Agatha Christie is Agatha Christie and she is a delight to read, not only for her puzzles, but more important is her writing style and ruminations about life, psychology and how to understand people. Hence examples such as this: “You do not comprehend, Captain Marshall. There is no such thing as a plain fact of murder. Murder springs, nine times out of ten, out of the character and circumstances of the murdered person. Because the victim was the kind of person he or she was, therefore was he or she murdered! Until we can understand fully and completely exactly what kind of a person Arlena Marshall was, we shall not be able to see exactly the kind of person who murdered her. From that springs the necessity of our questions.”
And to have such read by David Suchet is icing on the cake.
