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.
