Il sesso della strega (1973)

Sir Thomas Hilton is ready to die.Around his death bed all the nephews gather as they want to attended the funeral and hear his will. The assets will be shared equally except for his daughter Evelyn, who is out. During the night one of the nephews named Johnny is violently murdered with an old medieval mace and there are many suspects.
Angelo Pannacio's "The Sex of the Witch" is very sleazy and features plenty of sex. The plot deals with incest,drug fueled sexual orgies and various other perversions. The soundtrack by Danielle Patucci is beautifully melancholic and the use of yellow and orange colors certainly enhance the atmosphere. Camille Keaton of "I Spit on Your Grave" fame has a significant role as one of the nephews.
