one guard to emerge. That left the driver and three remaining bodyguards inside the car with Khalid Murat. As Arsenov turned away, the figure sighted on his head. Through the scope, he noted the expression of command plastered on Arsenov's face. Then he moved the barrel in a smooth, practiced motion, this time sighting on the Chechen's thigh. The figure squeezed off a shot and Arsenov grabbed his left leg, shouting as he went down. One of the guards ran to Arsenov, dragged him to cover. The two remaining guards, swiftly determining where the shot had come from, ran across the street, entering the building on whose roof the figure crouched.
As three more rebels appeared, racing out a side entrance to the hospital, the assassin dropped the Sako. He watched now as the vehicle containing Khalid Murat slammed into reverse. Behind and below him, he could hear the rebels pounding up the stairs leading to his rooftop perch. Still unhurried, he fitted titanium and corundum spikes to his boots. Then he took up a composite crossbow and shot a line into a light pole just behind the middle vehicle, tying off the line to make sure it was taut. Shouting voices reached him. The rebels had gained the floor directly below him.
The front of the vehicle was now facing him as the driver tried to maneuver it around the huge chunks of concrete, granite and macadam that had erupted in the explosion. The assassin could see the soft glint of the two panes of glass that comprised the windshield. That was the one problem the Russians had yet to overcome: Bullet-proofing the glass made the panes so heavy it required two of them for the windshield. The personnel carrier's one vulnerable spot was the strip of metal between the two panes. He took the sturdy metal loop attached to his harness and snapped himself to the taut line. Behind him, he heard the rebels burst through the door, emerging onto the roof a hundred feet away. Spotting the assassin, they swung around to fire on him as they ran toward him, setting off an unnoticed trip wire. Immediately, they were engulfed in a fiery detonation from the last remaining packet of C4 the assassin had planted the night before. Never turning around to acknowledge the carnage behind him, the assassin tested the line and then launched himself from the rooftop. He slid down the line, lifting his legs so that the spikes were aimed at the windshield divider. Everything now depended on the speed and the angle with which he would strike the divider between the bullet-proof panes of the windshield. If he was off by just a fraction, the divider would hold and he had a good chance of breaking his leg.
The force of the impact ran up his legs, jolting his spine as the titanium and corundum spikes on his boots crumpled the divider like a tin can, the panes of glass caving in without its support. He crashed through the windshield and into the interior of the vehicle, carrying with him much of the windshield. A chunk of it struck the driver in the neck, half-severing his head. The assassin twisted to his left. The bodyguard in the front seat was covered in the driver's blood. He was reaching for his gun when the assassin took his head between his powerful hands and broke his neck before he had a chance to squeeze off a round.
The other two bodyguards in the jumpseat just behind the driver fired wildly at the assassin, who pushed the bodyguard with the broken neck so that his body absorbed the bullets. From behind this makeshift protection, he used the bodyguard's gun, fired precisely, one shot through the forehead of each man.
That left only Khalid Murat. The Chechen leader, his face a mask of hatred, had kicked open the door and was shouting for his men. The assassin lunged at Murat, shaking the huge man as if he were a water rat; Murat's jaws snapped at him, almost taking off an ear. Calmly, methodically, almost joyously he seized Murat around the throat and, staring into his eyes, jabbed his thumb into the cricoid
