Abstract: Kevin Saliou looks at an intertextual exchange: in La Plus Secrète Mémoire des hommes, Mbougar Sarr, disciple of Roberto Bolaño, sketches the portrait of a doomed poet with a resemblance to both Rimbaud and Ducasse, while the name of Lautréamont appears frequently in Les Détectives sauvages. The three authors question the practice of plagiarism.
