Philippe Jaenada has spent over a decade turning French true crime into literary form, and L'Inconnue du quai de Javel is the fullest expression of what that project looks like at full stretch. Louise Cansot left Brittany at 16 to work as a maid, found her way into the Montparnasse art scene through painter Jean-Louis Boussingault, and became, by some accounts, the most sought-after life model of her generation — "the woman with a hundred portraits." She was found dead on 7 September 1949, aged 29. The murderer was never identified. The original 300-page police report concluded she was a woman of "ill repute," and newspapers of the time speculated freely about sex work and drug addiction. Nobody was particularly troubled that the case went unsolved. Jaenada's book is 530 pages long, which is either the right length or excessive depending on your tolerance for immersive digression — Le Monde's praise for its "touch of grumpy tenderness" suggests the former. The ambition here is double: identify the killer and rehabilitate the victim. These are not separable projects. The original investigation failed partly because the investigators decided in advance who Cansot was, which meant they also decided who mattered. Jaenada's methodology is the opposite: read everything, assume nothing, and let the portrait accumulate from evidence rather than prejudice. The Prix Goncourt win — Jaenada's fifth shortlisting and first victory, with his thirteenth novel — arrives in a particularly charged year for French literary prizes. The runner-up controversy centered on Thélyson Orélien's C'était ça ou mourir, which was pulled from the Goncourt longlist after allegations it was "almost entirely" written by artificial intelligence. His Canadian publisher Boréal severed ties with him; Orélien denies the charge. The irony lands hard: the prize that went to a book about restoring authorship and personhood to a woman erased by institutional failure was contested by a book whose human authorship was itself in question. The Maigret connection is not incidental. Jaenada re-read 74 of the 75 novels in Simenon's Inspector Maigret series — the chief inspector of a criminal brigade in 1940s Paris — before writing this book. That's the era, that's the city, that's the institutional culture he's working to understand and argue with. Simenon's Maigret is famous for empathy as investigative method: understand the victim and the milieu, and the crime clarifies. Jaenada is doing the same thing, but with the added awareness that Maigret's institutional counterparts in actual 1949 Paris did not share the method. What keeps this from being archival pedantry is the voice. Jaenada's style — digressive, humorous, obsessive, personally invested — has been his signature since Sulak (2013), the story of a charismatic jewellery robber who became a minor celebrity. The books work because the narrator's proximity to the material is itself the subject: you're watching a writer become consumed by a person who was erased, and the consumption is generative rather than exploitative. That's a difficult needle to thread, and the fact that Jaenada has threaded it here, on this subject, is why Le Monde specifically praised both the book's humour and its empathy in the same breath. These are not usually the same quality. The 77-year gap between the crime and the prize is its own kind of data point. France's most prestigious literary prize going to a book about institutional failure to see a woman clearly — a book that required a novelist's obsession and 530 pages to do what a police report never managed — is not a comfortable verdict on the culture that produced the original investigation. Whether that discomfort registers beyond literary circles is a different question.
