Patrick Modiano: The cartography of an author, the writing of a city is an investigation on the role the memory and the city s physical space play in the writing of Patrick Modiano, especially in the book So You Don t Get Lost in the Neighborhood (published in 2015 in Brazil under the name Para você não se perder no bairro and originally in France in 2014 as Pour que tu ne te perdes pas dans le quartier). The 2014 Nobel Prize winner in Literature s literary project is marked by the existence of autobiographical elements and is considered by many critics as autofiction. The present study tries to understand which thematic, linguistic and narrative traits are characteristic of his writing and also uses interviews given by the author to achieve so. It then analyses the different conceptions of memory that can be associated to the author and how these may appear on his texts. The research shows how forgetfulness occupies a prominent place in So You Don t Get Lost in the Neighborhood and the link between the protagonist s process of remembering and Paris, therefore observing how the space may be seen as a repository for memory. Thus, the present work investigates how Modiano draws a map of experience in his books, creating an emotional cartography from remnants of the past.
