Follow the aroma of shamrock sugar cookies to the Beacon Bakeshop, a lighthouse on the shores of Lake Michigan where amateur sleuth Lindsey Bakewell is busy preparing for Beacon Harbor's St. Patrick's Day festivities - with a little help from her adorable Newfoundland, Wellington, of course!

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 as to clobber one with his walking stick. Now Lindsey will need more than the luck of the Irish to seize a golden opportunity to catch the real killer . . .
