Seventy-six years on, Philippe Jaenada reopens the investigation. A finalist for the 2026 Prix Goncourt. [Fnac](https://www.fnac.com/SearchResult/ResultList.aspx?Search=9782080490896) Philippe Jaenada won the 124th Prix Goncourt on Tuesday 3rd November for L'inconnue du quai de Javel (Flammarion), his investigation into the unsolved death of a young woman found in the Seine in 1949. The nine members of the Académie Goncourt, meeting at the Drouant restaurant in Paris, chose him by six votes to three over Sylvain Prudhomme. It is the most prestigious award in French literature, and it comes with a symbolic cheque for €10. Its real value lies in the readers it brings to the book in the weeks before Christmas. Jaenada is 62 and has spent more than a decade writing books built from real crimes. 'My career may change, but my life certainly will not,' he said after the vote, as La Libre reported. ## L'inconnue du quai de Javel and the Death of Louise Cansot In September 1949 a young woman's body was found in the Seine at the quai de Javel, in the west of Paris. The next day the police identified her as Louise Cansot, a model who posed for several Paris painters and one of the best-known faces of Montparnasse. Detectives named four suspects but could never establish how she died, and the case was closed without anyone being charged. Jaenada goes back through the archives, walks the streets Louise Cansot knew and follows her life back to her childhood in Brittany. He takes Georges Simenon's Maigret novels with him as a guide, and he ends the book with his own answer to the case. The book came out on 12th August, runs to 528 pages and had sold nearly 60,000 copies before the prize. ## Philippe Jaenada From Le Chameau sauvage to the Goncourt Jaenada was born in 1964 in Saint-Germain-en-Laye, west of Paris. His first novel, Le Chameau sauvage, won the Prix de Flore, and he went on to write comic novels for Grasset, among them Le Cosmonaute and Plage de Manaccora, 16h30. From 2013 he turned to true stories. Sulak followed the gentleman bank robber Bruno Sulak, La Petite Femelle reopened the case of Pauline Dubuisson, tried for murder in 1953, and La Serpe, about a triple murder at the château d'Escoire, won the Prix Femina in 2017. His previous book, La désinvolture est une bien belle chose, was on the Goncourt list in 2024. He moved to Flammarion this year. 'I am counsel for the defence,' he has said of his method. 'I make my plea and the reader judges.' ### Philippe Jaenada's True Crime Books - Sulak by Philippe Jaenada - [La Petite Femelle](https://www.decitre.fr/livres/la-petite-femelle-9782260021339.html) by Philippe Jaenada - La Serpe by Philippe Jaenada ## The Three Prix Goncourt 2026 Finalists Who Did Not Win Sylvain Prudhomme, who won the Prix Femina in 2019 for Par les routes, took the other three votes with De l'autre côté du lac (Minuit). Yannick Haenel's La solitude des professeurs est infinie (Gallimard) returns to a young teacher's first year at a school in Mantes-la-Jolie. Clémentine Mélois's Choses que je croyais perdues (L'Arbalète/Gallimard) follows a woman packing up her flat after a love affair ends. All four finalists were published by imprints of Madrigall, the family group chaired by Antoine Gallimard, so the group wins whichever name came out of Drouant. Last year's winner, Laurent Mauvignier's La maison vide, also from Minuit, has sold nearly 640,000 copies. ### The Other Prix Goncourt 2026 Finalists - [De l'autre côté du lac](https://www.fnac.com/SearchResult/ResultList.aspx?Search=9782707358233) by Sylvain Prudhomme - [La solitude des professeurs est infinie](https://www.fnac.com/SearchResult/ResultList.aspx?Search=9782073161925) by Yannick Haenel - [Choses que je croyais perdues](https://www.fnac.com/SearchResult/ResultList.aspx?Search=9782073162854) by Clémentine Mélois ## The Thélyson Orélien AI Row This year's prize carries a story that began in September. On 25th September the Académie removed C'était ça ou mourir, the debut novel of the Haitian-born Canadian writer Thélyson Orélien, published by Grasset, from its first selection. It cited plagiarism in Orélien's earlier writing and several analyses that found the novel was 'in all likelihood very largely the product of an artificial intelligence'. Orélien admitted the earlier plagiarism but denied using artificial intelligence to write the novel. On 21st October his Canadian publisher, Boréal, ended its work with him. It said an outside analysis of the novel's working files had found traces of artificial intelligence in their metadata, and that it would not reprint the book or publish his future work. If you write, the case sets a marker: a book that reaches the most famous prize list in France can still lose its place over how it was written. ## A Jury of Nine and the Rest of Prize Week The jury voted with nine members instead of ten. Didier Decoin, who won the Goncourt in 1977 and led the Académie from 2020 to 2024, died on 5th August, and his seat has not yet been filled. Philippe Claudel, the novelist and film director, has been president since 2024. The Prix Renaudot, announced at the same lunch in its centenary year, went to François-Henri Désérable for Le Palais (Gallimard). The week opened on Monday with the Prix Médicis, which went to [Philippe Vasset for Dans les grandes lignes](https://thequantumoflight.com/article/philippe-vasset-prix-medicis-2026), and closes with the Prix Femina on Wednesday 4th November. The Goncourt des lycéens, voted by secondary school students from the same longlist, will be announced on 26th November. L'inconnue du quai de Javel has not yet been published in English. If you read French and like a true crime told with a novelist's eye, it is the book of the season. ### Also in This Story - [Le Palais](https://www.decitre.fr/livres/le-palais-9782073159212.html) by François-Henri Désérable - La maison vide by Laurent Mauvignier - C'était ça ou mourir by Thélyson Orélien
