La filleule de Lagardère; I / La saltimbanque

The narrative opens with a grisly discovery at a railway bridge: a mutilated body found at dawn prompts a police and judicial inquiry described in sensational press style. Reporting, forensic detail, and official procedure introduce a mystery that unfolds across urban settings and theatrical circles. The plot alternates scenes of investigation, public curiosity, and encounters with itinerant performers, gradually revealing surprising links between the crime, social spectacle, and private lives. Themes include the appetite for sensational news, the collision of public order and entertainment, and how appearances conceal motives; suspense builds through procedural uncovering rather than singular protagonist-driven action.
