Reconstructing the past Book

In this case,let me say "judge a book by its memorable title."
I'd like this book to be categorized as a good literary fiction with human drama,not just a detective.
This well-written,and austerely beautiful novel has no gadget,isn't action-packed or sexy,but here one young female detective, who lost her mentor recently,walks the scenes,talks to people and gets
to the heart of things.I guess this simplicity will let you feel empathy for the charcters. I sometimes wonder how deceptive the word"simple"is.
P.D.James writes a good human story.
