It's Christmas in Caerphilly, and chaos is in full swing. Two of Meg's cousins-- bitter rivals since childhood-- are both holding their destination weddings in the same town, on the same day, and even in the same venues. As tempers flare between the brides and their mothers, Meg steps in to keep the peace. But her holiday juggling act takes a dark turn when she discovers the wedding photographer's murdered body. With a long list of suspects-- from scorned bridesmaids to humiliated guests-- Meg must help the police uncover the killer before the double wedding turns into a double disaster. And if the culprit turns out to be one of the soon-to-be newlyweds, Meg will have to unmask them before anyone can say, "speak now or forever hold your peace".
