Nathan glanced to Kelly, who stared at her toes.

Frank simply nodded. "He's right. But even at Tellux, only a handful of people know the true purpose of our mission here:"

Nate shook his head. "Great, just great:" Kouwe placed a sympathetic hand on his shoulder.

"All that aside," Manny said, "what's our first step?"

"Let me show you:" Kelly turned once again to the maps on the back wall. She pointed to the centermost one. "I'm sure Dr. Rand is familiar with this map:"

He stared at it and did indeed recognize it like the lines on his own palm. "It's the recorded route my father's team took four years ago:"

"Exactly;" Kelly said, tracing her finger along the dotted course that led in haphazard fashion from Manaus south along the Madeira River until it reached the town of PBrto Velho, where it angled north into the heart of the Amazon basin. From there, the team crisscrossed the area until they bridged into the little-explored region between the southern and northern tributaries of the Amazon. Her finger stopped at the small cross at the end

of the line. "Here is where all radio contact with the team ceased. And where all searches originated-both those sponsored by the Brazilian government and those financed privately" She glanced significantly at Na-than. "What can you tell us about the searches?"

Nate circled around the desk to stare at the map. A familiar creeping despair edged through the core of his being. "It was December, the height of the rainy season," he whispered dully. "Two major storm systems had moved through the region. It was one of the reasons no one was initially concerned. But when an update from the team grew to be almost a week late and the storms had abated, an alarm went up. At first, no one was really that worried. These were people who had lived their lives in the jungle. What could go wrong? But as search teams began tentatively looking, it was realized that all trace of the expedition was gone, erased by the rains and the flooded forests. This spot"-Nathan placed a finger on the black X-"was found to be underwater when the first team arrived."

He turned to the others. "Another week went by, then another. Nothing. No clues, no further word . . . until one last frantic signal. `Send help . . . can't last much longer. Oh, God, they're all around us: "Nate took a deep breath. The memory of those words still haunted him deeply. "The signal was so full of static that it was impossible to discern who even spoke. Maybe it was this Agent Clark:" But in his heart, Nathan knew it had been his father. He had listened over and over to that last message. The last words of his father.

Nathan stared at the photos and documents strewn across the desktop. "For the next three months, the searchers swept throughout the region, but storms and floods made any progress difficult. There was no telling in which direction my father's team had headed: east, west, north, south:" He shrugged. "It was impossible. We were searching a region larger than the state of Texas. Eventually everyone gave up:"

"Except you;" Kelly said softly.

Nathan clenched a fist. "And a lot of good that did. No further contact was ever heard:"

"Until now," Kelly said. She gently drew him around and pointed to a small red circle he had not noticed before. She pointed to it. It lay about two hundred miles due south of Sao Gabriel, near the river of Jarura, a

branch of the Solimoes, the mighty southern tributary of the Amazon. "This is the mission of Wauwai, where Agent Clark died. This is where we're heading tomorrow."

"And what then?" Manny asked.

"We follow Gerald Clark's trail. Unlike the earlier searches, we have an advantage:"

"What is that?" Manny asked.

Nathan spoke up, leaning close to the wall map. "We're at the end of the dry season. There hasn't been a major storm through here in a month:" He glanced over his shoulder. "We should be able to track his movements."

"Hence, the urgency and speed of organizing this mission:" Frank stood. He leaned one hand on the wall and nodded to the map. "We hope to follow any clues before the wet season begins and the trail is washed away. We're also hoping Agent Clark was sound enough in mind to leave some evidence of his route-marks on a tree, piles of rock-some way to lead us back to where he had been held these past four years:"

Frank turned back to the desk and slid out a large folded sheet of sketch paper. "In addition, we've employed Anna Fong so we can communicate with any natives of the region: peasants, Indians, trappers, whoever. To see if anyone has seen a man with these markings pass by" Frank unfolded and smoothed the paper. A hand-sketched drawing was revealed. "This was tattooed across Agent Clark's chest and abdomen. We hope that we'll find isolated folk who might have seen a man with this marking:"

Professor Kouwe flinched.

His reaction did not go unnoticed by those in the room.

"What is it?" Nathan asked.

Kouwe pointed to the sketch paper. It delineated a complex serpentine pattern that spiraled out from a single stylized handprint.

"This is bad. Very bad:' Kouwe fumbled in his pocket and pulled out his pipe. He lifted a questioning eye at Frank.

The redheaded man nodded.

Kouwe slipped out a pouch and tamped some locally grown tobacco into the pipe, then lit it with a single match. Nathan noted his uncharacteristically trembling fingers.

"What is it?"

Kouwe puffed on his pipe and spoke slowly. "It's the symbol for the Ban-all. The Blood Jaguars:"

"You know this tribe?" Kelly asked.

The shaman blew out a long stream of smoke and sighed, then shook his head. "No one knows this tribe. It is what's whispered among village elders, stories passed from one generation to another. Myths of a tribe that mates with jaguars and whose members can vanish into thin air. They bring death to all who encounter them. It is said they are as old as the forest and that the very jungle bends to their will:"

"But I've never heard of them;" Nathan said, "and I've worked with tribes throughout the Amazon:"

"And Dr. Fong, the Tellux anthropologist," Frank said. "She didn't recognize it either."

"I'm not surprised. No matter how well you're accepted, a non-tribesman will always be considered pananakiri, an alien to the Indians of the region. They would never speak of the Ban-ali to you:"

Nate couldn't help but feel a bit insulted. "But I-"

"No, Nathan. I don't mean to slight your own work or abilities. But for many tribes, names have power. Few will speak the name Ban-ali. They fear to draw the attention of the Blood Jaguars:" Kouwe pointed to the drawing. "If you take this symbol with you, it must be shown with care. Many Indians would slay you for possessing such a paper. There is no greater taboo than allowing that symbol into a village:"

Kelly frowned. "Then it's doubtful Agent Clark passed through any villages:"

"If he did, he wouldn't have walked out alive:"

Kelly and Frank shared a concerned look, then the doctor turned to Nathan. "Your father's expedition was cataloging Amazonian tribes. If he had heard of these mysterious Ban-ali or had found some clue of their existence, perhaps he sought them out:'

Manny folded the sketched drawing. "And perhaps he found them:"

Kouwe studied the glowing tip of his pipe. "Pray to God he did not:"
