“Since when do Zurich venture capitalists employ professional surveillance men?” She set off down the Groenburgwal. “Come on, Herr Kiever . You have a long night ahead of you.”

Her original estimate of Rosner’s archives proved wildly optimistic. Gabriel, after conducting a brief tour of the canal house, reckoned the true number of pages ran closer to a quarter million. There were files in Rosner’s office and files in Sophie’s. Files lined the hallway, and there was a dank chamber filled with files in the cellar. And then, of course, there was all the material contained on the hard drive of Rosner’s computer. So much for Shamron’s prediction that they would be back in Jerusalem by the weekend.

They started in Rosner’s office and worked as a threesome. Gabriel and Lavon, the restorer and the archaeologist, sat side by side at Rosner’s desk, while Sophie placed the files before them one by one, providing a bit of background where appropriate, translating the odd passage when necessary. Files of interest or of a sensitive nature were separated out and packed into cardboard boxes for shipment to King Saul Boulevard. By nine o’clock they had filled four boxes and found not a single reference to Ari Shamron, Herr Rudolf Heller, or the Office. Rosner, it seemed, had been a careful asset. He also had been a meticulous researcher and collector of intelligence. Contained in the rooms of the old canal house on the Groenburgwal was a remarkably detailed and frightening portrait of the radical Islamic networks operating in Amsterdam and beyond.

By ten o’clock they were all famished. Unwilling to suspend work, they decided on takeaway. Gabriel voted for kebabs, Sophie for Indonesian, and Lavon for Thai. After ten minutes of spirited debate, they resorted to drawing a name from one of Rosner’s old felt hats. Sophie did the honors. “Thai,” she said, smiling at Lavon. “Shall we draw again to see who has to go pick it up?”

“I’ll go,” said Gabriel. “There’s someone I need to have a word with.”

A gentle snow was falling when Gabriel stepped outside five minutes later. He stood for a moment atop Rosner’s iron steps, buttoning his overcoat against the cold, while scanning the street for signs of surveillance. It was deserted except for a single bundled soul, perched on a public bench on the opposite bank of the canal. He wore a threadbare woolen overcoat and a black-and-white checkered kaffiyeh for a scarf. His gray beard was unkempt and atop his head was the white kufi skullcap of a devout Muslim. Gabriel descended the steps and walked to the drawbridge at the end of the street. As he turned into the Staalstraat, he could hear footfalls on the cobblestones behind him. He swiveled his head deliberately and took a long, highly unprofessional look over his shoulder. The Muslim man who had been seated on the bench was now thirty yards behind and walking in the same direction. Two minutes later, as Gabriel passed Rosner’s memorial outside Café de Doelen, he looked over his shoulder a second time and saw that the man with the kufi and the kaffiyeh had cut the distance between them in half. He thought of the words Lavon had spoken to him earlier that afternoon at the Hotel Europa. Just try not to kill anyone while we’re in Amsterdam , Lavon had said. Gabriel had no intention of killing the man. He just wanted answers to two simple questions. Why had a devout Muslim spent the better part of the evening sitting outside Solomon Rosner’s house? And why was he now following Gabriel through the dark streets of Amsterdam?

The restaurant where Sophie Vanderhaus had placed the takeaway order was in the Leidsestraat, not far from the Koningsplein. Gabriel, after crossing the Amstel, should have gone to the right. He went left instead, into a narrow pedestrian lane lined with sex shops, American fast-food restaurants, and tiny Middle Eastern cafés. It was crowded in spite of the hour; even so, Gabriel had no trouble keeping track of his pursuer in the garish neon light.

The street emptied into the Rembrandtplein, but twenty yards before the busy square Gabriel turned into a darkened shoulder-width alley that led back to the river. The man with the kaffiyeh and the kufi paused at the mouth of the alley, as though reluctant to enter, then followed after him.

Gabriel removed the Beretta from its resting place at the small of his back and chambered a round. As he did so, he could almost hear Shamron’s voice echoing in his head: We do not wave our guns around in public like gangsters and make idle threats. When we take out our weapons we do so for one reason and one reason only. We start shooting. And we keep shooting until the target is dead . He slipped the gun into the pocket of his overcoat and walked on.

At the midpoint of the alley, the darkness was nearly impenetrable. Gabriel turned into a bisecting passageway and waited there with his hand wrapped around the butt of the Beretta. As the bearded man came past, Gabriel stepped from the alley and delivered a knifelike blow to his left kidney. The man’s legs buckled instantly, but before he could crumple to the ground, Gabriel seized hold of the kaffiyeh and hurled him hard against a graffiti-spattered brick wall. The look in the man’s eyes was one of genuine terror. Gabriel struck him again, this time in the solar plexus. As the man doubled over, Gabriel quickly searched him for weapons but found only a billfold and a small copy of the Quran.

“What do you want with me?” Gabriel asked in rapid Arabic.

The man managed only a single, wet cough.

“Answer me,” Gabriel said, “or I’ll keep hitting you until you do.”

The man lifted his hand and pleaded with Gabriel not to strike him again. Gabriel let go of him and took a step back. The man leaned against the wall and fought for breath.

“Who are you?” Gabriel asked. “And why are you following me?”

“I’m the person you’re looking for in Solomon Rosner’s files,” he said. “And I’ve come to help you.”

AMSTERDAM

M y name is Ibrahim.”

“Ibrahim what?”

“Ibrahim Fawaz.”

“You were a fool to follow me like that, Ibrahim Fawaz.”

“Obviously.”

They were walking along the darkened embankment of the Amstel River. Ibrahim had one hand pressed to his kidney and the other wrapped around Gabriel’s arm for support. A gritty snow had begun to fall and the air was suddenly brittle with the cold. Gabriel pointed to an open café and suggested they talk there. “Men like me don’t have coffee in places like that, especially in the company of men like you. This is not America. This is Amsterdam.” He swiveled his head a few degrees and glanced at Gabriel out of the corner of his eye. “You speak Arabic like a Palestinian. I suppose the rumors about Professor Rosner were true.”

“What rumors?”

“That he was a pawn of the Zionists and their Jewish supporters in America. That he was an Israeli spy.”

“Who said things like that?”

“The angry boys,” said Ibrahim. “And the imams, too. They’re worse than the young hotheads. They come from the Middle East. From Saudi Arabia. They preach Wahhabi Islam. The imam in our mosque told us that Professor Rosner deserved to die for what he had written about Muslims and the Prophet. I warned him to go into hiding, but he refused. He was very stubborn.”

Ibrahim stopped and leaned against the balustrade overlooking the sluggish black river. Gabriel looked at the Arab’s right hand and saw it was missing the last two fingers.

“Are you going to be sick?”

“I don’t think so.”

“Can you walk, Ibrahim? It’s better if we walk.”

The Arab nodded and they set off slowly along the riverbank. “I suppose you were the professor’s handler? That’s why you and your friend are digging frantically through his files.”

“What I’m doing inside his house is no business of yours.”

“Just do me a favor,” the Arab said. “If you come across my name, please do me the courtesy of dropping the document in question into the nearest shredder. I respected Professor Rosner very much, but I don’t want to end up like him. There are men in Amsterdam who will slit my throat if they knew I was helping him.”

“How long did you work for him?”

“A long time,” said Ibrahim. “But it wasn’t work . We were partners, Professor Rosner and I. We shared the same beliefs. We both believed the jihadists were destroying my religion. We both knew that if they weren’t stopped, they would destroy Holland, too.”

“Why work for Rosner? Why not the police?”

“Perhaps you can tell from my accent that I am Egyptian by birth. When one comes from Egypt, one has a natural fear of the police, secret or otherwise. I’ve lived in Holland for twenty-five years now. I am a citizen of this country, as are my wife and son. But to the Dutch police, and the rest of my countrymen, I will always be an allochtoon . An alien.”

“But you must have guessed Rosner was passing along some of your information to the police and the Dutch security service.”

“And to the Israeli secret service as well-or so it appears.” He looked at Gabriel and managed a sage smile. “I must confess that Israelis are not terribly popular in my home. My wife is a Palestinian. She fled to Egypt with her family in 1948 after al-Nakba and settled in Cairo. I’ve heard about the suffering of the Palestinian people every night at my dinner table for thirty-five years now. My son drank it with his mother’s milk. He is Egyptian and Palestinian, a volatile mix.”

“Is this the reason you followed me tonight, Ibrahim-to engage in a debate about the Palestinian Diaspora and the crimes of Israel ’s founders?”

“Perhaps another time,” the Egyptian said. “Forgive me, my friend. Now that you are no longer striking me, I was just trying to make polite conversation. I was a professor in Egypt before I immigrated to Holland. My wife and son accuse me of being a professor still. They’ve spent their lives listening to me lecture. I’m afraid they no longer tolerate me. When I get a chance to teach, I take it.”

“You were a teacher in Holland, too?”

“In Holland?” He shook his head. “No, in Holland I was a tool. We decided to leave Egypt in 1982 because we thought our son would have more opportunities here in the West. I was an educated man, but my education was an Egyptian education and so it was worthless here. I built roads until I ruined my back, then I got a job sweeping the streets of Rotterdam. Eventually, when I could no longer even push a broom, I went to work in a furniture factory in west Amsterdam. The plant supervisor made us work fourteen hours a day. Late one night, when I was falling asleep on my feet, I made a mistake with the circular saw.” He lifted his ruined hand for Gabriel to see. “During my recuperation I decided to put my time to good use by learning to speak proper Dutch. When the factory manager heard what I was doing, he told me not to waste my time, because one day soon all the allochtoonen would be going home. He was wrong, of course.”
