1. The Drowned Witness

The call came at 3:17 a.m., dragging Qin Ming from a shallow, restless sleep into the thin, freezing drizzle of an autumn night.

By the time the forensic van pulled up to the banks of the Jiangcheng River, the scene had already been cordoned off with yellow tape that flapped wetly in the wind. The patrol officers stood in a loose cluster near the water’s edge, their flashlight beams slicing through the mist and bouncing off the black surface of the river. One of them, a young uniform named Liu, was visibly pale, his hand pressed against his stomach as if he were fighting the urge to vomit.

“Dr. Qin.” Captain Zhao, a stocky man with a weathered face, strode over and handed Qin Ming a pair of nitrile gloves. “Female, estimated late teens or early twenties. A sanitation worker spotted her floating face-down near the drainage outlet. We pulled her out twenty minutes ago. No ID, no personal effects. Bruising on the wrists and ankles suggests restraint.”

Qin Ming nodded, pulling the gloves on with practiced efficiency. He was a man of few words, his face lean and angular, his eyes carrying the quiet, unsettling stillness of someone who had spent too many years staring into the abyss. He had learned long ago that the dead spoke a language all their own, and his job was to translate it.

The victim lay on a white polyethylene sheet spread across the gravel bank, the reeds around her bent and flattened by the wind. She was small, her frame frail to the point of emaciation, her skin a waxy, mottled grey under the portable crime-scene lights. Her hair, which might once have been a glossy black, was now a tangled, matted mess, snarled with bits of river weed and trash. She wore a thin, cheap floral dress, the fabric faded and torn at the shoulder seam.

Qin Ming knelt beside her, his knee pressing into the cold, damp gravel. He began his external examination, his eyes moving slowly, methodically, from the crown of her head to the soles of her bare, abraded feet.

“Petechial hemorrhages in the conjunctivae,” he murmured, gently lifting an eyelid. “But no signs of prolonged submersion. The skin maceration on the hands and feet is mild. She hasn’t been in the water long. Twelve hours at most.”

He turned her head to the side, his fingers probing the scalp beneath the matted hair. “No obvious contusions or lacerations. The hyoid bone feels intact, no crepitus. Strangulation is unlikely as the primary cause.”

He shifted his attention to her torso, and his gaze sharpened. He unbuttoned the front of the dress carefully, folding it open to reveal her abdomen. There, just below the right rib cage, was a perfectly straight, six-centimeter surgical incision, closed with a neat row of sutures. The wound was fresh, the skin around it still showing faint traces of antiseptic staining, not yet fully healed. There was no redness or purulent discharge, which suggested the procedure had been done in a controlled, sterile environment—but not, Qin Ming suspected, a legally sanctioned one.

“Zhao,” he said quietly, his voice flat. “Take a look at this.”

The captain crouched down, his flashlight trained on the incision. He let out a low whistle. “That’s a surgical cut. Recent. Kidney?”

“I’ll confirm in the autopsy, but the location is consistent with a right nephrectomy.” Qin Ming straightened up and pulled a small evidence bag from his kit. He lifted the victim’s hands, one at a time, examining the fingernails. Under the third fingernail of her left hand, he found a tiny, dark speck. He scraped it out with a disposable tool and sealed it in the bag. “Trace evidence. Might be nothing. Might be something.”

It was as he was examining her right hand that he noticed the oddity. The victim’s middle finger was clenched into a fist, the other fingers loose and relaxed. Rigor mortis had set in unevenly, but this was different; the muscle contraction was too isolated, too deliberate. Qin Ming carefully pried the stiffened fingers apart.

Wedged deep in the crease of her palm, pressed so tightly against the skin that it had left a deep indentation, was a micro SD card. It was no larger than a fingernail, its black plastic casing smeared with a thin film of river silt.

Qin Ming held it up to the light, his expression unreadable. “She swallowed something. Probably a balloon or a condom. When the stomach acid broke it down, the card moved through the digestive tract. She must have retrieved it at some point and held onto it before she died.” He placed the card into a sterile evidence container, his mind already racing. “Whatever is on this, she thought it was worth dying for.”

The autopsy suite in the basement of the Jiangcheng Forensic Center was a cold, white-tiled world of stainless steel and antiseptic silence. Qin Ming worked alone, the overhead surgical lights casting a harsh, shadowless glare over the steel table. The victim’s body, now cleaned of river silt, lay supine under a white sheet. He had taken swabs, clipped fingernails, and combed through her hair for trace evidence. Now it was time for the internal examination.

He made the standard Y-incision with a scalpel, the blade gliding through the chilled skin and subcutaneous fat with mechanical precision. As he reflected back the tissue and exposed the thoracic and abdominal cavities, his suspicion was confirmed. The right kidney was absent, and the renal artery and vein had been cleanly severed and sutured shut with a type of monofilament thread that was not commonly used in domestic hospitals. The left kidney was still in place, pale and shrunken, indicating dehydration and prolonged malnutrition. The surgical technique was professional, almost elegant, but entirely devoid of any medical records or legal documentation.

“Nephrectomy performed by someone with surgical training,” he dictated into the overhead microphone, his voice echoing slightly in the empty room. “Suture material is 4-0 polypropylene, likely from a batch manufactured for veterinary or black-market use. No trace of a donor card or registry markings. Harvested, not donated.”

He removed the stomach and laid it on a separate dissecting board. A small incision into the gastric wall revealed the remnants of the victim’s last meal—a thin, greenish gruel that smelled faintly of algae and stale grain. And there, embedded in the mixture, were fragments of a transparent latex balloon, its surface partially dissolved by gastric acids. Just as he had predicted. She had been carrying the SD card internally, a desperate, anonymous courier in a network that treated human beings like disposable cargo.

He moved to the uterus and pelvic region. The victim had never given birth, but there was evidence of repeated, violent sexual trauma. Old, healed tears and fresh contusions told a story of systematic abuse over a period of months, perhaps years. Qin Ming’s jaw tightened, the only outward sign of the cold anger settling deep in his chest.

He finished the autopsy at five-thirty in the morning, stitching the body closed with the same meticulous care he gave every one of his patients. He pulled off his gloves, mask, and surgical gown, and walked to the adjacent lab, where the micro SD card sat in a drying chamber, cleaned of silt and moisture. He inserted it into a forensic card reader attached to an air-gapped computer, and watched as the screen flickered to life.

The card contained a single folder, named with a string of random alphanumeric characters. Inside the folder were dozens of files. Most were scanned images of identification documents—passports, national ID cards, student cards—belonging to young women from various countries in Southeast Asia and Africa. Their faces stared out at him, young, hopeful, unaware. There were also photographs of shipping containers, close-up shots of ledgers with hand-written entries in what looked like a coded shorthand, and a series of GPS coordinates mapping a route from the border region of northern Myanmar to the coastal city of Jiangcheng.

But it was the last file that made Qin Ming’s blood run cold. It was a simple text document, titled in English: “Inventory_January.” It listed dates, physical descriptions, blood types, and a column marked “Outcome.” Some entries had the word “Transferred” next to them. Others simply read “Expired.”

At the bottom of the list, one entry had been highlighted in yellow, the only one with a full name attached instead of a code number.

“Su Wan, age 16. Blood type O negative. Status: Pending. Note: High-value asset. School referral. Hold for Mr. Zhou.”

Qin Ming stared at the screen for a long time, the hum of the computer fan filling the silence. The name “Su Wan” was familiar. A missing person report had been filed over a year ago by her older sister, a university student named Su Ruo. The case had gone cold after months of fruitless investigation. The girl had simply vanished, swallowed up by a city that had seemed too busy to care.

He picked up the phone and dialed Captain Zhao’s number. “Zhao, it’s Qin. I’ve got the initial findings from the autopsy and the SD card. This is bigger than we thought. We’re not looking at an isolated organ harvest. It’s a trafficking ring. And there’s a school involved.”

The pause on the other end of the line was heavy. “A school?”

“Yes. I’m sending you the file now.” Qin Ming’s voice was low and hard. “Find out everything you can about the Greenleaf International Academy. I think the victim in the river was just the first loose thread. If we pull on it, the whole bloody tapestry might come apart.”

He hung up and turned back to the screen, his eyes fixed on the last line of the document. “School referral.” The words sat there like a cipher, innocent on the surface but pregnant with a dark, almost unimaginable implication. A place where children were supposed to be safe, transformed into a hunting ground. The riverside campus with its ivy-covered walls and manicured lawns was not a sanctuary; it was a stage where the cruelty of the adult world was rehearsed, refined, and ultimately enacted upon the most vulnerable bodies.

Qin Ming leaned back in his chair, his gaze shifting to the window, where the first grey light of dawn was beginning to seep through the blinds. Somewhere out there, in the gleaming towers and shadowed alleys of Jiangcheng, a machine was grinding human lives into profit. And somewhere, perhaps still alive in a dark, stifling room, a girl named Su Wan was waiting for a rescue that might never come, unless he could piece together the puzzle before the trail went cold.

He had no illusions about the time he had. The people who ran these operations were ruthless and efficient. They cleaned up their messes. The victim in the river was not meant to be found; she was a glitch in the system, a ghost who had refused to stay silent. Her clenched fist, her last, desperate act of defiance, might be the only weapon they had.

The computer beeped, snapping him out of his thoughts. A notification flashed on the screen: the password-protected partition on the SD card had finished cracking. A new folder appeared, labeled only with a single character: “周.”

Zhou. The same name from the “Hold for Mr. Zhou” note.

Qin Ming clicked it open, and the contents made his breath catch in his throat. It was a series of video files, their thumbnails showing dimly lit rooms, expensive furniture, and the terrified, tear-streaked faces of girls who looked barely old enough to be in high school. And in the corner of each frame, visible only for a split second in the first video, was a reflection in a window: the back of a man in a tailored suit, his hand resting on a desk where a golden nameplate sat, blurred but unmistakably engraved with the emblem of Greenleaf International Academy.

The video ended abruptly, and the screen went black, leaving only the reflection of Qin Ming’s own face staring back at him, etched with a mixture of weariness and a cold, simmering resolve. The campus was not a microcosm of the world’s cruelty; it was its epicenter. And the bell for the first lesson was about to ring.
