The BBC and HBO series Gentleman Jack brought Anne Lister to international attention, awakening tremendous interest in her diaries, which run to nearly five million words and are partly written in her secret code. They record in intimate detail the ways Anne challenged so many of societys expectations of women at the time.

In As Good as a Marriage, the sequel to Female Fortune, Jill Liddingtons edited transcriptions of the diaries show us Anne from 183638, and guide the reader through life at Shibden Hall after Annes unconventional marriage to wealthy local heiress Ann Walker. The book explores the daily lives of these two women, from convivial evenings together to Anne's ruthless pursuit of her own business and landowning ambitions.

Yet the diaries coded passages also record tensions and quarrels, with Ann Walker often in tears. Was their relationship really as fragile as Annes coded writing suggests?
