Chapter 5 - The Antidote's Price

The red emergency strobes along the cellar walls suddenly flickered to life, bathing the stone corridor in blood-red pulses. The hum of the estate’s backup generator surged through the floor like a dying heartbeat.
""The air vents,"" Marcus said, tossing his cigar into a puddle of stagnant water. ""They've engaged the fire suppression protocol. Carbon dioxide lockdown. They aren't shooting their way down here; they're going to suffocate us.""
Above them, the heavy steel fire shutters slammed shut with hydraulic thuds that reverberated through the foundation. The hiss of gas entering the ventilation shafts grew louder.
Lily coughed once, a dry, fragile sound that struck Ethan harder than any physical blow. He knelt instantly, scooping the little girl back into his arms and pulling a silk pocket square from his jacket. He splashed it with water from a copper pipe valve and pressed it over Lily’s mouth and nose.
""Breathe slow, little bird,"" Ethan commanded gently. ""Keep your eyes on me.""
""Uncle Ethan... it smells like bitter almonds,"" Lily whispered, her eyelids fluttering with unnatural lethargy.
Ethan’s head snapped toward Marcus. ""That isn't carbon dioxide. That’s hydrogen cyanide. Victoria didn't just authorize a fire drill—she released the chemical compound stored in the basement laboratory.""
""Julian knew the security bypass,"" Marcus swore, fumbling at the wall control panel. His fingers typed in an eight-digit override, but the console spat back a screeching error tone: ACCESS DENIED - BIOMETRIC OVERRIDE ENGAGED.
""They used your thumbprint from the shattered champagne glass upstairs,"" Marcus growled, coughing as the sweet, deadly odor of cyanide began to drift through the ceiling grates. ""We have less than four minutes before the concentration in this low corridor becomes lethal.""
Ethan looked around the cellar. There was only one exit that didn't rely on electronic authorization: the old coal chute leading out toward the greenhouse garden. But the chute was blocked by a cast-iron grate secured with a mechanical combination lock that hadn't been turned in thirty years.
""The lock,"" Ethan said, his voice dropping into razor-sharp focus despite the burning sensation creeping into his own throat. ""Marcus, what was the founding date of the third foundry?""
""I don't remember!"" Marcus coughed violently, slumping against the stone wall, his face turning an ashen gray. ""That was eighty years ago!""
Lily reached out with a trembling hand, her fingers brushing the cold iron dial of the chute. ""Seven... two... four... nine..."" she murmured in a daze.
Ethan stared at her. ""Lily?""
""Mommy sang it,"" Lily wheezed, her chest heaving. ""Every night before bed. The numbers of the iron door where the flowers grow.""
Ethan didn't question the miracle. He spun the heavy rusted dial with savage speed: 7... 2... 4... 9.

With a deafening mechanical clunk, the iron pins fell away. Ethan slammed his shoulder into the grate, blowing it open into the freezing night air. But as he turned to haul Marcus through, a shadow fell over the opening from the garden above.
A sleek silencer pressed directly against Ethan’s forehead.
