After questioning the bus driver, Luca isn't convinced he's the murderer. Meanwhile, Tiziana doesn't seem to be taking house arrest very seriously.

Rivera and Manara review the surveillance video of the bus and see something new. Meanwhile, Tiziana seems to have fallen in love.

Marta and Luca are getting closer to the truth and gradually find more pieces to the puzzle, thanks, in part, to some good police work by Barbagallo and Buttafuoco.

Marta and Luca manage to figure out what happened, and Luca tells the story to his boss, Casadio. Manara gets out of the office with the excuse of a physical therapy session.

With some prodding by Marta, the scene where Luca is lying on the ground and says "I love you" comes into focus for him.

Manara meets first with Casadio and then with Raimondi, but doesn't get his answers answered to his satisfaction. But then, he gets a phone call about a dead body, so he has to race off.

Rosmini takes a look at the body. Manara talks to the woman who found the dead man. He goes back to the police station where the new member of his squad is waiting for him.

As Lara and Luca go to question the victim's wife, it turns out a third dog has gone missing. Luca can't help but notice how self-assured Lara has become.

The card that came with the flowers for Lara contained an important message. One of the people Luca wants to question comes to the police station of his own accord.

Lara plans to go and stay at her aunt's house, though Caterina is gone. Luca is clearly preoccupied when he goes to the morgue to talk to Ginevra about the autopsy.

Manara's team goes to the hunters' bar to find Nino La Martina and have some lunch at the same time, perhaps. There was perhaps a bit more action than they were prepared for, but, of course, that goes with the job.

Nino La Martina is questioned by Luca. Toscani and Lara's injuries are being taken care of, but Luca offers to take Lara to the emergency room. She has another suggestion to make.

Ada and Pio go dancing, but when they get back to her place, they get an unexpected interruption. A bit later, Ada innocently reveals some new elements to the case, and Luca comes back to life from his doldrums.

We see the difference between Luca's by the seat of his pants investigative technique and Lara's more scientific technique. They both have their place, but in this case, Luca's is more effective. The team makes some headway, even if it is just to eliminate some suspected murder weapons.

Manara has an unusual conversation with his boss, Lara has a phone conversation with her aunt, and Luca and Ada have a conversation about relationships.
