I know I wasn't going to blog again until 2011 - but this has to be seen to be believed.
I bought a book called 'Black Hand Gang' by Pat Kelleher (you'll have to wait for the full review).
The premise is that the 13th Battalion of The Pennine Fusiliers disappeared from the Somme battlefield on 1st November 1916. The preface to the book sounds very convincing and, of course, a total fiction as it tries to show that the story is based on fact.
To cap it all is a splendid way to advertise the book and perpetuate the myth is the No Man's World blog (http://nomansworldblog.blogspot.com).
Mind you a quick search of the net does throw up someone who believes - well, like they say one born etc.
Personally, I just think that it is an excellent way to publicise a book and pave the way for a sequel.
