Miss Beatrix Potter has returned to Near Sawrey, seeking refuge from the bluster of London in the quiet of a mild March. But it is 1912 and elsewhere in England Winston Churchill is said to be preparing for the possibility of war. At the same time, Beatrix's friend Grace Lythecoe has been receiving anonymous letters, threatening her good name and her plans to marry. Beatrix must investigate quietly so as not to arouse village gossip. There is also the matter of Beatrix's own romantic future - as she's offered a second chance at love.
