The Traitors’ Harriet Tyce says her experience could inspire a new book "in time"

The Traitors season 4 pulled out all the stops, from new twists in the form of a secret Traitor to allowing the Faithful to ask the Traitors questions, hoping to unearth their identities.

The latter twist involved Harriet Tyce, who was absolutely sure that Rachel Duffy was a Faithful, though due to a lack of evidence beyond a gut feeling, her fellow players weren't convinced.

Despite revealing herself to be a Faithful after being banished, Harriet had been keeping a handful of secrets from her fellow players....

Not only did she hide that she was a former barrister, but also that she was a successful crime writer, who has published four gripping crime novels, with a fifth to be released next month.

But could another story be on the way, perhaps inspired by her turn in The Traitors castle?

The question was posed to Harriet at the Radio Times Covers Party 2026, and there is hope yet!

"Maybe in time. The psychology of all of it fascinates me. I mean, I can't tell you how much the immersive experience, how different people react to that," Harriet told RadioTimes.com. "Whether you believe it [or] you don't believe it, it's real and I think that there's something in that.

"But in terms of some sort of roundtable, picking them off one by one? No, that that won't be happening. But I think in a while maybe."

Harriet certainly has her hands full with the release of her new book, Witch Trial, on Thursday 26th February.

The synopsis for the story reads: "When 18-year-old Christian Shaw is found dead in an Edinburgh park, the city reels - and the shock only deepens when police charge her best friends, Eliza Lawson and Isobel Smyth, with her murder.

"As social media explodes and headlines scream for justice, rumours of bullying spiral into something darker: whispers of rituals, obsession, and a teenage pact gone wrong."

It continues: "Matthew Phillips, a respected heart surgeon, is reluctantly called for jury duty on the case. But as the trial unfolds - and the girls reveal a chilling defence no one saw coming - he begins to question everything: the motives, the evidence, even his own judgement.

"Who's telling the truth? Who can be trusted? And what really happened to Christian Shaw? Let the Witch Trial begin..."
