The Mitford Vanishing

1937. War with Germany is dawning, and a civil war already raging in Spain. Split across political lines, the six Mitford sisters are more divided than ever. Meanwhile their former maid Louisa Cannon is now a private detective, working with her ex-policeman husband Guy Sullivan.
Louisa and Guy are surprised when a call comes in from novelist Nancy Mitford requesting that they look into the disappearance of her Communist sister Jessica, nicknamed Decca. It quickly becomes clear that Decca may have made for the war in Spain - and not alone.
As a second, separate missing person case is opened, Louisa and Guy discover that every marriage has its secrets - but some are more deadly than others . . .
