Abstract: Georges de Lys, author of the short story Affaire d’honneur, also published a testimony in La Croix in 1930, entitled Paul Verlaine et quelques autres. These memories, which closely match the portrait of the poet published in 1896, provide some avenues for interpreting his roman à clefs. The convergence of these two texts also invites us to question the representation of the writers and the literary sociability of the fin de siècle, caught between referentiality and fiction.
