'What Have you done to Solange?' (1972) – Massimo Dallamano.

The colourfully sordid goings on, and 'gettings-in' at all-girl schools have been a lurid mainstay of exploitation cinema for quite some time, and the singularly voyeuristic lens of ace cameraman Aristide Massaccesi maximises the gorier, more prurient aspects of poor Solange's especially gruesome misfortune! Heroically handsome, wickedly wiry P.E teacher Enrico (Fabio Testi) being emotionally estranged from his saucy wife, fellow teacher Herta (Karin Baal) seeks sensual succour in the delectably nubile bosom of exquisite Euro-starlet Cristina Galbo, and one of their furtive trysts is brusquely interrupted by Elizabeth (Cristina Galbo) partially witnessing the fantastically crude gynaecological slaying of a fellow student, thereby bloodily introducing one of the more popular Italian thrillers of the 1970s, and even with its iconic Ennio Morricone score, and ubiquitous Giallo trope of a black-gloved bath dunking, the forbiddingly grey British setting, and the unique presence of German icon Joachim Fuchsberger as the intrepid inspector Barth lends 'What Have You Done to Solange? far more of a Krimi vibe, with its illicit intrigue, plentiful nudity, and blood-stirringly sexy Morricone theme, maestro Massimo Dallamano's deliciously deviant Giallo is one sweetly sadistic slasher that always hits the sweet spot!
