The Champagne Conspiracy by Ellen Crosby

 Still working my way through the Ellen Crosby "vineyard" novels totally out of order.

In the Champagne Conspiracies, someone from Quinn's past pops up at the vineyard trying to protect his family's reputation. Lucie starts checking into that family's history and finds more than she bargained for. There is a murder, some deceit, an attempted murder and a roaring 20s party. A little something for everyone. I am really enjoying this series. I finally found the first book at the library, so will try to read some of the early books, now that I've read the more recent ones.
