The story begins at an elegant country house gathering, where a seemingly harmless prank takes a dark turn. When one of the guests is found dead the next morning, surrounded by seven alarm clocks, Bundle senses that the strange arrangement holds the key to the truth. Refusing to step aside, she decides to investigate the case on her own.

A modern heroine in a classic Christie world
Played by Mia McKenna-Bruce, Bundle is portrayed as sharp, curious, and determined, pushing against the limits placed on women of her time. Her investigation brings her into contact with Superintendent Battle, portrayed by Martin Freeman, who warns her about the dangers linked to the shadowy Seven Dials organisation.
The series also stars Helena Bonham Carter as Bundle’s mother, Lady Caterham, alongside Edward Bluemel and Nabhaan Rizwan as her close allies. While the setting remains firmly rooted in the 1920s, the tone of the trailer suggests a faster, more character-driven approach aimed at engaging new viewers.
Seven Dials release date
Agatha Christie’s Seven Dials will premiere on Netflix on January 15, 2026, with all three episodes.
