To me, writing is a very physical process. I lay out the entire book with the two narratives side by side on my bedroom floor, and just get down on my hands and knees and start looking at it in that physical space. "Does this really follow from this? Should this be here or elsewhere?" I will literally cut the paper into paragraphs. I'll cut it into segments and move the segments around from one narrative to the other until I feel that I've found the natural structure.

Whenever I finish a book, I start with a blank slate and never have ideas lined up.

Great murderers, like great men in other walks of activity, have blue eyes.

I was never concretely aware of the extent of anti-Semitism in the United States and in the upper levels of the State Department.

It was so easy to disappear, so easy to deny knowledge, so very easy in the smoke and din to mask that something dark had taken root. This was Chicago, on the eve of the greatest fair in history.

Digression is my passion. I love telling the main stories, but in some ways, what I love most is using those narratives as a way of stringing together the interesting stories that people have kind of forgotten, and that are kind of surprising. The problem is, how do you pare stories away so that the book doesn't become a distracting jumble of material, and readers lose focus? In my experience, there's really only one way to do that. I pack it all in with the rough draft, then count on myself and my trusted readers to tell me what's good and what's not good.
