The Man Who Didn't Burn by Ian Moore

When an English expat is brutally murdered, his charred corpse left on a Loire Valley hillside, the police turn to juge d’instruction Matthieu Lombard to find the killer.

Instead, Lombard discovers a wealth of secrets, grudges and feuds in the idyllic town of Saint-Genèse-sur-Loire. He begins to suspect that the remaining members of the Comité des Fêtes know more about the death than they are letting on.

But rather than towards an arrest, each clue he uncovers seems to point in one, unexpected direction: Joan of Arc. Is the answer to the murder hiding in the barroom gossip of the Lion d’Or? Or in another century altogether?
