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.

Eva knows Dante is keeping something from her, and she is a bit worried. Malù wants to talk to Lorenzo and he is a bit worried. The girls start making detailed plans for the caper.

Paola makes a quick decision upon meeting Grazia. Karen Bates comes back with some footage for Adriano to look at.

After the baptism ceremony in the Palatine Chapel, Adriano takes us to another historically and artistically rich site in Palermo: the Convento di Baida [Baida Abbey]. In Italian, the term convento is used more commonly than monastero [monastery] and may house either male or female religious communities.

We visit some of the narrow alleys with names that have special significance. Arianna and Simone tell the stories of these names and show us some of the beautiful ceramic pots placed around the town.

As opposed to the classical palaces of the powerful, with their throne rooms and great halls, Castel del Monte has some smaller and more intimate spaces, conducive to more personal encounters. Over the centuries, the castle was exploited in different ways, well into modern times.

The questioning continues at the station house. Manara's co-workers are keeping him up to date, in person. But they get an unexpected visit.

Eva goes to see Dante but gets a nasty surprise. But things aren't as they seem, and explanations are forthcoming. Lorenzo, on the other hand, is in a particularly good mood.

Adriano's new idea is to open a factory in the south of Italy, a very poor part of Italy. Convincing his board is a huge challenge. He takes Karen and her camera around the southern part of the country to scout for locations.

Marino meets Silvana and they start chatting by the sea. They discover that their professions are related (naturopathy and body-psychotherapy) and they enjoy sharing ways of looking at emotions and symbols.

We visit the land of the trulli, curious dry stone huts. Alberto Angela gives us some background about these unique dwellings.
