Chapter 4 - THE SUBTERRANEAN RACEThe air grew thick, cold, and damp as they rushed down the narrow iron steps. The sound of rain faded, replaced by the low, resonant hum of the mansion's subterranean water pumps.
Daniel pulled his inspection flashlight from his vest, throwing a sharp beam of white light down the endless spiral steps. Below them, the stone walls were rough, unpolished limestone—the true bedrock of the Mercer Estate.
"If the deed gets uploaded at midnight," Evelyn panted, her high heels snapping as she tore them off to run barefoot on the cold stone, "the land registry server in Austin automatically files the title change. Once it’s filed, Vanguard’s shell company automatically signs a pre-arranged foreclosure lien. They will execute a demolition order on this entire property by sunrise to build a commercial development!"
"Why would they demolish a fifty-million-dollar historic mansion?" Daniel asked, his heart sinking.
"Because of what's UNDER it!" Evelyn revealed, her voice echoing off the damp stone. "Three months ago, during a survey for the new subway line, state geologists found a massive lithium deposit right under your father’s land parcel. It's worth over two billion dollars! Your father refused to sell. He wanted to preserve the historical wetlands above it. That's why they killed him, Daniel! That's why they need the estate wiped off the map!"
The truth hit Daniel like a runaway freight train. It wasn't about a house. It was never about a house. It was about a multi-billion-dollar energy goldmine that sat directly beneath his family’s bloodline.
They reached the bottom of the stairs, bursting into the sprawling, arched brickwork of the underground wine cellar. Massive wooden barrels lined the walls, smelling of aged oak and vintage cabernet.
"Where is it?!" Evelyn frantically looked around at the solid concrete floors and brick walls. "We have ten minutes, Daniel! Ten minutes!"
11:50 PM.
Daniel ignored her panic. He walked straight to the southern support pillar—the massive octagonal column holding up the weight of the entire eastern wing of the mansion.
He shined his flashlight on the base of the pillar. The concrete here was slightly a different shade of grey than the surrounding floor. It had been poured far more recently.
He dropped to his knees in his dirty work pants. He pulled out his industrial contractor’s multi-tool—a heavy-duty titanium utility hammer with an integrated cold chisel.
"Daniel, you can't break through reinforced cured concrete with a pocket tool in nine minutes!" Evelyn cried out in despair. "It’s impossible!"
"My father was an architect, Evelyn," Daniel said grimly, striking the base of the pillar with the titanium chisel. CLANG! "He wouldn't bury an emergency drive in solid cured high-psi concrete. He knew I’d come for it in a work vest, not a jackhammer."
CLANG! CLANG!
The outer shell of thin mortar flaked away like dry bark. Beneath it lay not solid concrete, but a heavy, water-tight steel utility junction box embedded into the pillar, locked with a mechanical four-digit combination dial.
"A lock!" Evelyn gasped, dropping to her knees beside him. "What’s the code? Do you know his birthday? Your mother's birthday?"
Daniel looked at the four metal wheels on the combination lock.
He thought back to the portrait in the study upstairs. The silver watch on his father’s wrist.
4:15.
He quickly spun the metal dials: 0 - 4 - 1 - 5.
CLICK.
The heavy steel box sprang open. Inside, resting on a bed of black velvet, sat a heavy, military-grade encrypted flash drive, painted gold, with a high-speed fiber-optic connector sticking out of the end. Attached to it was a handwritten note in his father's bold, clear handwriting:
"To my son, Daniel. If you are reading this, the men who wear suits have tried to take what we built with our hands. Plug this into the regional mainframe. It doesn't just block the transfer—it exposes every politician, lawyer, and judge on Vanguard's payroll. Stand tall, Mercer."
Tears blurred Daniel’s vision for a fraction of a second, but he wiped them away instantly.
"We have the drive!" Evelyn yelled, checking her phone.
11:54 PM. Six minutes remaining.
"Now we just need to connect it to the master internet relay," Daniel said, standing up. "Where is the main network uplink for the house?"

Evelyn’s face turned deathly pale. "It's... it's in the main ballroom. On the stage behind the DJ booth."
Daniel looked up toward the arched brick ceiling. "Right underneath three hundred fake guests, Charles Whitmore, and a squad of armed mercenaries."
