The Mystery of the Yellow Room

Jo, a journalist, learns that her childhood friend Mathilde, now in a coma, was the target of an attempted murder. The attack took place in a locked room, and no trace of the assailant was found. Accompanied by Sainclair, a podcaster on the hunt for a scoop, Jo returns to L'Artuby to investigate. Larsan, a Marseille police officer, arrives to close the case and disapproves of their parallel investigation.
