Netflix trailer unveils new take on Torquay-born Agatha Christie’s The Seven Dials Mystery

Netflix has released the first trailer for Agatha Christie’s Seven Dials, a gripping new series based on the Queen of Crime’s 1929 novel The Seven Dials Mystery, and it has special significance for Torquay, where Christie herself was born and raised.

The three-part drama, which lands on the streaming platform on 15 January 2026, transports viewers back to 1920s England, where a light-hearted country house prank turns into a chilling murder investigation.

The story follows the inquisitive and unconventional Lady Eileen “Bundle” Brent, played by Mia McKenna-Bruce (How to Have Sex), as she unravels a sinister plot that will change her life forever.

The series has been adapted by Chris Chibnall, the creator of Broadchurch, and directed by Chris Sweeney.

Originally published in 1929, The Seven Dials Mystery was one of Christie’s first forays into espionage fiction, a genre she explored alongside her classic whodunnits.

The first UK edition was priced at seven shillings and sixpence, and like much of her work, it captured the social world and eccentricities of interwar England.

For Torquay readers, the story holds an added layer of pride and nostalgia.

Agatha Christie was born in Torquay on 15 September 1890, at a Victorian villa named Ashfield on Barton Road.

Growing up on the English Riviera, Christie drew inspiration from the area’s grand hotels, sea views and genteel social scene, elements that would later feature in her novels.

Torquay today proudly celebrates its most famous daughter.

The Agatha Christie Mile guides visitors along key locations connected to her life, from Princess Pier, where she learned to roller-skate, to The Imperial Hotel, which inspired settings in both Peril at End House and Sleeping Murder.

Torquay Museum also houses the UK’s only permanent Agatha Christie Gallery, displaying personal items, photographs and first editions.

Christie went on to become the world’s best-selling novelist, with more than two billion copies of her books sold worldwide.

Her most famous creations, detectives Hercule Poirot and Miss Marple, have become cultural icons, and adaptations of her work continue to find new audiences nearly half a century after her death in 1976.

With Agatha Christie’s Seven Dials, Netflix brings one of her early mysteries to a global audience, while rekindling interest in her roots on the South Devon coast.
