what thematic concerns are in part three of wide Sargasso sea

The first three pages of part three in the novella are narrated by Grace Poole; this narrative gives us another point of view and looks at the themes outlined below;

"Grace Poole's account is important because it is the only part of the narrative from the point-of-view of a relatively unbiased third party. Grace has never met Rochester and knows little or nothing about what happened between him and Antoinette in the Caribbean. It is not clear whether her brief moments as narrator are conversational fragments overheard and filtered through the consciousness of Antoinette; this is certainly possible, as Grace at times seems to be speaking to another servant named Leah. Grace's monologue reiterates several of the work's major themes, most notably the idea that money is the root of evil. "I don't serve the devil for no money," Grace says, but Mrs. Eff insists that Rochester is "gentle, generous, [and] brave," although his stay in the West Indies has altered him almost beyond recognition.

Grace explains that Rochester's father and brother have died and as a result he has inherited all of the family fortune; however, as she points out "he was a wealthy man before that." Ironically his marriage to Antoinette - a union he 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 independence from his father and older brother, and now that he no longer needs her money it is far too late. Antoinette has paid for his transgressions, both with her dowry and with her sanity."
