Downton Abbey story

As a result of a Spring Giftfic Exchange, I'm now committed to writing a fan-fiction story set in Downton Abbey -- not a fandom that I volunteered for (apparently it was so difficult to match people up that despite asking us to list at least five fandoms that we might be able to write stories for and five that we would like to receive, we almost all ended up being asked to do something that we hadn't actually offered!)
