Agatha Christie’s Seven Dials Trailer: Netflix Assembles Starry Cast For New Murder-Mystery Series
Spooky season may be over for another year, but you can always rely on a good old-fashioned murder-mystery to keep the chills running right through winter — and this year’s no different. Today, Netflix has unveiled the first trailer for Broadchurch creator Chris Chibnall’s latest whodunit, a star-studded adaptation of Agatha Christie’s classic novel The Seven Dials Mystery. Aptly titled, well, Agatha Christie’s Seven Dials, the three-part limited series is set to see Helena Bonham-Carter, Martin Freeman, Nathan Rizwan, and more caught up in a country house prank gone lethally awry, with How To Have Sex breakout Mia McKenna-Bruce getting her sleuth on to solve the grisly case. Check out the tantalising teaser below;
Big ol’ stately home? Check! Dead bodies on the forecourt? Check! A bunch of shifty, secretive folks acting shifty and secretive? Check! You wouldn’t have to be Sherlock Holmes — or, er, Miss Marple — to figure out that Agatha Christie’s Seven Dials has all the deliciously dark trappings of a classic take on a Queen of Crime deep-cut. And, what’s more, with this one we’ve even got a new sleuth to play armchair detective alongside in the form of McKenna-Bruce, getting her 1920s chic on as the tenacious Lady Eileen “Bundle” Brent. Sure, this may be only around a minute’s worth of a glimpse at what Seven Dials has in store, but it’s already looking like a killer (sorry). And hey, there’s even a Watson in the house — hello to Sherlock‘s finest Mr. Martin Freeman!
Here’s the official synopsis to pore over: “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.”
Between Rian Johnson’s speedily approaching Knives Out threequel Wake Up Dead Man, the recent announcement of a sixth season of Only Murders In The Building just confirmed at Disney+, and now this, the murder mysterenaissance (as only we are still calling it) continues apace. We’ll catch you in the billiards room with a crackpot theory as to who did it when Agatha Christie’s Seven Dials hits Netflix on 15 January, 2026.
