Fisher did the conversion in his head: about fourteen miles per hour for 150 miles. It would be just enough to reach the crash site and get back to Kapedo. From here all the way to Lake Turkana they would be crossing through the Eastern Rift Valley and Great Rift Valley, which as a whole ran over 3,500 miles, from Syria in the north to Mozambique in south. Formed by the sinking and tearing of the earth’s crust along a tectonic plate that was fifty million years old, the Rift Valley was an ecosystem unto itself, ranging in elevation from 6,000 feet above sea level here in Kenya to 1,400 feet below sea level at the shores of the Dead Sea, and ranging in width from less than a mile to more than one hundred miles.
On the flight to Nairobi, Fisher had studied satellite maps of the area. The seventy miles of river from Kapedo to Peter’s mystery coordinates flowed ever downward through thick, triple-canopy jungle, boiling gorges, and past towering escarpments, until bottoming out at nearly six hundred feet below sea level in a valley that probably hadn’t seen more than a hundred white footprints in its history. If that’s where the Sunstar had gone down, it was no wonder it had remained lost for almost sixty years.
Jimiyu climbed into the stern, and Fisher handed him the extra fuel and water cans, four steel ammunition boxes full of rations and supplies, then cast off the lines and jumped in. Jimiyu braced his bony leg against the dock, pushed off, then pull-started the engines and opened the throttle.
For the next two hours they glided down the river, passing villages and other boats, most of them narrow-beamed fishing dhows. Jimiyu seemed to know everyone, waving and smiling and calling out in Swahili as they passed by, but for the most part the river was empty of traffic. Jimiyu whistled to himself, one hand on the throttle, the other resting on the stock of a vintage Mauser bolt-action rifle. Though his expression was one of contentment, Fisher could see his eyes constantly scanning, from the riverbanks and across the muddy brown water ahead and to the sides.
“Crocodiles?” Fisher asked at one point.
“Oh, yes, very big. And koboku,” he said, and opened his mouth wide and chomped down. “Hippo, too. Watch for floating logs. They might not be logs, understand?”
“I understand,” Fisher said and fingered his own rifle. Though opinions varied, it was widely accepted that hippos killed more people in Africa than all other animals combined. A bull hippo can weigh as much as six thousand pounds, has razor-sharp tusks, a nasty disposition, and can run, at a sprint, over thirty miles per hour.
Fisher couldn’t help but smile. Throughout his career he’d been shot at, stabbed, clubbed, and everything in between. He’d jumped from airplanes at thirty-five thousand feet, piloted minisubmarines, and technically invaded dozens of countries. For some reason, the idea of being killed by a hippo while tooling down a jungle river in the Great Rift Valley while trying to solve one of the twentieth century’s most enduring mysteries amused him. All things considered, there were worse ways to go.
Sam Fisher, koboku fodder.
“There!” Jimiyu called, pointing toward the bank. “Koboku!”
To the left in a shallow cove, were a dozen curved brown backs jutting from the water. As one, lined up as though waiting for a show to start, the hippos studied them, eyes barely visible above the surface of the water, ears twitching.
Jimiyu put the rudder over, steering right to give the pod a wide berth. He caught Fisher’s astonished expression and grinned. “Impressive, are they not?”
Fisher could only nod, eyes still fixed on the gallery of hippos receding in their wake. Each one had been the size of a VW Beetle.
A few minutes later, Jimiyu said, “Irving tells me you are looking for a plane.”
“That’s true.”
“The Sunstar.”
“Yes.”
“Old legend, that one.”
“What’s your opinion?” Fisher asked. “You know the area we’re headed?”
Jimiyu thought for a moment, biting the inside of his lip. “Yes, very well. Many people have come looking for the Sunstar, but no one’s looked in this place yet.” He shrugged. “Who knows?”
Fisher didn’t respond. From his expression, Jimiyu seemed to be still considering his answer. “I think it is either lost in the Rift or somewhere in Turkana. Lake Turkana, you know.”
“I know.”
“That lake — everyone thinks it is very shallow. Mostly it is, but there are parts that aren’t so shallow.” He grinned knowingly. “If we do not find it here, you and I, we will rent a submarine and look in Turkana, okay?”
Fisher smiled back. “Okay.”

They’d arrived at their campsite — a flat section of beach in a gorge — in the late afternoon the day before, and though there was still four hours of daylight left, they both decided to get a fresh start the next morning. Peter’s coordinates were four miles away, to the northwest. With luck, they could start at dawn, reach the site by midday, and be back to the campsite by nightfall.
They spent the remaining hours of daylight gathering firewood, and then, as Fisher got the fire started, Jimiyu disappeared into the jungle for an hour and returned carrying what looked like a large rat. It was, in fact, a rat, Fisher learned, but charred over the fire it tasted, predictably, like rubbery chicken. After supper, Jimiyu made coffee in a rust-spotted enamel pot, then tossed the remaining wood on the fire and slung a pair of netted sleeping hammocks from trees along the edge of the beach.
Fisher eased 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.
