When old flames bump into each other at a themed wedding, a chance reunion quickly becomes a tangled detective story. BritBox’s new series reimagines Agatha Christie’s lesser-known sleuths, Tommy and Tuppence, in contemporary London. The show mixes romance, amateur sleuthing, and dark secrets as two former lovers are pulled into crimes that refuse to stay buried.
A fresh Agatha Christie take set in today’s London
This adaptation relocates Christie’s detectives to modern streets and coffee shops. Josh Dylan plays Tommy, a crime writer who takes a favor that pulls him back into a world he thought he’d left behind. Antonia Thomas is Tuppence, an aspiring actress recently returned from Los Angeles. Their reunion sparks more than nostalgia. It ignites a mystery.

BritBox positions this as the first modern English-language screen version of Tommy and Tuppence. The series leans into urban textures and contemporary concerns while keeping Christie’s puzzle spirit intact.
How the plot gets rolling: a wedding, a body, and an arrest
The opening episode stages an Alice in Wonderland–styled wedding. Tuppence is working the event. Tommy is on hand to take photos. Their encounter is brief but electric. That night, a guest is discovered dead. The groom is arrested. The case pushes the protagonists to work together again.
- Unusual setting: a themed nuptial that quickly turns macabre.
- Immediate stakes: a murder, a detained suspect, and confused witnesses.
- Personal complications: Tuppence’s unsettled life and Tommy’s tangled past.
Pacing issues and when the story finds its stride
The first two episodes feel reluctant to hurry. Clues arrive unevenly, and the plot hops between relationship beats and investigative threads. At times, personal drama eclipses the mystery. The initial case spills into the second episode and strains momentum.
Still, there is a turning point. Late in Episode 2, Aunt Ada—a retired private investigator and family anchor—drops a detail that resets the direction of the series. Her intervention helps the pair move from amateurs reacting to events to sleuths taking initiative.
Characters that grow on you: chemistry, conflict, and a guiding voice
Imelda Staunton plays Aunt Ada, the show’s wise observer. Her narration and counsel shape the narrative. As Tommy and Tuppence warm to their roles, the actors’ interplay strengthens.
The series highlights their contrast: Tommy is cautious and methodical. Tuppence is impulsive and daring. That tension fuels both drama and humor.
- Tommy (Josh Dylan): careful, literary, inclined to doubt.
- Tuppence (Antonia Thomas): bold, restless, hungry for purpose.
- Aunt Ada (Imelda Staunton): experienced, dryly funny, the moral compass.
Episode 3 and the mysteries that deepen
By Episode 3, the storytelling tightens. A case about a stolen pearl necklace morphs into a darker revelation. The plot twist in this episode rescues the earlier clunkiness and reveals more complex motives.
Local police become major players. Detective Sergeant Draper offers cautious cooperation. Detective Inspector Merriot pushes back. The pair’s involvement creates fresh friction and raises the stakes for the amateur agency they form: Blunt’s Brilliant Detectives.
What the final episodes deliver: time jumps and higher stakes
The season’s second half escalates. The narrative spans decades, beginning with a Halloween night in 1989 and moving into the present. The pace quickens. Twists arrive more frequently. The mysteries grow layered, and the emotional stakes follow.
Tuppence wrestles with a literal and figurative flight from her past. At times the show lingers on the romantic tension between the leads. Those moments can feel repetitive, but they never completely overshadow the central investigations.
Reasons to watch: strengths and areas that need polish
- Strong points: inventive modern setting, rising chemistry between the leads, and richer mysteries in later episodes.
- Weak points: slow opening, occasional focus drift toward relationship arcs, and pacing that improves only after episode two.
- Fans of cozy mysteries and Christie-style puzzles will find elements to enjoy.
Cast, release details, and where to stream
Josh Dylan and Antonia Thomas headline the series. Imelda Staunton adds gravitas as Aunt Ada. The show is produced for BritBox and aims to balance classic detective tropes with contemporary storytelling.
The first two episodes premiered Sept. 15 on BritBox. New episodes arrive weekly on Tuesdays. Viewers looking for a modern Christie experience should expect a slow burn that pays off in the back half.
