Heleen was squat and boxy, painted chocolate brown and trimmed in red. Flower boxes lined her gunwales, and a skiff with an outboard motor bobbed at her stern. Her interior had been recently renovated; stainless-steel appliances shone in the small but sophisticated kitchen, and Scandinavian-style furniture adorned the comfortable sitting room. Three modern paintings of questionable taste had been removed from the walls and in their place hung a large-scale map of Amsterdam and several dozen surveillance photographs of a Muslim man of late middle age. A notebook computer with secure communications software stood on the glass dining-room table, and before it sat a small figure who seemed to be wearing all of his clothing at once. Gabriel pleaded with him to extinguish his cigarette. The overnight drive from Paris had left him with a splitting headache.

“If Ibrahim Fawaz is a terrorist, he certainly doesn’t act like one,” Eli Lavon said. “He doesn’t engage in anything that might be construed as a rudimentary countersurveillance, and his movements are predictable and direct.”

Gabriel looked up at the map of Amsterdam on the wall, where Ibrahim’s daily routine was represented by a thick red line. It ran from his apartment in the August Allebéplein to the West Amsterdam Islamic Community Center, then to the Ten Kate Market, and finally to the al-Hijrah Mosque. Times of arrival and departure were meticulously noted and supported by photographic evidence.

“Where?” Gabriel asked. “Where should we take him?”

Lavon stood and walked over to the map. “In my learned opinion, there’s only one spot that’s suitable. Here”—he stabbed the map twice with his stubby forefinger—“at the end of the Jan Hazenstraat. He walks by there on the way home from evening prayers at the mosque. It’s reasonably quiet for Amsterdam, and if we can take out the streetlamps he’ll never see us coming.” He turned and looked at Gabriel. “When are you thinking about doing it?”

The answer came from the kitchen, where Sarah was making a fresh pot of coffee. “Tonight,” she said. “We have no choice but to take him tonight and start the interrogation.”

“Tonight?” Lavon looked at Gabriel and gave him an incredulous smile. “A year ago I was teaching this child how to walk the street like a professional. Now she is telling me that I have to kidnap a man from a densely populated European city after watching him for less than forty-eight hours.”

“Unfortunately, the child is right, Eli. We have to do it tonight and get started.”

Lavon sat down again and folded his arms. “Do you remember how long I watched Zwaiter in Rome before we even began talking about how to kill him? Three weeks. And that was for an assassination, not a kidnapping. And you know what Shamron always says about kidnap operations.”
