Also known as La Morte Accarezza a Mezzanotte, this is more of a Italian police story rather than straight up giallo. The cover art would suggest that this is nonstop wall to wall spiked-fist punching. Sadly, the spiked-fist punching is limited to one or two brief (although crucial) scenes. The movie opens with a silly drug use experiment that leads to hallucinogenic visions of the aforementioned spiked-fist punching murder. Our main character then spends the rest of the movie trying to find out what it was that she saw. They never really explain how she somehow forgot having witnessed a grizzly murder in the first place. But that's neither here nor there as far as this movie was concerned. Eventually, the bad guys are established and this all leads to a rather thrilling climax. I'll have to admit I was genuinely surprised by the plot twist in near the end.
