Diana Rigg is back in top form as the larger than life (but firmly grounded on human misdemeanours) character of Mrs. Bradley. Neil Dudgeon and Peter Davison provide a solid counterweight to her flights of fancy and intuition, which is a bit ironic for Davison - who made part of his career out of playing Margery Allingham's super-sleuth(and upper class to boot) Campion. I have only had access to three episodes, but they are lengthy enough for characters to develop and for the interplay between them to become a given. I think the acting, art direction, sets and music will take anyone to heaven. This is way above (& beyond) any Agatha Christie screen adaptation - and Diana Rigg *is* Mrs. Bradley, much in the same way that Jeremy Brett *was* Sherlock Holmes. Bravo!
