The novel Panthères by Valentine Vendôme is set to be adapted into a television series by Gaumont, a major French audiovisual production company. Gaumont has acquired the rights to adapt Panthères, which is the first detective novel by Valentine Vendôme, published in April of last year by Michel Lafon editions. Known for producing popular series such as Lupin and Pax Massilia, Gaumont has tasked Sophie Kovess-Brun with developing the adaptation. Kovess-Brun is a notable television producer, having co-created 37 Secondes, which won the Best Series award at the Séries Mania festival in 2025. She is also a co-creator of La Vie dont nous rêvions, a series set to air on Arte. While the format of the adaptation has not been officially announced, Kovess-Brun's professional profile mentions a project titled Panthère? for 2026, described as a six-episode series with each episode lasting 52 minutes, focusing on an investigation that moves between crime scenes and courtrooms. Panthères was published on April 2, 2026, by Michel Lafon, and initially printed in 8,000 copies. According to Elsa Lafon, the book's launch included this print run. As of now, Edistat data shows that the novel has sold 3,454 copies since its publication. The story follows Maxime Saint-Clair, a deputy prosecutor, who investigates the death of a child. As the plot unfolds, the case gradually reveals connections to her own personal history. Valentine Vendôme is the pen name of a real-life prosecutor. After completing a hypokhâgne (a preparatory year for higher education) and studying law, she became a lawyer at the bar of Lorient. However, she later shifted her career toward the judiciary. An internship at the court of Melun convinced her to pursue a career in the legal system, leading her to join the National School of Prosecutors. She began her career as a prosecutor at the Meaux prosecutor's office before moving to Paris, where she now works as a deputy prosecutor. This professional background directly influences Panthères, her first novel, published by Michel Lafon.
