在这部我亲爱的杀手犯罪/惊悚/恐怖片中,An unseen killer is murdering people that know too much in connection with an earlier unsolved case of a missing girl. I like the giallo genre, but this one by Tonino Valerii is laid back to the point of being tedious, a few gory set-pieces can't even help this film. The ending is horribly cliché and the film has one scene that featured a fully naked prepubescent girl that repulsed me. There is NO reason to put a nude eleven or twelve year-old in any film. EVER!
Following a mysterious decapitation (via mechanical digger) of an insurance investigator, Police Inspector Peretti is put onto the case. Slowly more people are found dead... a man supposedly commits suicide, a women is strangled, another attacked in her flat... but all the clues lead to an unsolved case of kidnapping and murder. Can Peretti find the murderer, if his major clue is a little girls drawing???
