At 7:14 on a rainy Friday night, my millionaire husband spent $38,600

"You suicidal bastard," Julian hissed, shoving Charles backward onto the concrete floor.

Charles didn't fight back. He sat against the severed server rack, wiping a bead of blood from his split lip, smiling like a demon in the ruins of his own creation. "Grant doesn't want the money, Claire. He wants the bloodline erased. Once you and Maya are gone, the entire estate defaults to the Sterling corporate trust. He will raze this chapel to the ground and bury Vault 00 under five feet of industrial cement."

"Maya," I gasped, the cold realization piercing through the adrenaline. "Maya is in the vehicle above."

"Miller, where is she?" Julian barked, stepping toward the mercenary.

"She’s with my partner in the lead Suburban, concealed behind the old carriage house," Miller said, his eyes shifting toward the spiral staircase as the muffled rhythm of distant gunfire echoed down the shaft. "They have suppressed rifles. They’re sweeping the grounds room by room. We have maybe three minutes before they breach the chapel nave."

"Can we seal this door?" I asked, looking at the massive titanium slab.

"If you seal the blast door from the inside, you buy twelve hours of air, but you trap yourself in a tomb," Julian said grimly. "Grant has thermal imaging. They'll bring heavy drilling equipment and drop neurotoxin through the ventilation shafts. We have to go up. We have to hit them before they establish a perimeter."

I looked down at Charles, my own father, who sat watching us with theatrical detachment.

"You stay here," I said to him, my voice devoid of emotion.

"Claire," Charles mocked, tilting his head. "Without me, you can't access the Zurich Protocol. The four hundred million requires my thumbprint alongside yours. You walk out that door without me, and you leave the Delacroix fortune behind forever."

"Keep it," I said. "I spent ten years surviving a millionaire who thought money bought souls. I won't spend the next ten serving another."

I tossed the bronze key into the dark corner of the vault behind the servers, where it clattered into a drainage grating and vanished into the wet earth below.

Charles’s smug smile vanished, replaced by an expression of pure, unadulterated horror. "No! Claire, you fool! You've ruined us!"

"Julian, move," I said, ignoring my father's screams.

We followed Miller up the iron spiral staircase, the air growing colder and sharper with every turn. The heavy smell of gunpowder drifted down into the shaft. When we reached the Saint Michael relief, Miller held up a fist, signaling a halt.

He peeked through the stone crack into the chapel.

Two armed men in tactical gear, carrying suppressed MPX submachine guns, were moving down the center aisle, their weapon lights cutting through the darkness. Beyond them, through the shattered stained-glass windows, red and blue strobe lights swept across the autumn trees—not police cruisers, but the auxiliary emergency beacons of Grant Sterling’s private security convoy.

"Two targets in the sanctuary," Miller whispered. "Three more covering the courtyard. The vehicle with your daughter is fifty yards east, pinned behind the stone wall."

"Can you take them?" Julian asked.

"I can take the two in the aisle," Miller replied, racking the bolt of his rifle silently. "The courtyard is a turkey shoot unless we create an immediate diversion."

I looked at the Glock in my hand, then at the antique stone altar thirty feet away, where an ancient bronze candelabra rested beneath the rotted velvet cloth. Connected to the wall behind it was a cast-iron natural gas pipe, installed in the 1920s to heat the family chapel during winter funerals.

"Julian," I whispered, pointing to the rusted brass valve protruding from the stone masonry. "The gas main. Is it still live?"

Julian’s eyes widened as he understood. "The whole estate is fed by an industrial propane reserve behind the stables. If you open that valve..."
