As with many British miniseries, this one obviously did not cost very much compared to a major motion picture or even a more mainstream television show. Nevertheless, the excellence of material and acting more than makes up for any deficiencies.
Dorothy Sayers' novels are mystery classics, and these adaptations remain true to her stories. Of course, one person's interpretation of a role may be very different from another's, but I was especially struck with the way Harriet Vane is portrayed. It's as if she walked straight out of the pages of the books. Edward Petherbridge is marvelous as Lord Peter, though he does not act the role in exactly the way I would have expected. He is a bit more mild mannered and sedate that I had envisioned Lord Peter to be. He is irresistibly charming anyway.
For me, some of the most important aspects of the books and films are their Britishness and their scholarly quality, both of which are amply in evidence in these adaptations.
Despite what appear to be penny pinching production values, this set is well worth watching and re-watching for its engaging plots and marvelous characters.
