Lian sat cross-legged on the floor, a small lamp throwing soft light over the open laptop in front of her. Kai was still at the table, surrounded by a mess of files and notebooks that looked older than both of them combined.

  He pushed his glasses up the bridge of his nose and muttered, “You ever notice how Mom never labeled anything in a normal way? Half these folders look like grocery lists.”

  Lian didn’t look up. “She was hiding them. Ordinary titles don’t raise suspicion.”

  “Yeah, but ‘Rice Inventory 2004’ isn’t exactly a great cover when you open it and find encrypted code sheets inside.”

  She smiled faintly. “She trusted you’d figure that part out.”

  Kai leaned back in his chair, eyes tired but bright. He’d been like this since they found the old box behind the wall panel two nights ago. Ever since he cracked the false bottom and found a drive with their mother’s handwriting taped to it, he’d been obsessed.

  “You think Dad knew?” he asked quietly.

  Lian looked at him now. His tone wasn’t curious. It was careful.

  “I think they both knew,” she said. “But maybe not everything.”

  Kai nodded slowly. He clicked on another file, and a wall of text filled the screen. Rows of code, numbers, and symbols. Lian leaned closer, trying to make sense of it.

  “Encryption patterns,” Kai said. “They’re built on old surveillance protocols. But look at this—” He pointed to a line that repeated every few pages. “HK-GATE. That was Dad’s project name, right?”

  Lian frowned. “You were too young to remember.”

  “I read about it in one of the old news clippings. Some joint government experiment. Said it was about city traffic management. But that’s not what this looks like.”

  She was quiet for a long time. The hum of the rain filled the space between them.

  “Dad worked for the agency before it went private,” she said finally. “He used to say he was building something to keep people safe. Mom didn’t believe it anymore by the end.”

  Kai opened another folder. Inside were faded scanned letters, some with official headers, some handwritten. One caught his eye.

  He clicked it open.

  The screen showed a message written in their mother’s neat cursive:

  “If they come for us, it means the project is no longer ours. Hide the keys where memory won’t fade.”

  Kai whispered, “Hide the keys…” He looked up. “She meant this, didn’t she? These drives.”

  Lian’s voice softened. “Maybe. Or something else.”

  Kai’s knee bounced. He had that restless energy again, the one he got whenever he felt close to something. “I want to decrypt the full set. There’s another layer on these files. Look.”

  He typed fast, lines of code scrolling like rain on the screen. Lian watched the way his fingers moved. Her brother had always been like that. Too quick. Too smart for his own good.

  If you spot this tale on Amazon, know that it has been stolen. Report the violation.

  Minutes passed before the first image appeared. It was a schematic.

  At first glance, it looked like a map of circuits. But when Kai zoomed out, Lian realized it was a map of Hong Kong.

  She straightened. “That’s the city grid.”

  “Exactly,” Kai said, his voice hushed. “These aren’t just surveillance nodes. These are… control points. See these intersections? They connect to private sectors—communications, finance, even hospitals.”

  Lian’s jaw tightened. “Our parents were working on this?”

  Kai nodded slowly. “At least, the foundation of it. Before it was taken.”

  He clicked again, opening a log file. Dates scrolled by. Some went back fifteen years. The last entry was marked March 14, 2013. The day their parents died.

  Lian felt her stomach twist. “Turn it off.”

  Kai hesitated. “Lian—”

  “Now.”

  He froze at her tone, then closed the window. The screen went dark.

  Silence pressed between them. Lian stood and walked to the window. The city outside was blurred with rain, neon lights bleeding across the glass.

  Kai’s voice was small when he spoke. “You think this is what got them killed?”

  She didn’t turn. “I think there’s a reason Mom hid it from everyone. Even us.”

  He came to stand beside her. “We could figure it out, you know. Piece it together. Maybe it’s—”

  “Maybe it’s a trap,” she cut in. “Every time we dig, something follows.”

  Kai stared at her reflection in the glass. “You’re scared.”

  Lian’s eyes flicked toward him. “I’m cautious.”

  “It’s the same thing.”

  She gave a short laugh, one that didn’t sound like humor. “No. Fear freezes you. Caution keeps you alive.”

  He wanted to argue, but he knew she was right. She always was when it came to survival. Still, he couldn’t shake the thought that the answers they’d been chasing their whole lives were sitting right there in front of them.

  He sighed. “Then what do we do with it?”

  Lian turned from the window. “We move it. Hide it again. Somewhere safer.”

  “Where? The last time we hid something, we ended up on half the city’s security feeds.”

  “I’ll take care of it,” she said simply.

  He frowned. “You mean you’ll do it alone.”

  “I mean you’ll stay here and keep your head down.”

  Kai’s voice rose. “You think I’m a kid again? I’ve been doing this as long as you have.”

  Her expression softened. “You’re still my brother.”

  “That’s not an answer.”

  “It’s the only one I have.”

  They stared at each other for a long moment, neither willing to back down. Then Kai sighed and rubbed the back of his neck. “You really think hiding it will make a difference?”

  “I think someone already knows we found it,” she said quietly.

  He blinked. “What?”

  She nodded toward the laptop. “The signal bounced twice while you were decrypting. Once through Kowloon, once through Central. Someone pinged the line.”

  Kai swore under his breath. “Could just be a random trace.”

  “Could be. Or not.”

  He shut the laptop hard, the sound sharp in the quiet room.

  “Alright,” he said, his tone tight. “We move it tonight.”

  Lian nodded. “Pack light. We’ll make it look like a relocation.”

  “Another one,” he muttered.

  “Just another one,” she echoed, and for a moment her eyes softened, almost nostalgic.

  Outside, the rain began to fade. The city lights flickered through thinning clouds, and somewhere below, a siren wailed, swallowed by the noise of the streets.

  Lian reached for the drive, slipped it into her pocket, and looked at her brother. “Get some rest before we go.”

  Kai smirked faintly. “You know I won’t.”

  “I know,” she said, and turned off the lamp.

  The room sank into darkness, the faint blue glow of the city washing over their faces as the rain finally stopped.
