Netflix’s latest Agatha Christie adaptation, Agatha Christie’s Seven Dials, premiered globally on January 15, 2026, as a gripping three-part limited series. Created and written by Chris Chibnall—the acclaimed mind behind Broadchurch and Doctor Who—this fresh take on Christie’s 1929 novel The Seven Dials Mystery promises slow-burn suspense, sharp character work, and atmospheric intrigue rather than cozy nostalgia.

Set in 1925 England, the story unfolds at a lavish country house party at The Chimneys, where a seemingly harmless practical joke involving alarm clocks goes horribly wrong. Guest Gerry Wade (Corey Mylchreest) is found dead under suspicious circumstances, turning mischief into murder. The investigation falls to the spirited Lady Eileen “Bundle” Brent (Mia McKenna-Bruce), a witty, determined young aristocrat who refuses to let the authorities handle it alone. As Bundle digs deeper, she uncovers a darker conspiracy involving secret societies, espionage, stolen inventions, and wartime loyalties—elements that expand the original novel’s scope into a more epic, fast-paced thriller.

Mia McKenna-Bruce, fresh off her BAFTA Rising Star win for How to Have Sex, leads as Bundle, bringing fizz and pluck to the role. She described it as a “dream” part, praising Chibnall’s “brilliant” scripts for making Christie accessible while staying true to the heart of her mysteries. Helena Bonham Carter excels as Bundle’s aloof mother, Lady Caterham, capturing faded gentry elegance with her signature eccentricity. Martin Freeman plays the no-nonsense Superintendent Battle—a recurring Christie detective known from earlier novels—delivering grounded authority and subtle humor. The ensemble includes Edward Bluemel as Jimmy Thesiger, Nabhaan Rizwan as Ronnie Devereux, Iain Glen, and others, adding layers of suspicion and red herrings.

Chibnall’s involvement raises expectations high. Known for character-driven, emotionally resonant mysteries like Broadchurch, he reimagines this lesser-adapted Christie tale (previously a 1981 TV film) with bold ambition. Filmed in 2024 in Bristol, Bath (using Badminton House for The Chimneys), and Ronda, Spain, the series boasts lush 1920s period detail—opulent manors, flapper fashion, and tense drawing-room confrontations—while leaning into intrigue over light-hearted thrills. Early reviews praise McKenna-Bruce’s breakout performance and the cast’s chemistry, though some note pacing issues or tonal inconsistencies in the mystery’s complexity.

As Netflix’s first Christie project under Orchid Pictures (debut banner from The Crown exec Suzanne Mackie), Seven Dials aims to introduce iconic characters like Bundle to new audiences. James Prichard (Christie’s great-grandson) executive produces via Agatha Christie Limited, ensuring fidelity to the source. With all three episodes (53–56 minutes each) dropping at once, it’s binge-ready for fans craving classic whodunits with modern edge.

Whether you’re a die-hard Christie reader or new to her world, this adaptation delivers suspense, sharp dialogue, and a plucky heroine worth rooting for. Stream it now on Netflix— the clocks are ticking.
