The Forsaken Inn by Anna Katharine Green audiobook.
Told from the perspective of a Mrs. Truax, the owner of an inn during the time of the American and French Revolutions, "The Forsaken Inn" is a locked-room mystery that keeps readers guessing about what has happened. A young couple stays at the inn for the night, and goes on their way in the morning ... and several years later, the bride's body is found in a secret room of the inn. Yet, many people saw that bride leave with her husband. How can this be?
Green tells her tale through Mrs. Truax' diary, and through letters and discussions with other characters who were friends of the young couple. An entertaining and highly recommended read.
