Thanks guys - all noted and I'll see what my local library has in.
By deviation I meant that I wanted the whole book to be reference to the war, and not visit other places at other times like some autobiography (for instance Dennis Sefton Delmers excellent autobiographical books (Trial Sinister and Black Boomerang) covering when he was a journalist during the war along with living in Germany/France before and Black Propaganda activities during WWII).
