Nancy Mitford fans never have to wait too long before a new offering or interpretation comes along. The last few years have seen the 2021 BBC adaptation of Mitford’s 1945 novel The Pursuit of Love, starring Lily James, and the “Mitford Murders” series by Jessica Fellowes. There always seems to be another volume of collected letters, or a gorgeous edition, or a biography coming out; the most recent was Laura Thompson’s 2016 group study The Six. The latest, much-anticipated addition to the Mitford shelves is journalist India Knight’s Darling, a modern re-telling of The Pursuit of Love.
