The Gilded Murder follows Matthew and Martha as they mingle with Newport high society in the summer of 1899 while setting out to enjoy the America's Cup Trials between Columbia and Defender. When Matthew runs into a group of fellow Civil War veterans, one of whom has become a multi-millionaire, they are invited aboard his yacht where one of them is viciously murdered. Under police suspicion themselves, Matthew and Martha must enlist several confederates to search for motives dating back to the war, and confront issues of their own as well, before uncovering the real killer. The Gilded Murder is the second installment of the Matthew and Martha Mystery series.
