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.

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.

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.

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.

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.

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.

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.

Antonino has a visitor from Sorrento on the Amalfi Coast, who brings in some of the world-famous Sorrento lemons. They prepare whole-wheat spaghetti with a simple sauce featuring lemon rind and bottarga (salted fish roe).

It's time for the girls to act. They carry out their various tasks and manage to get into Negri's studio. Eva makes a beeline for the safe. Eva is disguised, and is described by her friend as the Befana. Befana is a corruption of Epifania (Epiphany) and, in Italian tradition, the Befana is an old woman who brings gifts (or coal) for children on this holiday. Befana has also come to mean "witch."
