Liddington's book Female Fortune: Land, Gender and Authority was chosen by feminist and TV writer Sally Wainwright as the book she would want with her to read if she was ever trapped on a desert island. Wainwright subsequently developed a historical TV drama series, Gentleman Jack, as a BBC-HBO production which aired in spring 2019 and depicts the life of Victorian landowner Anne Lister, as “the first modern lesbian”. The end credits acknowledge that the drama was “inspired by the books Female Fortune and Nature’s Domain by Jill Liddington”, whose own website declares: “Ever since her death in 1840, Anne Lister of Shibden Hall has exerted a magnetic attraction... The most powerful magnet remains her daily diaries. These run to no fewer than four million words, much of it written in her own secret code. Anne Lister’s code was not cracked till fifty years after her death. I remained hooked by Anne’s extraordinary life: dazzling worldly achievements plus unbuttoned lesbian affairs.”
