Aunt Dimity, the ghost with the flowing handwriting, returns for a fourth outing with her living partner, Lori Shepherd, in this fluffy village cozy. Now living in England, Lori and her lawyer husband, Bill Willis, have welcomed twin boys, swelling the mostly retired population of Finch. Living in the cottage left to Lori by her mother's close friend, Dimity Westwood, Lori is thankful for the arrival of the local and unmarried Francesca Sciaparelli to aid with the double joys of motherhood. In this corpseless tale, the mystery concerns a document stolen from the vicarage. Finch has become divided over the apparent Roman treasure trove discovered by archeologist Adrian Culver in a village field. An obscure 19th-century document, proving the find is a hoax, is the stolen item. Asked to resolve the dilemma, Lori, a rare book expert, is aided by Aunt Dimity who communicates with her ghostly handwriting in a special blue journal. Atherton produces a diverse cast of villagers, especially the formidable Peggy Kitchen, a veritable locomotive who is determined to chuck Culver and his archeological miscellany out of the schoolhouse before her well-planned Harvest Festival. Featuring Lori's cherubic twins, a number of stuffed animals and the triumph of true love, Atherton delivers pure cozy entertainment. Mystery Guild selection; author tour. (Mar.)
