Blue Gold

Prolog

Sao Paulo Airport, Brazil, 1991

With a POWERFUL KICK FROM ITS twin turbofan engines, the sleek executive jet lifted off the runway and shot into the vaulted skies above Sao Paulo. Climbing rapidly over the biggest city in South America, the Learjet soon reached its cruising altitude of thirty-nine thousand feet and raced toward the northwest at five hundred miles an hour. Seated in a comfortable rear-facing chair at the back of the cabin, Professor Francesca Cabral peered wistfully out the window at the cottony cloud cover, already missing the smog cloaked streets and sizzling energy of her hometown. A muffled snort from across the narrow aisle interrupted her musings. She glanced over at the snoring middle-aged man in the rumpled suit and wondered with a shake of her head what her father was thinking when he assigned Phillipo Rodriques as her bodyguard.

Extracting a folder from her briefcase, she jotted notes in the margins of the speech that she planned to deliver at an international conference of environmental scientists in Cairo. She had gone over the draft a dozen times, but her thoroughness was entirely in character. Francesca was a brilliant engineer and a highly respected professor, but in a field and society dominated by males, a female scientist was expected to be more than perfect.

The words blurred on the pages. The night before Francesca was up late packing and pulling together scientific papers. She had been too excited to sleep. Now she cast an envious glance at the snoozing bodyguard and decided to take a nap. She set the speech aside, pushed the back of her thick-cushioned seat into its reclining position, and closed her eyes. Lulled by the throaty whisper of the turbines, she soon dozed off.

Dreams came. She was floating on the sea, gently rising and falling like a jellyfish buoyed by soft billows. It was a pleasant sensation until one wave lifted her high in the air and dropped like a runaway elevator. Her eyelids fluttered open, and she looked around the cabin. She had an odd feeling, as if someone had grabbed at her heart. Yet all seemed normal. The haunting strains of Antonio Carlos Jobim's "One Note Samba" played softly over the sound system. Phillipo was still out cold. The sense that something was amiss would not go away. She leaned over and gently shook the sleeping man's shoulder. "Phillipo, wake up."

The bodyguard's hand went to the holster under his jacket, and he came instantly awake. When he saw Francesca he relaxed.

"Senhora, I'm sorry," he said with a yawn. "I fell asleep."

"I did, too." She paused as if she were listening. "Something isn't quite right."

"What do you mean?"

She laughed nervously. "I don't know." Phillipo smiled with the knowing expression of a man whose wife has heard burglars in the night. He patted her hand. "I will go see."

He got up and stretched, then went forward and knocked on the cockpit door. The door opened, and he stuck his head through. Francesca heard a murmured conversation and laughter.

Phillipo was beaming broadly when he returned. "The pilots say everything is okay, Senhora."

Francesca thanked the bodyguard, settled back in her seat, and took a deep breath. Her fears were foolish. The prospect of being freed from her mental meat grinder after two years of exhausting work had given her the jitters. The Project had consumed her, drained the hours from her days and nights, and demolished her social life. Her gaze fell on the divan that stretched across the rear of the cabin, and she resisted the impulse to see if her metal suitcase was still safely stored in the space behind the sofa cushions. She liked to think of the valise as a reverse Pandora's box. Instead of evil, good things would pour out when it was opened. Her discovery would bring health and prosperity to millions, and the planet would never be the same again.

Phillipo brought Francesca a cold bottle of orange juice. She thanked him, thinking she had grown to like her bodyguard in the short time she had known him. With his wrinkled brown suit, balding pepper-and-salt hair, thin mustache, and round spectacles, Phillipo could have passed for an absentminded academic. Francesca couldn't know that he had spent years perfecting the shy, bumbling manner. His carefully cultivated ability to merge into the background like faded wallpaper made him one of the top undercover agents in the Brazilian secret service.

Rodriques had been hand picked by her father. Francesca initially balked at her father's insistence that a bodyguard accompany her. She was far too old to have a baby-sitter. When she saw his genuine concern for her welfare, she went along. She suspected her father was more worried about good-looking fortune hunters than for her safety.

Even without her family's wealth, Francesca would have drawn male attention. In a land of dark hair and smoky complexions, she was a standout. Her blue-black almond-shaped eyes, long lashes, and almost perfect mouth were the legacy of her Japanese grandfather. Her German grandmother had passed along her light brown hair, her height genes, and the Teutonic stubbornness of the delicately sculpted jaw. Her shapely figure, she decided long ago, had something to do with living in Brazil. Brazilian women seem to have bodies especially designed for the country's national dance, the samba. Francesca had improved on the natural model by many hours spent in the gym where she went to relieve the tension of her work.

Grandfather had been a minor diplomat when the Empire of Japan ended under twin mushroom clouds. He stayed on in Brazil, married the daughter of a Third Reich ambassador similarly unemployed, became a Brazilian citizen, and switched to his first love, gardening. He moved the family to Sao Paulo, where his landscape company served the rich and powerful. He developed close ties with influential government and military figures. His son, Francesca's father, used those connections to move effortlessly to a highly placed position in the commerce department. Her mother was a brilliant engineering student who put her academic career aside to become a wife and mother. She never regretted her decision, at least not openly, but she was de lighted that Francesca would choose to follow in her academic footsteps.

Her father had suggested that she fly on his executive jet to New York, where she would meet with United Nations officials before boarding a commercial flight to Cairo. She was glad to get back to the States, if only for a short visit, and wished she could make the plane move faster. The years she had spent studying engineering at Stanford University in California would always be pleasant memories. She glanced out the window and realized she had no idea where they were. The pilots hadn't re ported on the flight's progress since the plane left Sao Paulo. Excusing herself to Phillipo, she went forward and stuck her head in the cockpit.

"Bom dia, senhores. I was wondering where we are and how much longer we'll be in the air."

The pilot was Captain Riordan, a rawboned American with crew-cut straw-colored hair and a Texas accent. Francesca had never seen him before, but that wasn't surprising. Nor was the fact that Riordan was a foreign national. Although the plane was privately owned it was maintained by a local airline that sup plied pilots.

"Bowanis deeyass," he said with a lopsided grin, his Chuck Yeager drawl and butchered Portuguese grating on her ears. "Sorry for not keeping you up to date, miss. Saw you were sleeping and didn't want to disturb you." He winked at the copilot, a thickset Brazilian whose over muscled physique suggested he spent a lot of time pumping iron. The copilot smirked as his eyes roved over Francesca's body. Francesca felt like a mother who had come upon two mischievous boys about to play a prank. "What's our timetable?" she said in a businesslike manner.

"Waall, we're over Venezuela. We should be in Miami in approximately three hours. We'll stretch our legs while we refuel and should be in New York about three hours after that."

Francesca's scientific eye was drawn to the screens on the instrument panel. The copilot noticed her interest and couldn't resist the chance to impress a beautiful woman.

"This plane is so smart it can fly itself while we watch the soccer games on TV," he said, showing his big teeth.

"Don't let Carlos blow smoke up your flue," the pilot said. "That's the EFIS, the electronic flight instrument system. The screens take the place of the gauges we used to use."

"Thank you," Francesca said politely. She pointed to another gauge. "Is that a compass?" she said.

"Sim, sim," the copilot said, proud of his successful tutelage.

"Then why does it indicate we're going almost due north?" she said with a furrowed brow. "Shouldn't we be heading in a more westerly direction toward Miami?"

The men exchanged glances. "You're quite observant, senhora," the Texan said. "Absolutely right. But in the air a straight line isn't always the fastest way between two points. Has to do with the curvature of the earth. Like when you fly from the U.S. to Europe the shortest way is up and around in a big curve. We've also got to deal with Cuban airspace. Don't want to get ol' Fidel all haired up."

The quick wink and smirk again.

Francesca nodded appreciatively. "Thank you for your time, gentlemen. It's been most instructive. I'll let you get back to your work."

"No bother, ma'am. Any time."

Francesca was fuming as she took her seat. Fools! Did they think she was an idiot? The curvature of the earth indeed!

"Everything's okay, like I said?" Phillipo asked, looking up from the magazine he was reading.

She leaned across the aisle and spoke in a low, even tone. "No, everything is not okay. I think this plane is off-course." She told him about the compass reading. "I felt something odd in my sleep. I think it was the shifting of the plane as they changed direction."

"Maybe you're mistaken."

"Perhaps. But I don't think so."

"Did you ask the pilots for an explanation?"

"Yes. They gave me some absurd story saying the shortest distance between two points was not a straight line because of the curvature of the earth."

He raised an eyebrow, apparently surprised by the explanation, but he still wasn't convinced. "I don't know . . ."

Francesca pondered some other inconsistencies. "Do you re member what they said when they came on board, about being replacement pilots?"

"Sure. They said the other pilots were called off on another job. They took their place as a favor."

She shook her head. "Peculiar. Why did they even bring it up? It's as if they wanted to head off any questions I might have. But why?"

"I have had some experience in navigation," Phillipo said thoughtfully. "I will go see for myself." He sauntered up to the cockpit again. She heard male laughter, and after a few minutes he came back with a smile on his face. The smile faded as he sat down.

"There's an instrument in the cockpit that shows the original flight plan. We are not following the blue line as we should be. You were right about the compass, too," he said. "We are not on the correct course."

"What in God's name is going on, Phillipo?"

A grave expression came onto his face. "There was something your father didn't tell you."

"I don't understand."

Phillipo glanced toward the closed cockpit. "He had heard things. Nothing that would persuade him you were in danger, but enough so that he would like the reassurance of knowing I would be nearby if you needed help."

"Looks like we could both use some help."

"Sim, senhora. But unfortunately we must do for ourselves."

"Do you have a gun?" she said abruptly.

"Of course," he said, faintly amused at the hard-nosed question from this beautiful and cultured woman. "Would you like me to shoot them?"

"I didn't mean-no, of course not," she said glumly. "Do you have any ideas?"

'A gun is not just for shooting," he said. "You can use it for intimidation, use its threat to make people do things they don't want to do."

"Like pointing us in the right direction?"

"I hope, senhora. I will go forward. I will ask them politely to land at the nearest airport, saying it is your wish. If they refuse I will show them my gun and say I would not like to use it."

"You can't use it," Francesca said with alarm. "If you put a hole in the plane at this altitude, it would depressurize the cabin, and we'd all be dead within seconds."

"A good point. It will increase their fear." He took her hand and squeezed it. "I told your father I would watch out for you, senhora. "

She shook her head as if it would make the situation go away. "What if I'm wrong? That these are innocent pilots doing their job?"

"Simple," he said with a shrug. "We call ahead on the radio, we land at the nearest airport, we bring in the police, we straighten things out, then we resume our trip."

They cut their conversation short. The door to the cockpit had opened, and the captain stepped into the cabin. He ambled forward, having to bend his head because of the low overhead.

"That was some joke you just told us," he said with his crooked grin. "Got any more?"

"Sorry, senhor," Phillipo said.

"Waall, I got one for you," the pilot replied. Riordan's droopy, heavy-lidded eyes gave him a sleepy look. But there was nothing sluggish about the way he reached behind his back and produced the pistol he had tucked in his belt.

"Hand it over," he said to Phillipo. "Real slow."

Phillipo gingerly opened his jacket wide so the shoulder holster was in plain view, then extracted his gun by the tips of his fingers. The pilot stuck the gun in his belt.

"Grazyeass, amigo," he said. "Always nice to deal with a professional." He sat on an armrest and with his free hand lit a cigarette. "Me and my partner have been talking, and we think maybe you're on to us. Figured you were checking us out when you came up a second time, so we decided to lay it all out so there won't be any misunderstandings."

"Captain Riordan, what is going on?" Francesca said. "Where are you taking us?"

"They said you were smart," the pilot said with a chuckle. "My partner never should have started bragging about the plane." He blew twin plumes of smoke from his nostrils. "You're right. We're not going to Miami, we're on our way to Trinidad."

"Trinidad?"

"I hear it's a real nice place."

"I don't understand."

"It's like this, senyoreeta. There's going to be a welcome party waiting for you at the airport. Don't ask me who they are 'cause I don't know. All's I know is we've been hired to deliver you. Things were supposed to go nice and easy. We were going to tell you we had mechanical problems and needed to land."

"What happened to the pilots?" Phillipo asked.

"They had an accident," he said with a slight shrug. He ground the cigarette butt on the floor. "Here's the situation, miss. You just stay put, and everything will be fine. As for you, cavaleiro, I'm sorry to get you in trouble with your bosses. Now I can tie you both up, but I don't think you'd try anything foolish unless you can fly this plane yourselves. One more thing. Up, partner, and turn around."

Thinking he was about to be frisked, Phillipo complied without protest. Francesca's warning came too late. The pistol barrel arced down in a silvery blur and struck the bodyguard above the right ear. The sickening crunch was drowned out by the bodyguard's cry of pain as he doubled over and crumpled onto the floor.

Francesca jumped up from her seat. "Why did you do that?" she said defiantly. "You have his gun. He couldn't harm you."

"Sorry, miss. I'm a firm believer in insurance." Riordan stepped over the prostrate form in the aisle as if it were a sack of potatoes. "Nothing like a cracked skull to discourage a man from getting into trouble. There's a first aid kit up there on the wall. Taking care of him should keep you busy 'til it's time to set down." He tipped his hand to his cap, strolled back to the cockpit, and shut the door.

Francesca knelt by the stricken bodyguard. She soaked cloth napkins in mineral water and cleaned the wound, then applied pressure until the bleeding was stanched. She daubed an antiseptic on the scalp cut and the bruised skin around it, wrapped ice in another napkin, and pressed it to the side of the man's head to prevent swelling.

As Francesca sat by his side, she tried to piece the puzzle together. She ruled out a kidnapping for money. The only reason someone would go through this much trouble would be for her process. Whoever was behind this mad scheme wanted more than a scale model and the papers explaining her work. They could have broken into the lab or grabbed her luggage at the airport. But they needed Francesca to interpret her findings. Her process was so arcane, so different, that it didn't conform to the norms of science, which is why no one had thought of it before.

The whole thing didn't make sense! Within a day or two she was going to give the process to the countries of the world for nothing. No patents. No copyright. No royalty fees. Absolutely free of charge. Anger smoldered in her breast. These ruthless people were stopping her from improving the lot of millions.

Phillipo groaned. He was coming around. His eyes blinked open and came into focus.

"Are you all right?" she said.

"It hurts like the devil, so I must be alive. Help me sit up, please."

Francesca put her arm around Phillipo and lifted until he sat with his back against a seat. She unscrewed a bottle of rum from the bar and put it to his lips. He sipped some liquor, managed to keep it down, then took a healthy swallow. He sat there for a moment waiting to see if his guts would come up. When he didn't vomit, he smiled. "I'll be fine. Thank you."

She handed him his glasses. "I'm afraid they were broken when he hit you."

He tossed them aside. "They are only plain glass. I can see fine without them." The level eyes that bored into Francesca were not those of a frightened man. He glanced at the closed cockpit door. "How long have I been out?"

"Twenty minutes, maybe."

"Good, there is still time."

"Time for what?"

His hand slid down to his ankle and came up filled with a snub-nosed revolver.

"If our friend hadn't been so anxious to give me a headache, he would have found this," he said with a grim smile.

This was definitely not the same rumpled man who had seemed more like an absentminded professor than a bodyguard. Francesca's elation was tempered by reality. "What can you do? They have at least two guns, and we can't fly the plane."

"Forgive me, Senhora Cabral. Another failure to be forthright on my part." Sounding almost guilty, he said, "I forgot to mention that I was in the Brazilian air force before I joined the secret service. Please help me up."

Francesca was speechless. What other rabbits would this man pull out of his hat? She gave him a hand until he was able to stand on shaky legs. After a minute a new strength and determination seemed to flow through his body. "Stay here until I tell you what to do," he said with the air of a man used to people obeying his command.

He went forward and opened the door. The pilot glanced over his shoulder and said, "Hey, look who's back from the land of the living dead. Guess I didn't hit you hard enough."

"You don't get a second chance," Phillipo said. He jammed the revolver barrel under the Texan's ear hard enough to hurt. "If I shoot one of you, the other can still fly. Which one will it be?"

"Christ, you said you took his gun!" Carlos said.

"You've got a short memory, cavaleiro," the pilot replied calmly. "You shoot us and who's going to fly the plane?"

"I will, cavaleiro. Sorry I didn't bring my pilot's license with me. You'll have to take my word for it."

Riordan turned his head slightly and saw the cold smile wreathing the bodyguard's face.

"I take back what I said about dealing with a professional," Riordan said. "What now, partner?"

"Give me the two guns. One at a time."

The pilot handed over his pistol and the one he had taken from Phillipo. The bodyguard passed the weapons back to Francesca, who had come up behind him.

"Get out of your seat," he ordered, backing into the cabin. "Slowly."

Riordan caught the copilot's eye and levered himself out of his seat. Using his body to shield the gesture, he made a quick palm-down flip with his hand. The copilot nodded almost imperceptibly to show he understood.

The pilot followed Phillipo as if drawn by an imaginary leash, as the bodyguard backed up into the cabin. "I want you to go lie facedown on the divan," Phillipo said, keeping his gun pointed at Riordan's chest.

"Hell, I was hoping I could take a nap," the pilot said. "That's real kind of you."

Francesca had backed off the aisle to make room for the two men to pass. Phillipo asked her to get some plastic trash bags from under a front seat. Phillipo intended to use the bags to bind the pilot. With Riordan on ice he would only have to deal with the copilot.

The cabin was about twelve feet long. In the tight space Phillipo had to step aside to let the other man pass. He re minded Riordan not to try anything at close quarters, because it would be impossible to miss. Riordan nodded and stepped to ward the rear. They were only a few inches apart when the co pilot put the plane over on its left side.

Riordan had expected the move, but he didn't know when it would come or that it would be so violent. He lost his balance and was thrown onto a seat, his head slamming into the bulkhead. Phillipo was lifted off his feet. He flew across the cabin and landed on top of Riordan.

The pilot disentangled his right hand and blasted his big fist into the bodyguard's jaw. Phillipo saw galaxies whirling over his head and almost blacked out, but he managed to keep a death grip on the gun. Riordan brought his arm back for another punch. Phillipo blocked it with his elbow.

Both men were street fighters. Phillipo clawed at Riordan's eyes. The pilot bit Phillipo on the fleshy part of the palm. The bodyguard jammed his knee into Riordan's groin, and when the pilot opened his mouth, Phillipo snapped his head forward, smashing the cartilage in Riordan's nose. He might have gained the upper hand, but at that point the copilot made the plane yaw sharply to the right.

The struggling men flew across the aisle into the opposite seat. Now the American was on top. Phillipo tried to club Riordan with the gun's muzzle, but the pilot grabbed his wrist with two hands and twisted it away and down. Phillipo was strong, but he was no match for the double-teamed assault. The barrel swung closer to his midsection.

The pilot had his hands on the gun and was wrestling it away. Phillipo tried to hold on to the pistol, almost had control of it again, but the grip was slippery from the jets of blood flowing from Riordan's nose. In a wrenching twist the pilot took control of the gun, got his fingertip onto the trigger, and squeezed.

There was a muffled crack! Phillipo's body jerked and then went limp as the bullet plowed into his chest.

The plane righted itself as the copilot put it back into its nor mal position. Riordan stood and staggered toward the cockpit. He stopped and turned, apparently sensing something wasn't right.

The gun he had left behind was propped up on the body guard's chest. Phillipo was trying to steady it for a shot. Riordan charged like a wounded rhino. The pistol cracked. The first bullet hit the pilot in the shoulder, and he kept coming. Phillipo's brain died, but his finger twitched twice more. The second shot caught the pilot in the heart and killed him instantly. The third went wild and missed him completely. Even as the pilot crashed to the floor, the pistol had dropped from Phillipo's hand.

The struggle from one side of the cabin to the other had taken only a few seconds. Francesca had been thrown between the seats and played possum as the bloodied pilot was making his way back to the cockpit. The shots sent her down again.

She cautiously stuck her head into the aisle and saw the pilot's still body. She crawled over to Phillipo's side, pried the pistol from his bloody hands, and approached the cockpit door, too enraged to feel fear. Her anger quickly turned to shock.

The copilot was slumped forward, his body held in place by his seatbelt. There was a bullet hole in the partition separating the cockpit from the cabin and through the back of the copilot's chair. Phillipo's third shot.

Francesca pulled the copilot upright. His groan told her he was still alive.

"Can you talk?" she said.

Carlos rolled his eyes and whispered a hoarse "Yes."

"Good. You've been shot, but I don't think it hit any vital organs," she lied. "I'm going to stop the bleeding."

She retrieved the first aid kit, thinking that what she really needed was an emergency-room trauma unit. She almost fainted at the sight of the blood flowing from the wound down his back to puddle on the floor. The compress she applied immediately turned scarlet, but it may have helped stanch the loss of blood. It was impossible to tell. The only thing she knew for certain was that the man was going to die.

With fearful apprehension she looked at the glowing instrument panel, numbed by the realization that this dying man was the key to her survival. She had to keep him alive.

Francesca retrieved the bottle of rum and tilted it to the copilot's lips. The rum dribbled down his chin, and the little amount he swallowed made him cough. He asked for more. The strong liquor brought color to his pale cheeks and the gleam of life back into the glazed eyes.

She put her lips close to his ear. "You must fly," she said levelly. "It's our only chance."

The proximity of a beautiful woman seemed to give him energy. His eyes were glassy but alert. He nodded and reached out with shaking hand to flick on the radio that connected him directly with traffic control in Rio. Francesca eased into the pilot's seat and slipped on the headset. The voice of the traffic controller came on. Carlos asked for help with his eyes. Francesca began to talk, explaining their predicament to traffic control.

"What do you advise us to do?" she said.

After an agonizing pause the voice said, "Proceed to Caracas immediately."

"Caracas too far," Carlos croaked, mustering the strength to talk. "Someplace closer."

Several more moments dragged by.

The dispatcher's voice came back. "There's a small provincial airstrip two hundred miles from your position at San Pedro, out side Caracas. No instrument approach, but the weather is perfect. Can you make it?"

"Yes," Francesca said.

The copilot fumbled with the keypad of the flight computer. With all the strength at his command he called up the international identifier for San Pedro and entered it in the computer.

Guided by the computer, the plane began to make a turn.

Carlos smiled slightly. "Didn't I tell you this plane flies by itself, senhora?" His wheezy words had a drowsy quality to them. He was obviously becoming weaker from loss of blood. It was only a matter of time before he passed out.

"I don't care who flies it," she said sharply. "Just get us on the ground."

Carlos nodded and set up the automatic descent profile on the flight computer to take the plane down to two thousand feet. The plane began to descend through the clouds, and before long patches of green were visible. The sight of land reassured and terrified Francesca at the same time. Her terror rose a few degrees when Carlos shuddered as if an electric current had gone through him. He grabbed Francesca's hand and held it in a death grip.

"Can't make San Pedro," he said, his voice a wet rattle.

"You've got to," Francesca said.

"No use."

"Damn it, Carlos, you and your partner got us into this mess, and you're going to get us out of it!"

He smiled vacantly. "What are you going to do, senhora, shoot me?"

Her eyes blazed. "You'll wish I had if you don't get this thing down."

He shook his head. "Emergency landing. Our only chance. Find a place."

The big cockpit window offered a view of the thick-grown rain forest. Francesca had the feeling she was flying over a vast unbroken field of broccoli. She scanned the endless greenery again. It was hopeless. Wait. Sunlight glinted off something shiny.

"What's that?" she said, pointing.

Carlos disconnected the auto pilot and auto throttles, took the wheel in his hands, and steered toward the reflection, which came from the sun glinting off a giant waterfall. A narrow, meandering river came into view. Alongside the river was an irregularly shaped clearing of yellow and brown vegetation.

Flying almost on automatic himself, Carlos passed the open area and set up a thirty-degree banking turn to the right. He ex tended the wing flaps and put the plane in a boxlike flight pat tern. With a hard right he prepared the plane for its final approach. They were at eighteen hundred feet, descending on a long, shallow glide. Carlos extended the wing flaps to slow them down further.

"Too low!" he growled. The treetops were rushing at them. With superhuman strength born of desperation he reached out and gave the throttles more power. The plane began to rise.

Through blurred vision he scoped the final approach. His heart fell. It was a terrible landing field, small and lumpy, the size of a postage stamp. They were doing a hundred and sixty miles per hour. Too fast.

A soggy gasp escaped from his throat. His head lolled onto his shoulder. Blood gushed from his mouth. The fingers that had clutched the wheel so tightly were curled in a useless death grip. It was a tribute to his skill that in his last moments he had trimmed the plane perfectly. The jet maintained trim, and when it hit the ground, it bounced into the air a few times like a stone skipped across water.

There was an ear-splitting shriek of tortured metal as the bottom of the fuselage made contact with the earth. The friction between the plane and the solid earth slowed it down, but it was still going more than a hundred miles an hour, the fuselage cut ting through the ground like the blade of a plow. The wings snapped off, and the fuel tanks exploded, leaving twin black and orange swaths of fire in the plane's wake for another thousand feet as it hurtled toward a bend in the river.

The plane would have disintegrated if the grass-covered ground had not given way to the soft, marshy mud along the riverbank. Stripped of its wings, its blue and white skin splattered with mud, the plane looked like a giant wormlike creature trying to burrow into the mire. The plane skidded over the surface of the muck and finally came to a lurching stop. The impact hurled Francesca forward into the instrument panel, and she blacked out.

Except for the crackle of burning grass, the ripple of river water, and the hiss of steam where the hot metal touched the water, all was silent.

Before long, ghostly shadows emerged from the forest. As quiet as smoke, they moved in closer to the shattered wreckage of the plane.

San Diego, California, 2001
