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.

After working on the case together, the members of the team go home to deal with their personal lives. Not everyone is enthusiastic about going out for pizza with the chief.

The pizza party ends up just being Palma and Ottavia who make the best of it. Palma would like them to be on a first-name basis, but he is Ottavia's boss and she has trouble with that. He talks about dare del tu, which means addressing someone informally instead of dare del Lei, which implies addressing someone formally. It can still mean using someone's first name, but the pronouns (and conjugations) change.

As we begin a new episode, Valentina is in Latin class. Her mother, Deputy Prosecutor Imma Tataranni, has arrived at a new crime scene, and is exhibiting her usual, unique, and somewhat bizarre personality traits.

Imma discusses the dynamics of the case with the coroner. She also talks to the man who discovered the body. The subject comes up at dinner with her in-laws, and the TV is on so she watches the news broadcast about the case, too. Valentina has a new friend named Penelope.

Imma is having trouble finding the file on Domenico Bruno. True, it dates from fifteen years previous, but that's no excuse according to Imma. She also attends the commemorative event at Palazzo Lanfranchi, where Bruno's son pays a tribute to his father. Imma's ears perk up.

Imma talks to her old friend, Don Mariano, and he shows her the model of the deceased architect's pet project, never completed. Then, along with Calogiuri, Imma goes to the morgue where she is not welcome. Calogiuri's eye proves to be invaluable.

Imma finds out she was right about the "accident" being a homicide and goes with Calogiuri to see the architect's ex-wife and son. Calogiuri gives Imma some news she hadn't heard about.

Imma assumed that no one had done any work all day, but Diana let her know that the staff had actually done somersaults to get the information Imma required. The next day, Imma talks to the architect's son and learns some interesting facts.

Imma is furious about what she reads in the paper, but her boss tells her to calm down and wait for the trial. She also has to deal with a new police officer with a strong personality, but who is also quick-witted.

Matarazzo and Calagiuri hit a dead end in their first encounter at the University of Bari. Imma finally gets to consult the files associated with Bruno's disappearance fifteen years prior. Diana asks her for a favor she shouldn't have.
