Netflix today dropped first look photos and a teaser for a new adaptation of Agatha Christie’s Seven Dials, the three-part series written by Chris Chibnall (Broadchurch, Doctor Who). Premiering on Netflix January 15, 2026, the series stars Mia McKenna-Bruce (How to Have Sex, Persuasion) as young sleuth Lady Eileen “Bundle” Brent.
Per Tudum, the synopsis reads, “England. 1925. At a lavish country house party, a practical joke appears to have gone horribly, murderously wrong. It will be up to the unlikeliest of sleuths — the fizzingly inquisitive Lady Eileen “Bundle” Brent (Bruce) — to unravel a chilling plot that will change her life, cracking wide open the country house mystery. A witty, epic, and fast-paced drama from the Queen of Crime, Agatha Christie, is brought to life in a thrilling new version for Netflix.”
Agatha Christie’s Seven Dials also stars Helena Bonham Carter (The Crown, One Life), Martin Freeman (The Responder, Sherlock), Corey Mylchreest (Hostage, Queen Charlotte), Ed Bluemel (Belgravia: The Next Chapter, Killing Eve), and Nabhaan Rizwan (Film Club, Dope Girls).
Chibnall executive produced the series via his company Imaginary Friends. It is also executive produced by Suzanne Mackie (Behind Her Eyes, The Crown), Chris Sussman (Fleabag, Good Omens), and Chris Sweeney (The Tourist, Back to Life), who also directed all three episodes.
