In 1925 England, a playful joke at a grand country house party takes a deadly turn. Lady Eileen ‘Bundle’ Brent, an unusually curious woman, must solve the mystery and uncover a sinister plot that will forever alter her life. This thrilling new adaptation on Netflix brings Agatha Christie’s witty, sweeping, and fast-paced story to life.
Joining McKenna-Bruce are India Amarteifio (known for Queen Charlotte) as Gerry Wade, Sophie Okonedo as Battle, Helena Bonham Carter as Lady Caterham, Niamh Algar as Ronnie Devereux, and Samuel Blenkin as Jimmy Thesiger.
The latest pictures hint at the strange happenings and show how determined Bundle is to solve the mystery.


Suzanne Mackie from Orchid Pictures, a key production team on the show, stated that working with Chris Chibnall, the writer and executive producer, on this creative and ambitious series has been a wonderful experience.
We’re incredibly excited to be starting this project with Chris Sussman, Agatha Christie Limited, and the talented director Chris Sweeney. This feels like the perfect first venture for Orchid Pictures, and we couldn’t imagine a better place for this story than Netflix, according to Tudum.
Chris Chibnall, the creator of Broadchurch, teamed up with James Prichard, Agatha Christie’s great-grandson, who executive produced the project through Agatha Christie Limited. Mackie, known for his work on The Crown, also served as an executive producer.

Prichard told Tudum that Bundle Brent, a character from Agatha Christie’s Seven Dials, is one of his great-grandmother’s many witty, clever, and engaging young female characters.
As a huge fan, I’m absolutely thrilled to see this character finally come to life! It’s a dream come true to see Chris Chibnall’s writing and this amazing production from Orchid Pictures and Netflix bring her story to the screen. I really think audiences are going to fall in love with the world we’ve built, and I’m already hoping we get to explore it even further!
Agatha Christie’s Seven Dials will premiere on Netflix on Thursday 15 January 2026.
