For anyone not acquainted with Donna Leon's novels, her genre is detective fiction, set in Venice, Italy and 'starring' Commissario Guido Brunetti.
The story lines don't however follow the conventional line of the detective novel, the endings can be surprising, and outwitting the upper echelon an office sport. On the way she introduces snippets of life in Venice, Italy in general, and references to food. My favourite so far in the food line is a pumpkin risotto that has slivers of ginger introduced. Lots of quotable quotes. . . leaving no stone unturned or feather unruffled - you get the idea!
