The blast of light was instantaneous. A beam of pure energy exploded across the ever-narrowing gap between Carver and the onrushing Merc. It took only a fraction of a second, then the beam was gone.

The Mercedes lurched to the left. Somewhere, deep in the unconscious, animal part of the driver’s brain, some sort of alarm signal must have registered. He slammed his foot on the brake, desperately trying to stop the car.

He had no chance. The two-ton Mercedes smashed into one of the central pillars, instantly decelerating from crazy speed to total immobility. But there was just too much speed, too much weight, too much momentum. The shattered car bounced off the pillar and skidded across the road, spinning around as it went. It finally came to a halt in the middle of the road, facing back the way it had just come.

The front of the Merc looked like a Dinky Toy hit by a baseball bat, with a gigantic U-shaped depression where the hood and engine had been. The windshield was shattered, as was every other window. The driver’s-side front wheel had splayed out from the side. On the other side, the wheel had been jammed into the bodywork. The roof had been ripped from the passenger side, jammed down into the passenger compartment, and shifted two feet to the left. The pressure from front and top had forced all four doors open.

There was no sign of movement from the passenger compartment. Carver knew that the chances of anyone surviving that kind of an impact were minimal. In the corner of his eye, he saw a car drive past him, on the other side of the road, going into the tunnel, past the Mercedes.

Meanwhile, the Fiat was completing its journey out of the tunnel. Carver caught a glimpse of shock and terror on the driver’s face. Then he noticed something else. There was a dog in the front seat. It had its tongue out, panting happily, oblivious to the destruction disappearing behind it.

Carver strapped the laser back on the gas tank of his bike. He was tempted to go down and check the wreckage to make sure the target was dead, but there was little point. In the unlikely event that anyone had survived such a devastating impact, there was nothing Carver could do about it without leaving some sort of forensic trace. And even if Ramzi Hakim Narwaz was still alive, he wasn’t going to be plotting terrorist activities anytime soon.

It was time to go. At the far end of the tunnel, Carver could see a couple of pedestrians, standing and watching, unable to decide whether to walk any closer to the scene of the accident. In the distance he could hear the mosquito whine of motorcycle engines. People were coming. They would have cameras. They would be followed by cops, ambulances, fire engines.

Carver didn’t want to be around when they got there. He needed to get away before anyone figured out that this wasn’t just an unfortunate accident. He swung the tail of his bike around 180 degrees and headed back up the exit ramp of the Alma Tunnel.

The other motorcycle pulled up two hundred meters farther up the road, on the Avenue de New York, just beyond the vast neoclassical expanse of the Palais de Tokyo, home of the Paris Museum of Modern Art.

Grigori Kursk placed his feet on the ground astride his Ducati M900 Monster, sat upright, and raised his visor. His eyes burned with the rapacious hunger of a man for whom killing was not just a job but a compulsion – one that he would gratify whether he was paid to do so or not.

He turned to look at his passenger, who was just stowing the camera in a basket on the side of the bike.

“Did you see that?” he crowed, speaking in Russian. “Did you see the look on that driver’s face? The poor bastard didn’t know what to do. Well, he’s just French pâté now!” He paused for a second, then continued more calmly, getting back to business: “Okay, that was just as easy as I promised. Now, let’s pick up the other half of the money.”

“Just pick it up fast, I’m in agony back here,” his passenger replied. “My knees are up around my ears.”

Kursk laughed. “Ha! I thought you liked it like that!”

He drove on another few meters till he found a gap in the parked cars just big enough for the bike. He positioned himself facing out from the curve, giving himself just enough clearance to see the exit of the tunnel. He then took a nightscope from the chest pocket of his biker jacket and held it up to his right eye, through the gap in his helmet. He was looking for the man who’d been on the bike at the far end of the tunnel.

Kursk knew two things about this man. He was ex-British special forces. And he was the next target.

Carver’s route out of town was simple. He planned to follow the river till he reached the périphérique, the freeway that ringed Paris, then to circle the city counterclockwise before hitting the A5 expressway away from the city to the southeast. He’d be over the Swiss border before dawn.

He was just about to open the throttle when a flash of light caught his eye, no more than a hundred meters ahead, a reflection off a glass lens. It was only there for a fraction of a second, but that was long enough to draw Carver’s attention and alert him to the curve of a motorcycle tire protruding from behind a parked car.

Someone was watching him. And he was riding straight toward them.

Carver needed to get off the road. He looked to his right. There was a turning. No good – a dead end. There was only one option now. He swung the Honda onto the broad expanse of pavement and raced past a line of trees and a low, black-painted iron railing that provided some sort of barrier between himself and whoever was waiting for him.

To his right loomed the gray white bulk of the Palais de Tokyo. Its wings wrapped around a vast expanse of open plaza that rose uphill on four levels, separated by flights of shallow steps that stretched the full width of the building. At the very back ran two rows of tall classical columns, raised on a high pediment between the two wings. Behind them was the Avenue du President Wilson, which would give him another route out of town.

Carver swerved toward the giant building, aiming the bike at the pediment. He hugged the curved wings of the plaza, racing past a knot of skateboarders huddled around a glowing joint, who looked at him in stoned bafflement. As he hit the first line of five steps, he rose in his saddle, letting his legs and arms act as shock absorbers as the Honda juddered up and over the obstruction.

With his helmet on and the engine screaming, Carver didn’t hear the gunfire. He just saw a spark of light to his left, followed instantaneously by the impact of bullets smashing into the back of the bike, punching holes in the rear mud flap, and blasting through the exhaust pipe.

Behind him, the skateboarders were woken from their trance. A couple threw themselves to the ground. The rest just ran, screaming in panic across the expanse of open stone.

Carver crouched over the handlebars, pressing his head down as low as possible as the wall next to him erupted in a spattering of miniature explosions, little puffs of stone fragments and dust. He had nowhere to go but straight ahead. Jinking his bike from side to side, he raced across the pavement, then hit the next set of steps.

He was in a heavy sweat now, almost pulling the machine beneath him over the steps by sheer physical effort and bloody-minded determination. But as his body rocked back and forth in the saddle, his mind was working on another problem. Who was shooting at him? The obvious answer was someone working with or for Ramzi Narwaz. But if he had protection, why hadn’t they defended his car? It had to be someone else. And unless the assassination party had an uninvited guest, that only left one alternative.
