Oh fantastic to hear he wants to. It's hard to tell from that piece whether these will actually happen or it's just what he would like to do.
I think it's the latter, although he certainly sounds very enthusiastic. If I were a Higson fan, I'd be feeling very heartened right now.
I can easily picture IFP commissioning Higson (or someone else) to write a series of slightly-less-Young Bond books, while another writer or writers work on a series of followups to DEVIL MAY CARE.
However, we shouldn't hold our breath for more Higsons. "Higson says he will take a break from Bond and write some original books of his own as he has a three-book deal with Puffin."
I guess it's a bit like the situation with Craig. Will Craig just do an origin story trilogy or quadrilogy, or will he carry on once his BOND BEGINS thing is done? Time will tell.
