The Doomsday Key

Turning a corner, Jason fell over the first body, a teenage boy, sprawled in the alley between the ramshackle hovels that passed for homes here. The teenager had been shot and trampled over. Jason crabbed away from his body and gained his feet. He fled away.

After another frantic hundred yards, he reached the northern edge of the camp. Bodies were sprawled everywhere, piled on one another, men, women, children. It was a slaughterhouse. Some bodies had been torn in half by machine-gun fire. Across the killing field, the research camp's Quonset huts stood like dark ships mired in the West African sava

Krista...

Jason remained frozen in place. He wanted to continue onward, cursing his cowardice. But he couldn't move. Tears of frustration rose to his eyes.

Then a thump-thump rose behind him. He twisted around as a pair of helicopters flew low toward the besieged camp, hugging the terrain. It had to be government forces from the nearby base. The Viatus Corporation had scattered bushels of U.S. dollars to insure extra protection for the site.

A shuddering breath escaped Jason. The helicopters would surely chase off the rebels. More confident, he headed across the field. Still, he kept low as he ran. He aimed for the back of the closest Quonset hut, less than a hundred yards away. Deeper shadows would hide him there, and Krista's lab was in the next hut over. He prayed she'd kept herself hidden inside there.

As he reached the Quonset's rear wall, bright light flared behind him. A brilliant searchlight speared out of the lead helicopter and swept across the refugee camp below. Jason let out a rattling sigh.

That should scare off the rebels.

Then, from both sides of the helicopter, the chatter of machine-gun fire blasted out and ripped into the camp. Jason's blood iced. This was no surgical strike against invading rebel forces. This was a wholesale slaughter of the camp.

The second helicopter swung to the other side, circling outward along the periphery of the camp. From its rear hatch, barrels rolled out and exploded on impact, casting up gouts of flames into the sky. Screams erupted even louder. Jason spotted one man fleeing off into the desert, naked, but with his skin still on fire. The firebombing spread toward Jason's position.

He turned and ran past the Quonset hut.

The fields and granaries spread ahead of him, but no safety would be found there. Dark figures moved on the far side of the corn rows. Jason would have to risk a final dash across the open to reach Krista's research lab. The windows were dark, and the only door faced the open fields.

He paused to steady himself. One fast dash and he could be inside the hut. But before he could move, new jets of flame burst forth on the far side of the field. A line of men bearing flamethrowers set off down the rows of corn, burning the fields that had yet to be harvested.

What the hell's happening?

Off to the right, the single granary tower exploded in a fiery whirlwind that spiraled high into the air. Shocked, but using the distraction, Jason dashed to the Quonset hut's open door and dove through it.

In the glow of the fires, the room looked unmolested, almost tidy. The back half of the hut was full of all ma

A single laptop, still powered by the batteries, glowed with a screensaver. It rested in Krista's cubicle, but there was no sign of his girlfriend.

Jason hurried to the cubicle and brushed his thumb over the touch-pad. The screensaver vanished, replaced with a view of an open e-mail account. Again it was Krista's.

Jason stared around the hut.

Krista must have fled, but where?

Jason quickly accessed his own e-mail account and toggled the address for his father's office on Capitol Hill. Holding his breath, he typed rapidly as he described the attack in a few terse sentences. In case he didn't make it, he wanted some record. Just before he hit the Send button, he had a moment of insight. Krista's files were still up on the screen. He dragged them, attached them to his note, and hit Send. She would not want them lost.

The e-mail failed to immediately transmit. The attached file was huge and would take an extra minute to upload. He couldn't wait. Jason hoped the battery pack would last long enough for the e-mail to go through.

Fearful of waiting any longer, Jason swung toward the door. He had no way of knowing where Krista had gone. He hoped she had fled into the surrounding desert. That was what he was going to do. Out there were mazes of gullies and dry washes. He could hide for days if necessary.

As he hurried toward the exit, a dark figure appeared and blocked the doorway. Jason fell back with a gasp. The figure stepped into the hut and whispered in surprise.

"Jase?"

Relief flushed through him.

"Krista..."

He hurried to her, his arms wide to take her in. They could still both escape.

"Oh, Jason, thank God!"

His relief matched hers-until she lifted a pistol and fired three times into his chest. The shots felt like punches, knocking him backward to the floor. Fiery pain followed, turning the night even darker. Distantly he heard gunfire, explosions, and more screams.

Krista leaned over him. "Your tent was empty. We thought you'd escaped."

He coughed, unable to answer as blood filled his mouth.

Seemingly satisfied with his silence, she turned on a heel and headed back out into the nightmare of fire and death. She stopped, momentarily silhouetted against the flaming fields, then vanished into the night.

Jason struggled to comprehend.

Why?

As darkness folded over him, he would have no answer to his question, but he alone heard one last thing. The laptop in the neighboring cubicle chimed. His message had been sent.

Chapter 2

October 10, 7:04 A.M.

Prince William Forest Virginia

He needed more speed.

Hunched over the narrow handlebars of the motorcycle, Commander Grayson Pierce flew the bike around a sharp corner. He leaned his six-foot frame into the curve, nearly shearing off his kneecap as he laid the bike low around the turn.

The engine roared as he opened the throttle and straightened his trajectory. His target raced fifty yards ahead of him, riding a smaller Honda crotch rocket. Gray pursued on an older-model Yamaha V-Max. Both bikes were powered by V-4 engines, but his motorcycle was larger and weighed more. If he was going to catch his target, he would need every bit of skill.

And maybe a bit of luck.

They'd reached a short straightaway through the parklands of Prince William Forest. A dense line of hardwoods framed the two-lane road. The mix of towering beech and aspen made for a handsome scenic drive, especially now, in October, when the leaves were changing. Unfortunately, a storm last night had blown most of those leaves into patches of slippery mire on the blacktop.

Gray snapped the throttle wider. Acceleration kicked him in the pants. With the slightest wobble, the bike rocketed down the straight stretch, turning the center line into a blur.

But his target was also taking advantage of the straight road. So far, most of Route 619 had been a roller-coaster ride of sudden turns, deadly switchbacks, and rolling hills. The hour-long chase had been brutal, but Gray could not let the other rider escape.

As his target slowed for the next turn, the distance between them narrowed. Gray refused to let up. Maybe it was foolhardy, but he knew his bike's capabilities. Since acquiring it, he'd had one of the robotics engineers from DARPA-the Defense Department's research and development branch-outfit the motorcycle with a few modifications.
