Having faith in God did not mean sitting back and doing nothing. It meant believing you would find success if you did your best honestly and energetically.

I'm a great planner, so before I ever write chapter 1, I work out what happens in every chapter and who the characters are. I usually spend a year on the outline.

For success, the author must make the reader care about the destiny of the principals, and sustain this anxiety, or suspense, for about 100,000 words.

The research is the easiest. The outline is the most fun. The first draft is the hardest, because every word of the outline has to be fleshed out. The rewrite is very satisfying.

Thrillers have been traditionally very masculine books; the women characters often rather decorative.

World War II is the greatest drama in human history, the biggest war ever and a true battle of good and evil. I imagine writers will continue to get stories from it, and readers will continue to love them, for many more years.
