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.

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.

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.

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.

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.

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.

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.

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.

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.

Teresa is distraught over Libero's marriage and is having a hard time working. Adriano tries to console her and shares his problems with her. Later on she gets a shock.

Lorenzo is clearly having a rough time and would like to talk to his mom, but he often loses his courage. This time Eva keeps pushing and the conversation goes a bit further. Eva goes to see Negri in his office and of course, she keeps her eyes and ears wide open.

We say goodbye to Agrigento's Valley of the Temples and get a close look at the awesome Riace Bronzes in Reggio Calabria. The two life-size Greek bronzes date to the 5th century BC and were discovered off Riace by a scuba diver in 1972.

Yabla students wrote in with some questions for Adriano. He answers them in this video, with the help of his mamma.

Adriano and Grazia meet happily, but only for a few minutes. At the factory, Adriano introduces the new general director to Mauro and Alessio. This is unexpected, disconcerting news for Mauro.
