"Silence!" the man growled. The men sitting next to Austin pulled him back by the shoulders. A long-bladed knife pointed at his right eye. The cab accelerated at neck-snapping speed, exited from the traffic stream and plunged into a dark maze of narrow cobblestone lanes.

They headed away from the waterfront, skirting Karakoy and the police squads who monitored the official red-light district. Austin glanced longingly at the restaurant lights at the top of Galata Tower. Then the taxi was moving along the Istikal Caddesi, weaving in and out of traffic, past the nightclubs, movie theaters and unregulated brothels that lined the gaudy strip. The cab spun off the main drag and climbed a hill into Bozoglu, where all the old European embassies were housed during the Ottoman Empire, and executed a series of squealing turns.

The car stayed upright despite the protesting tires, which told Austin that the driver was a professional who knew the limits of his vehicle. There had been no attempt to blindfold Austin, and he wondered if this meant he had a one-way ticket to oblivion. As the car continued to hook left and right through the urban warren, he concluded that a blindfold was unnecessary; he didn't have a clue where he was.

The fact that they hadn't killed him offered slim solace. He knew instinctively that these men would not hesitate to use the weapons they had brandished in his face. After several minutes, during which the city lights faded to a glow, the car whipped down a darkened, garbage-strewn street and into an alley not much wider than the vehicle. Austin's companions hustled him from the taxi and stood him against a brick wall while they bound his hands behind his back with duct tape. Then they pushed him through a doorway along a dim hall and into the lobby of an old office building. Grime covered the marble floor. On one wall was a brass floor directory black with the patina of age. The smell of onions and the muffled cry of a baby indicated that the office building was being used for human habitation. Probably squatters, Austin surmised.

His escorts nudged Austin into an elevator and stood behind him. They were hulking men, as big or brawnier than Austin, who had never considered himself to be a pigmy. The space was cramped, and Austin stood with his face pressed against the cold wrought iron of the ornate gate. He guessed that the elevator must date back to the time of the sultans. He tried not to think of frayed and neglected cables as the elevator slowly jerked and rattled up to the third and last floor. The elevator was more nerve-wracking than the speeding car. The elevator cracked to a stop, and one of his escorts growled in his ear.

"Out!" He stepped into a dark hallway. One man grabbed the back of Austin's shirt in a bunch, used it to steer him for- ward and brake him to an abrupt stop. A door opened, and he was maneuvered inside. There was the odor of old paper and oil from long-ago business machines. He felt pressure upon his shoulders, then the edge of a chair bumped against the back of his knees. He sat down and squinted into the darkness. A spotlight flashed on, and Austin saw sunspots as the glare hit him in the face. He blinked like a suspect being given the third degree in an old gangster movie.

A voice speaking in English came from behind the spotlight.

"Welcome, Mr. Austin. Thank you for coming." Something about the voice sounded familiar, but he couldn't place it.

"It was an invitation I couldn't resist."

A dry chuckle issued from the darkness. "The years haven't changed you, have they?"

"Do I know you?" A memory clawed at the back of Austin's mind like a cat scratching softly at the door.

"I'm hurt that you don't remember me. I wanted to thank you in person for the lovely bouquet of flowers you sent to hasten my convalescence. I believe you signed the card with the name of John Doe."

Austin was stunned. "I'll be damned!" he said, with a curious mixture of delight and foreboding. "Ivan!"

THE SPOTLIGHT SNAPPED off and a portable table lamp came on, illuminating the face of a man in his forties. He had a broad forehead and high cheekbones and would have been handsome if not for the massive scar defacing his right cheek.

"Don't be alarmed, Mr. Austin," Petrov said. "I'm not the Phantom of the Opera."

Austin's mind flashed back fifteen years to the Barents Sea. He remembered the frigid waters penetrating his heated dry suit as he activated the timer on two hundred pounds of explosives. It was a miracle the Russian was still alive.

"Sorry about the booby trap, Ivan. Can't say I didn't warn you to stay clear."

"No apology necessary. Simply a misfortune of war." He paused, then said, "I've wondered something for long time. Suppose our places had been reversed. Would you have listened to a warning from me?"

After a moment's reflection, Austin said, "I might have assumed, like you, that the warning was a diversion. I'd like to think discretion would have won over valor, but I can't say for sure. It was a long time ago."

"Yes, it was a very long time ago." Petrov's lips widened in a sad smile. "Obviously, discretion did not rule over my youthful impatience. I was impetuous in those days. Don't worry; I bear you no animosity for the fruits of my own foolishness. I would have killed you long ago if I thought you were entirely to blame. As I said, c'est la guerre. In a sense you are as disfigured as I am, only you can't see the scars that cover your heart. The war made hard men out of both of us."

"I recall hearing that the Cold War is over. I have a suggestion. Why not ask your friends to give us a lift to the bar at the Palace Hotel? We can talk about old times over a drink."

"In time, Mr. Austin. In time. We have a matter of grave importance to discuss." Petrov's voice had gained a businesslike edge, and his eyes drilled into Austin's face. "I would like to know what you were doing at the abandoned Soviet submarine base on the Black Sea."

"Seems I was naive to think our brief visit went unnoticed."

"Not at all. It's a desolate part of the coast. Under normal circumstances, you could have landed a division of Marines without detection. We've kept the area under surveillance for months, but we were caught off guard. We know from intercepted radio messages that you landed some sort of air- craft and that the NUMA ship came in to pick you up. Please tell me what you were doing on Russian territory. Take your time. I'm in no hurry."

"I'll be glad to fill you in." Austin squirmed in his chair. "It might help my memory if I weren't sitting on my wrists. How about loosening the tape?"

Petrov thought briefly, then nodded. "I consider you a dangerous man, Mr. Austin. Please don't try anything foolish."

Petrov gave a sharp order in Russian. Someone came up from behind. Austin felt a cold blade against his wrists and the tape was severed in a single swipe.

"Now for your story, Mr. Austin."

Austin massaged the circulation back into his arms. "I was on the NUMA survey ship Argo, conducting a study of wave action in the Black Sea. Three American television people were supposed to rendezvous with our ship, but they had heard about the old sub base before they sailed from Istanbul, and decided to check it out without notifying us of their change in plans. They were overdue and I went looking for them. Some men on shore murdered a Turkish fisherman who was bringing the TV people to shore, and attempted to kill them, too."

"Tell me about these killers."
