Trojan Odyssey (Dirk Pitt 17)

"Later," replied Pitt. "Let's push ahead and follow the muck on the conveyor belt."

Giordino was stunned at the power of the golf cart. He got it up to fifty miles an hour and he soon began overhauling other vehicles on the concrete road.

"Better slow down," cautioned Pitt. "We don't want to arouse suspicion."

"You think they got traffic cops down here?"

"No, but big brother is watching," Pitt countered, discreetly nodding at a camera mounted above on the overhead lighting system.

Giordino reluctantly slowed and settled behind a bus traveling in the same direction. Pitt began timing the bus schedule and quickly calculated that the buses ran twenty minutes apart and stopped at work sites when and wherever miners waited to board or requested to get off. He glanced at the hands on his watch. It was only a question of time before the technicians on the replacement shift entered the ventilator control room and found their coworkers duct-taped to the floor. So far, no alarms had been sounded, nor had they seen security guards cruising up and down the tunnel as if searching for someone.

"We're coming up on something," Giordino alerted Pitt.

A thumping sound became stronger as they moved closer to what Pitt quickly identified as a giant pumping station. The rock that had been crushed to sand was sent from the conveyor belt into a monstrous bin. From there, pumps the size of a three-story building thrust it into huge pipes. As Pitt had concluded, the contaminated muck was then propelled into the sea where Poco Bonito had run aground on the accumulation. Beyond the pumping stations were giant steel doors.

"The enigma goes deeper," said Pitt thoughtfully. "Those pumps are monumental, far more capable of pumping ten times the excavated muck. They must serve another purpose."

"They'll probably dismantle them when the tunnel is finished."

"I don't think so. They look permanent."

"I wonder what's on the other side of those doors," said Giordino.

"The Caribbean," answered Pitt. "We must be miles from shore and deep beneath the surface of the sea."

Giordino's eyes never left the doors. "How in the world did they dig this thing?"

"They began with an open excavation onshore by digging a portal. First, a starter tunnel was launched with a different type of machine called a roadheader excavator. When it reached a calculated depth, the big boring machine was brought in and assembled in the excavated tunnel. It worked east under the sea, then it must have been disassembled and reassembled so it could begin excavating in the opposite direction toward the west."

"How could an operation this size be kept secret?"

"By paying the miners and engineers big bucks to keep their mouths shut, or perhaps by threats and blackmail."

"According to Rathbone, they don't hesitate to kill intruders. Why not workmen with loose tongues?"

"Don't remind me about intruders. Anyway, suspicions confirmed," Pitt said slowly. "The brown crud is spread into the sea by man without the slightest consideration for the terrible consequences."

Giordino shook his head slowly. "A contaminated dump operation that puts all others to shame."

Pitt reached into his knapsack again and lifted out a small digital camera and began taking pictures of the giant pumping operation.

"I don't suppose your magical kit can produce any food and drink?" probed Giordino.

Pitt reached inside and produced a pair of granola bars. "Sorry, that's the best I can do."

"What else is in there?"

"My trusty old Colt forty-five."

"I guess we can always shoot ourselves before they hang us," Giordino said glumly.

"We've seen what we came for," said Pitt. "Time to go home."

Giordino was pressing his foot on the accelerator before Pitt finished his sentence. "The sooner we're out of here, the better. We're on borrowed time as it is."

Pitt continued snapping pictures as they drove. "One more detour, I want to see what's inside those crosscut tunnels."

As he accelerated, Giordino sensed that heading off into a side tunnel was only part of Pitt's plan. He was dead certain that Pitt wanted to check out the other end of the tunnel and observe the big boring machine in action. Pictures were taken of every piece of equipment they passed. No small detail of the tunnel's construction went unrecorded.
