Lavon gave Gabriel an elusive smile and lowered himself wearily into an armchair. Even Gabriel, who had known Lavon more than thirty years, sometimes found it hard to imagine that this fussy hypochondriacal little man was without question the finest street surveillance artist the Office had ever produced. They had worked together for the first time during the Wrath of God operation. Lavon, an archaeologist by training, had been an ayin, a tracker. When the unit disbanded, he had settled in Vienna and opened a small investigative bureau called Wartime Claims and Inquiries. Operating on a shoestring budget, he had managed to track down millions of dollars in looted Jewish assets and had played a significant role in prying a multibillion-dollar settlement from the banks of Switzerland. He had recently returned to Israel and was teaching biblical archaeology at Hebrew University. In his spare time he lectured on the fine art of physical surveillance at the Academy. No Office recruit ever made it into the field without first spending a few days with the great Eli Lavon.

“Your disguise is quite effective,” Lavon said with professional admiration. “For an instant even I didn’t recognize you.”

Gabriel looked at his reflection in the mirror over the dressing table. He wore a pair of black-framed eyeglasses, contact lenses that turned his green eyes to brown, and a false goatee that accentuated his already-narrow features.

“I would have added a bit more gray to your hair,” Lavon said.

“I have enough already,” Gabriel said. “How did you get roped into this affair?”

“Proximity, I suppose. I was at a conference in Prague delivering a lecture on our dig at Tel Megiddo. As I came off the stage my mobile phone was ringing. You’ll never guess who it was.”

“Trust me, Eli—I can guess.”

“I hear that voice, the voice of God with a murderous Polish accent, telling me to leave Prague for Amsterdam at once.” Lavon shook his head slowly. “Does Shamron really have nothing better to do at his age than worry about a dead sayan? He’s lucky to be alive. He should be enjoying his last few years on this earth, but instead he clings to the Office like a drowning man grasping at a life ring.”

“Rosner was his sayan,” Gabriel said. “And I’m sure he feels partly responsible for his death.”

“He could have let Uzi handle it. But he doesn’t fully trust Uzi, does he, Gabriel? The old man wanted you in Special Ops, not Uzi, and he’s never going to rest until you’re running the place.” Lavon pushed up the sleeve of his tweed jacket and looked at his watch. “Sophie Vanderhaus awaits us. Have you given much thought to how you’re going to play it with her?”

“She’s an intelligent woman. I suspect she already has a good idea about Herr Heller’s true affiliation—and why Rosner always met with him outside the country.”
