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.

Luca and Marta get interrupted by a phone call and Luca rushes off to where Buttafuoco is waiting for him.

Casadio is in a strange mood, due to some discussions with his wife. After Manara leaves his office, there are some imprevisti (unexpected events) that give him a new lead in the case.

Truth triumphing over falsehood is not only the theme of the fresco, but is also the theme of this segment. Marta and Luca zero in on their latest suspect.

We're at the end of this episode, where the famous fresco has been restored. Truth, symbolized in the fresco, is the buzzword of the moment but in ordinary life, it often remains hidden.

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.

In this rather bizarre way of meeting up, Luca and Marta clarify their feelings. Lara and her aunt catch up at breakfast. Meanwhile, there's a new murder to investigate.

Sardi is back in service. Luca goes out to look for someone who might have made the anonymous phone call about the death.

Luca is trying to stay out of the kidnapping case, but he is feeling pressure on several fronts to do something about it. Zia Caterina is not someone to whom you can easily say "no."

Luca takes some action on the case he and Lara are working on secretly. He goes to see Ginevra about the autopsy, and he also gets an interesting and gossip-worthy visit from Julie.

Lara manages to track down the jeweler through her colleagues in Olbia. The information she and Luca receive from him is surprising as well as concerning. At the same time, it allows them to consider the case to be officially theirs.
