The Otis-Winbury wedding promises to be an event to remember: the groom's wealthy parents have spared no expense to host a lavish ceremony at their oceanfront estate. But it's going to be memorable for all the wrong reasons after tragedy strikes: a body is discovered in Nantucket Harbor just hours before the ceremony --- and everyone in the wedding party is suddenly a suspect. As Chief of Police Ed Kapenash interviews the bride, the groom, the groom's famous mystery-novelist mother, and even a member of his own family, he discovers that every wedding is a minefield --- and no couple is perfect.
