The present pointed research is aimed at the multiple facets taken by the identity shaping of Edmée, the protagonist-narrator of the novel La fille démantelée by Jacqueline Harpman. After having considered several biography details sweeping the unique career of the Belgian author whose works mostly refer to her active profession as a psychoanalyst, our approach turned to the writing project of the heroine who writes (to herself?) the identity failure of the mother-daughter relationship, which is essential and decisive for the development of any individual. In recusing and annulling her hereditary baggage, the narrator rehabilitates herself as an emotionally stable and socially responsible adult, without recuperation or regeneration (although the trauma is impossible to erase) precisely by and due to the parentage narrative signifying identity liberation and reconstruction inaugurated by the “dismantling”, illustrating writing lucidity and honesty, indispensable ingredients in (auto)fiction.
