I think Professor John Lonsdale is the author or co-author of this book.
In the original CBN article breaking the story, 'Kate Westbrook' was said to be a historian specıalısing in 'the emergence of post-colonial structures' . This seems to have been taken out of that story now (at IFP's request, so as not to give the game away, perhaps?) - or, at least, I can no longer find it. But I refer to it on the first page of this thread. The term 'post-colonial structures' is not as common as it might appear. A Google search on that exact phrase only comes up with 105 results. The fourth result is this
academic article. Note that Professor John Lonsdale, a historian at Trinity College, Cambridge, is on the panel of seven. Note, too, that in the article in the Times, Gideon Aiken admits that Westbrook is a pseudonym, but that she (or he, in my theory) is an academic at Trinity College, Cambridge. And note that Moneypenny's early life is spent in Kenya - Professor Lonsdale is arguably the world primary expert on the history of post-colonial Kenya. Google the exact phrase 'post-colonial structures' and the word 'kenya' and you get just 12 results. The top one is the above academic article; the fourth is this thread. Also note that Henry Chancellor, author of the other John Murray book on Bond due to be released, studied at Trinity College, Cambridge. Presumably history, as he now making his living a historian, so presumably tutored by Professor Lonsdale. Perhaps he was the contact between Lonsdale and IFP, and perhaps he helped with this book.
We know from IFP that this is a book partly set in colonial Kenya, written by a history professor at Trinity College, Cambridge who specıalıses in 'post-colonial structures' . Lonsdale is a history professor at Trinity College, Cambridge who specıalıses in 'post-colonial structures', especially regarding British rule in Kenya. Combined with the rarity of the precise phrase 'post-colonial structures' and its matching to him, I think John Lonsdale wrote the book. In the library, with a candlestick.
Perhaps CBN should email him to confirm?
