"As the much-anticipated date approaches for the double wedding of Elizabeth to John and Mary to Bill, the Classen sisters are trying their best to get everything just right. While Martha deals with the picky wedding-cake baker, who just can't seem to make up her mind, the sisters receive a flurry of incoming mail. To their delight, most of it consists of congratulations and RSVPs for the wedding ceremony. However, one letter in a bright red envelope stands out ... an anonymous poison-pen letter demanding that the sisters vacate their home and store immediately. At first, the sisters think they are the sole targets of the letter writer, but as the days pass they soon discover they aren't the only ones in Bird-in-Hand who have been receiving hostile mail. In the flurry of trying to uncover the anonymous letter writer, old suspicions are raised and long-held grudges are unearthed. Can the Classen sisters solve their latest mystery before two of them say "I do"?"--publisher.
