Il profumo della signora in nero/The Perfume of the Lady in Black (Francesco Barilli, 1974)
Although this film is too original to consider it a typical giallo, it's maybe the best film of this genre. Mimsy Farmer surprisingly combines adult feminity with childish delicacy. It is a Persephone for the sake of whom Hade will try to do everything possible. Brilliant cinematography (first take should be in encyclopaedia) fills movie world with surrealistic elements with allusions to Alice in the Wonderland; light transcendental features are more elegant than in Argento films. The end of the movie is very surprising and really unique - I don't want to spoil. This is a rare giallo that you'll remember for a long time as a whole, with unique athmosphere and penetrating visual themes (I would only say haunting). The director Francesco Barilli created only one more movie - Pensione paura (also giallo) that is unforunately absolutely unavailable.9/10
