Officially, Martineau was an adjunct professor of archaeology at the prestigious University of Aix-Marseille III, though he spent most of his time in the field and served as an adviser to more than a dozen local archaeological museums scattered across the south of France. He was an expert on the pre-Roman history of Provence, and although only thirty-five, was regarded as one of the finest French archaeologists of his generation. His last paper, a treatment on the demise of Ligurian hegemony in Provence, had been declared the standard academic work on the subject. Currently he was in negotiation with a French publisher for a mass-market work on the ancient history of the region.

His success, his women, and rumors of wealth had made him the source of considerable professional resentment and gossip. Martineau, though hardly talkative about his personal life, had never made a secret of his provenance. His late father, Henri Martineau, had dabbled in business and diplomacy and failed spectacularly at both. Martineau, upon the death of his mother, had sold the family’s large home in Avignon, along with a second property in the rural Vaucluse. He had been living comfortably on the proceeds ever since. He had a large flat near the university in Aix, a comfortable villa in the Lubéron village of Lacoste, and a small pied-à-terre in Montmartre in Paris. When asked why he had chosen archaeology, he would reply that he was fascinated by the question of why civilizations came and went and what brought about their demise. Others sensed in him a certain restiveness, a quiet fury that seemed to be calmed, at least temporarily, by physically plunging his hands into the past.

Martineau followed the girl through the maze of excavation trenches. Located atop a mount overlooking the broad plain of the Chaine de l’Étoile, the site was an oppidum, or walled hill fort, built by the powerful Celto-Ligurian tribe known as the Salyes. Initial excavations had concluded that the fort contained two distinct sections, one for a Celtic aristocracy and another for what was thought to be a Ligurian underclass. But Martineau had put forward a new theory. The hasty addition of the poorer section of the fort had coincided with a round of fighting between the Ligurians and the Greeks near Marseilles. On this dig, Martineau had proven conclusively that the annex had been the equivalent of an Iron Age refugee camp.
