“The Gama’a and al-Jihad, of course, are with us still,” al-Zayyat said. “Their goal is to destroy the Mubarak regime, replace it with an Islamic republic, and then use Egypt as a base of operations to wage a global jihad against the West and Israel. Both groups are signatories of al-Qaeda’s declaration of war against the Crusaders and the Jews, and both are formally under the umbrella of Osama bin Laden’s command structure. Egyptians make up more than half of al-Qaeda’s core personnel, and they hold five of the nine positions in the ruling Shura Council. And, of course, Osama’s right-hand man is Ayman al-Zawahiri, the leader of al-Jihad.”

“So Egypt is no different than the Saudis,” Gabriel said. “You thought you could reach accommodation with the Islamic terrorists by giving them money and encouragement and deflecting their rage outward. And now they’re threatening to destroy you.”

“You did the same thing, my friend. Don’t forget that the Office and Shabak gave money and support to Hamas in the early days because you thought the Islamists were a good counterweight to the secular leftists of the PLO.”

“Point taken,” Gabriel said. “But please don’t tell me I’m supposed to pay you fifty thousand dollars to tell me that al-Qaeda is responsible for kidnapping the daughter of the American ambassador to London. I could have saved my money and just turned on CNN instead. They have lots of experts saying the same thing.”

“It’s not just al-Qaeda,” al-Zayyat said. “It’s a joint operation, a merging of assets, if you will.”

“Who’s the other partner?”

The Egyptian walked over to the drinks cabinet and refilled his glass. “There were other groups besides the Gama’a and al-Jihad that formed in the seventies. More than fifty in all. Some were just cells of university students that couldn’t organize a bucket brigade. Others were good. Very good.” He took a drink of the whisky. “Unfortunately, a group that sprang up at the University of Minya was one of the good ones. They called themselves the Sword of Allah.”

The Sword of Allah… Gabriel knew the name, of course. Anyone who worked in the field of Islamic terrorism did. In the late 1970s, after Sadat’s historic visit to Jerusalem, a group of university students, professors, and civil servants from the Upper Egyptian town of Minya had coalesced around a fiery Islamist cleric named Sheikh Tayyib Abdul-Razzaq. Sheikh Tayyib adopted a simple program for seizing power in Egypt: inflict as much terror and bloodshed on Egyptian society as possible and the regime would collapse under its own weight. In the early 1990s, he nearly succeeded. Flushed with the prospects of success, the sheikh decided to take his campaign global, long before there was such a thing known as al-Qaeda. He sent emissaries to Europe to open branch offices of the Sword among the burgeoning Muslim communities there and dispatched his older brother and closest advisor, Sheikh Abdullah Abdul-Razzaq, to suburban Washington to wage jihad against the most important patron of the Egyptian regime: the government of the United States. In 1998, Sheikh Abdullah was found guilty on charges of conspiring to bomb the State Department, the Capitol, and the headquarters of the FBI and was sentenced to life in prison. He had recently been diagnosed with cancer. Freeing the sheikh before his death was now one of the Sword’s top priorities.

“Al-Qaeda has been itching to hit London again for a long time,” al-Zayyat said. “And, of course, Sheikh Tayyib wants to get his brother back from the Americans. They decided to merge the two priorities into a single terror spectacular. Al-Qaeda handled the bombings, while the Sword and its European networks saw to the hostage-taking side of the operation.”

“What evidence do you have of Sword involvement?”

“You had the proof in your own hands for a few seconds in Hyde Park,” the Egyptian said. “Samir al-Masri, former student of engineering at the University of Minya, is a member of the Sword of Allah and one of its more talented terrorist operatives.”

“It would have been helpful, Wazir, if you’d told the Dutch he was living quietly in west Amsterdam.”

“We didn’t know he was in Holland or we would have.” The Egyptian sat down on the couch next to his bag of money. “Samir left Egypt a few months after the Americans went into Iraq. When the insurgency started up, he joined forces with Abu Musab al-Zarqawi and perfected his craft. Apparently he slipped out of Iraq shortly before Zarqawi’s death and made his way to Europe via Damascus. If you want to blame anyone for the fact that Samir was living quietly in west Amsterdam, blame the Syrians. And the Dutch, of course. Christ, they’ll let anyone into their country.”

“What else do you have besides Samir’s connection?”

“The al-Hijrah Mosque.”

“What about it?”

“The imam there is a graduate of al-Azhar in Cairo and a member of the Sword of Allah.”

“That’s still not enough.”

“This discussion is academic,” al-Zayyat said. “In twenty-four hours you’ll have proof the Sword of Allah is behind this. That’s when they’ll offer to trade Elizabeth Halton for Sheikh Abdullah.”

“How can you be so sure about the timing?”

“The Sword has carried out a number of kidnappings inside Egypt. Most of the time the outside world doesn’t even hear about them. Their method of operation is always the same. They wait one week before making demands. And if they set a deadline for killing the girl, they’ll do it when the second hand reaches twelve. And there won’t be any extensions or delays.”

“The Americans will never release Sheikh Abdullah.”

“If they don’t, the Sword of Allah and al-Qaeda are going to send the American president’s goddaughter home in a bag-or what’s left of her, I should say. They’ll kill her the same way they took her. With a great deal of bloodshed.”

“Have you told the Americans about any of this?”

Al-Zayyat shook his head.

“Why not?”

“Orders from on high,” said al-Zayyat. “Our fearless leader is afraid his patrons in Washington will be angry when they find out the plot to kidnap the ambassador’s daughter originated in Egypt. He’s trying to delay the day of reckoning as long as possible. In the meantime, he’s directed the SSI and the other security services to gather as much intelligence as possible.”

“Who’s the mastermind?”

“If I had to guess, it goes all the way to the top.”

“Zawahiri?”

The Egyptian nodded.

“But surely there’s someone between him and the operatives,” Gabriel said. “Someone like Khaled Sheikh Mohammad. Someone who made the trains run on time.”

“There is.” Al-Zayyat held his tumbler of whisky up to the sunlight and contemplated its color for a moment without speaking. “And if I had to venture a guess as to his identity, I’d say it’s almost certainly the work of the Sphinx.”

“Who’s the Sphinx?”

“We’re not sure who he is, but we know his handiwork all too well. All told, he’s killed more than a thousand people inside Egypt -tourists, government ministers, wealthy friends of the regime. We assume he’s highly educated and very well connected. We believe he has agents of influence and spies at the highest level of Egyptian society and government, including inside my service. He operates through cutouts like Samir. We’ve never been able to get close to him.”

“Could he have planned something like this from Egypt?”

“Highly unlikely,” al-Zayyat said. “He’s probably in Europe. In fact, I’d be willing to wager a fair amount of money that he is. The Sword has been very quiet in Egypt for the last year. Now we know why.”

“Where’s Sheikh Tayyib?”

“The same place he’s been for the last fifteen years: underground. He moves between a string of hideouts in Upper Egypt and the oasis towns of the Western Desert. We also think he moves in and out of Libya and the Sudan.”

“Find him,” Gabriel said.

“Elizabeth Halton will be dead long before we ever find the sheikh.”

“Start rounding up Sword operatives and bringing them in for quiet chats. That’s your specialty, isn’t it, Wazir? Quiet chats with Islamic extremists?”

“Let he who is without sin cast the first stone,” al-Zayyat replied. “Trust me, Allon, we’re kicking down doors as we speak, but the Sphinx knew we would. No one in Egypt knows where the girl is. I doubt even Sheikh Tayyib knows the operational details. Your best chance at finding her alive died with Samir al-Masri. The Sword is good at hiding people.”

“Someone knows,” Gabriel said. “Someone has to know.”

“The Sphinx knows. Find the Sphinx and you’ll find the girl.” The Egyptian put his hand on the grip of the briefcase. “So have I earned my fifty thousand yet?”

“I want everything you have on the Sword of Allah,” Gabriel said. “Case files, membership rolls, known front organizations in Europe. Names, addresses, telephone numbers.”

“It’s in a suitcase in the trunk of my car,” the Egyptian said. “But it’s going to cost you.”

Gabriel sighed. “How much, Wazir?”

“Another fifty thousand.”

“I don’t happen to have another fifty thousand on me.”

The Egyptian smiled. “I’ll take an IOU,” he said. “I know you’re good for it.”

The Samsonite suitcase that Wazir al-Zayyat produced from the trunk of his rented Volkswagen contained the lifeblood of one of the world’s most violent terror organizations and was therefore a steal at fifty thousand. When the Egyptian was gone, Gabriel opened a directory of known Sword members and started reading. Five minutes later he came across a name that was familiar to him. He located a photocopy of the corresponding file and examined the photograph. It was dated and of poor quality; even so, Gabriel could tell it was the same man he had encountered a week earlier in Amsterdam. I’m the person you’re looking for in Solomon Rosner’s files , the man had said to him that night. And I’ve come to help you .

T he knock was cautious and contrite. Dr. Yusuf Ramadan, professor of Near Eastern history at American University in Cairo, looked up from his work and saw a woman standing in the doorway of his office. Like all female employees of the Institute of Islamic Studies, she was veiled. Even so, the professor averted his eyes slightly as she spoke.
