“It would be deeply embarrassing if our ties to Solomon were ever exposed,” Shamron added. “And it would also make it more difficult for us to recruit sayanim from the Jewish communities around the world. We’re a small service. We can’t function without them.”

The sayanim were a worldwide network of volunteer Jewish helpers. They were the bankers who supplied Office agents with cash in emergencies; the doctors who treated them in secret when they were wounded; the hoteliers who gave them rooms under false names, and the rental-car agents who supplied them with untraceable vehicles. The vast majority of the sayanim had been recruited and nurtured by Shamron himself. He devotedly referred to them as the secret fruit of the Diaspora.

“It also has the potential to make a volatile situation in the Netherlands much worse,” Gabriel said. “Solomon Rosner was one of the most well-known critics of militant Islam in Europe. If it ever came out that he was our paid mouthpiece, the Jewish community in Holland might find itself at risk.”

“I disagree with your characterization,” said Shamron, “but your point is duly noted.”

“How am I supposed to get into Rosner’s office?”

It was Navot who answered. “About a year ago, when the threats against Rosner started coming fast and furious, we knew we had to make plans for just such a contingency. Rosner told his assistant, a young woman named Sophie Vanderhaus, that, in the event of his death, she would be contacted by a gentleman named Rudolf Heller and given a set of instructions she was to follow to the letter.”

Herr Rudolf Heller, venture capitalist for Zurich, was one of Shamron’s many false identities.

“I contacted Sophie last night,” Shamron said. “I told her that a colleague of mine would be arriving in Amsterdam tomorrow afternoon and that he was to be given complete access to all of Professor Rosner’s files.”

“Tomorrow afternoon?”

“There’s an El Al flight that leaves Ben-Gurion at six forty-five and arrives in Amsterdam at two. Sophie will meet you in front of the Café de Doelen at four.”

“It could take me days to go through all of Rosner’s files.”

“Yes,” Shamron said, as though he were glad the task had not been inflicted on him. “That’s why we’ve decided to send along some help. He’s already in Europe on a personal matter. He’ll be there when you arrive.”

Gabriel raised his coffee cup to his lips and eyed Shamron over the rim. “And what about the promises we made to the European security services? The covenant we signed in blood in exchange for getting them to drop all the charges and lawsuits against me?”

“You mean the covenant that forbids you from operating on European soil without first obtaining permission from the security service of the country involved?”

“Yes, that one.”
