The woman in blue

Ruth's friend, Cathbad, is housesitting in Walsingham, a Norfolk village famous as a centre for pilgrimages to the Virgin Mary. One night, Cathbad sees a strange vision in the graveyard beside the cottage: a young woman dressed in blue. Cathbad thinks that he may have seen the Madonna herself, but the next morning the woman's body, dressed in a white nightdress and blue dressing gown, is found in a ditch outside Walsingham.
