“Then as I said, I’ll check with my father. But for now…” They shook hands. “Welcome aboard, Professor.”

“Thank you,” Philby replied.

Nina put her pendant back around her neck and placed the artifact on the map of Brazil. She gazed at the blank swath of green surrounding the Tefé river, trying to imagine what she would find there. “So,” she whispered, “that’s where you went…”

ELEVEN

Brazil

Welcome to the jungle!” Chase sang as he exited the plane.

Despite having traveled all around the world, Nina always found arriving in the tropics an unwelcome shock. While she didn’t mind a hot environment per se, it was far easier to adjust to the dry heat of a desert than it was to emerge from an air-conditioned aircraft cabin into the sticky, humid heat of a tropical jungle.

And it was hard to get much deeper into a tropical jungle. Tefé was in the heart of the Amazon basin, the temperature over eighty degrees Fahrenheit and the humidity sticking her clothes to her skin.

But they would be going farther still into the rain forest. Examination of maps, satellite photos and aerial surveys of the region had narrowed down the possible location of the lost city to an area roughly eight miles in diameter, over a hundred miles upriver from Tefé. The nearest permanent settlement was more than thirty miles from the target area, and even that was just a small village. Nina had seen the aerial photographs; they showed nothing but a solid carpet of verdant green, the only thing breaking the monotony being the snakelike twists of rivers.

That same unbroken canopy of jungle had dictated the group’s mode of transport. A helicopter could have reached the area from Tefé in less than ninety minutes-and Kristian Frost had indeed arranged for one to be standing by in case of any emergency requiring a rapid evacuation-but it would have found nowhere to land. People and equipment would need to be winched into the jungle, and Chase, overseeing the logistics of the operation, had decided it was too risky-much to Castille’s relief.

Instead, they would be traveling upriver by boat.

But, Nina thought, it was one hell of a boat.

The expedition would actually be using two boats, but the Nereid was undoubtedly the most important. A Sunseeker Predator 108 motor yacht, the sleek vessel was painted in shades of charcoal gray and silver, the Frost logo prominent on the hull. Nina was astounded to learn that it had been flown to Brazil from Europe in the three days of intense preparation for the expedition, carried to the city of Manaus in the belly of a massive Antonov An-225 transport aircraft and then piloted the three hundred miles upriver to meet its passengers at Tefé. The resources that Kristian Frost was prepared to put behind the search for Atlantis-behind her-staggered her.

Despite its size-from the very tip of its sharply pointed bow to the stern, the Nereid was over a hundred feet long-it was expected to take the expedition quickly and comfortably to within as little as ten miles of their destination, despite the twists and constrictions of the river. The Predator’s shallow draft of less than four feet, and a set of bow and stern maneuvering thrusters enabling it to turn in its own length, meant it could navigate the larger waterways with relative ease.

For those parts of the river the Nereid couldn’t negotiate… that was where the second boat came in. The Nereid’s tender, hanging from a crane at the stern, was a fifteen-foot inflatable Zodiac dinghy. It was the antithesis of its luxurious mother craft, but if everything went to plan it would only be needed for the very last leg of the trip.

The need for a boat the size of the Nereid had come about because the expedition had grown. In addition to Philby, the original team of Nina, Kari, Chase and Castille had been joined by four other people. Two of them comprised the Nereid’s crew: the bearded, rotund Captain Augustine Perez and his “first mate”-the title was used jokingly-Julio Tanega, who smiled frequently and broadly to reveal not one, but two gold teeth.

The third new member was Agnaldo di Salvo, a broad, powerfully built Brazilian in his fifties with the air of a man who was surprised by little and frightened by nothing. Kari had introduced him as their guide to the area, but di Salvo, when Nina asked, called himself an “Indian tracker.” She felt a little too intimidated to ask further about the exact difference between the two. To her surprise, Chase and Castille seemed to know him quite well.

Accompanying di Salvo, and not with his total approval, was another American, a tall, reed-thin graduate student from San Francisco called Hamilton Pendry. He was an environmentalist studying the effects of commercial exploitation of the rain forests on their indigenous population-and was also the nephew of a Democratic congressman, who had persuaded the Brazilian government to let him accompany one of their experts into the jungle. Di Salvo, it seemed, had drawn the short straw. Since the Frosts had specifically requested that di Salvo accompany the expedition, they were now saddled with Hamilton as well, though the exact nature of the mission had been kept from him. Just as well, Nina thought; the long-haired young man seemed genuine in his enthusiasm for the cause of the native Indians and preserving their environment, but God! Shut up about it for five minutes!

Chase had hoped there would be another person joining them, but the reason for her being unable to do so became clear the moment Nina saw her. His friend Maria Chascarillo, when she met them at the dock, turned out to be every bit as beautiful as Shala… and also every bit as pregnant.

“I swear this is just a coincidence!” Chase told the amused Nina and Castille over Maria’s shoulder as they hugged.

“Sure, we believe you,” said Nina. “Don’t we, Hugo?”

“Oh, of course,” Castille replied, munching on a banana.

While Chase was disappointed that Maria wouldn’t be joining the expedition, he was anything but when he opened one of the crates she’d delivered to the dock. Nina couldn’t see the contents, but could guess easily enough. “Guns?” she asked, once Maria had left.

“And some other toys,” he replied cheerfully. “We got caught short in Iran -I’m not going to let that happen again. Besides, from what Agnaldo said about the locals, we might need something to warn them off.”

“What did he say about them?”

“Well, he’s never met them personally-he’s only heard stories. Because people who do meet them… they tend not to come back home to tell anybody about it.”

“What?” Nina shook her head. “No, that sounds like total Indiana Jones stuff. The whole ‘lost tribes of the jungle’ thing doesn’t work anymore. We’re in the twenty-first century.”

“You may be,” said di Salvo from where he had seemingly materialized right behind her. For such a big man he had an uncanny ability to move without being noticed. “But they are not. You think it sounds like a story, but every year dozens of people-loggers, prospectors, even tourists-are murdered by Indian tribes deep in the jungle. It makes my job harder.” He narrowed his eyes and surveyed the dockside, where various people were watching with suspicion. Hardly surprising, Nina realized; compared to the rundown little boats that called the docks home, the gleaming, futuristic form of the Nereid was like a visiting UFO. “These people hate the native Indians, because tribal lands are protected by law-so their livelihoods can be destroyed overnight if a new tribe is found. And it doesn’t help if the Indians are believed to be killing intruders with impunity. So they hate me as well, because it’s my job to find the Indians.”
