Better on a rewatch.
First saw this years ago (maybe six or seven), I liked it but found it a bit lesser than some of Martino's other giallo efforts. I have to say I really enjoyed revisiting it last night.
I also recall thinking it was a shame Edwidge Fenech had a bob cut in this as opposed to her longer hair cut in other movies. Not sure why I thought that because she was rocking that cut in this flick. Beautiful woman.
