Death Comes to Pemberley, Paperback/P. D. James

In their six years of marriage, Elizabeth and Darcy have forged a peaceful, happy life for their family at Pemberley, Darcy's impressive estate. Her father is a regular visitor; her sister Jane and her husband, Bingley, live nearby; the marriage prospects for Darcy's sister, Georgiana, are favorable. And preparations for their annual autumn ball are proceeding apace. But on the eve of the ball, chaos descends. Lydia Wickham, Elizabeth's disgraced sister who, with her husband, has been barred from the estate, arrives in a hysterical state--shrieking that Wickham has been murdered. Plunged into frightening mystery and a lurid murder trial, the lives of Pemberley's owners and servants alike may never be the same.
