Summer can be the best of times or the worst of times for the resort town of Put-in-Bay on Lake Erie. For Bea Cartwright, business is booming as guests storm her B and B for the Bastille Day celebration. In honor of the holiday, the League of Literary Ladies is reading the Charles Dickens' classic, A Tale of Two Cities. It would be hard to make a more apropos selection, especially when they have their very own Defarge sisters, elderly twins Margaret and Alice, who run the local knitting shop. On Bastille Day, the head-banging rock band Guillotine shows their chops for the tourists, but the celebration is soon cut short. With something needling the Defarge dowagers and secrets that lead to murder, solving this mystery will be a far, far better thing than the Literary Ladies have done before. They'll just have to make sure to keep their heads while they try to stop a killer's reign of terror.
