Chapter 3 - The Secret Beneath the Floorboards

The Dre estate was built in 1928, a sprawling stone fortress complete with service corridors, hidden dumbwaiters, and reinforced basements originally constructed during Prohibition. When Matthias and I married, I spent months exploring the house while recovering from a late-night surgical shift. I knew every squeaking plank, every service staircase, and every forgotten utility room.
And I knew where the gas line shutoff was located.
When the anonymous diagram arrived at my lawyer’s office, it had highlighted the estate’s basement sub-level directly beneath the ballroom and library. The note had called it collateral losses.
Matthias believed tonight was about signing the final papers that would transfer his father’s controlling voting rights to Hensley Logistics. But Fiona Vale wasn't working for Hensley. She was working for a syndicate of short-sellers who stood to make hundreds of millions if the Dre family empire imploded in a catastrophe of fraud and structural disaster.
I excused myself from the ballroom, bypassing the main hallway and slipping into the narrow service corridor behind the catering pantry.
The caterers were busy plating lobster medallions and roasted duck. None of them paid attention to the pregnant woman moving past the pantry shelves toward the cellar door.
I clicked on the flashlight app on my phone and descended the wooden stairs into the cold, stone-walled cellar.
The air smelled of aged wine, damp limestone, and something else.
Mercaptan.
The distinct, sulfurous odor added to natural gas to warn of leaks.
My heart slammed against my ribs.
They didn't just plan a financial takeover. They set a physical trap.
I stepped carefully across the concrete floor, holding my belly to keep my balance on the uneven surface. At the far end of the cellar, near the industrial boiler that heated the three-story estate, the main gas regulator valve sat mounted against the wall.
The secondary bypass valve had been tampered with.
A digital timer was spliced into the electronic solenoid control, blinking with a steady, pulsing amber light.
00:42:15
Forty-two minutes.
Forty-two minutes until the valve opened completely, venting high-pressure natural gas directly into the boiler intake. The moment the boiler ignited to heat the grand ballroom during the midnight toast, the entire eastern wing would be obliterated.
Arthur Dre was sitting directly above this room.
Matthias was upstairs drinking champagne.
And Fiona had ensured that all emergency exits in the eastern corridor were locked from the outside under the guise of "private security protocols" for the acquisition signing.
I took out my phone and took four high-resolution photos of the spliced wires and the serial number on the illegal detonator solenoid.
Then I pulled a pair of trauma shears from my handbag—a habit I had never broken since my first day in the emergency department.
I didn't cut the wires. Cutting a live circuit on a timer could trigger an immediate fail-safe release.
Instead, I reached for the manual main cutoff wheel located six feet upstream of the bypass.
It was rusted. It hadn't been turned in years.
I gripped the iron wheel with both hands, planted my feet on the cold concrete, and hauled backward with everything I had.
Pain flared through my lower back. My daughter shifted violently inside me.
“Come on,” I grunted, tears springing to my eyes. “Come on!”
The iron wheel groaned. Metal scraped against metal.
With a sharp clack, the valve turned ninety degrees, shutting off the supply from the street before it could ever reach the tampered solenoid.
I sank to my knees on the cold floor, panting, my hands trembling against my dress.
Suddenly, footsteps echoed on the cellar stairs.
Slow.
Deliberate.
Heels clicking against stone.
“You always were too observant for your own good, Serena.”
May you like
I turned my flashlight toward the staircase.
Fiona Vale stood at the bottom step, holding a small silver pistol in her gloved right hand.
