Bava jump–started the Italian giallo genre, thrillers laced with horror and lacy sex, with this stylish noir about a young American woman pursued through Rome by the "Alphabet Murderer." After witnessing a brutal slaying, Nora, a naïve and sheltered vacationer, is thrown into a tangle of disbelief. In Hitchcockian fashion, which goes far beyond the titular reference, all is suspect as delusion and duplicity bang up against a string of unsolved crimes. John Saxon portrays Dr. Marcello Bassi, the romantic interest who would rather play dottore than detective. Spying eyes, menacing shadows, mistaken identities-the glory that was Rome becomes a beautifully composed labyrinth of portentous piazzas and apartments, including one where an ensnaring spiderweb protects our virginal visitor. Originally butchered as the U.S. release The Evil Eye, this gorgeous giallo has looks that can kill.
