Needed a motivation for the climax of the novel. Being a historical fiction piece, I’m doing my best to keep all action related to actual events. Agonizing for days, to the point of distraction, on how to develop a better situation than I plotted out earlier, I absentmindedly searched for a better Edinburgh school to use as a backdrop. Lo and behold, didn’t the school pack up and move to EXACTLY the same place (and the same time/date) that my characters are all gathered around? What a huge rush this is, and makes working on this book for so long worth it.
