Lady Catherine's Necklace / Joan Aiken. (Hardcover, 1st U.S. ed)

Joan Aiken, one of Jane Austen's most sparkling successors, takes up Austen's pen yet again, this time continuing where "Pride and Prejudice "left off.
In Austen's classic novel, the arrogant Lady Catherine de Bourgh tried vehemently to prevent the betrothal of her nephew Mr. Darcy, whom she had intended for her daughter Anne, to the less socially connected Elizabeth Bennet. Defeated, she retreats to her grand estate-- Rosings Park. This enchanting sequel tells the story of what happens one balmy April day when a sudden blizzard disrupts the weather, causes a carriage accident, and affects the lives of all those involved in a most amazing way.
From out of the blizzard emerge the Delaval siblings. Miss Delaval, having twisted her ankle in the carriage accident, accepts Lady Catherine's gracious hospitality while she recovers. But the Delavals' presence proves disturbing to the entire household-- first causing the removal of two artists from their cottage home on the de Bourgh property, then meddling in Miss Anne's marriage plans. Suddenly, Lady Catherine is kidnapped, revealing some members of the household to be not at all what they seemed.
