He shook his head slowly. “It was madness, absolute madness. And now we are left with this. ISIS controls a swath of territory the size of the United Kingdom, right on the doorstep of Europe. Even Bin Laden would have never dared to dream of such a thing. And what does the American president tell us? ISIS is not Islamic. ISIS is the jayvee team.” He frowned. “What does this mean? Jayvee?”
“I think it has something to do with basketball.”
“And what does basketball have to do with a subject as serious as the rise of the caliphate?”
Gabriel only smiled.
“Does he truly believe this drivel, or is it an ignorantia affectata?”
“A willful ignorance?”
“Yes.”
“You’d have to ask him.”
“Do you know him?”
“We’ve met.”
Rousseau was obviously tempted to ask Gabriel about the circumstances of his one and only meeting with the American president, but he carried on with his lecture on ISIS instead. “The truth is,” he said, “ISIS is indeed Islamic. And it has more in common with Muhammad and his earliest followers—al salaf al salih—than some of the so-called experts care to admit. We are horrified when we read accounts of ISIS using crucifixion. We tell ourselves that these are the actions of barbarians, not men of faith. But ISIS doesn’t crucify only because it is cruel. It crucifies because, according to the Koran, crucifixion is one of the proscribed punishments for the enemies of Islam. It crucifies because it must. We civilized Westerners find this almost impossible to comprehend.”
“We don’t,” said Gabriel.
“That’s because you live in the region. You are a people of the region,” Rousseau added. “And you know full well what will happen if the likes of ISIS are ever let loose within the walls of your fortress. It will be . . .”
“A holocaust,” said Gabriel.
Rousseau nodded thoughtfully. Then he led Gabriel across the Pont Notre-Dame, to the Île de la Cité. “So in the words of Lenin,” he asked, “what is to be done?”
“I am merely a spy, Monsieur Rousseau, not a general or a prime minister.”
“And if you were?”
“I would tear them out root and branch. I would turn them into losers instead of winners. Take away the land,” Gabriel added, “and there can be no Islamic State. And if there is no state, the caliphate will recede once more into history.”
“Invasion didn’t work in Iraq or Afghanistan,” replied Rousseau, “and it won’t work in Syria. Better to chip away at them from the air and with the help of regional allies. In the meantime, contain the infection so it doesn’t spread to the rest of the Middle East and Europe.”
“It’s too late for that. The contagion is already here.”
They crossed another bridge, the Petit Pont, and entered the Latin Quarter. Rousseau knew it well. He walked now with a purpose other than his health, down the boulevard Saint-Germain, into a narrow side street, until finally he stopped outside the doorway of an apartment building. It was as familiar to Gabriel as the entrance of Hannah Weinberg’s building on the rue Pavée, though it had been many years since his last visit. He glanced at the intercom. Some of the names were still the same.
Presently, the door swung open and two people, a man and a woman in their mid-twenties, emerged. Rousseau caught the door before it could close and led Gabriel into the half-light of the foyer. A passageway gave onto the shadowed internal courtyard, where Rousseau paused for a second time and pointed toward a window on the uppermost floor.
“My wife and I lived right there. When she died I gave up the apartment and headed south. There were too many memories, too many ghosts.” He pointed toward a window overlooking the opposite side of the courtyard. “A former student of mine lived over there. She was quite brilliant. Quite radical, too, as were most of my students in those days. Her name,” he added, with a sidelong glance at Gabriel, “was Denise Jaubert.”
Gabriel stared without expression at Rousseau, as though the name meant nothing to him. In truth, he suspected he knew more about Denise Jaubert than did her former professor. She was indeed a radical. More important, she was the occasional lover of one Sabri al-Khalifa, leader of the Palestinian terror group Black September, mastermind of the Munich Olympics massacre.
“Late one afternoon,” Rousseau resumed, “I was working at my desk when I heard laughter in the courtyard. It was Denise. She was with a man. Black hair, pale skin, strikingly handsome. Walking
