Murder at the Blarney Bash (Beacon Bakeshop Mystery 5)

The latest installment in Darci Hannah's delicious Beacon Bakeshop Mystery series set in small-town Beacon Harbor, Michigan, featuring a baker heroine who lives in the local lighthouse with her beloved Newfoundland dog, Wellington.
Lindsey is baking up a storm—shamrock sugar cookies, Guinness chocolate cupcakes, Irish soda bread—for the well-timed grand opening of the Irish import gift shop, the Blarney Stone, owned by her boyfriend's uncle, Finnigan O'Connor, recently relocated from the Emerald Isle.
But it's Uncle Finn himself who seems full of blarney when he gleefully reveals a pot of real gold he claims he stole from an actual leprechaun. And Finn's fortune takes a turn for the worse when he's arrested for the bludgeoning of a small unidentified man dressed as a leprechaun—the murder weapon alleged to be his now-missing shillelagh.
Eccentric Uncle Finn may enjoy believing he's outwitted a leprechaun, but he would never be so deluded...
