While the countess points out where she found the cartridge shell, Manara and his squad find blood spatters on the floor of the cellar.

A man found dead in the middle of the road, the cyclist who found him, and Commissioner Manara who as usual, is the center of attention.

We begin a new episode of Commissioner Manara. Lara is bedridden with a fever, and there is a missing person reported at the station. And if that weren't enough, someone was found dead by the side of the road.

The Lenni case will be filed as consenting manslaughter, in view of the fact that he was coerced. Commissioner Manara asks again about being transferred but doesn't get very far.

Dr. Masini confesses to having falsified his diploma in order to practice medicine, but reveals some surprises about the death of Lenni.

Commisioner Manara and Lara continue their investigation, interviewing Dr. Di Censi, whose answers enable them to make an important connection with a note they'd found of the late Professor Lenni's. They go to Dr. Masini's office and find him just about to leave.

It turns out Lenni's will contains some surprises. Someone important is excluded completely and another person, quite unexpectedly, is included. Meanwhile, Caterina is puzzled by Doctor Masini's behaviour the day of Lenni's death.

Manara visits the dead professor's daughter and it becomes ever clearer to Manara that the mother's alibi won't hold.

Lara Rubino visits Lenni's villa and finds that his wife has broken in. Manara uses his considerable charm on a vet.

The autopsy shows that the victim couldn't have pulled the trigger, but Manara's boss insists on suicide. Manara and his team have other ideas.

From the gardener, Michele, we learn that the dead professor was not well liked. Rubino lets us know about her soured friendship with Manara at the police academy.

Manara arrives at his hotel, and the clerk is curt with him until she learns he's the new commissioner. Manara and the deceased are the topics discussed by Rubino and her aunt.

Rubino, the new inspector, can't stand being in the same room with Manara. And when he doesn't even remember why, she really gets angry. But then they get some interesting news from the morgue...

Commissioner Manara meets up with Lara Rubino, his old classmate from the police academy. She's less than happy to see him and slaps him right across the face.

Manara meets his new boss and from the outset there's tension. We learn that Manara was transferred to his new post because of an affair between Manara and the wife of his former boss.
