Red Dragon too for the same reason. The way he writes really gets you into the characters mind. I still get chills thinking about the part with the reporter in wheelchair. He describes the victim thought process as he's dropped off outside his office building. Even after all the killer did to him, he starts thinking he'll be set free, and you start to think that too, ::: spoiler spoiler
just moments before he is set on fire and rolled down the hill.
Another one that really distributed me was when he describes the killer just watching a family in their house. They are completely unaware that he has been watching them and that they'll be his next victims.
I read that book 25 years ago and I still remember vivid details of it.
