The debris was still falling when the second detonation launched a mountain of barrels filled with sulfuric acid into the first extraction facility. Screaming workers fled the interior as the projectiles shredded the ore-leaching vats, releasing a nasty soup of toxic chemicals. Smoke billowed as the doors were flung open and the occupants staggered out.

Juan and Pablo lay in a ditch near the second building, dodging bits of raining debris as they watched a nearby door. At the sound of the explosions, a few curious workers poked their heads outside to investigate. Seeing the smoke and flames from the extraction facility, they called inside to their coworkers, then sprinted to the other building to help. Pablo counted six people rush out before he rose and moved toward the door.

“Stay here and cover me.”

As he reached for the door handle, it twisted from the other side. He jumped back from the opening door as a woman in a lab coat burst out. Her eyes focused on the nearby smoke, she never noticed him behind the door as she nervously followed after her coworkers.

Pablo slipped through the door, stepping into a brightly lit bay filled with dozens more extraction tanks. He turned left and moved to the far end of the building, where large storage tanks lined the wall. He studied their labels, then approached one of the larger tanks. KEROSENE. He tore away a bleed hose from its base, then opened its brass drain valve. A torrent of the liquid flooded across the floor and filled the bay with a gassy odor.

Pablo grabbed a bundle of lab coats from a rack and scurried through the building, stuffing them into all the floor drains. The thin liquid spread quickly, nearly covering the concrete floor. The arsonist made his way back to the door, then pulled a lighter from his pocket. As kerosene trickled past his feet, he leaned down and ignited it, then jumped from the building.

With a low volatility and high flash point, the kerosene didn’t explode, instead igniting in a river of flame. As fire detectors erupted throughout the building, ceiling-mounted sprinklers kicked on—but only for a second, as the disrupted water supply ran dry. Unabated, the fire spread.

Pablo didn’t look back as he ran to his partner in the gully.

Juan looked up and shook his head. “Eduardo says the front gate sentry is on his way.”

Across the grounds, sirens and alarms wailed. But no one had yet noticed the swirl of smoke from the roof of the adjacent building. At three in the morning, no one at the facility was prepared to deal with multiple fires, and municipal firefighters were thirty miles away.
