The problem with letters like these is that they contain many references to famous contemporary figures and events which are no longer famous. Having to refer constantly to footnotes becomes an irritating interruption, yet if the footnotes were not available more irritation would be felt.
However, there is enough of interest in these letters to make them well worth reading. Nancy Mitford had a light pen and an acerbic wit and from the early days when she was trying to escape from the Redesdale family to her final harrowing four years when she gallantly fought excruciating pain, lonelinees and despair there is not a dull page in this well-edited collection.
If you have any interest in this intriguing family, beg, borrrow or steal this book.
