A harmless waste paper basket fire in the classroom gives our Professor an idea. She engages the help of one of her students.

Lara is doing some thinking, and confides in Sardi. Meanwhile, there is a definite lead in the case about the burglarized villas.

This evening Camilla's mother will take care of Livia, who is complaining about the dog again. Camilla and her husband go to the opening of an art gallery, where they have a hard time finding the appropriate words when meeting the artist.

Lara has a hard time resisting Luca's charms. Sardi and Toscani don't seem to be on the same wavelength. But somehow, they are getting closer to having some interesting information, if not concrete evidence.

Commissioner Berardi shows up at the gallery opening, and Camilla exchanges a few words with him. This doesn't go unnoticed by the gallery owner, who is very curious. Meanwhile, Camilla's husband has a bizarre conversation with the artist.

The case is discussed at the dinner table among Lara, Luca and Aunt Caterina. As usual, Caterina knows a lot about the people involved. She also gives Lara some advice.

Camilla gets her husband to help with the case by invoking her dead father and concocting a story about playing Lotto.

Luca finds out some important information from the housekeeper, and he also finds out, quite by accident, about Lara's course in Milan.

Camilla is taking risks to figure out who killed Nicola. But Commissioner Berardi shows up in time to whisk her away. He's none too happy about her interfering, but in the end, she gives him a hand by identifying some suspects.

Toscani knows he's doing a good job, but is frustrated because Manara doesn't ever acknowledge it. Meanwhile, Luca must have an idea since he goes prancing around the office. In fact, he knows exactly what he's doing.

Camilla goes to the police station to identify the two thugs who had attacked her, and who sold the drugs to Marta. She also confronts Marta who has been brought in for questioning, and who is wondering who on earth Camilla is, and what she wants from her.

In this episode, we have the straw that breaks the camel's back as far as Lara is concerned. Toscani has a good moment.

Camilla's husband and daughter watch the video recording of the missed game on TV while Camilla decides what to do the next day (with the help of her dog), and enlists her husband's help.

In the case, the sad truth comes out. Luca and Lara are both very somber for their own reasons. The only happy person seems to be Toscani who discovered traces of blood on the cane.

Camilla visits Marta to try and talk some sense into her, but then they both look out the window and see trouble coming in the form of two thugs Marta recognizes. Of course, Renzo is blithely reading the paper in the car, and has Camilla's cell phone. What to do?
