I've hit the wall at 23%.  I'm doing my best to get the information out to the wider world, but I am going to need the help of others to do so. Among these others are you, dear reader.  If you have a fallow moment during your busy day, I'd be greatly indebted were you to use it to pass on details of the book to anyone you think might be interested, particularly among the older generations.  Your mums, your aunts, your dads, your uncles, your godfathers and mothers...  Here's a picture, because pictures make things more interesting.  It is a preliminary sketch by Gordon Stuart, for the portrait that is now owned (although not hung) by the National Portrait Gallery.
