The Cadfael Mystery! shows were indeed unlike the books (as with the James Bond movies, they took elements from several books and strung them together or mixed and matched them.) But unlike James Bond, the Cadfael series was truly beautifully done. But I've always found Cadfael more interesting for the settings than the stories. I mean, when we meet the person the Long Arm of the Law (in the form of the fortunately open-minded Hugh) is after, well, if Brother Cadfael likes him, he's not guilty. But one keeps reading them anyway, like little Cadfael McNuggets. They are character and setting-driven, rather than plot-driven, IMHO.
