HE THOUGHT HIS SON WAS A MONSTER TRYING TO KILL HIS LITTLE SISTER—UNTIL HE FOUND THE BLUE SHOEBOX UNDER THE FLOORBOARDS!

The rain pounded down on the corrugated roof of the roundhouse like thousands of drumsticks beating in frenzied unison. Inside, the air was stagnant, thick with the smell of wet soot, rusted iron, and the subtle, rotten-egg stench of sulfurous marsh gas rising from the deep inspection pits beneath the tracks.

Mason sat in the backseat of the Maybach, checking his gold Patek Philippe watch.

11:59 PM.

He leaned forward, tapping the shoulder of his driver—a hulking brute with a shaved head and a scarred neck. “If he’s not through that door in sixty seconds, take the girl into the back room. Use the video camera on the tripod.”

Beside him, Lily was curled into a ball on the leather seat, her face pale, shivering despite the car’s climate control. Her small hands were clasped in front of her chest, whispering silent prayers she had learned in Sunday school.

“Don't bother praying, little bird,” Mason whispered, his voice smooth and cold. “Your father was always a man of small vision. He thought rules mattered. He thought integrity was a shield. Tonight, he learns that the world belongs to men who take what they want.”

Suddenly, with an explosive *CRACK*, the industrial floodlights hanging from the iron rafters died simultaneously.

The entire roundhouse plunged into impenetrable darkness.

The hum of the ventilation blowers beneath the turntable ceased instantly, replaced by the ominous, bubbling hiss of rising gas from the drainage pit.

“What the hell was that?” the driver barked, reaching for his pistol.

Outside the car, the two sentries shouted in confusion, raising their tactical flashlights. The bright white beams cut through the gloom, illuminating swirling clouds of dust and moisture.

*CLANG.*

A heavy metallic sound echoed from the high catwalks forty feet above.

“Catwalk! Twelve o’clock!” one of the sentries shouted, raising his rifle.

Before he could fire, a two-inch steel pipe wrench, dropped from the highest rafter, struck the sentry directly on the crown of his skull. The blow sounded like a bowling ball hitting wet concrete. The guard crumpled to the floor without a sound, his flashlight rolling across the oily tracks.

The second sentry spun around, his weapon sweeping upward, but Daniel was already dropping from the lower maintenance ladder.

Daniel landed on the sentry with the full force of his weight, driving the man into the gravel ballast. The impact knocked the rifle from the guard’s hands. The sentry reached for a combat knife at his belt, but Daniel grabbed the back of the man’s tactical helmet and slammed his face downward into the steel rail track with brutal, unforgiving momentum.

*CRACK.*

The sentry went limp.

Daniel rose, breathing hard, his jacket torn, blood dripping from a scrape across his forehead. He picked up the dropped assault rifle, racked the bolt, and walked toward the Maybach sitting on the central turntable.

The driver’s door of the Maybach flew open. The shaved-head enforcer stepped out, using the car door as cover, leveling an automatic shotgun at Daniel.

“Drop it, Mercer!” the driver snarled. “One move and I turn you into mince—”

*Pfft.*

A rifle round, fired from the high exterior window of the roundhouse, shattered the Maybach’s side mirror and took the driver through the upper shoulder.

The brute screamed, dropping the shotgun, clutching his torn flesh.

Through the high window, fifty yards away, Ethan stood on the rusted fire escape, holding the sentry’s discarded carbine, his hands shaking but his aim true. The boy who had spent years playing simulation games had found his mark when his family needed him most.

“Get away from the car,” Daniel said, his voice deadly calm as he stepped onto the steel turntable.

The rear door of the Maybach clicked open.

Arthur Vance—the man who called himself Mason—stepped out into the dim emergency light. He held a sleek, nickel-plated revolver in his right hand.

With his left, he held six-year-old Lily against his chest, the cold barrel of the gun pressed directly against her temple.

“Daddy!” Lily shrieked, tears streaming down her face.

“Shut up, girl,” Mason hissed, tightening his grip on her collar until she gasped for air.

Mason looked at Daniel, his thin lips curving into a sneer of pure, venomous malice. “You think you’re clever, Daniel? You think killing two hired guns changes the math? I have your daughter. Put the rifle down, or her brains will decorate this windshield before you can blink.”

Daniel didn't drop the rifle.

Instead, he let it fall to his side, hanging loosely from the tactical sling. With his free hand, he reached into his jacket pocket and pulled out the bright red road flare.

He held the flare directly over the circular drainage grate in the center of the turntable.

Mason’s eyes flickered down to the grate. His nostrils flared.

For the first time that night, the smug, arrogant composure on Arthur Vance’s face cracked.

“You smell that, Arthur?” Daniel asked softly. His voice didn't waver. There was no fear in his eyes. Only the cold, absolute certainty of a man who had already accepted his own death. “That’s three hundred cubic meters of pure marsh methane, trapped beneath this steel plate because the blowers were cut two minutes ago.”

Mason swallowed hard, his grip on Lily slipping slightly. “You’re bluffing. You’d incinerate your own daughter.”

“Lily is sitting three feet above the heavy gas line,” Daniel said, his thumb resting on the flare’s friction striker cap. “You and I, however, are standing directly in the combustion zone. If I strike this flare, the fireball will consume us in less than a tenth of a second. My skin will burn, Arthur. But yours will vaporize.”

Daniel looked into the eyes of the man who had terrorized his son and threatened his little girl.
