It seemed that I could tell the whole story pretty powerfully in those 18 months between October of '62 and the spring of '64 when they were all at their peak. And yet you could see some of the shadows of Detroit's demise coming.

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.

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.

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.

My favorites are Stevie Wonder and Marvin Gaye, but those are a little off in terms of getting Detroit right on the head. But of course, you know, "Dancing In The Streets." You can't forget the Motor City. And we can't forget the Motor City.

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.
