The eighty-year-old woman slapped the hospital director before anyone understood why.

"Nathan!" Dr. Thorne roared, slamming his fists against the reinforced glass window of the steel door. "You are out of your mind! There are federal monitors auditing this facility's records every quarter! You can't cover this up!"

"I don't need to cover it up forever, Aris," Nathan Cole said smoothly through the speaker. He adjusted his dark tie, his eyes cold and devoid of remorse. "I only need four hours. By the time the morning shift arrives, a fire in the sub-basement electrical housing will have destroyed these old archives completely. Smoke inhalation is a tragic risk in old facilities like this."

Laura shrieked, pulling Sophie closer to her chest. "He's going to burn us alive!"

"Nathan, listen to me!" Dr. Thorne yelled, his palms pressed against the glass. "There's an infant in here! A newborn child!"

"The infant will be recovered by my team before the suppression systems activate," Nathan replied calmly. "She will be safely delivered to her designated private transport. As for you, Mrs. Carter, and your daughter... your tragic history of mental instability will finally reach its logical, tragic end."

Nathan nodded to the three tactical guards beside him. One of them pulled a heavy steel bar from a duffel bag and jammed it through the handles of the double exterior doors leading into the archive corridor, sealing the entire section off from the rest of the hospital.

Inside the room, the ventilation ducts above their heads suddenly clicked off. A faint, sweetish odor began to drift down from the ceiling vents.

"Halon gas," Dr. Thorne spat, turning around instantly. "He’s triggered the fire suppression system manually to purge the oxygen from the room!"

Evelyn didn't panic. She didn't scream.

In her eighty years on Earth, Evelyn Carter had learned one fundamental truth: panicking gave the enemy time.

She turned her sharp eyes around the dark vault, scanning the metal shelving, the heavy oak desk, and the concrete walls.

"Thorne," Evelyn said, her voice like steel. "Where does that air shaft lead?" She pointed to an old, rectangular metal grate near the floor in the back corner of the room.

"It’s an abandoned service duct from the 1970s," Thorne said, coughing slightly as the air in the room began to thin. "It leads to the old boiler room behind the laundry facility. But it’s screwed tight into the masonry!"

"Hand me that heavy paper weight," Evelyn ordered, pointing to a thick brass block on the desk.

Thorne grabbed the brass weight and handed it to her. Evelyn didn't hesitate. Despite her age, she dropped to her knees on the concrete floor, raised the brass block with both hands, and slammed it repeatedly against the rusted screws of the iron grate.

BANG! BANG! BANG!

The third strike shattered the corroded iron frame. The grate fell inward with a loud metallic crash, revealing a dark, dusty tunnel wide enough for a person to crawl through.

"Laura," Evelyn commanded, pulling herself up and grabbing her daughter’s wheelchair handles. "Get down. We’re moving."

"Mom, I can't climb through that!" Laura sobbed, clutching her belly as another contraction-like pain swept through her abdomen. "My C-section..."

"You can and you will, Laura Carter!" Evelyn said, her eyes burning with fierce, unstoppable maternal authority. "You survived Richard Cole twenty-eight years ago! You are going to pull yourself through that duct and save your daughter today! Now give Sophie to Dr. Thorne!"

Dr. Thorne carefully took the swaddled baby, wrapping her inside his thick tweed coat to protect her from the dust. "I’ll go first to clear the cobwebs and lead the way. Laura, crawl right behind me. Keep your head low. Mrs. Carter, you come last."

"No," Evelyn said, pushing Laura toward the opening. "Go! Now!"

The air in the room was growing heavy. The oxygen levels were dropping fast. Laura, gritting her teeth against the blinding white agony in her stomach, lowered herself to the floor. Guided by the pure instinct to protect her child, she squeezed into the narrow metallic tunnel behind Dr. Thorne.

Evelyn looked back at the glass window one last time.

Through the thick pane, she saw Nathan Cole standing in the corridor, looking at his watch, waiting for them to lose consciousness.

Evelyn lifted her hand, placed her palm against the glass, and gave him a cold, mocking smile. Then she turned, dropped onto her knees, and pulled herself into the dark service tunnel, shoving the heavy brass desk weight into the opening behind her to block any pursuers.

The tunnel was narrow, cold, and smelled of decades of dried lime and coal dust.

Dr. Thorne moved steadily ahead, using his smartphone flashlight to illuminate the metal walls. Behind him, Laura crawled inch by inch, groaning through her teeth every time her knees pulled against her fresh surgical stitches.

"Keep going, baby," Evelyn’s voice echoed from behind her in the dark. "Don't look back. Keep moving toward the light."

"It hurts, Mom..." Laura wept, her forehead pressed against the cold metal floor of the duct. "I can't..."

"You can!" Evelyn yelled, her voice filled with twenty-eight years of stored strength. "Think about Sophie’s face! Think about her holding your finger! You are her mother, Laura! A mother does not stop!"

With a raw, primal scream, Laura dug her elbows into the metal floor and dragged herself forward another five feet.

Ahead of them, a bright square of yellow light appeared.

Dr. Thorne reached the end of the duct, slammed his shoulder against the rusted exterior hatch, and burst through into the warm, steam-filled air of the main laundry facility.

He scrambled out onto the tile floor, quickly turning back to pull Laura out by her arms. Evelyn emerged right behind them, her face covered in gray dust, her hands scraped and bleeding, but her eyes burning as bright as suns.

"We’re out," Thorne panted, checking baby Sophie beneath his coat. The baby let out a sharp, healthy cry—her tiny lungs full of fresh air.

"Where is Nathan going now?" Evelyn asked, wiping dust from her face with her sleeve.

Thorne checked his phone as a series of urgent internal emergency alerts began flashing on his screen. "He’s triggering a fake medical emergency evacuation on the fourth floor. He’s going to use the confusion to bring in his fake transport team and claim Sophie was lost in the chaos!"

Evelyn reached into Thorne’s coat pocket, pulled out his master keycard, and turned toward the service elevator near the laundry bin.

"Mom, where are you going?!" Laura cried, resting against a laundry cart.
