LOS ANGELES -- O.J. Simpson said a chapter in his unpublished book "If I Did it, Here's How it Happened," telling how he would have killed his ex-wife and her friend is "a fictional creation" mostly from a ghostwriter's research and not a confession.

He said it has so many "holes in it" that it should be clear he didn't write it.

The Newsweek account of the chapter has an angry knife-carrying Simpson being charged by Nicole Brown Simpson during a heated argument.

It quoted O.J. Simpson as saying: "Then something went horribly wrong, and I know what happened, but I can't tell you exactly how."

Simpson was acquitted of the 1994 murders of his ex-wife, Nicole Brown Simpson, and Ron Goldman after a yearlong trial. But a civil jury later held him liable for the killings.

The book was to be published on Nov. 30 by News Corp.-owned HarperCollins. News Corp. head Rupert Murdoch called off the project 10 days before, apologizing for any pain that it had caused the families of Ron Goldman and Nicole Brown Simpson.

A television interview of Simpson with the book's publisher, Judith Regan, was canceled as well. Regan was subsequently fired from HarperCollins.
