Add to that supremely atmospheric set design, Jullian Jarrold's richly inventive direction, plus a terrific cast, and a slice of Yuletide TV heaven was born ." He found Riseborough to be the "star of the show", praising "the extraordinary blend of damage and menace she managed to convey", and judged that the "concluding part promises to be one to savour". </P> <P> The following day, O'Donovan found that in Part 2, "The biggest coup of the BBC's festive adaptation was that not only did it revert to Christie's original twist, but added considerably to it, making for a far more emotionally ending (... which ...) transformed a tale of moral turpitude and greed into something of much greater depth and contemporary resonance ." Again praising the "captivating" Riseborough, he found that "Toby Jones was also superb, all too credible as small - time solicitor John Mayhew", and added, "At every step, the acting (...) and skilfully - evoked atmosphere added layer upon layer of complexity, moral ambiguity and humour to what was at heart a simple premise". </P>
