The author has been writing the book in Italy for the past month and will deliver his manuscript only a week behind schedule. A major Fleming echo will be the inclusion of Hannes Oberhauser, Bond’s climbing and skiing instructor whom 007 later referred to as “something of a father to me at a time when I happened to need one.”
Also, there is a title! While it can’t be revealed just yet, Higson reports that the title is very Flemingesque, and it is not The Shadow War, Diamond Rain, Dynamite Kiss, or any of the other working titles.
