The Chardonnay Charade by Ellen Crosby
My rating: 3 of 5 stars
If you are OK with the general premise of 'some person who has nothing to do with it gets herself mixed up in a murder investigation and despite having no actual skills or knowledge related to crime solving is able to find and confront the murderer before the police do' then this is a perfectly fine novel. I am finding that this model of mystery novel is irritating me (it didn't used to, but seems to be doing so now).
That said, the extensive information about the history of the Commonwealth of Virginia and the wine industry there was very interesting. The civil-war knowledge of random characters seems a bit over-the-top, but I have known people from VA who could spout civil war battle facts just like that. Apparently it is a regional characteristic.
