Gastronomical dream team sisters Bernadette and Libby Simmons, owners of A Little Taste of Heaven Catering, are thrust into a Celtic knot of malice and mayhem when a special St. Patrick's Day celebration goes awry. For most people in town, St. Paddy's Day means good food, great music, and plenty of Guinness. But when Mike Sweeney's body is discovered floating atop a vat of green beer, the celebrating comes to an abrupt end.
The prime suspect is the Simmons sisters' best customer, Bree Nottingham, but Bernie and Libby don't think so. What about Bree's brother, who is known for his hot temper and love of drink? Then there's the Corned Beef and Cabbage Club, a group with more buried history than the Emerald Isle itself. Every one of them has a motive to sing Sweeney his last Irish lullaby.
The situation is boiling over and if Bernie and Libby don't figure out what really happened to Sweeney soon, the killer could strike again.
