Fingersmith recap

Susan Trinder, raised in a London thieves' household, agrees to become maid to the wealthy Maud Lilly as part of Gentleman's plan to marry Maud, seize her fortune, and confine her. Sue and Maud fall in love, but after the marriage Sue is committed in Maud's place. Maud's narration reveals that she knew the scheme and had been promised escape from her uncle's oppressive home, though Gentleman then delivers her to Mrs Sucksby. Sue escapes the asylum and returns to Lant Street. There she learns that she and Maud were exchanged as babies: Sue is the Lilly heir, while Maud is Mrs Sucksby's daughter. Gentleman dies in the ensuing struggle, and Mrs Sucksby is executed after taking responsibility. Sue eventually finds Maud back at Briar, supporting herself by writing erotic fiction. Recognizing how both were used, the two women reconcile and remain together.

Susan Trinder has grown up in a thieves' household in Lant Street under the care of Mrs Sucksby and Mr Ibbs. A confidence man called Gentleman proposes a profitable deception. Maud Lilly, an orphaned heiress, lives at the isolated country house Briar with her scholarly uncle. Gentleman has entered the household under another name and plans to make Maud fall in love with him. Once married, he can have her declared insane and take control of her fortune. Sue is to pose as an experienced lady's maid, encourage the courtship, and help manage Maud; in return, she will receive a large payment. At Briar, Sue finds Maud timid and closely governed by her uncle's routines. As Sue learns the duties she only pretended to know, Maud begins to rely on her. Gentleman presses his courtship while Sue tries to treat the vulnerable young woman as merely the object of a fraud.

Sue becomes Maud's confidante and helps Gentleman create opportunities for a secret courtship. The closeness between the two women develops into mutual desire, making Sue increasingly ashamed of the plan, but loyalty to Mrs Sucksby and fear of Gentleman's reaction keep her from confessing. Maud agrees to flee Briar and marry Gentleman. After the private wedding, the three travel toward London and stop at a mental asylum, supposedly to arrange Maud's confinement. There the deception reverses: Maud and Gentleman identify Sue as the delusional wife, using Sue's own history and behavior to support their story. The doctors accept their account and imprison Sue under Maud's name. Maud leaves with Gentleman, while Sue realizes that the woman she meant to betray has anticipated and redirected the entire scheme against her.

The story returns to Maud's childhood. She spends her first years in a harsh institution before her uncle takes her to Briar. He trains her to read aloud and assist with his private collection of explicit books, presenting her to male collectors while keeping her ignorant of ordinary life. Maud learns to hide disgust and anger behind obedience. Mrs Stiles enforces the household's rules, and the library becomes both Maud's work and the instrument of her confinement. By the time Gentleman arrives, Maud understands that her inheritance will not necessarily free her from her uncle's control. His offer of escape therefore reaches someone who is sheltered but not innocent, practiced in performance, and desperate to choose what happens to her own life.

From Maud's perspective, Gentleman offers a scheme in which Sue will be confined and Maud will escape Briar with a share of her fortune. Maud recognizes Sue as an accomplice but still becomes emotionally and sexually attached to her. She considers abandoning the plot, yet years of coercion and Gentleman's pressure lead her through the marriage and the substitution at the asylum. Her apparent calm during Sue's commitment conceals the cost of the betrayal. Gentleman then takes Maud to Lant Street rather than granting the independence he promised. Mrs Sucksby receives her with unsettling familiarity and helps keep her confined. Maud discovers that Gentleman and Mrs Sucksby have additional plans for her money and that the Lant Street household is connected to her past in ways she was never told. Both women are now trapped under each other's identities: Sue in the asylum as Maud, and Maud among the people Sue believed were her family.

Sue refuses the identity forced on her at the asylum, but her insistence that she is Susan Trinder is treated as evidence of madness. She learns enough about the institution's routines to seize an opportunity to escape. With help connected to Charles, the servant boy from Briar, she makes her way back toward London, determined to confront Maud and Gentleman. At Lant Street, Maud remains under Mrs Sucksby's control while the adults wait for the financial arrangement attached to her supposed identity to mature. She begins to understand that the fraud at Briar was only one layer of a longer plan. Sue's return brings the two halves of the story together, but each still believes the other knowingly chose the betrayal that ruined her life.

Sue reaches Lant Street and confronts Maud, Gentleman, and Mrs Sucksby. The struggle exposes the older secret behind the inheritance: Sue is the daughter of Marianne Lilly and the rightful heir, while Maud is Mrs Sucksby's biological daughter. The babies were exchanged, placing Maud in the Lilly family and Sue in Lant Street, and the later fraud was designed around that hidden substitution. Gentleman is fatally stabbed during the confrontation. Mrs Sucksby claims responsibility and is executed, protecting Maud and leaving Sue access to Marianne's written explanation. Sue initially separates from Maud, convinced that too much betrayal lies between them. Eventually she returns to Briar and finds Maud there, earning money by writing erotic fiction. Their meeting clarifies that each loved the other and that both were manipulated by Gentleman and Mrs Sucksby, even while making damaging choices of their own. Sue and Maud reconcile and remain together at Briar, no longer living inside the roles others designed for them.

Sue escapes the asylum and returns to Lant Street, where she discovers Maud living under Mrs Sucksby's control. The confrontation exposes a scheme older than Gentleman's fraud: as infants, Sue and Maud were exchanged. Sue is Marianne Lilly's daughter and the true Lilly heir, while Maud is Mrs Sucksby's biological daughter. Gentleman dies during the struggle. Mrs Sucksby accepts responsibility for the killing and is hanged, protecting Maud while leaving Sue Marianne's written explanation. Sue initially believes Maud knowingly stole her entire life and separates from her. When Sue later returns to Briar, she finds that Maud has survived by writing erotic material for sale. Their conversation establishes that both were manipulated and betrayed, even though each also betrayed the other under pressure. They acknowledge their love and reunite at Briar. The inheritance plot is resolved, Gentleman and Mrs Sucksby are dead, and Sue and Maud end the novel together with a chance to build a life outside the identities others imposed on them.
