"Anyway, as it turns out, Specter never had any intention of dumping the project. His Odyssey engineers have been digging furiously for more than two years. This is borne out by the port we passed, with containerships unloading what was probably mining equipment."
"Wasn't it I who said, 'A neat trick if he could hide millions of tons of excavated rock and muck?'"
"And you were right, it is a neat trick."
A light suddenly flashed on in Giordino's head. "The brown crud?"
"The million-dollar answer," Pitt acknowledged. "Satellite photos never showed construction activity because there was none to be seen. The only way to hide millions of tons of dirt and rock was to build a large tube, mix the muck with water and pump it a couple of miles offshore into the sea."
Giordino opened a Costa Rican beer and wiped the humidity-induced sweat with a towel across his face under the mosquito net. He rolled the cold can across his forehead. "Okay, mister smart guy, why the secrecy? Why would Specter go to such great lengths to cover up the project? Where is the gain if it was created and built to transport goods and materials from sea to shining sea and no one knows it's there?"
Pitt took a beer thrown by Giordino and pulled the tab. "If I knew that, we wouldn't be swimming in our own sweat cruising up the river admiring the wildlife."
"What do we hope to find?"
"An entrance, for one thing. They can't completely hide men and equipment going in and out of the tunnels."
"You think we'll find it on the jungle ride through hell on the African Queen?"
Pitt laughed. "Not on, but under. According to Micky's site plan, the excavation would have run under a town called El Castillo halfway up the river."
"So what's the attraction in El Castillo?"
"Tunnels of extreme length require ventilation shafts to supply air to the workers, cool or heat the air as required and bleed off exhaust fumes from the excavation equipment and smoke in the event of a fire."
Giordino stared uneasily at a huge crocodile swiveling off the bank into the water. Then his gaze turned to the impenetrable jungle along the north bank. "I hope you don't have any plans to hike in there. Mama Giordino's sonny boy would never be seen again."
"El Castillo is an isolated community on the river with no roads in or out. The main attraction is an old Spanish fortress."
"And you think a ventilation shaft pops up where everybody in town can see it," Giordino said dubiously. "Seems to me the jungle is a more ideal hiding place for ventilator shafts. It's so thick no aircraft or satellite photo could spot a shaft from above."
"No doubt most are hidden in the jungle, but I'm counting on them constructing one that comes up near civilization in case they have to use it for an emergency evacuation."
The scenery along the river was so spectacular, the two men drifted off into silence as they absorbed the beauty of the vegetation and the varied species of wildlife. It was like a boating wildlife safari through untouched tropical splendor. They spotted white-faced spider monkeys jabbering at jaguars which lurked under the trees. Anteaters as large as blue-ribbon state fair sows ambled through the brush, keeping a safe distance inshore from the caimans and crocodiles. Colorfully beaked toucans and multihued feathered parrots flew amid rainbows of butterflies and orchids. The jungles around the Rio San Juan had been described by Mark Twain when he journeyed down the river as an earthly paradise, the most enchanted land to be experienced anywhere.
Pitt kept the Greek Angel at a steady and smooth five knots. This was not water to speed through and cause waves from your wake to wash over the environmentally perfect shoreline. The fabulous three thousand acres of virgin rain forest was preserved as the Indio Maiz Biological Reserve. Three hundred species of reptiles, two hundred species of mammals and over six hundred species of birds called it home.
It was four o'clock in the afternoon when they turned off the Rio San Juan onto the Rio Bartola and cruised a short distance before docking at the Refugio Bartola Lodge and Research Center. Nestled in the rain forest, the compound had eleven rooms with private baths and mosquito nets. Pitt and Giordino each registered for a room.
After cleaning up, they headed for the bar and restaurant. Pitt had a tequila on the rocks whose brand was unknown to him. Giordino, claiming he had seen over a dozen Tarzan movies crawling with Engli
shmen on safari, opted for gin. Pitt noticed a fat man in a white suit sitting by himself at a table near the bar. There was an air about the man that suggested he was a respected local resident of the river, someone who might be a wealth of information.
Pitt approached the man. "Pardon me, sir, but I wondered if you might like to join my friend and me."
The man looked up and Pitt could see he was quite elderly, approaching his eighties. His face was flushed and he sweated freely, but miraculously managed not to stain his white suit. He wiped a handkerchief over his bald head and nodded. "Of course, of course, I'm Percy Rathbone. Please, it might be easier if you joined me," he said, pointing at his girth that amply filled his wicker chair.
"My name is Dirk Pitt and my friend here is Al Giordino."
The handshake was firm but sweaty. "Pleased to meet you. Sit down, sit down."
Pitt was amused that Rathbone had a habit of repeating his words. "You have the look of a man who knows and enjoys the jungle."
"It shows, it shows, does it?" said Rathbone, with a short laugh. "Lived along the river in Nicaragua and Costa Rica most all my life. My family came here during World War Two. My father was an agent for the British, keeping an eye on Germans who tried to operate hidden facilities in the lagoons to service and refuel their U-boats."
"If I may ask, how does someone earn a living on a river in the middle of nowhere?"
Rathbone looked at Pitt slyly. "Would you, would you believe I rely on tourism?"
