There's something gloriously perverse about taking Agatha Christie's beloved detective duo, dragging them into the 21st century, and telling them to solve murders while navigating the emotional wreckage of a busted romance. It's like taking a vintage jukebox, plugging it into a nightclub sound system, and hoping the damn thing doesn't blow a fuse. Sometimes it does. Sometimes it delivers a hell of a party. BritBox's Agatha Christie's Tommy & Tuppence, a six-part mystery series starring Antonia Thomas and Josh Dylan, manages to do a little of both.
This isn't your grandmother's Christie. Actually, that's precisely the point.
Tommy Beresford (Dylan) is a meticulous crime novelist whose creative engine has stalled somewhere between writer's block and existential despair. Tuppence Cowley (Thomas) is a struggling actress with a gift for improvisation, a restless spirit, and a knack for barging into situations that sensible people would avoid. Former lovers who have somehow managed to remain emotionally entangled, the pair reunite at a lavish wedding where a murder promptly turns the festivities into a crime scene. When an old friend becomes the prime suspect, they plunge into amateur sleuthing, assisted by Tommy's formidable Aunt Ada (Imelda Staunton), a retired private investigator with a taste for cutting observations and a healthy disregard for conventional wisdom.
The setup is a deliciously old-fashioned cocktail served in a thoroughly modern glass. Writer Phoebe Eclair-Powell has relocated Christie's characters to contemporary London, where social media, smartphones, and modern attitudes collide with the familiar pleasures of suspicious strangers, buried secrets, and suspiciously convenient alibis. The result is a show that wants to have its vintage cake and eat it, too.
But let's be honest: The murders aren't the main attraction. The chemistry between Thomas and Dylan is.
Thomas plays Tuppence like a live wire plugged directly into the national grid. She's impulsive, mischievous, and perpetually on the verge of turning a perfectly ordinary conversation into an undercover operation. Dylan's Tommy is her wonderfully exasperated counterweight, a man whose meticulous habits and earnest decency are constantly being steamrolled by the woman who knows precisely which buttons to push. Together, they generate the sort of combustible romantic tension that makes you want to yell at the television, "For God's sake, just kiss already!"
Their banter crackles with the energy of two people who know each other's weaknesses far too well. A glance becomes a challenge; a sarcastic remark becomes an invitation. There's genuine affection beneath the bickering, and the actors understand that the best romantic comedy often comes from the things characters refuse to say. Thomas brings a deliciously theatrical flair to Tuppence's disguises and improvisations, while Dylan's understated charm makes Tommy's occasional flashes of frustration all the more amusing.
Unfortunately, the mysteries themselves don't always keep pace. The clues are often more decorative than challenging, the suspects occasionally feel like cardboard cutouts wearing expensive costumes, and the resolutions lack the diabolical ingenuity that made Christie the undisputed queen of the whodunit. The series wants to be a puzzle box, but sometimes it feels more like a gift box containing a few predictable surprises.
And then there's the nostalgia problem. Christie has become a cultural institution, and adapting her work means navigating the minefield between reverence and reinvention. This version makes a deliberate break with the past, embracing contemporary casting, modern relationships, and a more inclusive London. That's a perfectly legitimate creative choice. But updating the furniture doesn't automatically make the house more interesting. At times, the series seems so eager to announce its modernity that it forgets to make its mysteries genuinely surprising.
Still, there's a lot to enjoy here. Staunton is a terrific presence as Aunt Ada, dispensing wisdom and mischief with the authority of someone who has seen every conceivable human foolishness and found most of it entertaining. The supporting cast adds texture, and the show's cozy atmosphere makes it an appealing antidote to the grim, blood-soaked crime dramas that have turned murder into a competitive sport.
The bottom line? Agatha Christie's Tommy & Tuppence is a charming, occasionally exasperating romantic mystery that succeeds more as a flirtation than as a brainteaser. Its greatest mystery isn't who committed the murder, but how two people so obviously crazy about each other can spend so much time pretending otherwise.
Thomas and Dylan provide the spark. Christie provides the blueprint. And the rest is a pleasant, if sometimes predictable, dance around the body.
It's not the second coming of the great detective drama. But as a cozy little crime caper with a couple of irresistible leads, it knows how to have a good time.
