He then taught English and Drama where he had even less time to write (and not much time to actually live) though he did manage to produce the odd short story.

He lives in Malvern and recently gave up teaching so that he would have time to write the next two novels in the "Moon King" series. He hopes he won't starve to death before he has achieved this.
