The Mitford Vanishing

The Mitford sisters, six eccentric socialites and political renegades in the interwar years in England, encountered a frightful number of murders in their day, at least as told in Fellowes’s glamorous historical series, now in its fifth installment. This time, Decca, second-youngest daughter of patriarchal Lord Redesdale and his long-suffering wife, Sydney Bowles, is missing. The family suspects that the 18-year-old has run off with her second cousin, Churchill’s nephew Esmond Romilly, to marry him and fight on the side of the anti-facists in the Spanish Civil War (which Decca and Esmond did in real life). Enter the Mitfords’ former maid Louisa and her husband, Guy, proprietors of the Cannon & Sullivan detective agency. Hired to look for Decca, Louisa nervously embraces the fledgling rights of women in 1937, using her maiden name for work and leaving the couple’s baby with sitters. Indeed, she’s far more advanced than the Mitford “girls,” whose blithely colonial ways color their every move. Fellowes’s at times very sad, often funny story stands out for its unusual, Spanish Civil War backdrop; it also offers pleasingly scathing treatment of Nazi sympathizers, exciting chases from England to Spain and back (repeatedly!), and an extraordinarily tense closing scene. While this works as a standalone, go back to the earlier books for a treat.
