France's best-selling novel of the year, "C'était ça ou mourir," was classified as AI-generated by detector Pangram and subsequently withdrew from the prestigious Goncourt prize after winning multiple other awards.

Lucide, a French-language detection competitor, ran the book's 59,488 words through Lucide 3.0 and agreed: all 34 chapters plus the epilogue were flagged as AI-generated — 34 at 100%, the last at 96.7%. Four independent runs on large 13,500–17,900-word blocks yielded identical results. As a control, ten pre-2022 texts including three by the author were all classified as human-written.

One of the highest-profile alleged AI-authorship controversies in literature, reigniting debate over AI detector reliability and false positives.
