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.

At police headquarters, everyone is thinking about what they will do when they get off work, but then there is a phone call that changes everyone's plans. A fall onto the rocks by the beach, a book with an intriguing design, and we're off to a new episode with Luca Manara.

The investigation begins. Manara and Rivera go to see the victim's wife, while Toscani calls a tow truck. Then all hell breaks loose in a house nearby, where there's been a gas leak.

The autopsy report comes, and Manara goes to talk to the victim's widow. Marta goes to talk to his lover. Marta gets a phone call, and her colleagues realize, with surprise, who her father is.

Both the victim's wife and his lover are questioned at the same time, one by Luca, and one by Marta. Each has a very different memory of what Fello was like.

How good of a painter was the victim? Not all the people who knew him have the same opinion. Luca and Toscani go to see the picture framer and learn a few things.

Luca and Marta finish their conversation but get interrupted. Later, Luca looks after Alice so that Toscani and Sardi can have an evening out. While he is there he makes a phone call.

While having a drink with Ginevra, Luca notices a painting that looks like it could be one of Fello's. The next day, as he is waiting to talk to his boss, Raimondi shows up and asks him for a favor.

Casadio says the case is clear to him, and doesn't seem very open to Manara's theories. Marta talks to Cristina and finds out Fello had recently bought a camera he urgently needed.

Marta and Luca keep looking for the camera. They go to the house Di Maggio had wanted to have restored but now has to sell. They also return to the scene of the crime.

Luca, Marta and Di Maggio go to his house and make a discovery. Little Alice is making a fuss and Luca comes to the rescue. Raimondi and Marta have a serious talk.
