Lucio Fulci, later known for his graphic horror films like The Beyond and Zombie, was years earlier a master of the Italian giallo (in the company of Argento and Bava) with films like A Lizard In A Woman's Skin and his masterpiece, Don't Torture A Duckling. This film has all the elements of the Italian mystery/thriller genre known as the giallo, but really pulls the viewers in by having each key character with a skeleton in his/her own closet. This keeps you doing as much detective work as the detectives in the film itself. Who is killing the young boys in town? The young rich woman who is so bored that she sexually taunts the eventual victims, the reporter who likes to tamper with a crime scene to get a better photo shot, the townswoman with a mentally disabled daughter, the local witch, the town idiot....the list goes on, and you have to keep mental notes like a true game to play and solve. The themes in this film are very daring and done with that perfect Italian style in the early 1970s. It is certain that no American studio would have even considered making a film of such strong content, and that is precisely why this is such a satisfying film (despite some unusual accent choices for the dubbing for the English language version -- You'd do yourself a favor by watching it in its original Italian language, as that is how the actors spoke) and will definitely have people discussing its meanings long after viewing it. As the saying goes, they don't make them like this anymore, so get a copy and cherish an important film like this one!
