The rain that had started the night before had not stopped. It came down in long, gray sheets that turned the alleyways into shallow rivers. Kai stood by the cracked window of the safehouse and watched the water trace slow lines down the glass. The city beyond was quiet in that uneasy way Hong Kong got when it rained too much, when people stayed indoors and the neon signs reflected on the pavement like ghosts.

  Lian sat behind him at the small table with an old laptop. She had been typing for over an hour, silent except for the low hum of the fan. The place smelled like damp concrete and cheap instant coffee.

  Kai finally turned away from the window. “You think it’s real?”

  Lian didn’t look up. “The files?”

  He nodded.

  “I don’t know yet. Mother hid them well. That alone means something.” She stopped typing, leaned back, and rubbed her eyes. “Every time I open a new folder it feels like I’m reading someone else’s life.”

  Kai sat across from her. “Maybe that’s the point. She didn’t want us to find it until now.”

  Lian gave a small smile. “Or she never wanted us to find it at all.”

  The hard drive Kai had discovered was still sitting on the table, wrapped in a cloth. He had found it inside the walls of their old apartment, sealed inside a plastic container beneath a loose floorboard. The discovery had been half chance, half instinct. The device was old, pre-encryption era, but it still worked. What it contained was harder to understand.

  Most of the files were labeled in code, strings of numbers and letters that looked like system logs. Others were notes written in their mother’s handwriting. Reports, test results, fragments of what looked like official correspondence. Every word hinted at something larger, something organized, something hidden in plain sight.

  Kai leaned forward. “What did you find about Father?”

  Lian opened a folder and turned the screen toward him. “Not much. Just a few scanned documents. Letters from someone named Qian. He was involved in their research.”

  “Government?”

  “Maybe. But look here.” She pointed to a page filled with formulas and annotations. “This isn’t about tracking people in the usual sense. It’s behavioral prediction. Mapping human decisions through data patterns. If you feed enough information into it, you can forecast how someone will act.”

  Kai frowned. “You mean like predicting crimes before they happen?”

  “Or knowing which people might rebel before they do. It’s control, not prevention.”

  He looked away, unsettled. “And LSK got their hands on it.”

  “Maybe not yet. But if they were after our parents, this could be why.”

  The rain hit harder against the window. Lian closed the laptop and stood. “I need to see something.”

  “Where?”

  Support the author by searching for the original publication of this novel.

  “The old university building. She used to work in Lab B there. Maybe there’s something left.”

  Kai hesitated. “That place has been sealed off for years.”

  “Exactly. Which means no one’s bothered to clean it out.”

  He sighed and reached for his jacket. “Fine. But we go quiet.”

  The university sat on a hill overlooking the harbor, a collection of aging concrete buildings that looked more like bunkers than a place of learning. By the time they reached the old lab block, the rain had slowed to a mist. The doors were chained shut, but that had never stopped them before.

  Kai picked the lock while Lian kept watch. The sound of the metal snapping was faint, lost in the wind. Inside, the hallway smelled of dust and rusted pipes. Their footsteps echoed softly on the tiles.

  Lian moved first, flashlight cutting through the dark. She had walked this corridor before, when she was younger, when her mother used to work here late at night. She remembered the smell of chemicals and the way her mother would hum quietly while writing notes. It had felt safe then. Now it felt haunted.

  The door to Lab B was still marked with their mother’s name, though half the letters had peeled away. Lian pushed it open and stepped inside.

  Everything was as it had been left years ago. Tables lined with old monitors, glass equipment covered in dust, stacks of papers yellowed by time. Lian felt a strange pull as she walked toward her mother’s old workstation.

  Kai ran his hand along a shelf. “No one’s been here in forever.”

  Lian crouched by the desk and opened the drawers. Most were empty except for faded stationery and broken pens. Then she found it — a small wooden box, hidden behind a loose panel.

  She lifted it out carefully and set it on the table. It was plain, unmarked, but locked with a tiny brass latch. Kai found a screwdriver and pried it open.

  Inside were old photographs.

  Lian picked one up. It showed their parents standing in front of a whiteboard filled with equations. Her mother was smiling, her father serious but calm. Behind them were two other people — a man and a woman neither of them recognized. On the back, written in blue ink, was a single word: “Beta.”

  Kai reached for another photo. This one showed the same group, but the setting was different — a facility, not a classroom. There were machines in the background, heavy-looking servers. Someone had circled a small logo in red ink.

  “LSK,” Kai said quietly.

  Lian stared at it. The symbol was faint but unmistakable.

  “So they were partners,” he said. “Or at least collaborators.”

  Lian felt her stomach twist. “If that’s true, everything we thought we knew about them changes.”

  Kai leaned against the table, his jaw tight. “They weren’t just victims. They were part of it.”

  Lian shook her head. “No. They must have turned on LSK later. Maybe that’s why they were killed.”

  They stood in silence for a while, the sound of dripping water echoing from the pipes.

  Kai finally spoke. “There’s more.” He reached into the box again and pulled out a small data chip taped to the bottom. “Looks like another archive.”

  Lian took it carefully. “We’ll check it back at the safehouse.”

  When they stepped out of the lab, the sky was beginning to clear. The rain had stopped, leaving the air heavy with the smell of wet earth.

  As they walked back down the hill, Lian glanced once more at the old building. She felt both closer and farther from her mother than she ever had before.

  Kai walked beside her, silent. He carried the box under his arm, the photos shifting softly with each step.

  Neither of them spoke until they reached the car. Lian started the engine, and the city lights came into view again below them, shimmering on the damp streets.

  Kai looked out the window. “You think we’ll ever get to the bottom of this?”

  Lian didn’t answer right away. She watched the reflection of the headlights on the windshield and said quietly, “We have to.”

  The car moved down the winding road, leaving the university behind like a shadow swallowed by fog.

  The box sat between them, small and silent, but heavy enough to change everything once it was opened.
