The disturbing correspondence that linked Albert Camus and René Char with Jean Sénac, then a young poet in construction, brings us through the small door into this intimate universe of the process of writing. Between them no incense, but precious advice, jokes, confidences... In their texts or letters they tell each other and try to describe what underlies their work. Ten years after their first exchanges, the divergence of points of view between Albert Camus and Jean Sénac in the face of the first fratricidal struggles of the Algerian War gives rise to bitter and disturbing letters that question us by-beyond time on the difficulty of positioning oneself in the face of the painful events of history.
