Modern Metaphysics

I met an author of detective fiction once who pondered aloud about the relationship between fiction and what passes for real life. His experience was profound.
As he was reading the galleys of his first published detective novel his own partner was murdered. Even the instrument used to kill his partner was exactly the same as in those first galleys. He had to change that. The published book has a different murder weapon than the original galley proofs. Both he and the publisher thought that the change had to be made so that comment in the small theatrical community where they both lived was kept to a minimum. 
We are all conscious that there is a relationship between fiction and the future but rarely have I come across so clear and intimate an example as this one.
I have pondered this for some time, for it does seem that other realities abound. I wonder too about the realitionship with time that seems connected with such occurences.
