well make and stylish while still ultimately make sense this thriller would work well for non giallo fan to get interested in the genre than the late argento entry which go overboard in all direction . for fan of these craze italian thriller and they will appreciate george hilton and the turn his character take and what he put through . the camera work be fresh with dash of graphic violence and odd and but appropriate choice and a good not overblown music score as well . the less you know about the story the good to make it work . the only thing lacking in keep this from be a great sergio martino direct giallo be that the story doesn not have that extra sexual or psychological and or both element to put it over the top . it more a routine mystery and the character be well define but live or die accord to the plot not accord to their own virtue and flaw . the recent dvd ( 2005 ) release be beautiful look and definitely the way to see the film and unless these ever get art house screening which seem unlikely .
