Abby knows her arrest is just a case of mistaken identity. Mistaken because a young woman named Elizabeth Blume has just spent the last three weeks actively trying to "become" Abby in her own twisted way. Making things even more twisted for Abby is the fact that no one will believe her when she tries to point this out. Libby, as she is now asking to be called, started by trying to intern for her but since Abby remembered her as being trouble when she babysat for the Blumes, Abby decided not to open that can of worms again. Then Libby tries get closer to Marco, Abby's boyfriend, by hiring him to do some PI work on her behalf. When Abby shows up to her family's Friday night dinner and finds Libby in her seat, eating her Abby's favorite foods, Abby starts to feel a slow burn of anger. The next day, when Abby goes to her hair appointment and sees Libby sitting in the salon chair getting the exact same haircut as Abby has and then runs into her having lunch with her cousin, Abby decides enough is enough. Little does Abby know the best is yet to come. Libby opens 'Blume's Art Store' right across the square from Abby's flower shop 'Bloomers' and Abby seems to be the only person who can clearly see that Libby has attempted to exactly duplicate both the interior and exterior look of Abby's shop. When Delphi Blume is murdered and her body is left in the alley behind Bloomers, with witnesses seeing a woman who fits Abby's description to a "t," Abby is arrested.

Now Abby really needs to figure out whats going on with Libby and Libby's brother Oliver. How can she be the only one to see that these siblings are not quite right? Will she be able to prove who killed Delphi before everything in her life stops making sense?

This is the sixth Flower Shop Mystery. The familar characters and the complete resolution to the murder mystery is a strong part of what keeps fans coming back for more. It's also satisfying to read a book where the good are rewarded and the bad are punished.
