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.

And that John F. Kennedy uttered the first variation of "ask not what your country can do for you" in Detroit on Labor Day in 1960. So Detroit was really central to Democratic politics United States. Every Democratic candidate would start their fall campaigns in Cadillac Square.

There was a precarious balance during those crucial months between composition and decomposition - what the world gained and what a great city lost. Even then, some part of Detroit was dying, and that is where the story begins.

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.

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.

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.

Well, there were several things. One was that the industry itself built in Detroit was abandoning the city - taking factories elsewhere, the corporate headquarters elsewhere.
