P.D. James, the British author whose cerebral murder mysteries brought a new level of sophistication to the genre and who created such enduring characters as the erudite but melancholy Scotland Yard sleuth Adam Dalgliesh and the resourceful private investigator Cordelia Gray, died Nov. 27 at her home in Oxford, England. She was 94. Her publisher, Faber and Faber, announced her death. The cause was not disclosed. http://www.washingtonpost.com/enter...4a30b6-7645-11e4-a755-e32227229e7b_story.html
