Despite mutual acquaintances begin to chatter about their relationship, Anne confides her hopes for a future with Ann Walker to her aunt. Meanwhile, the Rawson brothers step up their attempts to out-maneuver her in the coal business, and Marian grows annoyed that her sister is treating Shibden like a hotel.

During a visit to York, Anne is delighted when Doctor Belcombe confirms that she is the perfect tonic for Ann Walker's nervous disorder. When the news of a bereavement arrives at Cliff Hill, Ann's desperate reaction makes Anne suspect that there's more to it and that Ann has secrets of her own. As her rivalry with Christopher Rawson heats up, Anne plans to re-open her old coal mines and sink her own shaft.

With Ann Walker's mental health in an alarming downward spiral - and her overprotective relatives watching over her – Anne Lister is forced to contemplate travelling alone, despite her family's warnings that to do so would raise eyebrows. Meanwhile, Anne reopens her coal-mine negotiations with the Rawson brothers, and Thomas Sowden's secret casts a cloud over his budding relationship with Suzannah Washington.

Before setting off for Europe to escape the heartache of her doomed relationship with Ann Walker, Anne invites Christopher Rawson to Shibden to rebuke him for publicly insulting Marian. Undeterred by his warnings that her accusations will have dangerous repercussions, Anne comes up with a bold, reckless strategy to finally sink her own pit and expose the Rawsons' industrial-scale theft of her coal.
