Fresh Air's book critic Maureen Corrigan interviews British mystery novelist P. D. James. James has just published her fifteenth book, "A Certain Justice," which is already on the New York Times Best Sellers List. James talks to Corrigan about the nature of the mystery novel and the differences between British and American mystery novels.
The writer, known for her grisly descriptions of crime scenes, lives a quiet life as a grandmother in her 60s. Her novels focus on psychological themes rather than the tightly-plotted mysteries associated with the works of Agatha Christie.
