Marta proves herself to be smart and intuitive. This leads to a new perspective on the case.

With Lara gone, Luca seems to want to make up for lost time, and flirts unabashedly with all the women he comes into contact with. Fortunately, he also gets down to work, and has a man to man talk with one of the suspects.

Little by little some of the suspects are being eliminated, but the situation is far from clear.

Officers Barbagallo and Buttafuoco get some good evidence, but Manara doesn't quite appreciate their guessing-game humor. He goes to question the new suspect.

Luca Manara and Marta Rivera are both curious about each other. But Marta has better luck. Manara and Toscani go to see the victim's husband, who learns some things about his wife he hadn't been aware of.

Lara isn't around, but her presence is felt by everyone, in different ways. And they all want to know how Luca is feeling about it, but he's a closed book and just focuses on the case.

Marta goes for a ride on Luca's motorcycle as they look for a mysterious South American barman. Ginevra meets Marta and seems to like her a lot.

Interviewing the husband of the deceased was uncomfortable, since there were delicate questions to ask. Back at headquarters, Luca learns whether or not it was his hair on the pillow, and Marta has some insights that make the others roll their eyes.

Manara gets to run the case, and the new inspector arrives to welcomes that range from very warm to very icy.

There's a departure, for sure. Lara gets on that big blue bus and says goodbye, but there is an arrival, too.

We've come to the moment of truth for Luca and Lara. Neither of them is happy, but they both know, deep down, that it's the right thing to do.

In the case, the sad truth comes out. Luca and Lara are both very somber for their own reasons. The only happy person seems to be Toscani who discovered traces of blood on the cane.
