It depends on what the meaning of "IF" is

The fact the Rupert Murdoch's Newscorp scrapped plans to publish OJ Simpson's "hypothetical" account of the murder of his ex-wife, entitled If I Did It, has cheated us all of a glimpse into the scary recesses of his mind.

Now Newsweek magazine lets us in on some of what was to be in it including a chapter that certainly appears to be a confession to the crime but which Mr. Simpson unbelievingly claims is fictional.

I think it fits like a glove.
