I've haven't done the sums for a while, but my novel Jackdaw - which, I make no bones, is a pot-boiler; but, I hope, a tolerably good pot-boiler - had made me £1,300 about a year ago, even given the niggardly percentages of Amazon. I do sincerely thank reviewers ;-). I deliberately wrote it as a movie, but alas, Hollywood has not yet bitten.
