Netflix debuts gripping new trailer for Agatha Christie's Seven Dials that sees Mia McKenna-Bruce, Helena Bonham Carter and Martin Freeman embroiled in a dangerous murder mystery

Netflix has treated Agatha Christie fans by dropping a new thrilling trailer for its upcoming adaptation of her 1929 novel, The Seven Dials Mystery.

The gripping three-part series sees Mia McKenna-Bruce putting on her detective hat in the role of Lady Eileen 'Bundle' Brent, as she set out to solve an enigmatic murder.

She is joined in the exciting mystery by acting icon Helena Bonham Carter as her mother, Lady Caterham and Martin Freeman in the role of Superintendent Battle. 

The trailer begins at a masquerade ball in the mid-1920s, where the handsome Gerry Wade is seen flirting and dancing with Bundle, before being interrupted right as it seems he is about to propose. 

However, the next morning the household are disturbed by the noise of a cacophony of alarm clocks from Gerry's room, sparking the ire of Lady Caterham.

A shocked and devastated Bundle investigates only to find her future fiancé lying dead in his bed, with seven clocks arranged on his mantlepiece.

Channelling her grief and despair into vengeance, she vows to uncover who is responsible for Gerry's death, telling her mother: 'I’m not going to rest until I find out what happened to him'.

But as she begins to delve into the mystery of 'the Seven Dials', she received repeated warnings to stay away by her friends Ronnie Devereux and Jimmy Thesiger, as well as Battle, a Scotland Yard superintendent looking into the case.

Ronnie warns: 'Be careful who you speak to about this', as Battle echoes: 'This is treacherous with a high degree of peril.' 

But ignoring their warnings, Bundle is seen stubborn continuing her investigation to get 'the full picture' while Lady Caterham insists: 'People who go looking for trouble usually find it'.

And the trailer shows that trouble is indeed brewing, as scenes flash of someone being shot, a masked figure, Bundle weeping over a bloodied body and then falling from a window.

However, she proclaims she will keep going until she finds out who murdered Gerry, vowing: 'I am not going to stop until I get to the truth'.

The timeless mystery has been reimagined for a modern audience by Broadchurch creator Chris Chibnall and is directed and executive produced by Chris Sweeney.

Speaking about the ways they've adapted it, Mia told Tudum: 'It was really important to make Agatha Christie feel accessible to people who hadn’t read her work but also hold on to the heart of those murder mysteries. I really feel like we did what we set out to do.'

While she explained how her character, Bundle, also behaves differently to how  upper-class women were expected to in the 1920s.

'She’s a go-getter. If you tell Bundle no, she’s just going to find another way to do it, and I love that about her,' the actress gushed.

'Particularly as a woman in 1925, she has a lot stacked against her, and she doesn’t let it deter her at any point. She knows the mission, and she cracks on.'

Alongside Mia, Helena and Martin, the star-studded cast also stars Corey Mylchreest as Gerry Wade, Edward Bluemel as Jimmy Thesinger and Nabhaan Rizwan as Ronnie Devereux. 

The plot 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 - to unravel a chilling plot that will change her life, cracking wide open the country house mystery.'

All three episodes of Agatha Christie's Seven Dials are set to land on Netflix on Thursday, January 15.

It marks the latest adaptation of one of the Queen of Crime's novels for the small screen, following a slew of versions by the BBC, including Witness For The Prosecution, And Then There Were None and last year's Towards Zero.
