Author Dodie Smith may be more famous for writing "The Hundred and One Dalmatians", but I Capture The Castle is arguably her best work. Voted number 82 in the BBC Big Read's survey of the nation's favourite novels, it's the coming-of-age tale of the Mortmain sisters, who live in "genteel poverty" with their father, stepmother, and younger brother in a crumbling English castle. This 2003 adaptation of the novel stars Romola Garai and Rose Byrne, and it really brings the book to life. If you love period dramas, this one's for you.
