The world of crime writing and the treacherous game of BBC's The Traitors share more DNA than you might think. As the show's fourth series captivates the nation, barrister-turned-novelist Harriet Tyce is demonstrating precisely why those who craft fictional mysteries make such formidable players.
The Perfect Recruitment: A Crime Writer in the Castle
Last year, a tantalising rumour circulated through the UK's crime-writing community. Producers for The Traitors were recruiting for 2026 and specifically wanted a crime author to take part. For Erin Kelly, a bestselling thriller writer herself, the logic was impeccable. The show is a stylised, modern take on the classic country house whodunnit, a genre built on betrayal, manipulation, and uncovering hidden truths.
"It is crime writers’ job to examine the dark side of human behaviour," Kelly notes. "Betrayal of trust and manipulation are all in a day’s work." This professional insight into motive and deception, coupled with the ability to write from multiple perspectives, gives authors a unique form of empathy—a crucial skill in the game.
Courtroom Panache and the Art of Misdirection
Harriet Tyce's background as a barrister has been her secret weapon. Her masterful unmasking of Traitor Hugo in episode three was a clinic in persuasive argument. Her speech was eloquent, controlled, and incisive—pure courtroom drama translated to the round table.
"You have experience at cross-examination, you’re good at presenting your case and you’re highly articulate," she told Hugo, presenting her theory as unassailable fact. In an environment where "hard facts" are scarce, Tyce's ability to deliver "near-truths with panache" is a powerful tool. As Kelly observes, this is the essence of a crime writer's craft: misdirecting the reader so skilfully they never think to question it.
Soft Skills and the Dark Side
But is it all about legal training? Fellow author Mark Edwards, a self-confessed Traitors superfan, points to other useful authorial traits. "To be a successful author you have to be comfortable talking to people and making them like you," he says, highlighting the networking skills vital for a Faithful's survival.
And what of the potential to be a Traitor? Edwards believes crime writers are uniquely equipped for the role. "To make twists work, we have to be able to create characters who are good at lying and pretending to be good guys. These baddies are always the most fun characters to write, and I think we would all relish the chance to be one of them."
The ultimate advantage for a crime writer-Traitor, however, might be the love of dramatic irony—the joy of knowing something the characters (or in this case, the Faithfuls) do not. As Erin Kelly concludes, that, coupled with a mischievous streak, is the very essence of Traitorhood.
Harriet Tyce continues to play a blinder in Series 4, proving that the skills honed crafting plots in a fleece covered in pet hair can translate spectacularly well to the high-stakes drama of Ardross Castle.
