We discover that Margherita Hack was a devoted fan of the long-running TV series, Un posto al sole [a place in the sun]. She explains why. Francesca goes back to Trieste and meets up with Eda who talks about having lived in the same house with Margherita Hack.

In this segment, Margherita talks about her choice not to have children and also discusses her position regarding God. She can't prove he exists nor can she prove he doesn't.

Even though Aldo and Margherita were very different in many ways, they came together in their skepticism. Towards the end of her life, Margherita couldn't move around much, but her brain never stopped going.

Margherita left a legacy of progress, both scientific and social. Perhaps she is still looking down on us, since an asteroid was named after her: 8558 Hack.

Il Commissioner Manara is an Italian TV series set in the Maremma (southern Tuscany), which centers on Luca Manara, an unorthodox and highly seductive, newly arrived police commissioner, played by Guido Caprino.

Commissioner Manara arrives on the scene of the supposed suicide. He questions a witness, and talks to the victim's doctor, and to the medical examiner, who turns out to be an attractive woman who has no problem with shyness.

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.

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.

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...

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.

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.

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.

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

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

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.
