The Dark One
Auror
It depends of course on the story. My three published books all have the Incident at different points - one right at the beginning. One about 10 pages in (the hero receives a letter addressed in his own handwriting from a place he's never been while breaking up with his girlfriend over the phone, just after he was forced to resign from his job). The third, just published occurs about 60 pages in but there are numerous small incidents across several threads which give the story its momentum until a couple of threads come together and the main action explode off the page.
At least, that is my hope.
