Disconcerting ... 1

Hello. Contrary to previous opinion, I am addicted books PD James. I do not know if this is so that I have not hooked up with this title, which detonates in the series of the author's books.
First, it may not be necessary to know the Jane Austen novel to read this book, but it should help, because there are so many characters that gets lost. Secondly, as this is PD James, there is murder. But I did not see the point of this story. No doubt there was there interest in knowledge of manners and society of that time. And yet, I appreciate this author at the highest point. There is murder, but no real investigation, the main people indulge their feelings about the murder. One culprit is appointed from the start, tried, convicted, and nothing really happens, and the reality is revealed by the arrival of a letter that puts things in their place. The characters in bizarre behavior are explained, but ... Then everything falls into place, and life goes on as before.
Of course, this is a very personal opinion, but I really do not see the point of this book. Perhaps that will enthrall fans of Jane Austen. But I'm waiting to find PD James in the further adventures of Commander Dalgliesh, to be sure, this time, to find my account. Thank you
