Barrister turned novelist Harriet Tyce is playing a blinder in the fourth series of the show. As a thriller writer myself, I recognise the traits that make her such a formidable Faithful

This time last year a rumour swept through the close-knit British crime-writing community, not whispered in a quiet moment in the billiard room but shared on group chats and message boards. The producers of The Traitors were recruiting contestants for 2026, and wanted one of us to take part. Of course they did! The Traitors is a controlled, lower-stakes, stylised version of the golden age country house whodunnit, which is itself a controlled, lower-stakes, stylised version of real-life murder. It is crime writers’ job to examine the dark side of human behaviour. Betrayal of trust and manipulation are all in a day’s work. We often write from multiple perspectives, identifying with victim, perp and detective, giving us a unique kind of empathy. We spent the rest of the year wondering who it would be. (I didn’t get the call.)

Last November, in that howling no man’s land between the finale of Celebrity Traitors and the transmission of series four, I went along with 13 fellow crime novelists to the Traitors Live Experience in Covent Garden. Despite being professional pattern-finders with highly tuned powers of observation, none of us at the replica round table guessed that the Chosen One was among us, and had already completed her stint on the real thing.
