I fell to my knees, the frigid concrete floor biting into my skin, but the cold inside my chest was far worse.

On the screen, my father—the quiet, gentle engineer who used to build wooden birdhouses with me in our cramped backyard—leaned down and kissed Evelyn’s forehead. The video timestamp flickered in crisp yellow digits across the bottom: June 12, 2001.

«She’s perfect, Arthur,» Evelyn’s voice drifted through the monitor’s tiny speakers, soft and filled with a terrifying, tender warmth I had never heard from her before. «Subject 04 is stable. The genetic sequencing took.»

«She isn’t a subject, Evelyn,» my father replied softly, cradling the newborn. «She’s our daughter. And I’m taking her away from this company before you turn her into what you’ve become.»

The audio snapped into static as the clip abruptly ended, replaced by a blinking prompt in the center of the screen: BIOMETRIC CONFIRMATION REQUIRED FOR ARCHIVE UNLOCK.

A sudden, sharp shadow fell over the threshold of the hidden room.

I spun around, my back slamming against the desk as my hand blindly searched for a weapon, landing on a heavy metal paperweight.

Julian stood in the doorway, clutching his bleeding shoulder, his face ghastly pale. But it wasn’t the blood loss making him look like a ghost. His eyes were wide, fixed on the monitor screen behind me, filled with a sudden, devastating realization.

«You knew,» I whispered, my voice trembling with a mixture of rage and utter betrayal. «All this time… you knew who I was.»

«Maya, no—» Julian took a staggering step forward, reaching out a hand, but stopped when I raised the metal paperweight, my knuckles white.

«Don’t come any closer!» I screamed, tears finally spilling over my eyelashes. «You married me! You brought me into this house! Was I just a missing piece of your father’s dark legacy? Was I just a code to open your bloody vaults?!»

«I didn’t know until three weeks ago!» Julian choked out, a raw, desperate sob tearing from his throat. «I swear to you, Maya! I found my father’s journals in the offshore accounts. I thought Evelyn was trying to destroy you because you were an outsider… but she was hunting you down to claim the bio-encrypted patents your father stole when he faked your death!»

Before I could process his words, a muffled thud echoed from the library above, followed by the sickening sound of metal grinding against metal.

The heavy stone mantel behind us suddenly slammed shut, sealing the hydraulic door. The ambient lights in the sterile room instantly shifted from white to a blinding, flashing crimson.

A mechanical voice synthesized through the overhead speakers: WARNING. PERIMETER BREACH. CONTAINMENT PROTOCOL ACTIVATED. AIR FILTRATION SYSTEM DISCONNECTED.

Julian lunged toward the control panel beside the desk, frantically punching numbers into the wall unit, but the screen only flashed red error text. «The federal agents didn’t clear the house,» he gasped, his lungs straining as a faint, sweet-smelling white mist began to hiss from the ceiling vents. «Evelyn’s people… they weren’t trying to shoot us. They were driving us down here.»

«The baby!» I screamed, lunging for the closed stone door, hammering my bare fists against the reinforced wall. «They have my baby!»

«Maya, stop! You’ll inhale the gas faster!» Julian grabbed my waist, pulling me away from the door. He yanked the collar of his blood-stained shirt over his nose and mouth, forcing me down to the lowest point of the floor where the air was clearer. «Listen to me! The keycard you used… where is it?!»

I pointed with a shaking finger to the glass desk. The silver card with the obsidian crest was sitting right next to the glowing monitor.

Julian scrambled across the floor, snatching the card. He didn’t swipe it into the desk or the door. Instead, he slammed his fist into the glass screen of the monitor, shattering it into a web of glowing fractures, and jammed the silver keycard directly into the exposed circuit board behind the display.

Sparks erupted in a violent shower, blinding us for a fraction of a second.

The crimson lights killed out completely, plunging the room into total, suffocating darkness. The hissing of the toxic gas stuttered and stopped.

For five excruciating seconds, the only sound was our frantic, ragged breathing in the pitch black.

Then, a quiet clack echoed from the floorboards beneath our feet.

A tiny hatch in the concrete floor sprung open, revealing a narrow, vertical metallic shaft leading down into the darkness, illuminated only by a single green LED light at the bottom.

«A escape tunnel,» Julian panted, his hand finding mine in the dark and gripping it with desperate strength. «Your father built a fail-safe.»

I looked down into the narrow abyss, then back toward the sealed stone door above, where the faint sound of heavy, rhythmic footsteps echoed from the library floor above us. Someone was standing right on the other side of that stone wall.

Suddenly, a smooth, familiar voice bled through the room’s intercom speaker, completely undisturbed by the short-circuit.

«Did you really think your father was the hero of this story, Maya?» Evelyn’s voice purred, clear and chillingly close. «He didn’t save you from me. He hid you from the people who created both of us. And right now, your daughter is in a helicopter heading straight to them.»

My heart stopped.

A sharp, metallic clinking sound echoed from the top of the escape hatch—someone above had just dropped a small, heavy object into the shaft.

It bounced down the metal rungs with a rhythmic, horrifying rhythm: clack, clack, clack.

A live tear gas canister rolled to a stop right at the edge of the hatch, its pin already pulled.
