrapped the cloth and placed it in his inner pocket, alongside Shiori's note. He then refilled the hole, scattered leaves over it, and slipped back into the bamboo grove. As he was about to emerge, he heard footsteps on the path—light, deliberate, the gait of someone who knew exactly where they were going.

He pressed himself against a bamboo stalk and watched. Shiori walked past, her scarf pulled high, her hands empty. She did not glance at the persimmon tree. She did not look for him. She walked to the shrine, knelt before the rope, and placed a small offering—a rice ball, wrapped in a clean white cloth—on the steps. Then she bowed her head and remained still for a long moment.

Sakuma waited until she left, then approached the shrine. The rice ball was still warm. He picked it up, intending to examine it, but something else caught his eye—a fresh scratch on the wooden post beside the rope. It was a single line, vertical, as if made with a nail or a knife. And beside it, a smaller mark, a cross.

He traced the cross with his finger. It was not a Christian cross; it was the symbol for "burial" in the old mountain dialect, used on grave markers for those who had no formal plot. The vertical line represented the body, the horizontal line the boundary between life and death. Together, they formed a warning: this place was a tomb.

Sakuma stepped back and looked at the shrine with new eyes. It was not a place of worship—it was a monument to the buried, a marker for every soul the village had erased. And the rope that hung across the entrance, the faded paper streamers—they were not sacred decorations. They were the same ropes that had bound the boy's ankles, the same bindings that had held him to the stone.

He took a photograph of the scratch and the cross, then replaced the rice ball and retreated. On his way back to the schoolhouse, he passed the clinic. The door was open, and Tanaka stood on the porch, smoking a thin cigarette. He looked at Sakuma with an expression of mild surprise.

"Leaving, were you? I thought I saw you head toward the main road this morning."

Sakuma smiled. "I changed my mind. The snow on the pass is too deep. I'll wait another day or two."

Tanaka nodded, taking a long drag. "Wise. The pass can be treacherous in this season. You're welcome to stay at the clinic if you need a warmer bed. The schoolhouse must be freezing."

Sakuma's smile held. "I appreciate the offer. But I like the quiet. It helps me think."

Tanaka's eyes narrowed for just a moment—a flicker of something that was not warmth, not hostility, but calculation. Then he smiled again, nodded, and retreated inside. The door closed with a soft click, and Sakuma heard the lock turn.

He walked back to the schoolhouse and sat on the dusty floor, his back against the wall. He placed the silk fragment beside him, the note, and his notebook. He had uncovered the boy's real name, the sister's act of defiance, and the village's system of erasure. He had confirmed that Tanaka was indeed the boy's nephew—or, more precisely, the sister's son, sent back to investigate, who had instead become part of the machine. He had learned that Miki had written a letter that was never found. And he had seen the shrine's true purpose: a registry of the dead who were never allowed to be mourned.

But one question remained, burning in his mind like a sulfur flame. If Tanaka was the nephew, then where was the boy—the original Tanaka Haruki? Had he died in the fog, as everyone believed? Or had he survived, and was he still somewhere in this valley, older now, perhaps even more dangerous than his namesake?

He looked out the window at the ridge, where the fog had begun to rise again, grey and thick and silent. And he remembered the lullaby he had heard the previous night—that wordless melody, rising and falling like a cradle. It had not come from the village. It had come from the mountain.

He wrote one line in his notebook: "The boy is not dead. He is singing."

Then he closed the book, extinguished the candle, and waited for the dark to deepen, because he knew that tonight, he would have to walk into that fog and find the voice that had been calling him since the moment he arrived.
