I look for two things when I am about to launch into a book. First, there has to be a dramatic arc to the story itself that will carry me, and the reader, from beginning to end. Second, the story has to weave through larger themes that can illuminate the world of the subject.

Well, here you had a city that was selling more cars than ever before, that had this wondrous music being created, that was so vital to the labor and civil rights of this country, and yet it was dying and didn't see it, except for some sociologist at Wayne State University who predicted that Detroit was losing population by a half-million by the end of that '60s decade, and that that trend would continue taking away its tax base.

I discovered in writing the biography of Bill Clinton that it is actually easier to write a biography of someone who is dead. Although you can't interview them, you have a fuller perspective on their whole life after they're gone and people are more willing to talk about them.

Detroit was an exaggeration of what was going on across the country. You could see the divisions, even within the Civil Rights Movement of that period. At the same time that Martin Luther King was talking about his dream, Malcolm X gave his most famous address in Detroit during that same period, "The Message To The Grass Roots," dismissing the notion of integration.

Originally, John Kennedy was going to come speak, and then Lyndon Johnson. Because it was October of '62, neither made it because of the Cuban missile crisis.

It was so crucial to the Civil Rights Movement that on June 23, 1963, Martin Luther King came to town, walked down Woodward Avenue with more than 100,000 people and delivered the first major public iteration of his "I Have A Dream" speech, two months before he did it in Washington.

It's hard to know exactly how people develop the characters they do. There could be people from humble beginnings that turn into jerks. Some characteristics are just part of that special soul of that human being.
