I remember watching a movie when I was a kid.  It was a color movie, on TV, about a serial rapist.  Unfortunately, I only remember that he would get into the woman’s house by going through her window then raping her.
I also remember that it was a very dark movie—you could hardly see what was going on but you knew what was going on. I’m sorry that I don’t remember any actors or actresses, I was a kid when I saw this on TV.  I’ve searched everywhere—this movie has haunted me for years.
