While we were walking around, we came to the Catholic church, and we saw that some people had set fire to carpets and banked them around the rectory, which was made out of wood. They knew every fire truck on the South Side was going to be in the park, that the rectory would just burn to the ground. Our one little act was putting out that fire.

Organizer is kind of a grand term for what I was doing. I answered an ad that the Presbyterian Church of Chicago put up on college campuses. I was at the University of Kansas, and it's somewhat relevant to my life and work that I'm a Jew. But they weren't doing a religious litmus test. They wanted energetic, civil-rights-committed college students to come help them run some summer programs.

I grew up in conservative rural Kansas in the 1950s when it was expected that girls would not have a life outside the home, so educating them was a waste of time

The rich are different than you and me: they have more money and they have more power.

I had a fantasy as a child that I might be a writer someday. I always thought that meant you went to New York or Paris. But after that intense summer, I never thought that I wanted to live any place but Chicago. It also made me see what the stakes were in the civil rights movement. And it made me see what real hatred was like and the forms that it took. But it also made me understand how powerless ordinary people feel in their lives.

But what I've learned is, when your adrenaline is flowing, you can do a lot. I'm not very physical, but once some punks were trying to break into my house and I chased them down.

I spent 10 years as a marketing manager. I've found my experience in the financial world invaluable background for writing about white-collar crimes.
