This is a novel that pokes fun at the wine business in the Napa Valley. The main character is an unemployed reporter who is doing duty as a PI trying to find out the origins of an unlabeled bottle of wine left with a prominent wine critic who gives it the top score (20 points) of any wine he has reviewed. Meanwhile, said wine critic accidentally kills himself in a wine vat at an industry party at a winery (the locals wonder if it was murder…). You can tell while reading it that the author knows his stuff and there are a lot of real people in the book, thinly disguised. A fun read.
