Leading suspects include psychologist Ellie, local government officer Fiona, recruiter Roxy, and PhD student Jade, with viewers citing clues such as handwriting, behaviour, and alleged pre-show connections.
Crime novelist and former barrister Harriet Tyce is considered the top suspect, following a reported production blunder on the companion show Traitors: Uncloaked that seemingly revealed her photo as a traitor.
Further evidence against Harriet includes her handwriting similarities to the secret traitor's and her strategic role in convincing the group to banish another traitor, Hugo, to gain trust.
