IT HAD BEEN MADE TO LOOK AS IF HE HAD SHOT HIMSELF IN THE TEMPLE WITH THE GUN.

MOSCOW

Dr. Anatoli Nikolayev was an old man, and the summer heat was oppressive to him as he hauled his thin body up the dark narrow stairs. He wasn't sure that he wanted the answers that he had come here to find. Yet with everything that he'd learned so far he couldn't simply turn his back like an old lover who'd found out he'd been betrayed.

His research was almost finished. He had ground his way through a million pages of old records, starting in 1917 with the Soviet Union's first secret intelligence service, the Cheka, until the breakup under Gorbachev and the dismantling of the KGB in 1991; the kidnappings and terrorism and sabotage; poisons, electric guns, honey traps, brainwashings, intimidation of countless thousands of officials and diplomats from nearly every country in the world. And assassination. The ultimate act of the state other than war. Bodies stretching back almost ninety years; piled to the rafters; more bodies than even Hitler had been credited with, making him wonder why the Soviet Union hadn't been as reviled as the Nazis were.

His boney, blue-veined left hand trailed along the cracked plaster wall, and he could smell the terror in the stifling air like last night's cabbage dinner; urine and shit from the overflowing communal toilets; the accumulated filth of ninety years of neglect.

When the KGB came it was almost always easier to commit suicide the moment the knock came on the door than to endure what would come next. But all of that was finally coming to an end. The money to operate the vast worldwide spy network was drying up.

Sleeper agents in place for years, some of them for thirty years or more, were being cut free from funds. Forgotten about. Their original missions no longer valid. They were the unmentionables. No one at the Kremlin wanted to know about them, let alone speak their names.

That meant trouble was coming. Agents cut off with no way out became desperate men. And desperate men sometimes did horrible things.

He stopped on the third floor landing in the rundown apartment building a few blocks north of the Bolshoi Theater and stared at the small, dirty window at the end of the hall. He waited patiently to catch his breath. His longish white hair was plastered to his neck. His research was finished and he was afraid to think about what he had uncovered. What might be about to happen. He needed names. A way to stop the madness that he had been a part of a long time ago.

Last of three doors in the corridor. He'd asked at the Pivnoy Bar around the corner on Stoleshinkov pereulok for the exact address. General Gennadi Zhuralev lived alone with his books; no friends, no lovers, no trouble except his lights, which were always on until dawn. No one had thought to ask why.

"Tall man, was he? Broad shoulders, big ears, scar on his forehead?"

"No taller than average, but he always carries a canvas satchel. Heavy. Books maybe, certainly not money."

Dr. Nikolayev tried to dredge up a personal memory of the face from his own days as a psychologist with the KGB. But he could not. Zhuralev worked for General Baranov and the crowd in Department Viktor; assassinations, executive actions, they were called; wet affairs, mokrie dela, the spilling of blood; formerly the Thirteenth Department or Line F. It was Division 17 now though no one outside the SVR's First Chief Directorate was supposed to know it. He would recognize the man's face, though, from the photographs, and his voice, which had sounded gravelly on the phone.

He walked to the last door. The building was not quite silent; a radio or television played softly in one of the apartments, and in the other it sounded as if someone was practicing on a piano, tentatively, unsure of the notes. He hesitated out of old habit to listen for trouble sounds; the snick of a pistol slide being drawn back, sirens down on the street, boots on the stairs. The light filtering through the window was pale yellow, and his eyes were drawn to it like a moth to flame. The ceiling and walls angled inward to him, crushing his breath; he longed to escape to the clean air on the street.

There was someone inside the apartment who didn't belong there. He was hearing hard-soled shoes. At the Pivnoy they laughed and said that the old man always wore his bedroom slippers outside.

Nikolayev turned and went silently to the end of the hall, where he flattened himself in the corner next to the small window in the darker shadows. He hadn't brought a pistol.

The door opened, and two men came out. They were very large, their heads were shaved and they wore shiny leather jackets despite the heat. One of them carried a canvas satchel. Nikolayev's legs felt like straw. They closed the door, turned away and headed to the stairs. He watched the doorway until they were gone and he could no longer hear them on the stairs, wondering what he would have done had they turned around and seen him.

Zhuralev was part of the Baranov crowd. If anyone had the answers it would be him. Someone who had been there, someone who knew if the bridge still existed between then and now. He waited for a long time, thinking that he could walk away. The August heat seemed even more oppressive now.

He let himself into the overstuffed two-room apartment. Books and magazines and newspapers were strewn everywhere, but not as if the place had been searched. This was the way the man lived. The rooms were like a furnace, but filled with the odors of musty books, pipe tobacco and something else. Unpleasant. The hairs on the back of his neck bristled.

He went to the bedroom door. Gennadi Zhuralev, his blood-filled eyes open, lay on his back on the bed. He was fully clothed, carpet slippers on his feet, a silenced pistol in his slack hand. It had been made to look as if he had shot himself in the temple with the gun. But suicides did not usually go to the trouble of using a silenced pistol so that their neighbors would not be disturbed by the noise.

Nikolayev was conscious of his heart arrhythmia, a fluttering in his chest that made him dizzy and empty. With a feeling of deep despair he knew that he was utterly alone. He was an old man, and he valued his peace, but at what cost, he wondered, looking at Zhuralev's body. Lie down with the lions but don't expect to remain safe forever. He couldn't make his wife understand that; she loved the perks that his KGB colonel's rank brought them; food, apartment, dacha on the Istra, a car; until she bled to death on the surgeon's table. A simple gallbladder operation. But nothing was as simple as all that, not even in Moscow.
