See OJ Simpson's guilty conscience at work.

Whenever a woman and a man who may have been her lover are found with their heads nearly sawed off by a knife, it is reasonable to suspect that woman's "ex-husband". If her "ex-husband" also had a history of beating that woman, it is evev more reasonable to suspect...Oh, heck! OJ did it.

Stuff: If I Did It - the OJ Simpson story

LOS ANGELES: Fox is to air a two-part interview with OJ Simpson at the end of the month in which he describes the 1994 murders of his ex-wife and her friend that he says he didn't commit.

The interview will be conducted by editor and book publisher Judith Regan.

On November 30, her Regan Books is publishing a book Simpson wrote with the working title If I Did It, Here's How It Happened. (Emphasis mine.)

Fox said Simpson's book "hypothetically describes" how he would have committed the murders. The special will air at 9pm November 27 and 29 on Fox in America.

Fox executives declined to comment about the show. In a statement, executive vice president/alternative programming Mike Darnell said: "This is an interview that no one thought would ever happen. It's the definitive last chapter in the trial of the century."

Fox is a subsidiary of News Corp, which also owns Regan Books.

A spokeswoman for Regan Books didn't return a phone call or an email seeking comment.

Simpson was acquitted in 1995 of the murders of Nicole Brown Simpson and Ron Goldman; he can't be tried again for those crimes.

In 1997, a civil court found him responsible for the slayings and ordered him to pay $US33.5 million to the victims' families.
