I have no suggestion for a title, I'm not very good at that, but there was a book I read better than 20 years ago about serial killer Ted Bundy. I don't remember the title but I do remember the back cover. There was a picture of this very casually dressed, good looking young man with the caption "What does a serial killer look like?" The picture and the question are burned in my mind's eye and still strike me very powerfully to this day.

The identical premise could be applied to the child abuser because you never know who or where they are until you're faced with the monster.
