Query: Powerful story; good book.

After seeing the movie, I read this book and it filled in a lot of missing pieces. (what happened to the different players, who were the cops responsible in NJ, did Rubin and the Canadian lady have anything more than a friendship, what happened to Lazarus ...etc).I couldnt put the book down and found the story even more disconcerting in book form than the movie; since actual names and people were portrayed (in the movie for instance the changed the evil cops name...).In the book there is also an update (since the movie) to what has happened to Rubin et al, although, curiously, no mention of the movie itself.
