From Agatha and Edgar Award nominated author Valerie Burns, influencer-turned-bakery-owner Maddy Montgomery has sold plenty of wedding cakes before, but before she turns one out for her and her fiancé’s wedding, she’ll have to solve a little case of murder first …

Aunt Octavia would be so proud! Maddy has turned Baby Cakes Bakery—named for her 250-pound English Mastiff, Baby—into a runaway success, and she’s marrying the love of her life, veterinarian Michael Portman. #DreamWedding! Plus the timing couldn’t be better: the country’s biggest bridal expo has come to New Bison, Michigan, and Maddy has secured a spot for Baby Cakes to showcase their cakes. She’s also entered a contest for an all-expenses-paid wedding extravaganza offered by world-renowned wedding planner Serafina.

Unfortunately, supremely nasty Serafina truly takes the cake—she makes the worst bridezilla seem like a shy flower girl. But there’s one thing the wedding planner didn’t plan on—being impaled by one of the skewers Baby Cakes uses on their tiered wedding cakes.

While Maid of Honor Sheriff April Johnson rounds up suspects at the expo, Maddy and her aunt’s friends, the Baker Street Irregulars, and even Baby join forces to unveil a killer hiding in plain sight … before wedding bells start to chime.
