Through an approach combining poetic of the narrative and sociocritique, the study demonstrates that narrative strategies such as free indirect speech break the invisibility of the marginal to give him a human thickness. The analysis of spatial symbolism shows that the wall is used as metaphor of an identity suspended between the failure of urban integration and an inner exile. By understanding this drama in the tradition of French-speaking Algerian literature, this work highlights a radical critique of institutional violence and social contempt.frMarginalityWallFrancophone Algerian LiteratureMimoun AyerSociocriticismUrban SpaceSocial MalaiseNarratologyThesis
