In this last segment, Daniela focuses on when the past participle of a verb in the present perfect has to agree (in number and gender) with the direct object pronoun when using compound pronouns. It's a bit tricky.

Arianna and Simone show us the historic center of this city on Sicily's west coast. Points of interest include its Casbah, where ceramic tile artworks tell of the city's Arab history, an unusual central-plan church; and the Satyr Museum.

Manara sneaks up on the winery owner's daughter and the stockroom guy. Toscani and Sardi ask Manara to run an errand, claiming they have 41° C fevers [105.8° F] as a ruse to get him to come over.

Peppino brings Sally, the Latin American woman from the gas station, to the hideout, thinking he is doing Martino a big favor.

After his encounter with Mauro, Adriano faints on the sidewalk. Grazia reads about his fainting in the newspaper and visits Adriano in the hospital.

Adriano has invited us to the baptism of his son Philip. It allows us to get a glimpse of one of the most beautiful places to visit in Palermo, the Palatine Chapel. The priest tells the congregation about the consecration of this famous basilica in 1040.

Wonderful aerial photography shows Castel del Monte and its crown-like octagonal shape. Frederick II was particularly fond of the castle because it was an ideal location to hunt small game with his falcons.

Luca goes to see Sardi and Toscani. He opens the door and sees a familiar face he hasn't seen in a while. They go out for some seafood together.

Eva practices opening the safe, and Dante goes to the market, none too happy about his friction with Eva. He has an unusual encounter there.

The disappearance of Martino hasn't gone unnoticed after all. A TV crew has shown up in town. Naturally, Peppino rushes off in his Ape (three-wheeler) to give Martino the good news.

Adriano's illness and hospital stay bring about a pivotal moment for relations between Grazia and her father, and not only them.

Edo is an illusionist, and with Eleonora's assistance, he shows us some tricks with newspaper cuttings and a deck of cards, all with Mount Vesuvius as a backdrop.

Arianna and Simone take us through the narrow lanes of Mazara to the little theater, built from leftover materials from ships, and on to the Casbah, full of ceramic artwork.

Alberto Angela takes us inside Castel del Monte and helps us imagine what it might have looked like when it was "alive." He uses the term piano nobile, which indicates the floor of a mansion where the noblemen or landowners lived, as opposed to the floors where the servants' quarters and kitchens would have been.

Marta and Ginevra talk about the toxicological report, but also about personal things. Luca and Lara say goodbye to each other, and Luca connects with Stefani's daughter by chance, giving him another opportunity to participate in the investigation.
