Dr Patrick Grandet, 65, retired, is found charred in his home, where illegal medicines are found. The PJ finds out that even though removed from the College of Physicians for organ trafficking, he had also saved several teenagers from a burning bus fifteen years ago, which makes Adèle think the means of the murder necessarily refer to this episode. While Argos's lawyer menaces her, Adèle watches the video her captor left her thanks to Rocher's sister in-law and discovers that her parents had another daughter in 2001, a year before they died; Hyppolite will help her to find her. Lieutenant Prevost substitutes temporarily Emma.
