So, this Holiday guy was murdered by mysterious Men In Black because he thought the Loch Ness Monster was a demon from a UFO?  This murder was accomplished when Holiday accidentally stepped on a spot where he had seen the mysterious Man a year before and was made to have a heart attack by some strange, paranormal means?  Uhhhh....

Sometimes healthy, active people have heart attacks.  What was his general health and diet like?  Did he have a family history of heart trouble?  Was he under stress from a divorce or some other cause unrelated to loch monsters or mysterious, secret government agencies?

 I read Redfern's book on the real MIB.  Great read.  Highly recommended.  

Karas:  The great thing about Redfern's articles and his book...he doesn't suggest conspiracies...he let's you draw your own conclusions.  There are a lot of odd stories surrounding Loch Ness and, if one is prone to believe in the supernatural, it would appear to be a source for the paranormal.  Aleister Crowley is one eccentric associated with performing rituals and residing in that location.
