Toscani and Manara are at pretty much of a standstill as far as evidence and witnesses go, but Ada says something that makes Manara want her on the team.

We don't want to give away the ending, so let's just say that Giacomo goes back to the cafe where the redhead works and... who shows up, but Mario.

Teresa goes back to the factory, and finds out she has talent. Karen Bates, the American photographer, comes to visit Adriano, and he sees right away how he can involve her in one of his projects.

Three scenes: An article in the newspaper attracts the squad's attention, Manara questions the maid, and Fabrizio, the inspector, questions Manara.

After discovering that Mario isn't really ill, Giacomo goes looking for Professor Stern once again, hoping to find some answers.

Paola is more clearheaded after a night's sleep. Adriano isn't happy, but he has other things to think about such as the new plans for the compact typewriter. He and Libero get a visit from the girl-thief again.

The murder victim, Mr. Ponti, was on his way to the police station to report a break-in when the crime occurred.

Just when Mario felt he was getting his family back, a little karma comes his way to stir things up.

Paola is having trouble with Carlo and shows up at Adriano's in search of consolation.

We're at the beginning of a new episode, and we see right away that Luca hasn't hesitated to find some consolation... But he has to rush to police headquarters where there's been a shock for Quattroni. Waiting for him are Raimondi (the new inspector), Rosmini, Rivera, and Toscani.

Giacomo finds a way to obtain the money he needs for Mario. There are strings attached, however, and he informs his sister about it. Giacomo makes a surprise visit to Mario's house, and Ginevra makes a surprise phone call to Mario. Things are closing in on him from all sides.

Everyone is talking about Adriano Olivetti, both on Italian soil and abroad. His innovative ideas are creating quite a stir and people worry that he might be a communist.

We recognize the name of the inspector from Rome. Marta recognizes the face. Later, at the farm hotel, Luca is on cloud nine getting ready for a romantic dinner with Marta, until Ada knocks at the door with some news. She milks it for all it's worth.

Maybe, just maybe, Mario is starting to feel bad about what he is doing. Giacomo confides in his sister about the money he needs, and Mario has a surprise encounter at a vending machine he is supplying.

Adriano knows what kind of portable typewriter he wants to build and he knows who can build it. He thinks he knows what people want, even better than the people themselves.
