Friday, December 13, 2015. Jihadist attacks take place in three different parts of Paris. The most serious is that of the Bataclan Room. The result is more than a hundred dead and almost half a thousand wounded. Years later, for nine months, the trial is held. There are fourteen defendants: the main one is the only survivor among the Islamic State terrorists who participated in the massacre. He survived because he did not detonate his belt with explosives. Why did the mechanism fail? Why was he afraid? Because he had a fleeting moment of regret and humanity? The rest are collaborators to varying degrees. And then there are the witnesses –survivors who tell extremely harsh stories–, the relatives of the deceased, the severe prosecutors, the defense lawyers, the court... Journalism turned into literature through the insightful gaze of Carrère.
