Chapter 4

The afternoon shadows lengthened across the white oak floors as Jin-woo and Lin walked back out into the central living area. The silence of the apartment felt heavy, laden with unspoken secrets and the phantom presence of a dead man who refused to rest. Madame Chen remained in the hallway, her silhouette framed by the pale light of the bathroom, staring at the floor where Jin-woo had first peered beneath the sideboard.
“She’s hiding something else,” Jin-woo murmured, keeping his voice low as he unclipped his radio to check for static. “People who burn documents usually keep a backup, especially someone as methodical as her. Order isn't just a preference for her; it’s a filing system for survival.”
“If she kept copies, they aren't on paper,” Lin replied, running her gloved fingers along the polished edge of the teak sideboard. Her mind was racing through possibilities. “Think about her behavior. Everything is physical, structural, spatial. Digital files can be hacked, printed pages can be tracked, but spatial anomalies leave traces.”
Jin-woo nodded, his eyes scanning the ceiling moldings. “The molding above the bookshelf. Look at the seam between the second and third panels.”
Lin followed his gaze. High up, where the white crown molding met the wall, a hairline fracture ran horizontally, completely out of alignment with the rest of the room’s architecture. It was a subtle flaw—the kind of imperfection that would drive someone with Chen’s psychological profile to the brink of madness.
“A drop-ceiling cavity,” Lin whispered. “Standard construction in these high-rises to house fire suppression lines, but in luxury units, residents sometimes convert them into private vaults.”
They didn't call out to Chen. Instead, Jin-woo retrieved a small pocket multi-tool from his belt, unfolding a flat-head screwdriver with minimal metallic clicking. He climbed silently onto a sturdy dining chair, reaching up toward the molding. His white gloves provided friction against the smooth wood as he applied gentle, upward pressure.
A soft click echoed through the room. The panel dropped half an inch, releasing a faint puff of stagnant air that smelled faintly of aged parchment and old leather. Down the hall, the soft tap of high heels announced Chen’s approach. She didn't run; she glided with terrifying composure, stopping at the edge of the dining area.

“I told you not to touch the architecture,” Chen said, her voice devoid of anger, carrying only a profound, chilling exhaustion.
“We’re looking for what’s killing you, Madame Chen,” Lin said, turning to face her squarely. “Or what’s going to kill us if we don't understand the rules of this house.”
