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.

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

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.

Adriano's illness and hospital stay bring about a pivotal moment for relations between Grazia and her father, and not only them.

Luca goes to see Sardi and Toscani. He opens the door and sees a familiar face he hasn't seen in a while. They go out for some seafood together.

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

Manara sneaks up on the winery owner's daughter and the stockroom guy. Toscani and Sardi ask Manara to run an errand, claiming they have 41° C fevers [105.8° F] as a ruse to get him to come over.

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.

Marta has conversations with both Manara and Raimondi, neither of which is she too happy about. The term innominato or unnamed makes reference to the evil character in Alessandro Manzoni's novel, I Promessi Sposi (The Betrothed).

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 squad interrogates Pupi, the murder victim's coworker at the winery. Luca gets to listen in on the interrogation and the ensuing discussions via Toscani's cellphone.

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.

Rivera and Raimondi go looking for Mister Binacci, the victim's friend, with whom he had bought the boat. Manara is there, lurking, and Marta avoids him being seen by Raimondi. Meanwhile, Toscani and Sardi obviously have a secret and don't agree about whether to tell Luca about it.

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.

Manara can't sit still, and goes to see Ginevra after hours, casting a "casual" glance on the murder victim. Marta and Toscani show the security camera DVDs to Raimondi. Manara goes to the pier to get information from a guy he knows there.
