Clear and Convincing Proof by Kate Wilhelm

2.0

You do not start out a mystery from the perspective of the killer and give absolutely NO indication that the person has the capability to kill. That is literally the First Commandment of Detective Fiction: The criminal must be someone mentioned in the early part of the story, but must not be anyone whose thoughts the reader has been allowed to follow. Wilhelm, who teaches a writer's workshop, surely knows about the Commandments. It almost makes me wonder if Wilhelm broke the first commandment out of hubris.
