I'm sorry that some readers so disliked this book, and published really savage reviews. I loved it, and one of the reasons, to be honest, is that I also love John Le Carre, and was very moved by the quotations as well as the whole spy theme. I have also seen, and experienced, sexism in institutions. Perhaps some of the readers are just too young.
Which really brings up the issue of what is fair criticism. Sometimes I read books but realize that the insights and underpinnings of the story are very far from my understanding of reality. But I would never publish a review of a book I can't like for those reasons. I don't think it's fair, and I wouldn't want to discourage people from reading who could enjoy that kind of world view.
If you are widely read, if you love Hardy and the story of Demeter, I think you'll love this book.
