The Fiddler's Gun by A. S. Peterson "Fin jumped and held the hammer up as if she was ready to throw it. She was kneeling in the grass beside the front door of the chapel and had managed to work the first of the three front steps loose. When she realized it was only Peter, she smiled and motioned for him to be quiet."
