A close reading of Jean Rhys's final movement — confinement, fire, and the making of Bertha Mason.
The section opens with three italicized paragraphs from the point-of-view of Grace Poole, the character from Jane Eyre hired to look after the madwoman in the attic. Speaking to another servant named Leah, Grace explains that she was hired by a woman she calls "Mrs. Eff" (Jane Eyre's Mrs. Fairfax) and paid a significant amount of money to look after a "girl who lives in her own darkness."
Mrs. Eff instructs Grace that "there must be no gossip" about her charge, a Creole lady brought back to England by the master of the house.
Grace insists she stays because the house provides "a shelter from the world outside which... can be a black and cruel world to a woman." She speculates this is why all female servants remain — but notes the woman she looks after is not content with her restricted existence.
Antoinette takes up the narrative for the remainder of the novella, awakening as Grace lights a fire and watching the flames with great interest.
She wonders why she has been brought to the attic and forced to stay — "nights and days and days and nights, hundreds of them."
Each night she pretends to sleep while Grace drinks and counts money; when Grace falls asleep, Antoinette steals the key and wanders the darkened house.

Antoinette had written Richard a letter begging him to rescue her.
One morning Antoinette awakens with no memory of the previous day; Grace tells her that her stepbrother Richard Mason came to see her.
Richard said he could not "interfere legally" between her and her husband — he will never be coming back.
Antoinette evidently attacked him with a knife after his refusal to help.
Antoinette searches for the red dress she brought from Jamaica — the dress she was wearing the last time she saw Sandi, who kissed her goodbye. The sight of the dress on the floor makes her think of fire spreading across the room, which reminds her of something she must do. She says she will do it "quite soon now."
That night she dreams for the third time of stealing Grace's keys and venturing into the main house with a candle. She enters "a large room with red carpet and red curtains," lights more candles, then becomes anxious — the room suddenly turns into Aunt Cora's room.
She knocks the candles down, fire spreads, and she goes to the battlements where scenes of her past flash before her: Jamaica, Coulibri, Coco, Tia, Christophine, and Rochester.

She wakes from the dream and calls out. Grace comes over but Antoinette pretends to be asleep. As soon as she hears Grace snoring again, Antoinette gets up, takes the key, lights a candle, and steps out into the passage. She is going to reenact the dream and burn down the house, thus bringing Wide Sargasso Sea to the same conclusion as Jane Eyre.
Grace Poole's account is the only part of the narrative from the point-of-view of a relatively unbiased third party — she has never met Rochester and knows little about what happened in the Caribbean.
Her monologue reiterates the work's major themes, most notably that money is the root of evil: "I don't serve the devil for no money," she says, yet Mrs. Eff insists Rochester is "gentle, generous, [and] brave."

Grace explains that Rochester's father and brother have died, leaving him the entire family fortune — yet "he was a wealthy man before that."
His marriage to Antoinette, entered for purely fiscal reasons, has turned out to be unnecessary. Only by depriving Antoinette of her financial independence was Rochester able to assert his own; now that he no longer needs her money, it is far too late — Antoinette has paid with both her dowry and her sanity.
The final section overlaps for the first and only time with the storyline of Jane Eyre; by this point, Antoinette has effectively become Bertha, the madwoman originally created by Charlotte Brontë.
Although Rhys's portrait remains sympathetic, she reverts largely to Brontë's characterization: Antoinette no longer knows who or where she is, Richard Mason fails to recognize her, and she has become violent and unruly.
The conclusion — burning down the house — comes as no surprise.
In perhaps her most significant addition to Brontë's work, Rhys raises the possibility of an incestuous relationship between Antoinette and her half-brother Sandi in the final pages.
The depiction of Antoinette retains autobiographical elements from the life of Jean Rhys, who identified strongly with the madwoman she created. At the time of publication in the 1960s, Rhys was living as a recluse in a remote corner of England, drinking heavily, and was ordered by a court to seek mental health care.
Critics Sandra M. Gilbert and Susan Gubar have suggested the madwoman in the attic figures as an emblem of the woman writer — perhaps literally true of Rhys, who, like Antoinette, sought a haven where her imagination could run free.
