To my considerable surprise I wound up the second draft of The Riddle of Billy Gibbs yesterday, only a week after finishing the first iteration. Usually it takes me six weeks to two months of rewriting between drafts. In this case, however, it seems that the first draft was pretty close to what presumably will be the complete novel. That's a first at my house. At least I think so.
The small corps of reader-critics to whom I send my second drafts, however, probably will have different ideas (including objections) that I'll have to address in the third and final draft.
It would be nice to think that after six novels I'm finally getting the hang of mystery writing.
But . . .
