Eva pays a visit to Augusto, a friend and safe-cracking expert, while Lorenzo and Malù break up. Later, Eva and the ladies hold a planning session for their caper.

Adriano asks Karen Bates to travel to Italy's southern regions to scout out a location for an Olivetti factory. Mauro, after being passed over for a job, decides to go and work for Dalmasso.

The first stop is Italy's easternmost point, the Punta Palascìa and its 19th century lighthouse. Alberto Angela then shows us another site in the Apulia region, Castel del Monte, a breathtaking crown-shaped castle built by Frederick II in the early 1200s.

Ferruccio, the kitchen hand, tells Dante about a conversation he overheard and this creates a little friction between Eva and Dante. Lorenzo hasn't been showing up for meals at the restaurant and Eva learns why.

We learn why Dalmasso asked Mauro to stay on at the Olivetti firm. Adriano pays a visit to Mauro's house to find out if his suspicions are correct.

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

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.
