I received several comments on a recently published work because it in some ways parallels events in my life. The comments center on the idea that if a certain person of my acquaintance comes up missing, I would have to be suspected, given the plot of the story.
Life is unfair, unbalanced, and unjust. People we all know should be punished aren't. Writers have the luxury of deciding whether justice will reign and how it will happen. And we don't even have to give DNA samples afterward.
