Beautiful Leticia Roman plays Nora Davis, a woman obsessed with crime stories who is on her way to visit her dying aunt, who’s being taken care of by good-looking doctor Marcello (John Saxon). After being distraught by her aunt’s death, Nora wanders alone through the streets of Rome and witnesses a murder. It turns out it was a victim of the Alphabet Murderer, a serial killer who kills people based on the first letter of their first name. Being the fan of detective stories, she decides to solve the mystery herself, for better or for worse.
This movie, along with Blood & Black Lace, is one of the most important films in the history of horror. It was the first film to give importance to the murder as much as to the buildup of suspense, and both were made by Mario Bava. This film is a very gothic piece set in contemporary times, the black and whites being as striking as they would be in Blood & Black Lace, and much more impactful than in his first masterpiece, Black Sunday. It would also be the first film, along with B&BL, to create the giallo genre that is so famous in Italy. A one of a kind film, packing terror, suspense, and humor as well. Go check it out.
