Varricchio is back in the DA's office and tells a different story, admitting he had lied the first time. But is there proof of his new version? At home, Lojacono is shocked by some news he hears on the TV.

Lojacono goes to Letizia's trattoria and tells her about the bad news about the witness. She tries to reassure him but also has a new customer to attend to. Francesco can't let Giorgia go and sleeps in the car in front of her house.

At the hotel where Aragona stays, he tries to find out who the new housekeeping person is. Down at the police station, there is news concerning the prostitute Varricchio says he spent time with the night of the murder.

Laura and Lojacono go to Laura's house and she begins cooking dinner. At his hotel, Aragona has a chance to see Irene, the new housemaid, in the dining room and can't take his eyes off her. Francesco brings Giorgia breakfast in bed. It's una graffa (a kind of doughnut).

Lojacono and Di Nardo go to see Biagio's ex-girlfriend to ask her one more question. She happens to remember something that gives them a new lead. They then go and talk to Renato, Biagio's friend and colleague.

Lojacono is confident he knows how the murder happened and is able to trick Renato into saying something he couldn't have heard on the news.

The case has been solved, one gets the feeling that if the murderer had been Varricchio, a common ex-convict, instead of a promising biologist, son of a prominent professor, the outcome would have been more palatable to the city and to the press.

In a church basement, a priest leads some young people in singing to celebrate the eighty-first birthday of Mariolina. Caterina goes to find Angela, who is late with the cake.

Lojacono is on a video call with Marina, his daughter, and her friend Chanel, when he gets a phone call from headquarters and goes to a new crime scene, to see what's what.

Lojacono and DA Piras arrive at the scene of the crime and meet Don Michele. The next morning Lojacono goes with Di Nardo to talk to the kids who had been in the parish hall with the victim.

The young volunteers talk about how they met and what they were doing the night of the murder. Aragona and Romano come back to headquarters with a photo they found at the victim's home.

Lojacono surprises Laura at dinnertime. Di Nardo has dinner with Rosaria, who has an invitation for her. At the dinner table, Giorgia has something to discuss with Francesco.

A parishioner shows up at police headquarters with photos she thinks are compromising. Lojacono and Alex then go to question the volunteers as to whether the insinuations could carry any weight.

Lojacono and Di Nardo go to speak with Don Michele again, when Mass is over. The priest confirms that he and Angela cared for each other very much but that they didn't have a relationship. He is being rather defensive, but Lojacono gets him to agree to cooperate.

Rome's Coppedè Quarter is the focus of the segment. Its eclectic style is difficult to characterize, but the narrator talks of the liberty style, which stems from the Liberty department store in London. In English, we know this style by the French term, Art Nouveau.
