Originally the background history about Will’s parents, their meeting and his father’s end, appeared near the start of the novel. Dr. Harrod suggested I move the info to a latter place and dole it out in small bites, and begin with the wayward boy dialogue in the hostel. One major change to that text was the motive of Will’s father. Initially, he was booby trapping a bridge with the intent of setting off a bomb on parade day as the Orangemen crossed. After due consideration, I decided this placed him in an unfavorable light in the role of the aggressor, so I changed his mission to a defender against a sniping attack.
