Thou Shalt Not Kill

Valeria decides to ask Lucia, once and for all, the truth of why she killed Valeria's father. Lucia claims that her husband wanted to leave her, but she tells Giulio that she has once again lied to her daughter in order to protect her.

It seems like an ordinary administrative case: a man is run over on the highway by a hit-and-run driver. There would be no need for Valeria, but Inspector Ferro understands right from the start that things aren't as simple as they seem.

The last altercation with her mother leaves Valeria disappointed and bitter, and she wants nothing to do with her anymore. But after making peace with Lombardi, Valeria returns home to her uncle Giulio, the man who raised her like a daughter.

Giampaolo Petrone, the openly gay owner of a nightclub, is found dead. The man was not in close contact with his family, who never accepted the fact that he was gay, so Inspector Ferro begins questioning his circle of friends and acquaintances.
