PD James took her time to develop the characters, the atmosphere and the plot. Let's face it, usually one of those 3 elements is missing in a mystery novel, but not this one. The characters are so real that I care about some of them - and could be moved to kill one or two of them myself. No one is a cardboard cut-out and everyone has a secret to hide. What I loved about this book was that the story was not rushed. Once I was finished with the book, I felt that everyone was alive in England still going about their business...well, at least the people who survived that is.
