Book Log 2019 #45: The Dark Vineyard by Martin Walker

An agricultural research station just outside of Saint-Denis burns, with suspicion turning to local environmentalists who oppose its work on GMO crops. While local police chief Bruno investigates that, he also has to deal with the public outcry over a California winery's plans to buy up as many local vineyards as they can to create a larger, more industrial vineyard.  While Bruno tries to handle both events with his trademark informal investigating, a couple of bodies turn up, increasing the pressure on him to get everything back to normal.

I really do enjoy this series. Bruno is an excellent character, and the descriptions of the Dordogne region will make you want to visit. Or move there for good.
