Elizabeth has found her footing as the chatelaine of the great house. They have two fine sons, Fitzwilliam and Charles. Elizabeth's sister Jane and her husband, Bingley, live nearby; her father visits often; there is optimistic talk about the prospects of marriage for Darcy's sister Georgiana. And preparations are under way for their much-anticipated annual autumn ball. But now, Pemberley is thrown into chaos after Elizabeth Bennett's disgraced sister Lydia arrives and announces that her husband Wickham has been murdered
