FISHEReased the strap off his shoulder, shifted the M-14 to his right, and then stopped on the trail and gave Jimiyu a soft tsst. On either side of Fisher the jungle was a thick wall of green. He sat down on his haunches. Jimiyu, walking ten feet ahead, stopped and looked over his shoulder. Fisher curled a finger at him, and he walked back.

"We're being followed," Fisher said.

"Yes, I assumed so," Jimiyu replied. "We're on the border between the Samburu and Turkana tribes. Do not worry; they are simply curious. We are not one or the other tribe, so our presence should not upset them." Jimiyu smiled and placed a hand on Fisher's shoulder.

"Is that a hard-and-fast rule?"

Jimiyu shrugged. "I see the jungle is not foreign to you."

More like an old friend,Fisher thought.

"Perhaps you are Samburu or Turkana," the Kenyan said. "How did you know?"

"Because there's a pair of eyes watching us. Ten feet to your left."

Very slowly, Jimiyu rotated his head to the left and scanned the foliage. As Fisher had said, a pair of white-rimmed brown eyes were peering at them from behind a palm trunk.

"Turkana," Jimiyu whispered. He raised a hand to chest level, palm out and said, "Hujambo?"Which means: How do you do?

The figure ducked out of sight and a few seconds later soundlessly emerged from the jungle ten feet down the trail. The man was wearing denim shorts and a faded red T-shirt bearing the words THE CLASH ANARCHY TOUR 1976. A butcher knife with a rope-wrapped handle jutted from the front belt loop on his shorts.

"Jambo,"he said.

Jimiyu stood up and walked forward. The men shook hands and began speaking in rapid-fire Swahili. Most Kenyan tribes, Fisher had learned, speak at least two languages--Swahili and their own native dialect, of which there are more than thirty--and many speak a modicum of English. Jimiyu and the man spoke for another few minutes, then shook hands again, and the man stepped off the trail and disappeared.

"What's the verdict?" Fisher asked.

"He's Turkana; they and the Samburu have already talked about our presence. As long as we do not hunt here, we have safe passage."

"He didn't want to know why we're here?"

"I told him you were a . . ." Jimiyu paused and scratched his head. "The word does not translate so well. I told him you were a spoiled white adventurer."

Fisher laughed, and Jimiyu gave a pained shrug. "Apologies. It was a convenience on my part. Better that than try to explain. I also asked about the plane. Both tribes are aware of the legend, but neither have seen any sign of it."

THEYwalked for another three hours, sometimes on well-worn paths, sometimes on narrow game trails, and other times through the thick of the jungle Fisher navigated via his GPS unit. The purist orienteer in him resented the gizmo, but the pragmatist in him knew it was a necessary evil. With limited time on his hands, a compass was a luxury he couldn't afford.

Jimiyu, armed with a long Ghurka knife, sliced his way through the foliage with practiced swings of his long arms, ducking and weaving like a boxer as he stepped over roots and ducked under branches and pointed out various plants and animals beside the trail along with a running, colorful commentary: "Very rare . . . do not touch that . . . not poisonous . . . tasty, but hard to catch . . ."

At noon they swung back to the northeast, and after another hour's walk Fisher heard the muffled roar of water through the trees. The landscape sloped downward until they were picking their way along switchbacked hillside. At last the slope evened out, the trees gave way to low scrub foliage, and they found themselves standing at the edge of a cliff.

Fifty feet below, the river surged down a narrow gorge. The water was a clear blue and in the still pools formed behind the boulders he could see the riverbed covered in smooth, round stones. A hundred yards to their right was a twenty-foot tall waterfall that split into three channels over a jagged rock face before splashing into a pool below.

Fisher studied the GPS unit. "This is the place." He lifted his binoculars to his eyes and scanned the length of the gorge, tracking along both tree lines as far as he could see in both directions. "I don't see anything," he said.

"You are not looking in the right place," Jimiyu murmured beside him.

"What?"

Jimiyu raised a bony hand and pointed straight ahead at a thick, vine-encrusted tree jutting from the edge of the cliff. Fisher stared at it, seeing nothing for a full thirty seconds, until finally his eyes detected a too-symmetrical shape hidden in the branches: a straight vertical line, another horizontal, a gentle curve . . .

Good God. . .

What he was seeing wasn't a tree. It was the inverted tail section of an airplane.

Fisher was dumbfounded. Of course, the brother in Fisher had prayed Peter's letter had been more than the ramblings of a sick and dying man, but with the thoughts so seemingly incoherent and far removed from the core of the Carmen Hayes/PuH-19 puzzle, he'd also had his doubts.

But here it was, exactly where the latitude and longitude indicated: a plane. Now seeing it for what it was, Fisher understood how even the Turkana and Samburu, so intimately familiar with the area, had missed it. While the jungle had long ago erased any sign of the impact itself, it was clear the Sunstarhad crashed not far from here and ripped through the forest, slowing until the forward half of its fuselage had come to rest perched, hovering, at the edge of this cliff until finally, minutes or hours or days later, physics took over and it tipped over nose first and slid down the cliff face into the river below. Almost six decades of jungle foliage, mold, and lichens had enshrouded the aluminum fuselage, turning it into just another tree trunk.

Fisher dropped his pack and rifle, then pulled a sixty-foot coil of 10mm climbing rope from his pack. As Jimiyu secured the line to a nearby tree, Fisher looped together a makeshift rappelling rig. He stepped to the edge of the cliff and started down.

Pausing every few feet to poke through the vines and leaves with his knife, Fisher walked himself down the cliff until the jabbing of his knife returned not the hollow gong of aluminum, but the screeching of steel on glass. This version of Niles Wondrash's plane, a Curtiss C-46 Commando, had four fuselage windows, starting at the wing and moving forward to the cockpit windows. The cabin door was set behind these, just forward of the tail fin. Fisher saw no wings, and he assumed they'd been sheared off during the crash.

Now with a point of reference, he scaled upward, again tapping his knife. The windows were set roughly ten feet apart, so . . . He stopped climbing and studied the fuselage, trying to discern angles and shapes until finally he could make out an up-sloping curve he felt certain was the rear vertical fin. He spun his body and wedged his feet into the vines, then began cutting at the foliage with his knife until slowly, foot by foot, a patch of fuselage appeared, followed soon after by an inset hatch handle and a vertical seam. He wedged the point of his knife into the seam and began prying, moving inch by inch as though prying open a paint can. After five minutes of work, he heard a groaning screech of metal on metal. The hatch gave way and fell open. Fisher pushed off, avoiding the swinging metal, then swung back and kicked his legs through the opening and wriggled forward until his butt was resting on the hatch jamb.
