Chapter 10: The Locked Door

The heavy pocket door slammed shut with a deafening rattle, and the metallic sound of a deadbolt sliding home echoed sharply inside the confined space. Clara spun around, dropping the rotary phone as she lunged toward the doorway. She threw her weight against the wooden panel, but it didn't budge an inch.
"David! Open this door right now!" Clara shouted, slamming her palms flat against the wood. "What do you think you're doing?"
Through the thin wood, David’s voice came muffled but completely calm. "I'm sorry, Clara. But your father’s right. If that box gets opened, everything we've built—everything I sacrificed to keep this property afloat—goes down the drain. You're safer in there until Pendelton arrives."
"You sold us out," Elena hissed from the dark corner of the room, her voice trembling with a mixture of terror and white-hot fury. She slammed her foot against the base of the door. "Open this door, David, or so help me God, I will tear every contract you own to pieces!"
"Elena, just stay quiet," David pleaded from the hallway. "The service elevator is already moving. Your father is coming down, Clara. He wants to talk to you alone."
Clara turned away from the door, her breath coming in short, panicked gasps. She looked back toward the two-way mirror. On the other side, the old man in the wheelchair hadn't moved an inch. His sunken eyes remained fixed on her, glowing faintly under the harsh fluorescent lights of the surveillance room. He raised a frail, trembling hand and pressed his palm flat against the glass, exactly where Clara’s face was reflected.
"He can't hear us through the acoustic glass," Clara muttered, scanning the cluttered desk for anything heavy enough to smash the mirror. Her fingers brushed against a heavy iron wrench lying next to the ledger.
"Clara, don't!" Elena warned, stepping back as she realized what Clara was planning. "If that glass breaks, whatever is on the other side—water, gas, or worse—is going to flood this room. Look at the pressure gauges on the wall!"
Clara glanced up at the circular dials mounted above the desk. The pressure needle for the main pool intake valve was pinned deep in the red zone, vibrating violently against the glass casing. The entire utility room was connected directly to the pool's primary circulation system; a single structural breach here would send thousands of gallons of crystal-clear water cascading into the alcove.

"He's flooding the foundation," Clara realized, her blood running cold. "He didn't trap us here to talk. He trapped us here to drown the evidence."
As if on cue, a loud, metallic screech echoed from beneath the floorboards. Bubbles began to rise violently from a floor drain near Clara's feet, followed by the unmistakable sound of rushing water filling the pipes behind the walls.
