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.

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.

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.

You also had in Detroit that summer, an early variation of Ferguson. A black prostitute was shot in the back by police. And all of the efforts that a very progressive police chief and mayor of that period had put into trying to restore race relations started to fall apart again, and you could see that unraveling for several years until the riots or rebellion of 1967.

Well, there is something beautiful about ruins. I mean, in one sense it's not that different from going to Rome and looking at the Forum. But it's changing. It truly is. I'm optimistic but skeptical.

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.

And then the industry itself was so cocky about what they were doing that they weren't seeing what was coming on the horizon with Japan and Germany and other places that were building smaller cars.
