Agatha Christie's The Seven Dials Mystery: A Netflix Adaptation Lacking Bite

England, 1925. Lady Eileen Brent, known to all as Bundle, and her mother Lady Caterham organize a lavish masquerade ball at their opulent country estate, despite the financial difficulties following the Great War. Amidst dancing and revelry, a group of friends decides to play a prank on Gerry Wade, known for being a heavy sleeper: eight alarm clocks are placed in his room, programmed to ring one after another. The next morning, however, Gerry doesn't wake up. Only seven of the eight alarm clocks remain on the bedside table, and the young man is found dead under mysterious circumstances.

While the police quickly dismiss the case as an accidental death, Bundle – an heiress with insatiable curiosity and very fond of the victim – decides to investigate on her own. Defying her mother's authority and the pragmatism of Inspector Battle of Scotland Yard, the young woman delves into a muddle that soon proves to be larger and more dangerous than expected, involving secret societies and state secrets capable of jeopardizing the nation's destiny.

Almost a Century and It Shows

Chris Chibnall, creator of the celebrated Broadchurch and showrunner of Doctor Who between 2018 and 2022, returns to crime drama with this three-episode adaptation of the novel I sette quadranti (The Seven Dials Mystery), published by Agatha Christie in 1929. A return to origins that, at least on paper, promised a lot: the meeting between a screenwriter skilled in constructing layered mysteries and the queen of crime seemed like the ideal pairing.

However, partly due to the serial format, not everything works as it should. Diluted into three episodes of about fifty minutes each, a story born as a light-hearted thriller struggles to sustain the duration. Christie herself considered The Seven Dials Mystery a "minor" novel, one of those works written with greater lightness and without the need for particularly elaborate plots or continuous twists. An approach that today, in the face of an audience accustomed to increasingly complex and exaggerated whodunits – Knives Out above all – inevitably shows its weaknesses.

The main issue is the pacing. The story would probably have withstood the format of a feature film or a one-and-a-half-hour "television movie" with fewer repercussions, whereas here the total duration almost doubles, with passages dragged out and redundant dialogues that progressively dampen the tension. Perhaps a freer adaptation, less respectful of the original structure, would have been better, because fidelity to the text, in this case, becomes a limitation rather than a strength.

The Faces at the Heart of the Mystery

Nevertheless, the good work of the main actors must be acknowledged. Mia McKenna-Bruce and Martin Freeman bring Bundle and Superintendent Battle to life with the right verve, characters who had already appeared in a previous Christie novel never adapted for the small screen. The absence of that background is felt, leaving some grey areas in their relationship, so much so that the most incisive figure ends up being Lady Caterham, played by Helena Bonham Carter, although relegated to a role that, in fact, is closer to a substantial cameo.

A further limitation is represented by the large supporting cast. With many characters introduced hastily and little room to characterize them, it becomes complicated to orient oneself, and the game of hypotheses – fundamental for any mystery – loses effectiveness. When the truth finally comes out, the revelation is predictable, despite a finale set on a train that tries to liven up a staging that had remained rather stiff until then. If the series achieves good viewing figures, a second season already seems around the corner, with the very open epilogue ready to relaunch the adventures of Bundle and Inspector Battle.
