But now all that was left of his parents' legacy was gone, dismantled and swallowed by Tellux.

"Looks like we're getting an escort," Manny said, breaking through Nate's thoughts.

At the gate's guard station, two Rangers in tan berets stood stiffly behind a nervous-looking Brazilian soldier.

Nathan eyed their holstered sidearms warily and wondered again at the nature of this meeting.

As they reached the gates, the Brazilian guard checked their identifications. Then one of the two Rangers stepped forward. "We're to take you to the debriefing. If you'll please follow:" He turned sharply on his heel and strode away.

Nathan glanced to his friends, then proceeded through the gates. The second Ranger took up a strategic position behind them. Ushered along by their escorts, with a view of the four military helicopters resting on the camp's soccer field, Nathan felt a distinct sense of dread in his belly.

None of this seemed to concern Professor Kouwe. He simply puffed on his pipe and strode casually after their armed escort. Manny also appeared more distracted than alarmed.

They were marched past the corrugated Quonset buts that served as barracks for the Brazilian troops and led to a derelict timber-framed ware-house on the far side with the few windows painted black.

The Ranger in the lead opened the rusted door. Nathan was the first through. Expecting to find a gloomy, spider-infested interior, he was surprised to find the large warehouse brightly lit with halogen poles and over-head fluorescents, The cement floor was crisscrossed with cables, some as thick around as his wrist. From one of the three offices lining the back half of the warehouse, a generator could be heard chugging away.

Nathan gaped at the level of sophisticated hardware positioned throughout the room: computers, radio equipment, televisions, and monitors.

Amid all the organized chaos, a long conference table had been set up, strewn with printouts, maps, graphs, even a pile of newspapers. Men and women in both military garb and civilian clothes were busy throughout the room. Several were poring over reams of paper at the table, including Kelly O'Brien.

What's going on here? Nathan wondered.

"I'm afraid there's no smoking inside," their escort said to Professor Kouwe, indicating the lit pipe.

"Of course:" Kouwe tapped out his pipe's bowl onto the threshold's dirt floor. The Ranger used his boot heel to squash the burning tobacco. "Thank you:"

From across the way, one of the office doors opened and the tall red-headed man who appeared to be Dr. O'Brien's brother stepped out. At his side was a man Nate knew well enough to dislike immensely. He was dressed in a navy blue suit with the jacket slung over one arm, a coat Nate was sure bore the Tellux logo. As usual, his dark brown hair was oiled and combed into perfect place, as was his smartly trimmed goatee. The smile he wore as he approached Nathan and his two friends was just as oily.

On the other hand, his redheaded companion crossed with an arm extended and a more genuine expression of welcome. "Dr. Rand, thank you for coming. I think you know Dr. Richard Zane."

"We've met," Nathan said coldly, then shook the redhead's hand. The man had a grip that could crush stone.

"I'm Frank O'Brien, the head of operations here. You've already met my sister." He nodded over to Kelly, who glanced up from the table. She lifted a hand in greeting. "Now that you're all here we can get this meeting under way."

Frank guided Nate, Kouwe, and Manny toward the table, then waved an arm, signaling the others to take their seats.

A hard-faced man with a long pale scar across his throat settled him-self across the table from Nathan. At his side sat one of the Rangers, his two silver bars suggesting he was the captain of the military forces here.

At the head of the table, Richard Zane sat between Kelly and Frank, who remained standing. To the left was another Tellux employee, a small Asian woman in a conservative blue pantsuit. Her eyes glinted with intelligence and seemed to soak in everything around her. Nate caught her gaze. She gave him the faintest of smiles and nodded her head.

Once everyone else was settled, Frank cleared his throat. "First, Dr. Rand, let me welcome you to the command center for Operation Amazonia, a joint operation between the CIA's Environmental Center and Special Forces Command:" He gave a short nod to the silver-barred captain. "We're also supported by the Brazilian government and are assisted by Tellux Pharmaceutical's research division."

Kelly interrupted her brother, raising a hand. She clearly read the con-fusion on Nathan's face. "Dr. Rand, I'm sure you've many questions. Fore-most being, why you've been sought as a partner in this venture:"

Nathan nodded.

Kelly stood. "The main objective of Operation Amazonia is to discover the fate of your father's lost expedition."

Nate's jaw dropped and his vision blackened at the edges. He felt as it he'd just been sucker-punched. He stammered for half a moment until he found his voice. "But. . . but that was over four years ago:"

"We understand that, but-"

"No!" He found himself on his feet, his chair skittering across the cement behind him. "They're dead. All dead!"

Professor Kouwe reached to place a restraining hand on his elbow. "Nathan. . :"

He shook his arm free. He remembered that call as if it were yesterday. He had been finishing up his doctoral thesis at Harvard. He had taken the next plane down to Brazil and joined the search for the vanished team. Memories flowed through him as he stood in the warehouse-the blinding fear, the anger, the frustration. After the searches were called off, he had refused to give up. He couldn't! He had pleaded with Tellux Pharmaceuticals to help continue the search privately. Tellux had been a co-sponsor, along with Eco-tek, in this venture. The ten-year goal: to conduct a census of the current populations of indigenous tribes and begin a systematic cataloging of their medicinal knowledge before such information was lost forever. But Tellux had refused Nate's request for assistance. The corporation had supported the conclusion that the team either had been killed by a tribe of hostile Indians or had stumbled upon a camp of drug traffickers.

Nate had not. Over the next year, he spent millions continuing the search, beating the bush for any sign, clue, inkling of what had become of his father. It was a financial black hole into which he poured Eco-tek's assets, further destabilizing his father's company. Eco-tek had already taken a devastating hit on Wall Street, its stock value plummeting after the loss of its CEO in the jungle. Eventually, the well ran dry. Tellux made a run for his father's company in a hostile takeover bid. Nate was too wounded, tired, and heartsore to fight. Eco-tek and its assets, including Nathan himself, became beholden to the multinational corporation.

What followed was an even blacker period of his life, a hazy blur of alcohol, drugs, and disillusionment. It was only with the help of friends like Professor Kouwe and Manny Azevedo that he had ever found himself again. In the jungles, he found the pain was less severe. He discovered he could survive a day, then another. He plodded his way as best he could, continuing his father's work with the Indians, financed on a pittance from Tellux.

Until now. "They're dead!" he repeated, sagging toward the table. "After so long, there's no hope of ever discovering what happened to my father:"

Nathan felt Kelly's penetrating emerald eyes on him as she waited for him to compose himself. Finally, she spoke. "Do you know Gerald Wallace Clark?"
