Ahmed Ben Bella
Collobert was active in the FLN and involved in missions in Algeria. After a self-imposed exile in Italy from May to August 1962, she returned to collaborate with the Algerian magazine "Révolution Africaine" until it stopped being published during the Presidency of Ahmed Ben Bella. After rejection by Les Éditions de Minuit, her cause was supported by Raymond Queneau, which led to Gallimard publishing "Meurtre" in 1964.
