Lojacono and Aragona interview 2 of the notary's employees, while Romano and Di Nardo go back to the mysterious girl's apartment, this time with a warrant.

The architect is not happy about his visitors from the police and is on the defensive about Nunzia, the girl. As he is having dinner at his usual spot, Lojacono gets a phone call from the PM.

Aragona meets up with Marina outside of the workplace and she feels freer to give up some information. Then Lojacono and Aragona go to see the notary again. He is not alone.

Di Nardo and Romano go to see Nunzia's mother. She and her two sons are surprised by the visit and are on the defensive but one name keeps coming up as the policemen question them. At headquarters, Pisanello is studying a series of alleged suicides he is suspicious about.

Alex goes to see Nunzia by herself, to see if she can help her, but she gets an unexpected reaction from the girl.

After work, Aragona and Lojacono walk towards their respective homes together. Aragona says he is home, but is he? Pisanello goes home and makes tea, all the while telling someone (probably his wife?)about his day. Lojacono goes home and gets a phonecall from a certain Sonia...

Pisanelli goes to see Friar Leonardo and remarks how peaceful it is there in the cloister. Lojacono and Aragona go to see the head of Forensics and learn some new details about the evidence.

Forensics recovers an email that opens up some new avenues in the investigation. Lojacono and Aragona go see the notary at his workplace. Di Nardo's parents want to meet her boyfriend.

We get a glimpse of Francesco's home life in this segment. He has a lot of pent-up anger and doesn't have it very well under control. Lojacono and Aragona are following Miss Russo and have a little conversation about patience.

Lojacono has a conversation with Iolanda Russo and learns some new details. Later he has a meeting with his superiors.

The pressure is on Palma, and consequently on his team, to solve the murder alla svelta (quickly), but they haven't gotten very far. They are still in alto mare (a long way away).

Lojacono and Aragona scour the city to find a glass globe like the one that killed the notary's wife.

Having discovered who bought the glass globe, Lojacono and Aragona could easily figure out who had killed the notary's wife. They go to see the suspect.

Lojacono and Aragona, with De Lucia's recounting, are able to reconstruct the murder. We then learn what was written in the letter the notary's wife sent to him.

There's a press conference announcing the success of the investigation. Rather than singling out Lojacono and Aragona, Palma gives credit to his entire team, as well as to Dr. Piras.
