what about him?

"I couldn't quite decide what it was about him, but I was falling in love. At first it was terrifying what he could-and would-do to me. I lived in fear, realizing that I was a goner. But then it stopped being fear, and more curiosity, and then wonder. It soon didn't matter that he was the kind of man who would kill me without hesitation-strangle me, drown me, put a bullet right between my eyes. It didn't matter that I was dead to the world. It didn't matter that he would use me and then throw me to the dogs. No. There was something about him. What about him?"
