In need of some quick dough, full-time baker and sometime sleuth Sally Muccio decides to rent the vacant apartment over the bakery to a friend of her grandmother's. Allegra Fiato is nothing like Sal's darling Grandma Rosa, though. She's mean, dishonest, and harboring a deadly secret.
When the elderly woman is mowed down in a hit and run, it quickly becomes obvious this was no accident. Grandma Rosa asks for Sal's help to find the killer which involves a last minute trip to Vegas crashed by Sal's crazy parents, stolen fortune cookies, and a mysterious missing locket. To add more spice to the mix, a loved one makes a startling admission to Sal that shocks her to the very core. Suddenly, Sal's world is in danger of crumbling around her. Can she put the pieces back together in time before the killer makes her the next victim?
