Many HP fans are also fans of the period drama Downton Abbey, some drawn to the show initially by the appearance of the redoubtable Maggie Smith as the Dowager Countess.
There are a number of HP fanfic writers who are also writing DA fanfic. For a really sweet one-shot about Carson and Lady Mary, check out Hogwarts Duo’s “Sixpence for Your Thoughts” over on fanfiction.net.
Sixpence for your thoughts
Summary: Carson to Lady Mary: “Suppose I give you a sixpence to spend in the village instead?” What did Mary buy with her sixpence and how does it play into their futures? A hint of Carson/Hughes at the end.
Rated: Fiction K – English – Family – C. Carson & Mary C.

Thank you for the link. This does look like a very enjoyable show, and I do look forward to seeing Maggie Smith as the Dowager Countess.
Now to give Hogwarts Duo’s story a read. 🙂
You can watch Downton Abbey on streaming video from Amazon.com, and I think it’s also available on Netflix. (If you have Amazon Prime, you can watch all the available DA episodes for free. A nice little bonus! 😉 )
