Abstract: Detective novels give the work of Pierre Senges its own playfulness and even a matrix. Following the paths suggested by Jacques Dubois, the article shows how indiciality, which offers the world for description and commentary, the figure of the investigator-reader, who makes the invenstigation an end in itself, as well as the modality of struggle, opposing the guilty party and the detective or even author and philologist, reveal some of the strands of meaning of the work, especially in its relationship to erudition.
