As Maddy’s wedding day approaches, friends and family descend on the little town of New Bison, Michigan, to celebrate—so much so that Maddy wonders if there might be another happily-ever-after in store for her widowed father and innkeeper Mrs. Law. Unfortunately, she also has to deal with an unhappy couple: feuding cousins Hannah and Dorothy, who haven’t spoken in decades. Maddy can only hope the spectacular wedding cake crafted by her head baker doesn’t wind up as ammunition in a food fight.

But she doesn’t have to wait long for a wedding disaster to strike. When the imperious Dorothy crashes the rehearsal dinner—with several uninvited guests in tow—and starts battering everyone with constant complaints, the drama reaches reality-show levels. And the next day, Dorothy is dead . . . with Hannah standing over the body, bloody rolling pin in hand.

Nobody in town believes Miss Hannah could commit murder. But a detective newly relocated from New York doesn’t know the sweet, memory-challenged Hannah the way the locals do—and the evidence seems open-and-shut as an oven. Now, with her sous-sleuths the Baker Street Irregulars, the bride-to-be is busy digging into Dorothy’s past to catch a killer before she cuts the cake . . .
