Agatha Christie is one of the biggest names in the world of fiction, and her popularity has only increased with the passage of time. Her mysteries are usually built around ideas that never really go out of fashion, genuinely inviting readers to find the missing pieces together alongside the characters. Over the years, Christie's novels have given us several iconic characters, including Miss Marple and Hercule Poirot. Most of her leading characters are individuals trying to solve crimes. However, the author also explored crime-solving as a partnership through Tommy & Tuppence, two amateur detectives trying to solve crimes while dealing with their problems.

If you are not familiar with Christie's work, you might not even know about their partnership. To make things simpler, BritBox is bringing the duo to the small screen in their upcoming series, titled Tommy & Tuppence. The show chronicles the journey of Tuppence Cowley (played by Josh Dylan) and Tommy Beresford (played by Antonia Thomas) as they try to navigate dangerous crimes, complicated relationships, and their own different approaches to solving a mystery. NetflixJunkie caught up with Dylan and Thomas to discuss various aspects of the series. 

The conversation also explores how Christie's themes of deception and hidden identities still resonate today. That is what makes this series such a compelling watch, while for Dylan and Thomas, that tension between appearance and reality is what makes Tommy and Tuppence's partnership even more compelling.

Aayush Sharma: Agatha Christie is often celebrated for her mysteries, but Tommy & Tuppence arguably represent one of her most nuanced explorations of partnership. What did this series reveal to you about the difference between solving a crime together and truly knowing another person?

Josh Dylan: Well, I suppose you get to know a person very, very well by trying to solve a crime. There’s nothing more important than life and death.

Antonia Thomas: They find themselves in really dangerous and sticky situations, and I suppose the way they get into those situations is very much down to their personalities. Tuppence will barrel ahead, you know, going head-on into a situation without even thinking twice, while Tommy is always there trying to put the brakes on that and be a bit more considered. So they get to know each other really well. They already knew each other in our version of the story. They had known each other 10 years ago and had been in a relationship, and those personality differences were perhaps what caused them to break up in the first place. But now they're rediscovering one another through these crimes. They have a great appreciation for each other, but they still manage to frustrate each other too.

Aayush: One of the fascinating aspects of Tommy and Tuppence is that they are not isolated geniuses like Poirot or Miss Marple; they succeed through collaboration. How did that dynamic influence your performances, and what does it say about the value of partnership in today's world?

Josh: You have a character like Poirot, for example, and the magic of a character like that is that you feel they kind of know everything before it happens. There is almost a sixth sense to it. Tommy and Tuppence don’t have that.

Antonia: They do not know what they are doing. They are amateurs.

Josh: They don’t know what they are doing. They are amateurs who are just tumbling into these situations, and they need each other. They would not be able to do it alone. So it is very much a partnership, and it is chaotic and haphazard, but also charming and kind of perfect because of that. They just bounce off each other, but they have not figured everything out. I think that was something we really tried to be honest about, and we really enjoyed that. Hopefully, that is what makes it feel relatable, because people love true crime. They love the idea that anyone can solve a crime, that anyone can try to put the pieces of the puzzle together. With Tommy and Tuppence, you really feel like they are figuring it out as they go. They do not know what’s going to happen, and I think that makes it feel quite alive.

Aayush: Agatha Christie's stories frequently examine how people construct versions of themselves for the world to see. In an era of social media and carefully curated identities, did that theme feel especially relevant while portraying these characters?

Antonia: These characters definitely have the version of themselves that they want the other person to see, and then there is the version of themselves that they’re still trying to figure out. Tuppence, for example, has been living in L.A. and is trying to be an actress. When she bumps into Tommy in London, she wants him to think that she is successful, that she is doing well, and that all of her choices have worked out perfectly. But that’s actually very different from where she is in her life.

Tommy, meanwhile, is a successful crime writer, but he’s also dealing with writer’s block and does not know how to finish his book. So when they first meet again, they’re both putting on this front. They are not really being honest about where they are in their lives, and that goes even deeper because they’re definitely not honest with each other about how they feel. They are both, in a way, the one that got away for the other. So that idea of the version of yourself that you present to someone versus the version of yourself that’s actually real is a huge element of their relationship.

Josh: That’s also a theme with the other characters they come across along the way. You’ve got Archie St. Vincent, I think, in the third or fourth episode, and all these people who present themselves in one way, and then you slowly learn that there’s something else going on. It’s all about appearance versus reality. That’s such a classic Agatha Christie thing because it makes you feel like a murderer could be hiding in plain sight. You have to question everyone and always be on your guard.

Tommy & Tuppence will be streaming exclusively on BritBox on September 15th.
