In Agatha Christie’s Seven Dials, the clock is ticking for Lady Eileen “Bundle” Brent (Mia McKenna-Bruce) as she sets out to solve a murder case in this reimagined version of Christie’s timeless mystery. “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,” McKenna-Bruce tells Tudum. “I really feel like we did what we set out to do.”

This modern take on the Seven Dials story begins in the 1920s at a glamorous party where the handsome Gerry Wade (Corey Mylchreest) hints at his intentions to propose to Bundle. The next morning, however, she’s shocked to discover her future fiancé still in bed, even as seven alarm clocks cacophonously sound inside his room. It turns out, Gerry isn’t sleeping — he’s dead, and a devastated Bundle is now determined to work out who is responsible for his untimely end. “I’m not going to rest until I find out what happened to him,” she tells her mother, Lady Caterham (Helena Bonham Carter), in the trailer above. 

“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,” says McKenna-Bruce. “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.”

Following a hunch that the seven clocks and something called “the Seven Dials” are somehow connected to Gerry’s death, Bundle begins to investigate with some assistance and warnings from her friends Ronnie Devereux (Nabhaan Rizwan) and Jimmy Thesiger (Edward Bluemel). Soon, she meets Battle (Martin Freeman), a Scotland Yard superintendent who’s looking into the case, and poses the question: “What do you know about Seven Dials?” With a glint of recognition and perhaps awe, Battle advises the young lady that she’d be better off leaving this work to the professionals. “This is treacherous with a high degree of peril,” he says as the trailer continues to unfold. 

But just as McKenna-Bruce explains of her spunky character, Bundle isn’t one to let things go. “I am not going to stop until I get to the truth,” she proclaims — even if that means taking a few tumbles and sticking her nose where some might think it doesn’t belong.
