The barefoot little boy looked completely out of place among the diamonds, tuxedos, and champagne flutes surrounding me at the Plaza’s Grand Ballroom.

The speakers on the laboratory’s communication console hissed to life with static, followed by Julian’s smooth, aristocratic voice echoing through the subterranean bunker.

“Charles? I know you’re down there, cousin. The GPS beacon in that lovely bespoke jacket of yours led us straight to your little family reunion.”

Clara flinched, her body seizing with terror. “He’s working with them, Charles. He’s been funding them for twenty years. Arthur found out about the offshore clinical trials... that’s why Julian tried to sink his yacht.”

The puzzle pieces snapped together with horrifying precision.

Twenty years ago, Whitmore Pharmaceuticals had been on the verge of bankruptcy before a miraculous breakthrough in synthetic cellular regeneration saved the company. I had believed Arthur died in an accident. In reality, Julian had orchestrated the hit to take control of the research, forcing Arthur and Clara to flee into the wilderness with the only viable living strain of the regenerative pathogen.

And that strain was now running through Leo’s veins.

“Julian,” I said into the console microphone, keeping my tone dead and steady. “You brought heavy weapons to the Adirondacks. Did you really think you could slaughter a child and walk away as CEO?”

A cold chuckle rattled through the speakers.

“Slaughter him? Good heavens, no, Charles. That boy is worth three hundred billion dollars. His cellular metabolism can repair necrotic tissue in seconds. Do you have any idea what every dictator, oligarch, and dying billionaire on this planet will pay for a single vial of his blood? You were just the test subject tonight. A live demonstration to prove the old research was still functional.”

Julian’s voice hardened, stripping away the polite veneer of high society.

“You’ve had your miracle, Charles. You can walk again. Be grateful. Send the boy up the stairs, and I’ll let you live out your days on an island in the Pacific. Refuse, and my team will drop thermite charges down that ventilation shaft. You’ll be melted into the concrete before sunrise.”

Leo pressed his face into my thigh, his small hands trembling against my slacks.

“Uncle Charles,” he whispered. “Don’t let them put me back in the box.”

I looked at Clara. Her breathing was becoming more labored by the second; the trauma from her interrogation had triggered internal hemorrhaging. She wouldn't survive another hour without advanced surgical care.

“How many men does he have, Lev?” I asked over the local earpiece.

“Twenty-four operators,” Lev’s voice crackled back from his concealed position near the tree line. “All former military contractors. Heavy armor, night vision, automated fire support. If you come up the main stairs, you walk into a meat grinder.”

“Is there an auxiliary exit?” I asked Clara.

She nodded weakly toward the back of the lab, pointing toward an old ventilation conduit behind a metal rack of chemical reagents. “It leads... to the old drainage culvert by the river. But it’s blocked by a blast gate. It requires... Arthur’s biometric signature.”

“Or mine,” I realized.

Arthur and I were identical twins in our genetic markers—a quirk of biology that our father had always used to program our family security vaults.

“Lev,” I whispered into the mic. “Can you create a distraction on the north perimeter? Draw their heavy fire for ninety seconds.”

“I have two fragmentation grenades and their auxiliary fuel truck in my crosshairs, Mr. Whitmore,” Lev replied with grim satisfaction. “Give me thirty seconds to set the charge.”

I turned to Clara. “Can you walk?”

“No,” she whispered, coughing blood onto her chin. “Leave me, Charles. Save Arthur’s son. That’s all that matters.”

“A Whitmore doesn't leave family behind,” I said.

I knelt down, took Clara by the shoulders, and lifted her onto my back, securing her arms around my neck with my belt. Then I picked up Leo with my left arm, racking the slide of the Glock with my right hand against my thigh.

Six years of paralysis had made me appreciate every fraction of a millimeter of muscle fiber. My legs felt like forged steel.

“Ten seconds, boss,” Lev whispered through the comms. “Five... four... three... light it up.”

Above us, the night erupted.

A massive fireball tore through the canopy as the fuel truck detonated. The shockwave rattled the bunker's concrete ceiling, showering us in dust. Gunfire broke out instantly—Lev engaging the perimeter with ruthless, guerilla precision.

“Move!” I commanded myself, sprinting toward the rear blast gate.

The electronic scanner was covered in grime. I slammed my palm against the optical glass.
