I had these two characters in my mind for a long time: two brothers in Haiti, one socially and financially more successful than the other, but the other, kinder and more heroic. I had it in my mind that someone should write about Haitian history and politics through fiction. The Duvalier era was tempting, because I couldn’t think of any story that brought up that slice of history, except maybe for Graham Greene’s “The Comedians.” Those were hard years of tyranny and censorship, when people were killed or imprisoned, or vanished without explanation. Haiti was dubbed “the nightmare Republic” back then, and still, it intrigued the rest of the world. That period in time was a goldmine waiting to be excavated.
