Recently divorced and newly bereaved by her beloved mother's death, Lori Shepherd is scraping by as an office temp in Boston when she receives a letter from a Boston law firm informing her of the death in England of Miss Dimity Westwood. Lori is shocked because she had thought adventurous Dimity was her mother's fictional creation, the star of made-up bedtime stories.
Courtly lawyer William Willis and his attentive son Bill inform Lori that Dimity left instructions that she and Bill go to her Cotswolds cottage to prepare a collection of "Aunt Dimity" stories for publication. They find the cottage haunted by the ghost of Dimity, who blocks their efforts to trace the secret of her WW II romance with a gallant flier. That all ends happily comes as a surprise to none but Lori.
