Philippe Jaenada Wins Prix Goncourt for 1949 Murder Investigation

Philippe Jaenada won the Prix Goncourt on Tuesday for his novel L’Inconnue du quai de Javel, which investigates the 1949 murder of Louise Cansot. The prize, considered the most prestigious literary award in France, recognized the book for its detailed reconstruction of a cold case that police had failed to solve for 77 years.

Cansot was a 29-year-old woman from Brittany who worked as a life model in Paris. Known as the woman with a hundred portraits, she was highly sought after by artists in the Montparnasse district. She was found dead on September 7, 1949, but investigators never identified the person who killed her.

The original police investigation produced a 300-page report that described Cansot as a woman of ill repute. Contemporary newspaper reports speculated that she was a sex worker or a drug addict. Jaenada’s 530-page book challenges that narrative by portraying the victim with empathy and suggesting a specific suspect for the murder.

Le Monde praised the author’s effort to understand his heroine, noting the book’s humor and grumpy tenderness. The publication highlighted Jaenada’s method, which involved reading and re-reading 74 of the 75 novels in George Simenon’s Inspector Maigret series. The Maigret character served as a structural inspiration for the investigation into 1940s Paris.

This victory marks the thirteenth novel of Jaenada’s career and his first major award after four previous shortlists for the Goncourt. The writer, born in the Île-de-France region, has focused on old news stories since publishing Sulak in 2013. That earlier book detailed the activities of a charismatic robber who targeted jewelry stores in the 1980s.

The selection process for this year’s prize was complicated by an allegation involving another longlisted author. Thélyson Orélien, a Canadian-Haitian writer, faced claims that his novel C’était ça ou mourir was almost entirely written by artificial intelligence. The Académie Goncourt withdrew the book from consideration, and his publisher Boréal severed ties following an internal review. Orélien has denied using AI to write the text.

Jaenada’s book offers a corrected view of Cansot’s life and death. It details how she left Brittany at age 16 to work as a maid before sitting for painter Jean-Louis Boussingault, who introduced her to other Parisian artists. The novel stands as a final resolution to a case that remained open for three-quarters of a century.
