ETIQUETTE FOR LOVERS AND KILLERS

Novel. It's 1964 in Eastport, Maine, and Billie is bored to death. That is, until an engagement ring and cryptic love letter turn up, addressed to "Gertrude." Until she meets yacht-club handsome Avery. Until the visits from a man in a fedora begin. Until she's one of the last people to see Gertrude alive, and the first to see her dead.
