New British series set to premiere on Netflix on January 15, 2026, Agatha Christie's The Seven Dials Murders is an adaptation of the novel The Seven Dials Mystery. Created by Chris Chibnall, a prominent figure in British television crime dramas, the show falls within the genre of historical detective thrillers. It stars Mia McKenna-Bruce, Martin Freeman, and Helena Bonham Carter, offering a modern reinterpretation of a classic by the renowned author.
England, 1925. In a lavish country estate, a glamorous gathering takes a dark turn when a cleverly planned joke seems to result in an unexplained death. What was meant to be a lighthearted prank quickly spirals into a tangled web of family secrets, deception, and manipulation. The stately, refined ambiance of the English aristocracy sharply contrasts with the seriousness of what unfolds.
At the heart of the story is Lady Eileen “Bundle” Brent, a spirited and independent young woman who’s not quite suited for the role of detective. Her innate curiosity and defiance of societal norms push her to delve into the dark corners of the estate and its inhabitants. This investigation becomes a transformative experience for her, upending her life and uncovering a conspiracy far more extensive than anyone had imagined.
This adaptation continues the well-established tradition of bringing Agatha Christie's work to the screen, but with a streamlined format of three episodes, each roughly 50 minutes long. Chris Chibnall opts for a brisk storytelling style, where the detective story is seamlessly intertwined with a social portrait of England in the interwar years.
Historical reenactments take center stage, showcasing aristocratic mansions, bucolic settings, and carefully crafted costumes. The series also highlights the character of Bundle Brent, often seen as unconventional within the Christie universe, emphasizing her modernity and vitality in a world that remains highly traditional and rule-bound.
With its tone blending suspense, drama, and subtle irony, Les Sept Cadrans d’Agatha Christie appeals to fans of classic puzzles and period detective series. While it can be compared to other recent adaptations of the author, it stands out with a sharper focus on female empowerment and the art of disguise.
