This one's a strange Gothic horror and giallo hybrid. Meaning, lot's of cool 70's decor within an ancient castle. Very early on it's established that the main character is a prostitute killing psychopath, and yet we are supposed to care that he is being haunted by the ghost of his dead wife. Like a lot of these Italian films, the plot is an afterthought. Stylish visuals, lots of nudity and a brilliant Bruno Nicolai score are the focus here.
