Imma and Calogiuri enter the cave where the footing is uneven and the two are thrown together. The police have found the boy and De Nardis is called into headquarters for more questioning.

We take a look at the Maserati Khamsin, produced during the oil crisis of the nineteen seventies. It didn't need much restoring and was particularly comfortable.

At the beginning, the Giussani sisters decided to hide their identities as women. Even so, it was not easy finding distribution. And there were other mysteries, as well, surrounding the early days of the iconic comic book, Diabolik.

For its time, the Ferrari Daytona Spider was incredible to drive, with its twelve-cylinder engine and impressive horsepower.

The creators of Diabolik had commuters in mind. They wanted to create something engaging that one could read in the time of a commute, and which was pocket-sized. We also discover why the name Diabolik ends with a K.

The revision of the Ferrari Daytona Spider continues. The result gives the car extra value on the vintage market.

Diabolik drives a Jaguar, but not an ordinary Jaguar. He is able to transform the car in order to facilitate escaping when the need arises. In a way, both Diabolik and his car wear masks and assume different identities.

As sometimes happens, something Pietro says, even in an intimate moment, reminds Imma of some detail in the case. Off she goes with Calogiuri to try for some new leads.

Every serious vintage car collector must have a Ferrari Daytona. Some of the characteristics of this car are described in this segment.

This series begins with Diabolik, the greatest criminal of Italian comics or fumetti as they are called because of the "clouds of smoke" (speech bubbles) present in comic strips. Fumo means "smoke." In this segment, various personalities describe the character Diabolik, both the good and the bad.

Imma manages to interview Stacchio's father, who is not exactly forthcoming. Back home, Imma gets complaints about her cooking and they listen to the news report about the missing boy.

We see the underside of a Ferrari as an inspection is carried out. Carmine Sessa, a classic car expert, talks about the Spider model and the Daytona model, which was built in a limited quantity, almost exclusively for the American market. Fun "fact": Some say the yellow color was named Fly, standing for "Ferrari Light yellow." The color was suggested by Fiamma Breschi (a close friend of Enzo Ferrari's). Fiamma means "flame" but she didn't want the color to be Giallo Fiamma "flame yellow" (named after her) and suggested "fly."

Leaving school, Valentina and her friend meet up with a certain Samuel who has a little present for Valentina. Imma and Calogiuri see Stacchio's friends and ask them some questions, with the pretext that Calogiuri had lost his dog.

The passion for vintage cars can become a real disease. Being the owner of a car and being a collector are two different things.

Imma gets some information from her "helpful" colleague and goes to Eustacchio's school to find out more. Viewers might recognize his teacher.
