The series was shot entirely in Turin. Many courtroom scenes were filmed at the former Curia Maxima on Via Corte d'Appello, a normally inaccessible location that was opened exclusively for the series.

Various courthouses additionally used the Palazzo Falletti di Barolo, while the Palazzo dei Cavalieri and the Church of Santa Pelagia were repurposed as the editorial office of the Gazzetta Piemontese and the autopsy room of the medical faculty, respectively.

Numerous scenes were filmed in the prison Le Nuove as well as at various squares and streets in Turin's city center, including Piazza Cavour.

The interior rooms of Villa Barberis, the family home of the Poëts, were actually filmed in Villa San Lorenzo in Racconigi, while the former Bona wool mill in Carignano was transformed into a chocolate factory in the film.

The Teatro Vittorio Alfieri in Asti served as the setting for the Teatro Regio of Turin for narrative reasons. For the third season, additional filming locations were used such as San Salvario, Stupinigi, Venaria Reale, Chivasso, Gassino Torinese and Sciolze, as well as the Tenuta Colombara in Livorno Ferraris as a juvenile detention facility.

The series reached approximately 85 million streamed hours within the first six months after its 2023 release and received a 100 percent critics score on Rotten Tomatoes.

The series was criticized by the great-great-granddaughter and great-great-great-granddaughter of the real Lidia Poët, among other things for obscuring her Waldensian heritage, the sexualization of the protagonist, and the abbreviated historical contextualization.

German critics repeatedly compared the series to other productions about women in male-dominated fields such as The Marvelous Mrs. Maisel, Godless, GLOW as well as Miss Marple and a female Sherlock Holmes; the song 'Misfit' by German-American punk rocker Riival was highlighted as a musical highlight.
