Tom's Guide verdict

"Agatha Christie’s Seven Dials" is a witty, high-speed romp that nails the binge-watch formula, powered by a sharp ensemble and a breakout lead performance from Mia McKenna-Bruce.

Netflix has kicked off 2026 with several buzzy mystery shows, but I think the streamer's latest release just might be my favorite of the bunch, so far. So yes, while you could be catching up on "Run Away" or streaming "His & Hers," I'd personally recommend carving out an evening to stream "Agatha Christie's Seven Dials" instead.

To be crystal clear, while I've read some of Christie's works, I'm not familiar with the original story, so I can't judge how faithful it is. That said, having watched the series in advance of its arrival, I can say that I thoroughly enjoyed following this particular romp through to its end — read on to find out why.

Watch On

Chris Chibnall's new Netflix miniseries takes us back in time to England in 1925. At a lavish country estate party, a practical joke appears to have gone murderously wrong.

Suspecting foul play's afoot, Lady Eileen "Bundle" Brent (Mia McKenna-Bruce) sets out to unravel what actually happened, and in trying to crack this particular mystery wide open, she uncovers a chilling plot that will change her life forever.

In addition to McKenna-Bruce, "Agatha Christie's Seven Dials" also features Helena Bonham Carter, Martin Freeman, Corey Mylchreest, Ed Bluemel, Nabhaan Rizwan, and Alex Macqueen.

'Agatha Christie's Seven Dials' is a delightful murder-mystery miniseries

Over on Tudum, Netflix bills their latest original series as "a witty, epic, and fast-paced drama," and, frankly, I can't think of a better way to succinctly sum up "Agatha Christie's Seven Dials" myself. Netflix is home to a number of these kinds of distinctly British-coded affairs, but I can't recall one that I've enjoyed more in recent memory.

Tonally, prospective viewers can expect "Seven Dials" to be a spirited, playful and cheeky drama. There's murder, of course, but this is a charming miniseries that throws us into the mystery and then never really lets up.

I've purposefully avoided spoilers wherever I can, because it's best experienced blind, but once the clues start being discovered and the shocks start to pile up, we're soon being treated to a twisting, dramatic watch that contains all manner of secrets, and several thrills to match.

It helps that Chibnall and co. have assembled a strong ensemble, and they bring their respective characters to life with verve (with Freeman's Superintendent Battle being a particular personal highlight). Of course, the series wouldn't work without a capable actor steering proceedings, and Mia McKenna-Bruce shines as Lady Eileen, our inquisitive amateur investigator.

All in all, "Agatha Christie's Seven Dials" is a compelling, characterful, and perfectly paced Netflix binge. Initially, I thought running for just three episodes — each under an hour long — was an odd choice, but I think it might be the perfect amount for this show; it left me wanting more, but perfectly satisfied with the mystery at hand.

Simply put, if you love watching a detective go to work and you're in the market for a charming, propulsive series, I'm confident you'll have a blast if you choose to stream "Agatha Christie's Seven Dials" on Netflix.
