It's the 1950's in Santa Lucia, California, and the height of the social season. Time for the new Miss Santa Lucia, Nora Burbank, to display her loveliness at a high society fashion show produced by the city's own fashionistas--Margot and Daphne, owners of Poppy Cove, the most elegant and "in" little dress shop in the county. Nora steals the show in her designer gown and custom-made necklace created by local jeweler Isaac Mendelson, and used on the sly by his apprentice son-in-law, Efrem Goldberg. At the conclusion of the show, the young queen is allowed to keep her dress and a replica of the necklace for her own. But Monday morning, Efrem arrives in a panic at Poppy Cove to beg Margot and Daphne's assistance in tracking down the real necklace, which he believes was inadvertently switched for the replica backstage. The girls get involved in Efrem's dilemma and try to help him before Isaac's any the wiser. But before that can happen, Miss Santa Lucia is found dead in her bed and the necklace is missing. Who killed Nora Burbank? Is it someone jealous of her new royal position and all of its perks? Or did she just happen to be in the way when a thief attempted to steal her diamond-studded necklace? Did Nora have the real or the fake necklace, and how much did the thief and murderer know about it? But, of course, before the girls can find the killer, they'll have to create several beautiful ensembles, calm numerous irate clients, and flirt with their ever-so-attentive boyfriends, before solving this mystery.
