Substitute Killer

During an outdoor outing, heavy rain forced everyone to gather at a country inn. That night, someone told a story in which a person died. The next day, the story came true: someone was dead. Which of the twin sisters had died? Was it an accident or murder? And who was the killer? A detective novel to die for.
