A flaming tire arced downward from the conflagration, heading directly for Bourne.

Scrambling away, he rolled onto a patch of snow to keep the flames from getting to his clothes. By the time he raised himself up onto one knee, three armed Mossad agents were sprinting toward him. As the first shots were fired, he leaped behind a storage shed just past the edge of the makeshift runway.

The intensity of the fire incinerating the plane and the Jeep kept the agents from coming any closer, and Bourne took the opportunity to run in a half-crouch to the next building, which housed the scientists working in the camouflaged laboratory several hundred yards to his left.

Though well armed, Bourne had no particular desire to shoot the agents except in self-defense. It was their commander and Maceo Encarnación he was after. He’d much prefer to keep hidden and out of their way while he searched for his quarry.

No sooner had he entered the building than the door slammed shut. One of the windows shattered and a thick tongue of flame set the bedding on fire. The sharp odor of chemical fire filled the interior: someone was using a flamethrower.

The blaze leaped up, engulfing the interior almost immediately. Bourne turned back, but the door through which he had slipped in was bolted shut from the outside. He tried to make his way to one of the windows, but the fire had spread so quickly and the flames were so hot that he could not get to even the nearest of them. Ripping off a pillowcase, he held it over his nose and mouth, dropping to the floor, where the air was several degrees cooler. Acrid smoke billowed like storm clouds, obscuring the low ceiling.

He heard a sound over the spark and crackle of the burning wood. A figure filled the shattered window, then stepped through. It was clad in a flame-retardant suit with its own breathing apparatus. The figure held the flamethrower as it looked to his right, then his left. From his position hidden away beneath one of the beds, Bourne could make out the features of Colonel Ben David through the glass face-plate.

Bourne had already witnessed the first tongue of flame and so knew that the flame flower was using liquid—likely napalm—ignited by propane. Now, as Ben David turned again, searching for him, Bourne saw the two tanks on his back: The napalm would be housed in the tank that lay against his back, the propane tank, hidden from anyone standing in front of the Colonel, just behind it. Bourne brought his rifle to bear: All it would take was a single bullet into the propane tank to roast Ben David alive. But in this enclosed space, already afire, Bourne himself would roast along with his enemy.

Trying not to cough, he watched as Ben David quartered the space, searching under one bed after another. The moment he left his post in front of the shattered window, Bourne snaked out from under the bed, sprinted diagonally across the smoke- and ash-filled interior. As he left his feet, diving through the window, Ben David turned, toggling on the flamethrower. Another tongue of flame licked out, across the wall, then shot out the window, where the very end of it licked at the back of Bourne’s jacket, igniting it.

Instantly feeling the heat, Bourne threw himself into a patch of deeper snow, rolling on his back to snuff out the flames. He saw Ben David step through the window, level the snout of the flamethrower on him, even as Bourne lifted the assault rifle to shoot him.

“Stalemate,” Ben David said as he pulled off the suit’s hood. He appeared oblivious to the building burning behind him. “It seems you’re always in my way, one way or another, Bourne. What have you done with Rebeka?”

“Rebeka and I made a good team. I tried to save her.”

Ben David frowned. “What d’you mean?”

“She was killed—stabbed to death inside Maceo Encarnación’s villa in Mexico City.”

Ben David took a threatening step toward Bourne. “Goddamn you. You never should have taken her there.”

“You think her death was my fault? She was on her own mission; it coincided with mine. Besides, you sent the Babylonian to terminate her because she was getting too close to your little operation.”

“What d’you know about it?”

“Now you want me to believe you still have feelings for her?”

“I asked you—”

“I know everything, down to the counterfeit money the Chinese manufactured.”

Ben David leaned forward. “You don’t know his name.”

“You mean Minister Ouyang?”

Ben David stared at him. “Why does he hate your guts?”

Bourne stared back.

“You’re not going to screw this deal for me, Bourne.”

When Ben David tightened his finger on the trigger, Bourne said, “Don’t you want to know who killed Rebeka?”

“I don’t care. She’s dead.”

“It was Nicodemo, Ben David, Maceo Encarnación’s son.” The Colonel stood stock still. “What?”

“You didn’t know Nicodemo was your partner’s son, did you?”

Ben David said nothing, but his tongue emerged briefly to moisten his lips.

“Which means Maceo Encarnación gave the order to have her killed. I could use a partner like that.” Bourne laughed grimly. “But he’s all yours.”

“He’s playing you, Ben David.”

Both men turned at Maceo Encarnación’s growl.

“Why haven’t you killed him?” Encarnación was carrying a pistol in one hand and in the other a massive machete with an evil-looking blade. Ben David looked from Bourne to Encarnación. “Why did you have Rebeka killed?”

“What? I don’t explain my actions to anyone.”

Ben David shook his head. “You had a choice. You could have captured her—”

“Are you crazy? She was far too dangerous to try to capture. Besides, there was Bourne to deal with.”

“—but you had your son kill her anyway.”

Maceo Encarnación looked suddenly stricken. “I have no son.”

“Nicodemo. He isyour son.”

“Who told you that?” Encarnación flared.

Ben David gestured at Bourne with his head.

“And you believe him?”

“It makes too much sense to be a lie.”

Maceo Encarnación spat. “Did you even hear what I said? You’ve inhaled too much smoke. Rebeka is dead, so is Nicodemo. The past is buried. It’s our future we have to concentrate on now. Bourne is the only one standing in—”

Ben David turned the ugly snout of the flamethrower on Encarnación and pulled the trigger. A burst of napalm spat out, just missing the Mexican. Bourne was on his feet in an instant. He kicked out, sending Ben David reeling back into the flames licking out of the shattered window.

Without a backward glance, Maceo Encarnación ran around to the rear of the building. Bourne followed him at a strong lope. At the corner, a shot caused him to quickly duck back. He heard the crunch of running feet and darted around the corner, firing as he went. Maceo Encarnación had vanished. Bourne stalked after him, checking the snowy ground for his footprints. The three Mossad agents who had fired at him previously were frantically combating the fire, which had crept close to the netting that camouflaged the laboratory from both the ground and the sky.

At the end of the building Bourne saw prints leading off toward the laboratory. Having to cross unprotected ground, he moved cautiously. He was halfway across when he noticed one of the agents answer his satphone, and he hunkered down, making himself as inconspicuous as possible. The agent, covered in soot, his clothes seared and singed in places, nodded, then abandoned his comrades, racing off toward the far side of the compound. Bourne tracked him until he passed behind the burning building, then he rose, tracing Maceo Encarnación’s footprints, which led directly to the front door of the camouflaged lab. He was about to follow them when he turned, sensing movement out of the corner of his eye.
