They arose and put on light backpacks. Lights from the mine buildings were sprinkled across the hillside in front of them, casting a pale glow over the barren desert. They hiked a short distance to a chain-link fence that encircled the complex. The taller man knelt and rummaged through his pack for a pair of wire cutters.

“Pablo, I think we can get through without cutting,” his partner whispered, then pointed to a dry wash that ran beneath the fence.

The sandy ground was soft in the middle of the creek bed, and he easily pushed some of it aside with his foot. Pablo joined him in scraping away the loose soil until they had excavated a small hole beneath the fence. Pushing their packs under it, they quickly shimmied through.

A low blend of rumbling noises filled the air, the mechanical bedlam of an open-pit mine that operated around the clock. The two men stayed clear of the guard station, to their right, and made their way up a gentle slope toward the mine itself. A ten-minute hike brought them to a cluster of aged buildings crisscrossed with large conveyor belts. A front-end loader at the far end was shoveling piles of ore onto one of the moving belts, which transported it to a hopper on stilts.

The two men were headed to a second cluster of buildings farther up the hill. The mine pit blocked their way, forcing them to cut through the operations area, where ore was crushed and milled. Clinging to the shadows, they darted along the perimeter, then worked their way along the back of a large storage building. Reaching an exposed area between buildings, they moved quickly, striding past a semiburied bunker to their left. Suddenly a door flung open at the center of the building ahead of them. The two men split up, Juan ducking to the side and scrambling behind the bunker while Pablo sprinted ahead toward the side of the building.

He didn’t make it.

A bright yellow beam snapped on, blinding him.

“Hold it right there or you’ll regret taking that next step,” said a low, gravely voice.

Pablo stopped in midstride. But as he made an exaggerated stop, he deftly withdrew a mini automatic pistol from his left hip and concealed it in the palm of his gloved hand.

The overweight security guard walked slowly toward him, keeping his flashlight pointed into Pablo’s eyes. The guard could see the intruder was a large, well-proportioned man, over six feet tall. His coffee-colored skin was smooth and pliant, in contrast to black eyes that burned with malignant intensity. A lighter band of flesh crossed his chin and left jaw, the souvenir from an ancient knife fight.

The guard saw enough to know he wasn’t an accidental trespasser and stopped a healthy distance away, clutching a .357 Magnum.

“How about you put your hands on your head and then you can tell me where your friend went.”
