The heavily loaded trucks moved slowly down the rough road until they reached the main highway, then they rolled south through the dusty town that was built by the mining operation. Leaving behind that small bastion of civilization, they drove across the same barren steppes of Inner Mongolia that Genghis Khan had conquered eight centuries earlier. Zhou figured they would off-load their cargo at the nearest railroad depot. When they reached the populous city of Baotou several hours later and turned east, he knew otherwise.

The convoy rolled onto the busy Jingzhang Expressway, which ran to Beijing. Outside of the capital city, they paused at a truck stop in the suburb of Changping as dusk was settling. A light wind had picked up, blowing swirls of sand from the Gobi Desert. Zhou wrapped his face with a scarf he found in Jiang’s coat pocket and stretched his legs away from the others while the trucks were refueled.

The trucks moved off slowly, fighting their way through the thickening city traffic. They looped around the west side of Beijing to avoid the worst of the congestion and continued southeast. It took the better part of two hours before they reached the port city of Tianjin. Xao led the trucks through a maze of streets to the center of the large commercial docks.

They reached an old dockside warehouse and pulled down a side alley. Two men appeared from the shadows and accepted a sack filled with yuan that Xao passed out the window. A gate opened at the end of the alley, and the trucks rumbled through, entering a cavernous warehouse that opened to a dock on the far side. The trucks drove through the building and stopped beside a moderate-sized freighter whose lights illuminated the pier.

A large conveyor system stretched from the dock to an open hold on the ship, and Xao backed his truck to the end of it. A work crew appeared with shovels and began emptying the truck’s load of ore. As Zhou watched from the end of the line, he realized he’d seen all he needed. He slipped out the passenger door and crept toward the back of the truck.

A deck officer from the freighter, who was standing on the dock checking the ship’s lines, glanced over at Zhou. Playing the part of a tired driver, Zhou stretched his arms and yawned as he stepped toward the officer.

“Good evening,” he said with a slight bow. “A fine ship you have here.”

“The Graz is old and tired, but she still plows through the sea like a hefty ox.”

“Where are you headed?”

“We do a cargo swap in Shanghai, then we’re off to Singapore.”

He looked at Zhou closely under the lights, noticing a damp streak of red on the sleeve of his jacket.

“Are you okay?”

Zhou glanced at the blood and grinned.

“It’s transmission fluid. I spilled it, adding some to the truck.”
