We still don't know much about Marta Rivera's mysterious appointment, just that it was with the chief. A worker from the cheese factory shows up at the police station to give her statement.

Manara goes to see Casadio, asking for something he knows will be refused to him. He is actually in search of information on Rivera's earlier visit there. Buttafuoco and Barbagallo seem to think there is going to be a surprise party, since an assortment of cheeses was delivered to the police station.

Luca goes to see signora Martini in the hospital. When he gets back to the police station there is a secret ballot going on. Caterina shows up at the end.

Caterina talks to Luca in his office. Toscani brings a fax that looks more like a newspaper or a bed sheet, it's so long. Luca hatches a plan that involves Ada, Toscani, and himself. Ada's new guest seems to like her!

Manara and Toscani go on a secret mission. Luca takes a lot of risks, but gets some important information. Toscani catches up on some much-needed sleep.

After his night trying to outwit the dogs, Manara is not thrilled with Toscani. Ada gets flowers, and Marta gets a phone call.

Some officers slept through the night, others didn't, and this creates some tension at the police station. The mysterious truck driver is identified, and the analysis results of the milk used by the Soleri company to make cheese have come in.

The police squad goes to the Dairy to arrest Mister Soleri, and Manara hunts down Ivan Iordan.

Luca and Marta question the Bulgarian. Laura Martini suddenly remembers what happened to her on the night of the shooting. The report from ballistics comes through.

Marta and Luca discuss the latest dead end. But what if Mrs. Martini was not the target at all?

The moment has come to discover why Marta was the true target of the attack. And the moment has come for Luca to deal with his unorthodox confiscation of the Bulgarian's gun.

We recognize the name of the inspector from Rome. Marta recognizes the face. Later, at the farm hotel, Luca is on cloud nine getting ready for a romantic dinner with Marta, until Ada knocks at the door with some news. She milks it for all it's worth.

We're at the beginning of a new episode, and we see right away that Luca hasn't hesitated to find some consolation... But he has to rush to police headquarters where there's been a shock for Quattroni. Waiting for him are Raimondi (the new inspector), Rosmini, Rivera, and Toscani.

The murder victim, Mr. Ponti, was on his way to the police station to report a break-in when the crime occurred.

Three scenes: An article in the newspaper attracts the squad's attention, Manara questions the maid, and Fabrizio, the inspector, questions Manara.
