The Monster of Florence (2025) is a Italian crime series based on Italy’s most notorious serial killer case.

The series explores the investigation into 8 double homicides in the countryside around Florence between 1968 & 1985.

Although the killings to a long & complex investigation, with some individuals jailed, the original ‘monster’ has never been identified.

In the first double homicide, a 6-year-old boy, Natalino Mele, is in the car when his mother, Barbara Locii (Francesco Olia) is murdered along with her lover. With his father imprisoned, the boy ends up in an orphanage.

We see little of Natalino Mele for the rest of the series, although he does later testify that it was not his father who did the killing.
