AZF, l'enquête assassinée examines the catastrophic explosion that occurred at the AZF chemical plant in Toulouse in September 2001. Author Franck Hériot, joined by journalist Jean‑Christian Tirat, pieces together the official inquiry, court proceedings, and the myriad theories that have surrounded the tragedy. The book presents a detailed chronology of events, from the initial blast and emergency response to the lengthy judicial process that sought to determine responsibility. Drawing on interviews, documents, and expert analysis, it explores the technical failures, possible negligence, and the broader implications for industrial safety in France. Beyond a straightforward recounting, the work reflects on how the incident shaped public policy, influenced community resilience, and left a lasting mark on the city’s collective memory. Readers interested in contemporary French history, industrial disasters, or true‑crime narratives will find a thorough and thoughtful account that balances factual rigor with narrative clarity.
