As part-time Tinker's Cove 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 marry the 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 . . .

Her 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. With tensions building, personalities clashing, and real dangers emerging at the chateau, Lucy will 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 . . .
