Old bones - David Wishart

Laddish Marcus Corvinus is spending his time in ancient Tuscany, sampling wine and ogling local talent (under the beady eye of his lovely wife Perilla) when his stepfather is accused of murder. It doesn't take long for Marcus to get him off the hook, but finding the true culprit is rather trickier. As he pursues his investigation, Marcus uncovers a major wine-making fraud as well as a sorry tale of infidelity, treachery, deceit and betrayal. And when he uncovers the real murderer, the reason for the crime turns out to have its roots in myth and history.
