I'm two chapters in to part three. It's unexpected and deeply pleasing. We leave the "Pride and Prejudice" timeline and go back in to the past lives of the servants: Mrs Hill's early service at Longbourne and James service in the war in Spain and Portugal.
The writing is vivid and intimate and full of things Jane Austen would have known little or nothing of.
This book is standing on its own feet now and doing it well.
