A spokesman for Bloomsbury said: “we have a litigation specialist poised 24 hours a day, seven days a week to deal with any breaches. It is our intention to enforce the embargo vigorously and seek an immediate injunction if required.” While experts put the cost of all this at £10 million, the lengths to which publishers have gone are not surprising.
Considering there is such tight security when it comes to this book, I doubt anything really important was leaked. As for someone having a copy of the book and posting it on the internet, the publishers have all copies and are only transporting it to retailers on Tuesday, meaning NO ONE can possibly have a copy. Don't believe the spoilers. I typed Harry Potter Spoilers on google, and the first three links gave me three different endings.
