I was working on a satirical novel about a charismatic preacher who takes over a small Indiana town. Then I remembered Jim Jones was from Indiana and Googled him. I learned that the FBI had recently released all the documents that agents collected from Jonestown after the massacre - over 50,000 pieces of paper and almost 1,000 audio tapes. I started reading the files and couldn't tear myself away; I find "true" stories inherently more powerful than fiction.

I think the folks who joined Jim Jones's church did so because they truly believed in his stated ideals of racial equality and social justice. That's why he was able to convince one thousand of them to immigrate to the jungle of Guyana. Although history has stigmatized Jonestown residents as the people who "drank the Kool-aid," I'd argue that they were noble idealists. Furthermore, they were murdered. They didn't willingly drink poison - they were forced to do so at gunpoint. They sought the ideal, only to have their leader horribly betray them.

As kids, my brother David and I longed for acceptance. We were desperate to belong. We would have been thrilled to see the pews of Jones's church in San Francisco, with blacks and whites sitting side by side. And Jim Jones's sermons on social justice and equality would have had much greater appeal to us than the soporific morality tales we were accustomed to hearing. Jones promised real racial equality. He promised to create a truly equal community in the jungle in Guyana.

There were several parallels between Jonestown and Escuela Caribe. Both places used isolation to control a large group of people and censored their communication with the outside world so their loved ones wouldn't know about the rampant physical abuse and misery of the residents. I think the worst fallout, in both cases, was the living in constant fear, witnessing other residents get assaulted and worrying that you'd be next. That's where Post Traumatic Stress Disorder comes from.

To be honest, I didn't want to get inside Jones's head. Every time I wrote about Jim Jones I practically had to tie myself to my chair to force myself to do it; I hated him so much. He wanted to go down in history and he did. He's had hundreds of books and articles written about him. I was much more interested in the stories of the rank-and-file members of Peoples Temple, what drew them to Jones, and what they did once they were trapped in Jonestown and realized Jones was intent on killing them.

I was pregnant with my youngest child at the time, writing about mass death while I'm growing this precious little life inside me. Here I am, worried about everything I eat and drink and whether I walk past a smoker, and meanwhile I'm writing about an event where almost three hundred children were slaughtered. Most were never identified and are buried in a mass grave in Oakland. It was surreal. But it felt good to give Jim Jones's victims a voice, especially ordinary church members.

My parents subscribed to both Time and Newsweek and in 1978, I remember the covers of both that December were of the bodies in the jungle. The fact that many of the people who drank the cyanide - as well as Jim Jones himself - were originally from Indiana, that stayed with me. I wanted to know why they did such a baffling, horrendous thing, why they would kill their children.
