I've read the books, some are really good, some not so. Peter James writes short sharp chapters and the narrative moves quickly so they never fall into a lull, plus some very nasty villains. Many of the earlier books had the disappearance of his wife and the son he never knew as a riveting sub plot. Remember wanting to get to the bottom of that conundrum, he did string that out through most of the earlier books. Not sure what I think about the casting of John Sim although I've always thought of him as a good actor, just not sure if he fits in with my idea of Roy Grace. Wondering who will play Cleo. I will definitely tune in.
