Imma and Calogiuri enter the cave where the footing is uneven and the two are thrown together. The police have found the boy and De Nardis is called into headquarters for more questioning.

De Nardis ends up confessing to how things went. He is held responsible for both Stella's and Eustacchio's deaths. Imma is still perplexed, however.

Imma clears up some more questions with Eufemia Abate about the person Stella was smiling at in the photograph.She has that person summoned for some questioning.

With Francesco Calenzano, whose nickname is Franco, Imma reminisces, in a friendly way, about the summers when they were younger and about the music they would listen to, notably, E ti vengo a cercare (I'll come looking for you).

Calenzano felt the need to tell Imma and Calogiuri some details about his childhood in Switzerland so that they would be able to understand what had happened between him and Stella.

In front of Imma, Calogiuri, and Diana, Calenzano describes every detail of when he went to Stella's apartment to see her. He's distraught, as he relives the experience.

Calenzano finishes telling his story and Calogiuri takes him away. Stacchio's teacher stops by Imma's office with a pupil, Nicolas, who has a story of his own to tell.

Pietro goes to his saxophone teacher's house to help her with a technical problem. At home, Imma gets an important phone call that has nothing to do with the case she just solved.

Imma appears to be on the psychiatrist's couch, describing a dream, but the situation becomes more and more bizarre and we don't really know what's real and what isn't.

Imma had been dreaming and wakes up to a call from Don Mariano who wants to see her, urgently. But she has another emergency to deal with first.

Imma is still worried about her husband ending up in the hospital when, back at work, Diana has bad news for her. Imma remembers her appointment with Don Mariano, but that's not the worst of it.

Imma goes to the Foundation where Don Mariano had his office. She and the team look for the tablet and talk to the young man who helped out there. They also talk to the housekeeper Ilona, who says there were plenty of people out to get Don Mariano.

Imma goes to the hospital and can't help looking at Pietro's phone while he is sleeping. Back at the office, Diana is in tears because her husband wants a separation.

Imma is talking with Mottola to find any connections with Don Mariano's death. He is accusing the deceased of not having helped him, and at a certain point, she says: Ma si rende conto? (but do you have any idea?) For more on this expression see our lesson. Back home, Imma is irritable, but she can't talk to her daughter about the real reasons she is upset.

Writer and scholar Fulvio Benelli shows us a part of Rome that tourists always flock to: Piazza Navona. But he tells us the fascinating story of how it came to be.
