The year is 1803 – and Darcy and Elizabeth have been married for six years, with two handsome healthy sons in the  nursery; Elizabeth’s beloved sister Jane and her husband Bingley live within seventeen miles; the ordered, secure life of Pemberley seems unassailable and Elizabeth’s happiness in her marriage is complete.  But the peace is threatened and old sins and misunderstandings are rekindled on the eve of the annual autumn ball.  The Darcys and their guests are preparing to retire for the night when a chaise appears, rocking down the path from Pemberley’s wild woodland, and as it pulls up, Lydia Wickham, an uninvited guest, tumbles out, screaming that her husband has been murdered. P.D. James fuses the world of Pride and Prejudice with detective fiction – and very successfully.
