I had read "The Pursuit of Love" & thoroughly enjoyed it so I got the complete novels, basically to read "Love in a Cold Climate" & see what the rest were like. "Love" was also very good & "Don't tell Alfred" was good if you liked the other two but not in the same class. I haven't read all the others yet but, while they are an enjoyable read & I am glad I have them, they are nothing particularly special. If you disapprove of the Mitfords & can't take their attitudes & lifestyle this not for you! ( Actually Nancy was caricaturing it while making the point that it wasn't all bad. )
I started reading this book by chance on holiday. I didn't think it was going to be my sort of book but It is a fascinating story brilliantly told. So I bought this copy for my wife who had the same opinion. It arrived within the stated time & was posted very quickly but Royal Mail quite a long time to deliver what is a slim volume. But do read it if you haven't.
