During Sawrey's annual summer fette, Miss Beatrix Potter receives an unexpected visitor in the form of Baby Flora, left in a basket on her doorstep with a note, a sprig of hawthorn, and a scarab ring. All Beatrix knows about Flora's previous guardian is that she was a gray-haired woman, capable of scaling a brick wall in seconds. An investigation reveals that the ring was pawned and reclaimed in Sawrey by a resident of Hawthorn House. The legendary manor is supposed to be vacant-and rumored to be haunted. Now Beatrix and her animal friends are left pondering the possible involvement of fairy folk in these utterly puzzling happenings.
