This was more complicated than book 1 in my opinion, as it followed not only a case of the stolen necklace, but a long ago wrong that was done to one of Nonna Maria's friends.
When a necklace is allegedly stolen from a hotel room, and one of Nonna Maria's relatives is accused, Nonna steps in to help the police. Nonna questions whether a necklace ever existed. Additionally, a body is found in the roadway, but it isn't a car crash that killed the woman, but something worse. Nonna investigates this, as well, and uncovers some ugly secrets that the powerful in the town sought to conceal.
I hope there is a book 3, because the ending is a bit of a teaser!
