A Doctor in the Family is a television series that has been broadcast on RAI 1 since 1998. Ciccio Martini, a young boy, introduces us to the members of his big family.

"We have a missing Count, a cellar full of blood, a mysterious Frenchman..." is how Commissioner Manara sums up the investigation to this point.

Anna recounts the story of Tosca, an opera singer who is in love with the painter Cavaradossi. Puccini's opera was first performed in Rome in 1900.

Lara's aunt visits Malvina, bringing along her snooping dog. Together they find a ripped up business card in a wastebasket.

The Commissioner and Lara question Count Lapo's oenologist, one of the last people to have seen the Count.

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

Anna tells us the tragic story of Cio-cio-san, protagonist of Madam Butterly, an opera by Giacomo Puccini, libretto by Giuseppe Giacosa and Luigi Illica. The opera was dedicated to the Queen of Italy, Elena di Montenegro.

Manara and his team are still looking for the hit-and-run driver who killed the tramp, and investigating the vineyard owner's disappearance. Lara gives Manara a clue as to why she's still angry with him.

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.
