Penicillium Brevicaule (S04E03)

Morgane's children urge her to reach out to the other possible fathers of her child, but she soon finds herself immersed in a fresh case. Antoine Broussin, an 85-year-old author known for his crime novels, is discovered dead in a hidden room within his house. The situation takes a complicated turn when Marie Besnard, a familiar face from Morgane's past in prison, emerges as the main suspect in the investigation.
