Dying on the Vine Hardback - 2012

"Edgar(r) Award winning author Aaron Elkins s creation forensics professor Gideon Oliver has been hailed by the "Chicago Tribune "as a likable, down-to-earth, cerebral sleuth. Now, the celebrated Skeleton Detective is visiting friends at a vineyard in Tuscany when murder leaves a bitter aftertaste

The likely motive: his discovery that Nola had been having an affair.
Not long afterwards, Gideon Oliver and his wife, Julie, are in Tuscany visiting their friends, the Cubbiddu offspring. The renowned Skeleton Detective is asked to reexamine the bones.

Whatever it was that happened in the mountains, a murder-suicide it was not.
Soon Gideon finds himself in a morass of family antipathies, conflicts, and mistrust, to say nothing of the local carabinieri s resentment. And when yet another Cubbiddu relation meets an unlikely end, it becomes bone-chillingly clear that the killer is far from finished "
