The helicopters settled onto the tarmac and, one by one, killed their engines. From the two flanking aircraft emerged a security detail fit for a Russian president: big boys, well groomed, heavily armed, hard as nails. After establishing a perimeter around the third helicopter, one guard stepped forward and opened the cabin door. For a long moment, no one appeared. Then came a flash of lustrous blond hair, framing a face of Slavic youth and perfection. The features were instantly recognizable to the control tower as well as the members of the Moscow delegation. The woman had appeared on countless magazine covers and billboards, usually with far less clothing than she was wearing now. Her name had once been Yekaterina Mazurov. Now she was known as Yekaterina Kharkov. Though meticulously coiffed and painted, she was clearly on edge. Immediately after placing an elegant boot on the tarmac, she gave one of the bodyguards a good tongue-lashing, which, unfortunately, could not be heard. Someone in the Moscow delegation pointed out that Yekaterina’s anxiety was to be forgiven. She was about to become a mother of two and was still little more than a child herself.

The second person to emerge from the helicopter was a trim man in a dark overcoat with a face that hinted of ancestors from deep in Russia ’s interior. He was holding a cell phone to his ear and appeared to be engaged in a conversation of great import. No one in the control tower or the Moscow delegation recognized him, which was hardly surprising. Unlike the ravishing Yekaterina, this man’s photograph never appeared in the papers, and few people outside the insular world of the siloviki and the oligarchs knew his name. He was Oleg Rudenko, a former colonel in the KGB who now served as chief of Ivan Kharkov’s personal security service. Even Rudenko was the first to admit the title was merely an honorific. Ivan called all the shots; Rudenko just made the trains run on time. Thus the cell phone pressed tightly to his ear and the grim expression on his face.

The interval between Rudenko and the emergence of the third passenger was eighty-four long seconds, as timed by the control tower staff. He was an immensely powerful-looking figure, somewhat short in stature, with angular cheekbones, a pugalist’s broad forehead, and coarse hair the color of steel wool. One of the officials briefly confused him for a bodyguard, which was a common mistake and one he secretly enjoyed. But any inclination to such thinking was immediately dispelled by the cut of his magnificent English overcoat. And by the manner in which his trousers broke across his handmade English shoes. And by the way his own bodyguards seemed to fear his very presence. And by the sundial-sized gold watch on his left wrist. Look at him, murmured someone in the Moscow delegation. Look at Ivan Borisovich! The controversy, the arrest warrants, the indictments in the West: any one of them would have gladly accepted it all, just to live like Ivan Borisovich for a day. Just to ride in his helicopters and his limousines. And just to climb into bed one time with Yekaterina. But why the frown, Ivan Borisovich? Today is a joyous occasion. Today is the day your children are coming home from America.

He strode across the tarmac, Yekaterina on one side, Rudenko on the other, bodyguards all around. The head of the delegation, deputy foreign minister so-and-so of department such-and-such, met him halfway. Their conversation was brief and, by all appearances, unpleasant. Afterward, each retreated to his respective corner. When asked to recount what Ivan had said, the deputy refused. It couldn’t be repeated in polite company.

Look at him! Look at Ivan Borisovich! The fancy American helicopter, the beautiful young wife, the mountain of money. And underneath it all, he was still a KGB hood. A KGB hood in a fancy English suit.

LIKE OLEG Rudenko, Adrian Carter was at that moment holding a telephone to his ear, a secure landline device connected directly to the Global Ops Center at Langley. Shamron had a phone to his ear as well, though his was connected to the Operations Desk at King Saul Boulevard. He was staring at the clock while at the same time battling a crippling craving for nicotine. Smoking was strictly forbidden in the annex. So, apparently, was speaking because Carter had not uttered a word in several minutes.

“Well, Adrian? Is he there or not?”

Carter nodded his head vigorously. “The spotter just confirmed it. Ivan’s birds are on the ground.”

“How long until the plane gets there?”

“Seven minutes.”

Shamron looked at the Moscow clock: 8:53.

“Cutting it a little close, aren’t they?”

“We’re fine, Ari.”

“Just make sure they switch on those jammers at 9:05, Adrian. Not a second sooner, not a second later.”

“Don’t worry, Ari. No phone calls for Ivan. No phone calls for anyone.”

Shamron looked at the clock: 8:54.

Silence, speed, timing…

All they needed now was a bit of luck.

HAD UZI Navot been privy to Shamron’s thoughts, he would have surely recited the Office maxim that luck is always earned, never bestowed. He would have done so because at that moment he was lying on his face in the snow, one hundred yards behind the dacha, a weapon bearing his name cradled in his arms. Fifty yards to his right, in precisely the same position, was Yaakov. And fifty yards to his left was Oded. Standing directly in front of each of them was a Russian. It had been five hours since Navot and the others had crept into position through the birch forest. In that time, two shifts of guards had come and gone. There had been no relief, of course, for the visiting team. Navot, though properly outfitted for such an operation, was trembling with cold. He assumed Yaakov and Oded were suffering as well, though he had not spoken to either man in several hours. Radio silence was the order of the morning.

Navot was tempted to feel sorry for himself, but his mind would not allow it. Whenever the cold started to eat at his bones, he thought about the camps and the ghettos and terrible winters his people had endured during the Shoah. Like Gabriel, Navot owed his very existence to someone who had summoned the courage, the will, to survive those winters-a paternal grandfather who had spent five years toiling in the Nazi labor camps. Five years living on starvation rations. Five years sleeping in the cold. It was because of his grandfather that Navot had joined the Office. And it was because of his grandfather that he was lying in the snow, one hundred yards behind a dacha, surrounded by birch trees. The Russian standing before him would soon be dead. Though Navot was not an expert like Gabriel and Mikhail, he had done his obligatory time in the army and had undergone extensive weapons training at the Academy. So, too, had Yaakov and Oded. For them, fifty yards was nothing, even with frozen hands, even with suppressors. And there would be no going for the comfort zone of the torso. Only head shots. No dying calls on the radio.

Navot rolled his left wrist toward him a few degrees and glanced at his digital watch: 8:59. Six more minutes to contend with the cold. He flexed his fingers and waited for the sound of Gabriel’s voice in his miniature earpiece.

THE SECOND and final session of the emergency G-8 summit convened at the stroke of nine in the ornate St. George’s Hall of the Great Kremlin Palace. As always, the American president arrived precisely on time and settled into his place at the breakfast table. As luck would have it, the British prime minister had been placed to his right. The Russian president was seated opposite between the German chancellor and the Italian prime minister, his two closest allies in Western Europe. His attention, however, was clearly focused on the Anglo-American side of the table. Indeed, he had fixed both English-speaking leaders with his trademark stare, the one he always adopted when he was trying to look tough and decisive to the Russian people.
