“Or like in Gerald Clark?” Kouwe eyed her. “You’re suggesting something turned off his immune system so he was able to regenerate his arm, but this phenomenon also allowed multiple cancers to sprout throughout his body.”
“Perhaps. But it has to be more complicated than that. What’s the mechanism? Why did all the cancers arise so suddenly?” She shook her head. “And more important, what could trigger such a change?”
Kouwe nodded toward the dark jungle. “If such a trigger exists, it might be found out there. Currently three-quarters of all anticancer drugs in use today are derived from rain forest plants. So why not one plant that does the opposite—one that causes cancer?”
“A carcinogen?”
“Yes, but one with beneficial side effects…like regeneration.”
“It seems improbable, but considering Agent Clark’s state, anything might be possible. Over the next few days, at my request, the MEDEA researchers will be investigating the status of Gerald Clark’s immune system and examining his cancers more closely. Maybe they’ll come up with something.”
Kouwe blew out a long stream of smoke. “Whatever the ultimate answer is, it won’t come from a lab. Of that I’m certain.”
“Then from where?”
Instead of answering, Kouwe simply pointed the glowing bowl of his pipe toward the dark forest.
Hours later, deeper in the forest, the naked figure crouched motionless in the murk of the jungle, just beyond the reach of the firelight. His slender body had been painted with a mix of ash and meh-nu fruit, staining his skin in a complex pattern of blues and blacks, turning him into a living shadow.
Ever since first dark, he had been spying upon these outsiders. Patience had been taught to him by the jungle. All teshari-rin, tribal trackers, knew success depended less on one’s actions than on the silence between one’s steps.
He maintained his post throughout the night, a dark sentinel upon the camp. As he crouched, he studied the giant men, stinking with their foreignness, while they circled around and around the site. They spoke in strange tongues and bore clothing most odd.
Still, he watched, spying, learning of his enemy.
At one point, a cricket crawled across the back of his hand as his palm rested in the dirt. One eye watched the camp, while the other watched the small insect scratch its hind legs together, a whisper of characteristic cricket song.
A promise of dawn.
He dared wait no longer. He had learned all he could. He rose smoothly to his feet, the motion so swift and silent that the cricket remained on the back of his steady hand, still playing its last song of the night. He raised the hand to his lips and blew the surprised insect from its perch.
With a final glance to the camp, he fled away into the jungle. He had been trained to run the forest paths without disturbing a single leaf. None would know he had passed.
Moreover, the tracker knew his ultimate duty.
Death must come to all but the Chosen.

The Amazon Factor
AUGUST 11, 3:12 P.M.
AMAZON JUNGLE
Nate kept one finger fixed to his shotgun’s trigger, the muzzle pointed ahead. The caiman had to be almost twenty feet long. It was a huge specimen of Melanosuchus niger, the black caiman, the king of the giant crocodilian predators of the Amazon rivers. It lay atop the muddy bank, sunning in the midafternoon heat. Black armored scales shone dully. Its maw gaped slightly open. Jagged yellow teeth, longer than Nate’s own palm, lined the cavity. Its bulging, ridged eyes were solid black, cold and dead, the eyes of a prehistoric monster. Stone still, it was impossible to tell if the great beast even acknowledged the trio of approaching boats.
“Will it attack?” Kelly whispered behind him.
Nate shrugged without looking back. “They’re unpredictable. But if we leave it alone, it should leave us alone.”
Nate crouched in the prow of the middle pontoon boat. He shared the craft with the two O’Briens, Richard Zane, and Anna Fong. A single soldier, Corporal Okamoto, manned the small outboard engine in the boat’s stern. The stocky Asian corporal had developed the habit of whistling almost nonstop, which after four days of motoring up the wide tributary had grown to be excruciating. But at least the giant monster lounging on the bank had squelched the man’s tuneless noise.
Ahead, the lead boat puttered past the beast, sticking close to the opposite shore. The starboard pontoon bristled with M-16s, all pointing toward the black caiman.
Each boat held a complement of six team members. The lead boat carried three soldiers and the rest of the civilians: Professor Kouwe, Olin Pasternak, and Manny, who lounged with his pet jaguar in the center of the boat. Tor-tor had been on boats before and seemed to enjoy this means of transportation, tail lazily flicking, ears pricked for noises, eyes mostly in a half-lidded drowse.
The rear boat held the other six Rangers, anchored by Captain Waxman.
“They should just shoot the damn thing,” Frank said.
Nate glanced to the man. “It’s an endangered species. In the last century, they were poached to near extinction. Only lately have their numbers grown.”
“And why does this news not please me?” Frank muttered, glancing to the waters around them. He tugged the bill of his baseball cap lower as if he were trying to hide behind it.
“The caimans kill hundreds every year,” Zane mumbled, hunched down beside his pontoon. “They’ve swamped boats, attacking anything. I read about a black caiman found dead with two outboard motors in its belly, swallowed whole. I’m with Mr. O’Brien. A few well-placed shots…”
By now, the lead boat was past the beast’s sunning spot, and Nate’s boat followed next, moving slowly against the sludgy current as it passed the caiman, motor rumbling.
“Marvelous,” Nate said. He faced the creature, no farther away than thirty yards. It was monstrous, a creature from another time. “It’s bloody beautiful.”
“A male, isn’t it?” Anna Fong asked, staring avidly.
“From the ridge lines and shape of the nostrils, I’d agree.”
“Shh!” Frank hissed at them.
“It’s moving!” Kelly yelped, shifting from her seat to the far side of the boat. She was quickly followed by Richard Zane.
The armored head swung slowly, now following their boat.
“It’s waking up,” Frank said.
“It was never asleep,” Nate corrected as they glided safely past. “It’s just as curious about us as we are about it.”
