Miss Rebecca Lane returns to her home village upon receiving word of her brother's worrisome behavior. Once she arrives, he pleads with her to go to nearby Swanford Abbey, a medieval monastery turned grand hotel that's rumored to be haunted. Since she feels responsible for her brother's desperate state, she reluctantly agrees to stay at the abbey until she can deliver his manuscript to a fellow guest who may help him to get published, an author who once betrayed them.
Before long, Rebecca starts seeing strange things, including a figure in a hooded black gown gliding silently through the abbey's cloisters at night. Even with all its renovations and veneer of luxury, the ancient foundations appear to echo with whispers of the past, including her own. That's where she encounters Sir Frederick, a former neighbor who long ago broker her heart. Now that he's a handsome widower of thirty-five, he's trying to overcome a past betrayal of his own.
Sir Frederick makes inquiries when the famous author is found dead and quickly finds out that several people held grudges against the author, including Miss Lane and her brother. As Sir Frederick seeks out answers, he's torn between his growing feelings for Rebecca and his pursuit of the truth. It seems Miss Lane is clearly hiding something.
