Avoiding the truth does not change the truth.

When Fitzwilliam Darcy meets Miss Elizabeth Bennet, his heart is almost immediately engaged. Seeing the pretty lady before him, a lady of no consequence or fortune, he believes he should not form an attachment to her, unsuitable as such a woman is to be his wife. 

What he cannot see, however, is the truth. That the simple country girl harbors a secret. Before she meets Darcy, Elizabeth has spent two years hiding from the men who killed her beloved first husband. Feeling herself destroyed by love, Elizabeth is certain she will never love again, certainly not the arrogant man who has offended her from the first moment of their acquaintance. 

In time, Elizabeth surprises herself by finding in Darcy a friend. Even greater is her surprise to find herself gradually coming to love him and  even accepting an offer of marriage from him. As the newly married couple is beginning to settle into their happily ever after, a condemned man on his way to the gallows divulges a shattering truth - a secret that contradicts everything Elizabeth thought she knew about the tragic circumstances of her first marriage. 

Against the advice of everyone who loves her - including Darcy - Elizabeth begins to seek the truth, knowing she must have it even if it may destroy her newfound happiness with Darcy.
