This paper aims to read Jean Rhys`s Wide Sargasso Sea from a deconstructivist viewpoint comparing it with Charlotte Bronte`s Jane Eyre, its host text. Although commonly considered as a British writer, Jean Rhys possesses a different perspective from those of the writers born and raised in Great Britain. Being Creole, she could provide us with a perspective of the third world, unlike those of British or Europeans. This difference in perspective stands out conspicuously in her fifth novel Wide Sargasso Sea. Reading Charlotte Bronte`s Jane Eyre, one of the 19th century British classics, she was disturbed with the characterization of Bertha, the Creole wife of Rochester. To Rhys, she was an "impossible character" representing only the British side of things, therefore a character to be rebuilt and humanly reformed. Rhys brought her out from behind the stage of Jane Eyre and gave her a voice to tell us her story. Rhys not only rebuilt the character of Bertha but also did other necessary changes in her novel. In a sense, she created a totally subversive discourse, giving voice to the `muted` and marginalized group in Jane Eyre. A product of deconstructive reading, it enacts the return of the repressed or recovery of female experience from the realm of `nonbeing.` Rhys renamed Bertha as Antoinette using her maiden name, implying that name is an important symbol representing one`s identity. In this sense, it is significant Rhys does not offer any name to the husband of Antoinette although she stages him as one of the narrators - one of the deconstructive strategies. Above all, the first-person narrator/heroine of the host text, Jane, never appears and there is no space whatever that suggests any sign of her presence in the guest text. As a symbiont, Wide Sargasso Sea succeeds to deconstruct the elements of Bronte`s Jane Eyre to create a territory of nightmarish atmosphere of anxiety and uncertainty, showing us the violent oppression of Antoinette/Bertha by the "Wide Sargasso Sea" from racism, imperialism and patriarchy. In short, Jean Rhys created a novel of postmodern psychology out of the Victorian romantic novel of realism.
