Reviewing Part 1 in
The Daily Telegraph, Gerard O'Donovan decided, "Much of its sophistication is down to [scriptwriter Sarah Phelps'] multi-layered reworking of Christie's hit 1950s stage drama, that ekes every possible drop of emotion and mystery from what is a very simple premise. 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". 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[n] ... 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". Writing in the
Radio Times, Ben Dowell acknowledged "an ingenious plot twist – known to many Christie aficionados – but here given a few smart thematic manipulations by scriptwriter Sarah Phelps", noting her "major achievement is to make the First World War the emotional lynchpin of the whole saga". Dowell concluded by saying, "In the end this was a story of many loves—of Emily French's love for Vole, of Mayhew's unrequited love for his wife, even Janet's love for Emily. Pole star of course was the passion between Vole and Romaine which burns far too brightly. This was really compelling stuff". ==References==
