For fans of period dramas seeking an engaging binge this weekend, Netflix’s miniseries The Seven Dials Mystery is an excellent choice.
Released in 2026, the series adapts Agatha Christie’s 1929 novel, bringing to life one of her lesser-known amateur sleuths, Lady Eileen “Bundle” Brent.

The cast is star-studded, featuring familiar faces such as Martin Freeman (Sherlock), Helena Bonham Carter (The Crown), Edward Bluemel (Sex Education), and Iain Glen (Game of Thrones). Supporting roles include talents like Nyasha Hatendi (Alex Rider), Alex Macqueen (The Inbetweeners), Nabhaan Rizwan (Film Club), Corey Mylchreest (Queen Charlotte: A Bridgerton Story), Mark Lewis Jones (Keeping Faith), and Ella Bruccoleri (The Other Bennet Sister).

The three-part narrative delivers a jaw-dropping twist in its finale, leaving fans hopeful for a potential sequel.
Filming took place across beautiful locations including Lincolnshire, Bath, Bristol, and the scenic West Somerset Railway. Notably, the grand home of Bundle and Lady Caterham—known as Chimneys—was filmed at the historic Grade II listed Badminton House in Gloucestershire, an estate celebrated for its sprawling gardens and Roman villa ruins. The West Somerset Railway’s seaside stops at Blue Anchor and Minehead provided breathtaking coastal visuals.
Critics and viewers alike have lauded the series for its production quality and atmospheric charm. On IMDb, one user praised it as “A charming, languid murder mystery where Downton Abbey meets Agatha Christie!” Another commented, “Loved! Upgraded Agatha Christie with a Traitors vibe!” The costumes, soundtrack, and performances garnered strong appreciation, with particular acclaim for McKenna-Bruce’s standout portrayal of Bundle.
Reddit fans also expressed enthusiasm, with one remarking, “I thought the last episode was splendid!!! I love train scenes.”
The Seven Dials Mystery is now streaming on Netflix and promises a quintessentially British, visually stunning murder mystery perfect for period drama aficionados.
