Louis Arnaud, a former French hostage, has penned "La Révolution intérieure," detailing his nearly two-year captivity in Tehran's Evin prison and its profound impact on his life. Initially imprisoned due to his foreign status, Arnaud emerged with a deep connection to the Iranian people's struggle against the Islamic Republic, viewing their fight for freedom as his own. He describes his experience in Evin as transformative, finding a new purpose in advocating for those still seeking liberation. Arnaud, who first visited Iran in 2018 and was captivated by its culture and hospitality, feels a moral obligation to use his newfound freedom to become a spokesperson for the Iranian people, expressing a debt of gratitude to those who saved his life.
