I read something earlier today on Google News. Essentially, they're trying to track down the source of the leak. The British publishing agency is pissed off at the American publishing agency since it appears to have leaked in the US. Apparently there was so much secrecy around this book that it should've been impossible for anyone to do this. I hope whoever did this is enjoying their freedom. They're going to be in a lot of trouble if/when they get caught.
