Old Bones (A Gideon Oliver Mystery)

Blurb

In the flood tides off Mont St. Michel, revered Resistance-hero Guillaume du Rocher is drowned. Already assembled at the Rocher estate to deal with family business, members of the Rocher clan instead read his will. The next day a partial skeleton is found in the cellar and Gideon Oliver, a physical anthropologist, is called to examine the bones. They are those of a young man who died 50 years prior and Gideon believes the deceased was tied to the Resistance movement. When Gideon is threatened, and Claude, Rocher's principal heir, is poisoned, Gideon begins to unravel a web of espionage, family deceit and murder, whose dramatic resolution lies in the secret held by the old bones. This taut thriller won the 1988 Edgar Award for best mystery novel.
