With its soft-toned accompaniment and gentle lyrics, "Il regalo più grande" ("The Greatest Gift") sung by Tiziano Ferro, creates a special mood. It was released as a single in 2009 and in that year became fifth on the list of best-selling songs.

Back in the days when people traveled on horseback, Al Biondo Tevere was a convenient rest stop just outside the walls of the city. People would feed and water their horses, and trade what was in their bundles of food with their fellow travelers. Later, it became a proper restaurant and many famous people became regulars, including filmmakers, Pasolini and Bertolucci. Signora Giuseppina shares the story.

An important new element in the investigation comes into play: some romantic letters found at the victim's house. Lara is comparing the handwriting to that of the note found next to his dead body.

The great Luciano Pavarotti, accompanied by a children's choir, sings the most famous Italian Christmas song of all, Tu scendi dalle stelle (You come down from the stars), composed in 1754 in the province of Naples. Buon Natale!

With the information given by Ginevra, Luca and Lara go to the pharmacy to find out about recent sales of two drugs. When combined, the drugs are fatally poisonous. That same day the funeral takes place and the whole town is there. Manara takes advantage of this to look for new suspects.

At work, Lele is preoccupied with the Cetinka problem, but then his superior gives him new things to worry about. And if that weren't enough, Grandpa Libero calls him about more missing money and more suspicions, pointing to Giacinto of course.

The island of Lipari is famous for having one of Italy's most important archaeological museums. This is largely because of the numerous shipwrecks that have been excavated. A particularly evocative aspect of Lipari is the presence of sea stacks that emerge from the water in a variety of shapes.

Marika and Anna take us to a famous restaurant on the banks of the Tiber River in Rome. Tune in to discover what's so special about it. (It has to do with movies and movie stars.) And... maybe you can guess what pasta dish Anna is going to order!

Marika and Anna take you to a shop where they make and sell fresh pasta. Have fun!
