“Pack up,” he said. “We’ll try again tomorrow.”

Martineau bid them good day and started toward the carpark. Yvette detached herself from the others and followed after him.

“How about dinner tonight?”

“I’d love to, but I’m afraid I can’t.”

“Why not?”

“Another dreary faculty reception,” Martineau said. “The dean has demanded my presence.”

“Tomorrow night?”

“Perhaps.” Martineau touched her hand. “See you in the morning.”

On the opposite side of the wall was a grassy carpark. Martineau’s new Mercedes sedan stood out from the battered cars and motor scooters of the volunteers and the less noteworthy archaeologists working on the dig. He climbed behind the wheel and set out along the D14 toward Aix. Fifteen minutes later he was pulling into a parking space outside his apartment house, just off the cours Mirabeau, in the heart of the city.

It was a fine, eighteenth-century house, with an iron balcony on each window and a door on the left side of the facade facing the street. Martineau removed his post from the mailbox, then rode the small lift up to the fourth floor. It emptied into a small vestibule with a marble floor. The pair of Roman water vessels that stood outside his door were real, though anyone who asked about their origin was told they were clever reproductions.

The apartment he entered seemed more suited to a member of the Aixois aristocracy than an archaeologist and part-time professor. Originally it had been two apartments, but Martineau, after the untimely accidental death of his widower neighbor, had won the right to combine them into a single flat. The living room was large and dramatic, with a high ceiling and large windows overlooking the street. The furnishings were Provençal in style, though less rustic than the pieces at his villa in Lacoste. On one wall was a landscape by Cézanne; on another a pair of sketches by Degas. A pair of remarkably intact Roman pillars flanked the entrance to a large study, which contained several hundred archaeological monographs and a remarkable collection of original field notes and manuscripts from some of the greatest minds in the history of the discipline. Martineau’s home was his sanctuary. He never invited colleagues here, only women-and lately only Yvette.

He showered quickly and changed into clean clothing. Two minutes later he was behind the wheel of the Mercedes once more, speeding along the cours Mirabeau. He did not drive toward the university. Instead, he made his way across the city and turned onto the A51 Autoroute toward Marseilles. He had lied to Yvette. It was not the first time.

MOST AIXOIS TENDED to turn up their nose at Marseilles. Paul Martineau had always been seduced by it. The port city the Greeks had called Massalia was now the second largest in France, and it remained the point of entry for the majority of immigrants to the country, most of whom now came from Algeria, Morocco, and Tunisia. Divided roughly in half by the thunderous boulevard de la Canebière, it had two distinct faces. South of the boulevard, on the edge of the old port, lay a pleasant French city with broad pedestrian walks, exclusive shopping streets, and esplanades dotted with outdoor cafés. But to the north were the districts known as Le Panier and the Quartier Belsunce. Here it was possible to walk the pavements and hear only Arabic. Foreigners and native Frenchmen, easy prey for street criminals, rarely strayed into the Arab neighborhoods after dark.

Paul Martineau had no such misgivings about his security. He left his Mercedes on the boulevard d’Anthènes, near the base of the steps that led to the St-Charles train station, and set out down the hill toward rue de la Canebière. Before reaching the thoroughfare he turned right, into a narrow street called the rue des Convalescents. Barely wide enough to accommodate a car, it sloped downward toward the port, into the heart of the Quartier Belsunce.

It was dark in the street, and Martineau, at his back, felt the first gusts of a mistral. The night air smelled of charcoal smoke and turmeric and faintly of honey. A pair of old men, seated on spindly chairs outside the doorway of a tenement house, shared a hubble-bubble water pipe and studied Martineau indifferently as he trod past. A moment later a soccer ball, deflated and nearly the color of the pavement, bounded toward him out of the darkness. Martineau put a foot on it and sent it adroitly back in the direction from which it came. It was scooped up by a sandaled boy, who, upon seeing the tall stranger in Western clothes, turned and vanished into the mouth of an alleyway. Martineau had a vision of himself, thirty years earlier. Charcoal smoke, turmeric, honey… For an instant he felt as though he was walking the streets of south Beirut.

He came to the intersection of two streets. On one corner was a shwarma stand, on another a tiny café that promised Cuisine Tunisienne. A trio of teenage boys eyed Martineau provocatively from the doorway of the café. In French he wished them good evening, then lowered his gaze and turned to the right.

The street was narrower than the rue des Convalescents, and most of the pavement was consumed by market stalls filled with cheap carpets and aluminum pots. At the other end was an Arab coffeehouse. Martineau went inside. At the back of the coffeehouse, near the toilet, was a narrow flight of unlit stairs. Martineau climbed slowly upward through the gloom. At the top was a door. As Martineau approached, it swung open suddenly. A man, clean-shaven and dressed in a galabia gown, stepped onto the landing.

“Maa-salaamah,” he said. Peace be upon you.

“As-salaam alaykum,” replied Martineau, as he slipped past the man and entered the apartment.

9 JERUSALEM

JERUSALEM IS QUITE LITERALLY A CITY ON A HILL. It stands high atop the Judean Mountains and is reached from the Coastal Plain by a staircase-like road that climbs through the twisting mountain gorge known as the Sha’ar Ha’Gai. Gabriel, like most Israelis, still referred to it by its Arab name, the Bab al-Wad. He lowered the window of his Office Skoda and rested his arm in the opening. The evening air, cool and soft and scented with cypress and pine, tugged at his shirtsleeve. He passed the rusted carcass of an armored personnel carrier, a memorial relic of the fighting in 1948, and thought of Sheikh Asad and his campaign to sever the lifeline to Jerusalem.

He switched on the radio, hoping to find a bit of music to take his mind off the case, but instead heard a bulletin that a suicide bomber had just struck a bus in the affluent Jerusalem neighborhood of Rehavia. He listened to the updates for a time; then, when the somber music began, he switched off the radio. Somber music meant fatalities. The more music, the higher the number of dead.

Highway One changed suddenly from a four-lane motorway into a broad urban boulevard, the famed Jaffa Road that ran from the northwest corner of Jerusalem to the walls of the Old City. Gabriel followed the road to the left, then down a long, gentle sweep, past the chaotic New Central Bus Station. In spite of the bombing, commuters streamed across the road toward the entrance. Most had no choice but to board their bus and hope that tonight the roulette ball didn’t land on their number.

He passed the entrance of the sprawling Makhane Yehuda Market. An Ethiopian girl in police uniform stood watch at a metal barricade, checking the bag of each person who entered. When Gabriel stopped for a traffic light, clusters of black-coated Haredi men drifted between the cars like swirling leaves.

A series of turns brought him to Narkiss Street. There were no parking spaces to be had, so he left the car around the corner and walked slowly back to his apartment beneath the protective awning of the eucalyptus trees. He had a bittersweet memory of Venice, of gliding home upon the silken waters of a canal and tying his boat to the dock at the back of his house.
