Really? i'm surprised. I thought lots of people interested in the case would have read the book!
That would be a reasonable assumption wouldn't it!? However, my experience is that those that want to condemn Sion will insist on doing so at any cost. Even if it requires ignoring any facts of the case, basic logic or applying the most basic bit of research effort.
Instead they will call upon the most spurious sources in order to bolster their claim. For example body language analysis of his Trevor McDonald interview 10 years after the event.
My closest association with the case is that I have some cousins that live in Little Common which is a few miles down the coast from Hastings. But as I have no links to the case means I have looked upon the unfolding of events with an un-impassioned viewpoint. if he were guilty of the crime, then so be it. But having looked at the publicly available information, it is quite clear to me that he is not and all attempts to prove otherwise have resulted in a complete disaster for everyone.
