Mystery lovers and Netflix detectives, assemble. Agatha Christie’s Seven Dials arrives on screens on January 15, 2026, with a promise of intrigue, glamour, and so much sleuthing that your heart will do a little jitterbug. You do not need Hercule Poirot’s moustache to enjoy this one, but by the end, you might be doing your own detective impressions. This series brings to life one of Christie’s lesser-adapted novels, The Seven Dials Mystery, originally published in 1929. The story has charm, wit, danger, and an aristocratic lady who refuses to just sip tea when there’s a puzzle to solve.
Agatha Christie’s Seven Dials: Release Date and Format
Netflix will stream this new mystery series starting January 15, 2026. It will be a three-episode limited event, so it does not drag its feet like that one friend who never replies to texts. Everything is packed into these episodes with purpose.
The series stars a mix of brilliant performers who bring Christie’s characters to sparkling life. Mia McKenna-Bruce plays Lady Eileen “Bundle” Brent. Bundle is smart, brave, and curious. She does not sit quietly while a mystery unfolds, and she definitely does not trust the first obvious explanation. Helena Bonham Carter is Lady Caterham, a character who likely has secrets tucked into her elegant gloves.
Martin Freeman plays Superintendent Battle. If you have seen him before, you know he brings charm with grounded seriousness. Other cast members include Edward Bluemel, Corey Mylchreest, Nabhaan Rizwan, and Alex Macqueen in key supporting roles. Each adds to the world of twists, distractions, and tension.
What the Story Is About
We meet our mystery in 1925 England at a grand country house party full of laughter, music, and yes, questionable decisions. A practical joke involving a cluster of alarm clocks goes very wrong, and a guest is found dead before breakfast. Cue ominous music.
Bundle Brent refuses to believe this is a simple accident, or even a bored butler situation. She dives headfirst into a web of secrets, hidden alliances, and a dangerous plot that is more twisted than your headphone cables after a workout.
Agatha Christie’s Seven Dials: Behind the Scenes and Production
The series was filmed mostly in the United Kingdom, in beautiful historic locations such as Bristol and Bath, with some scenes shot in Spain to bring richness and variety to the visual palette. The show was adapted by Chris Chibnall, best known for his work on Broadchurch, and directed by Chris Sweeney. That creative team gives this classic a modern rhythm while staying true to Christie’s classic storytelling.
This is not a dusty old mystery you need to read a glossary for. It is sharp, stylish, and loaded with character energy that even your group chat would envy. Christie fans will find familiar clever twists, and new viewers will get one of the best ticketed entries into classic mystery fiction. So mark your calendars. Grab your snack stash. And start practicing your best “I knew it all along” wave for January 15, because Seven Dials is coming.
