someone stole my idea

On http://postsecret.blogspot.com/
I came across this postcard that said-
Everyone who knew me before 9/11 believes I'm dead.

I wonder who the person is.

I have half of, 'When the fourth monkey misbehaves' worked out in my mind. And it starts with the world trade center, and how it allows Cerric Scott to disappear.

And I find that someone else has already taken my idea, and actually done it!
