Every couple has their secrets... It's wedding season on Nantucket. The beautiful island is overrun with summer people - an annual source of aggravation for year-round residents. And that's not the only tension brewing offshore. When one lavish wedding ends in disaster before it can even begin - with the bride-to-be discovered dead in Nantucket Harbor just hours before the ceremony - everyone in the wedding party is suddenly a suspect. As Chief of Police Ed Kapenash digs into the best man, the maid of honor, the groom's famous mystery novelist mother, and even a member of his own family, the chief discovers that every wedding is a minefield - and that no couple is perfect.
