Sour Puss — Rita Mae Brown

After an unexpected rekindling of their romance, Harry and her veterinarian ex-husband, Fair Haristeen, have happily remarried. But their nuptials are quickly overshadowed by the murder of a world-famous grape expert who was in town visiting the local vineyards. Residents of picturesque Crozet, Virginia, believe the deed was the work of an outsider--until a local is also found dead.

Having just planted a quarter acre of grapes herself, Harry's curiosity is naturally fueled--as is that of curious cats Mrs. Murphy and Pewter, along with corgi Tee Tucker. As the grapevines blossom, the furry entourage discovers the first critical clue. But can they show the humans what they've learned? And can they--or anyone--stop the killing?
