Delightfully quirky Aunt Dimity series in fine style as a poison pen infiltrates a house party at the country estate of a British earl. When her best friend learns that her husband is heir to both an earldom and a fortune, Lori Shepard agrees to accompany a decidedly nervous Emma Harris to Hailesham Park to meet her in-laws. Of course, Lori enlists the help of her "Aunt Dimity," a blithe spirit who reveals her thoughts and opinions to Lori via the seemingly blank pages of a treasured journal. When one of the guests begins receiving threatening letters, it is up to the irrepressible Lori and her phantom sidekick to unravel a tangled family history in order to expose a twisted motive for mayhem.
