A film adaptation of L'Inconnu de la poste, an investigative book by journalist Florence Aubenas, will soon be released in cinemas. The book, published in February 2021 by Éditions de l'Olivier, explores the murder of Catherine Burgod, a post office worker who was killed with twenty-eight knife wounds at her workplace. Aubenas spent seven years reconstructing the events surrounding the crime, though one episode remains unknown. The film will be directed by Patricia Mazuy and produced by Films Pelléas, with filming scheduled to begin in 2027 in the Trièves region of Isère, in the Auvergne-Rhône-Alpes area. The cast has not yet been announced, but the film will be shot in the natural landscapes of the region. Patricia Mazuy, known for her work in adapting literary works for the screen, will collaborate with Juliette de Beauchamp, a teacher and dramaturge, to adapt Aubenas's text for the film. Mazuy has previously directed Saint-Cyr (2000), based on the novel La Maison d'Esther by Yves Dangerfield, and worked with writer François Bégaudeau on Sport de filles (2011). More recently, she directed La Prisonnière de Bordeaux (2024), continuing her focus on storytelling that blends drama with real-life themes. Florence Aubenas, the author of L'Inconnu de la poste, continues her work as a journalist and writer. Her latest publication, Ici et ailleurs, is a collection of articles originally published in Le Monde, a prominent French newspaper. Through her investigative journalism, Aubenas has explored a range of social and political issues, and her work has often been adapted into film and other media. The upcoming film adaptation of L'Inconnu de la poste promises to bring the real-life mystery of Catherine Burgod’s murder to the screen, with a focus on the investigative process and the challenges of uncovering the truth. The project is expected to highlight the collaboration between journalists and filmmakers in bringing complex stories to a wider audience.
