It's clear Charlie would produce a masterful novel for all the reasons you cited, [dark]. So that's a given. And after the controversial reception of DMC, it's good to know the book is in the bag. But what of the publicity angle? At the moment, that might be a dilemma for IFP. How do you follow Faulks and something like the DMC centenary launch?
The only way to follow up Faulks (the mixed reaction to the book can surely be disregarded when you consider the sales figures) is with Faulks. But it's become obvious this simply won't happen.
The notion of "promoting" Higson, especially as his Young Bond series concludes so conveniently this year, seems like a natural progression. I can't picture it topping
Devil May Care in terms of hype (no future literary Bond release will enjoy the publicity that the Ian Fleming Centenary offered), but it'll come as close as we'll ever get.
The problem is, post-Fleming novels can pretty much only go in one direction, with Bond remaining a Double-0. Higson could turn out a handful of these, but the series would be in danger of going down the Gardner route of same old, same old (albeit in much more superior style).
It might be a bit late in this whole origin story fad (though the same was mused about
Casino Royale), but Higson writing about Bond's war years would be a fresh take on the character that could still fall within the "adult Bond" spectrum, while at the same time serving as a continuation of the exploration of Bond's pre-00 life.
(It's funny actually - when the Young Bond series was announced, one of my biggest reservations was the mystery of Bond's past being shattered. Now, not only have I warmed - in a big way - to Young Bond, but I'm excited about Higson continuing to flesh out Bond's past - because he does it so damn well.)
