From the Paris Review:
I began this novel as soon as I heard about the murders. I was vacationing in Hawaii and the murders ruined my vacation. The media went berserk over the murder of Nicole Simpson, the kind of ideal white woman—a Rhine maiden—one finds in Nazi art and propaganda, murdered allegedly by a black beast. It was a story that reached into the viscera of the American unconscious, recalling the old Confederate art of the black boogeyman as an incubus squatting on top of a sleeping, half-clad white woman. It was also an example of collective blame. All black men became O. J. The murders ignited a kind of hysteria.
