Part 3: Locker Number Four

A sudden, sharp metallic CLANG echoed from the top of the stairs, snapping the silence like a whip.

Sarah let out a muffled scream. Above them, the heavy steel hatch slammed shut, plunging the staircase into absolute darkness. The sound of a heavy padlock clicking into place echoed down the shaft.

“Someone locked us in!” Sarah panicked, rushing back toward the stairs, her hands scrambling blindly against the cold stone. “Frank! Someone was upstairs!”

Frank drew the silver revolver from the desk, checking the cylinder. Six rounds. Fully loaded. He walked toward the steel lockers lining the wall, his light sweeping across the rusted tags: 01, 02, 03… 04.

Locker 04 was different. It wasn’t just padlocked; it had three heavy iron deadbolts welded across its front, and a thick electronic keypad glowing with a faint red standby light.

Suddenly, a raspy, mechanical hum vibrated from inside Locker 04.

“Frank, leave it alone!” Sarah sobbed from the bottom of the stairs, pounding her fists against the locked trapdoor above. “We need to find a way out!”

“There is no other way out, Sarah,” Frank said grimly, looking at the keypad. “Father didn’t build this room to hide his money. He built it as a cage.”

A muffled, rhythmic thumping began from inside Locker 04. Thump. Thump. Thump. It sounded like something soft and heavy beating against the steel door from the inside.

Then, a voice drifted out through the thin air vents of the locker. It wasn’t a monster’s growl. It was a woman’s voice—soft, sweet, and terrified.

“Is someone out there?” the voice whimpered. “Please… he locked me in here ten years ago. Please let me out.”

Sarah turned around, her eyes wide in horror. “Oh my god… Frank, there’s a woman in there!”

Part 4: The Truth in the Dark

Frank raised the gun, pointing it straight at the steel door of Locker 04. “Who are you?” he demanded, his voice cold.

“My name is Clara,” the voice sobbed from inside the locker. “Your father… he kidnapped me. He kept me down here. Please, the code is on the back of his watch! Check his desk!”

Sarah scrambled toward the desk, frantically shining her phone’s light until she found a gold pocket watch sitting in a small velvet display box. She snapped it open. Engraved on the inside casing was a four-digit number: 8842.

“Frank, I have the code!” Sarah yelled, moving toward the keypad. “We have to save her!”

“SARAH, WAIT!” Frank roared, stepping in front of her and slamming his arm against the locker to block her path. “Look at the dust on the floor!”

Sarah froze.

The layer of fine concrete dust from the ceiling destruction above had settled evenly across the bunker floor—including right in front of Locker 04. But there were no footsteps coming out of it. There were no feeding trays. No water pipes going in.

“Father died three weeks ago, Sarah,” Frank said, his breath shaking as he stared at the speaker grille on the locker door. “If a human being was locked in there without food or water for three weeks, she’d be dead.”

The sweet, whimpering voice inside the locker instantly stopped.

A long, agonizing silence filled the underground bunker. Then, the voice came back—but it wasn’t a woman’s voice anymore. It was a distorted, multi-layered screech that sounded like grinding metal and agonizing screams synthesized together.

“Clever boy,” the speaker static crackled.

BOOM. Something slammed against the inside of Locker 04 with terrifying, inhuman force. The heavy steel door bulged outward, the welds around the iron deadbolts cracking open like dry ice.

From above the trapdoor, heavy, deliberate footsteps began walking across the broken floorboards of the living room. Someone—or something—was standing right above them.

Frank backed up slowly, pulling Sarah behind him, his eyes locked on the bending steel door of Locker 04 as the red light on the keypad began to flash rapidly. He raised the revolver, squeezed the trigger, and fired directly at the lock.
