“When you read the account of a murder – or, say, a fiction story based on murder – you usually begin with the murder itself. That’s all wrong. The murder begins a long time beforehand. A murder is the culmination of a lot of different circumstances, all converging at a given moment at a given point. People are brought into it from different parts of the globe and for unforeseen reasons. […] The murder itself is the end of the story. It’s Zero Hour.”He paused.“It’s Zero Hour now.”
