I started reading this yesterday and there is some very interesting dialogue in the first chapter. Some of the descriptions of JBs behaviour I have never read and it comes across as almost incriminating at times due to the fact that he goes from being overcome with emotion to seemingly fine. In general it has so far been intriguing
The Wilkes book in some ways gives the most balanced account of the murders. We're told that Wilkes did extensive research and interviewed a number of witnesses and that's evident when you read this book.
Yet Wilkes does not attribute his quotes or information. Though, to be fair, none of the books about the WHF murders do this. This lack of attribution is a weakness in all of these books, in my opinion.
Wilkes seems to me to begin from a 'guilty' perspective, however by the end of the book he reaches the conclusion that the question of who killed five members of Jeremy's family is 'too close to call'.
