"Cozzi brings an experimental edge to the film with his off-kilter visual style and repeatedly cross-cuts between parallel actions, contrasting a murder with a party, a frenetic chase sequence with a slow-burning police interrogation, a passionate sex scene with an horrific rape. The cat-and-mouse finale is all the more interesting because Cozzi forgoes the usual Dario Argento suspense mechanisms and instead mounts the action as believably awkward, ugly and slow. Luciana Schiratti's art direction combines well with the photography by Riccardo Pallotini to conjure one of the best looking giallo films while outstanding ensemble performances make the most out of the suspenseful script." - Andrew Pragasam, The Spinning Image
