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.

The alternative tourism video starts by showing some of Rome's iconic sites, but will focus on less well-known quarters, such as the Salario-Trieste neighborhood in north Rome.

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.

The segment shows us some interiors in Coppedè's dream-inspired complex.

More dreamy interiors of the Coppedè complex and an introduction to the Keats–Shelley House in Piazza di Spagna.

The segment touches on Byron and Shelley, but is mostly about Keats and his time in Rome. It also includes part of a beautiful love letter to Fanny Brawne. The narrator speaks of Keats living on the second floor. The Italian way of counting stories is to call the first floor, the ground floor, and the numbering starts above.
