Hi stan. In response to your question, is it any good?
i personally think that this book mainly covers already discussed theories and introduces the authors own view of events which in my opinion is quite frankly too far fetched to be credible.
however he does reference a diary left by mr wallace in which he makes reference to a book which he had read allegedly in the run up to his wifes murder. The author mr gannon then erroneously states that the author named in this diary "does not exist".
my own research has led me to believe that the book to which Mr Wallace alludes in his diary, is indeed a real book which was written by john kirkwood leys. and was intriguingly called "under a mask". this book was indeed published in the very year mentioned by mr wallace and adds extra mystery to this case.
i suspect that this may well be a cryptic clue accidentally left behind by mr wallace..........or it could be just another red herring!
i have so far been unable to ascertain exactly what kind of book under a mask is. but i suspect it may well have been a murder/mystery or thriller type book
i would be interested to hear anyone's thoughts on this.
