On January 9, 1993, Jean-Claude Romand killed his wife, his children, his parents and then tried in vain to kill himself. The investigation revealed that he was not a doctor as he claimed and, more difficult still to believe that it was nothing. He lied for eighteen years, and this lie not covering anything. Close to being discovered, he preferred to remove those he could not bear the look. He was sentenced to life imprisonment. I came into relationship with him, I attended his trial. I tried to tell precisely, day after day, this life of solitude, and lack of deception. To imagine that turning in his head over the empty hours, no project or a witness, he was supposed to go to work and actually spent on parking or highway in the forests of the Jura. To understand, finally, what in human experience so far has touched me so closely and touch, I think all of us.
