Now his wish has come true, and Michael Moorcock has been signed up to write one.
However, writing in The Guardian, Moorcock confesses to some misgivings:
When I was first offered the chance to write an original Doctor Who novel I hesitated. I felt I'd had enough fun and should settle down to the autobiographical stuff I'd mapped out for the next year or two. Then I realised that not only might I enjoy writing an original adventure, I could also take a look at what a character who has become part of our national folklore has come to mean. I could do, in fact, what SF does best for an intelligent, knowing audience. So I told my agent to go ahead and draw up the contract.
Now the vast potential of what I can write is beginning to dawn on me. Far from thinking in terms of fun I've become a little scared. All time and space is open to me. I have to mix comedy and melodrama while telling an epic adventure story featuring a complex protagonist capable of ranging across the entire multiverse. I'm increasingly overawed as I consider what I must live up to. Hardcore fans are already questioning my qualifications. I can only hope I'm equal to the job.
