To publish her pamphlets, Francesca uses a nom de plume, namely a man who puts his name on the books at her place. When she decides to get rid of him, she sends him a letter saying she doesn't need his help anymore. After sometime the man is arrested by inquisitor Pucci, who accuses him of having violated Catholic morality in his books. The man is freed after they find out he cannot read or write. Then why did Francesca send him a letter?
