As part-time Tinker's Cove, Maine reporter Lucy Stone says "oui" to her daughter's surprise wedding invitation in France, she must also make a different kind of vow--to catch a killer!

When Lucy Stone arrives at a sprawling French chateau with the whole family, it should be the trip of a lifetime--especially because she's about to watch her oldest daughter, Elizabeth, marry the handsome, successful man of her dreams. But while navigating the vast countryside estate owned by her impenetrably wealthy in-laws-to-be, the jet-lagged mother of the bride has a creeping feeling that Elizabeth's fairytale nuptials to Jean-Luc Schoen-Rene are destined to become a nightmare . . .

Maternal instincts are validated the moment a body is pulled from a centuries-old moat on the property. A young woman has dropped dead under mysterious circumstances--possibly at the hands of someone at the chateau--and unflattering rumors about the Schoen-Rene line and their inner circle flow like champagne. Then there's the matter of Elizabeth's hunky ex beau showing up on the scene as she prepares to walk down the aisle . . .

With tensions building, personalities clashing, and real dangers emerging at the chateau, Lucy is determined to protect her family, together for the first time in years, and expose the one responsible. She'll have to locate the culprit among a list of worldly jilted lovers and potential criminal masterminds, or Elizabeth's trip down the aisle could end in tragedy . . .
