A/N: Thank you all for your responses. You guys are the best. As for why these letters are rated M, that shall be revealed later. Many of you must be waiting for some E/D fluff. Take a closer look and you shall find many fluffy bits hidden here and there. Now this letter might come as too forward but I like it. I believe that Darcy truly accepted the Bennets as his own family despite their li'l flaws and this is just a glimpse of it.
Reviews are awesome like chocolates with a surprise filing inside. Enjoy!

Pemberley,

9th December 1813

Dear Father,
I have received your letter this afternoon and it has indeed found us in excellent health. We are relieved to hear that Mrs. Bennet has recovered from her cold. However, I am a bit disappointed by the particular portion of your letter where you, yet again, apologized for 's 'accident' as I like to call it .Believe it or not, dear father, we are a family now and along with the Bennets, Lydia too is a part of my family .My Georgiana and she is of same age and if Georgiana did something foolish like Lydia, she would have been forgiven for my love for her far exceeds the anger for her childhood mistakes. Lydia is now my sister too and any past misdeeds are forgiven. Though, I cannot say the same for Mr. Wickham.

Yes, they have asked to come and stay here at Pemberley but were dismissed by Mrs. Darcy. Lydia is certainly welcome but only without her husband.
Elizabeth has planned a Christmas ball at Pemberley this year and we all want you to come to Pemberley with your family as soon as it is possible for you. Elizabeth dearly needs your soothing company to keep a check on her hidden nervousness about hosting the ball and she misses you very much. I too, look forward to some quality time spent in the vast library of Pemberley with you and some port. A fresh collection of Latin and German dictionary has just arrived and we all are waiting for you to unseal them .Georgiana is eager to meet Mary and Catherine and she hopes they will arrive here sufficiently in advance to plan their outfits for the ball together .I send my best wishes to Mrs. Bennet and my wife is already writing her a letter that would complete the confirmation of our eagerness in your presence.
May you have a safe journey.
Yours & c.

Fitzwilliam Darcy
