Mary's Mystery Bookshop is hosting a very special guest: beloved mystery author Addison Hartley. Hartley gives an intimate reading to the fans gathered in the store, but Mary's eyes are drawn not to the famous author but to a familiar face in the crowd. Could it be Mary's best friend from childhood, Claire Wilkes? As soon as Mary moves to greet her old friend, the woman disappears. When Mary reads Hartley's new novel, she finds eerie parallels to her own history. And when terrible rumors surface around town about a secret relationship between Claire and Marys husband John, Mary is more determined than ever to track down Claire.
