Having just finished it myself, I tend to agree. The book certainly captures you in the beginning and for the first part I was gripped by a well written story. However, half way though it ran out of steam. There were no clues, everyone was suspected and for those that were charged there was no evidence. The remainder of the book was full of padding, with only minor links to the story and you kept on expecting a great revelation, a new theory, but there was nothing. Yes, a great disappointment.
