Where did you get the idea for your most recent book?
I was inspired first by the idea of the characters, who sprung into my mind almost entirely developed of their own accord. After that, the plot formed easily, based around the concept of predestination and prophecy. The inspiration for that came from a number of sources, but I'd say Macbeth was probably the most significant. Agatha Christie's mysteries also played a major role in the short story's development.
