[1] The drama was written and directed by Sally Wainwright and focused on the relationship of the three Brontë sisters; Charlotte, Emily and Anne, and their brother, Branwell.

[2] In the United States, it aired on 26 March 2017 on PBS as part of Masterpiece Theater, under the title To Walk Invisible: The Brontë Sisters.

[3] The title of the drama comes from a letter that Charlotte Brontë had written to her publisher about once meeting a clergyman who did not realise that she was Currer Bell.

Later Anne also confides to Emily that she is terrified by Branwell's drunken behaviour, as their father is blind and sickly and their house belongs to the parish, meaning that when he dies the sisters will be wholly dependent on their brother who is a liar, a heavy drinker, and a spendthrift.

Emily reacts violently to the breach of privacy, while Anne is intrigued by the idea of publication and shows Charlotte some of her poems and a novel she is working on.

Charlotte takes their father for cataract surgery and during his recovery period she begins work on a second novel, Jane Eyre.

[11] Lucy Mangan, writing in The Guardian, described the drama as "bleak, beautiful and brilliant; like everything that Wainwright and her repertory company does".

[12] The Telegraph's Jasper Rees gave the drama five stars out of five describing the episode as "the Brontë sisters brought to fizzing, furious life," and similarly praised Adam Nagaitis' acting, noting that it was excellent.

[13] The programme also attracted numerous comments on social media, with many viewers expressing their displeasure about a fine performance ruined by what they felt to be the poor quality of the film's sound recording.

[15] Hewitt was critical of what she saw as Branwell's character being overplayed, Charlotte's "constant mean pinched look" and the representation of Patrick Brontë as "mild and ineffectual" when she claims he was a "fiery Irishman, Cambridge graduate, [and a] forward-looking social reformer.
