WARNING: spoilers for The Traitors UK season 4 ahead.

If you saw the advert for The Traitors UK season 4 over Christmas and were convinced the red Traitors cloak meant something, you were right. On top of our typical traitors turret, there's now a Secret Traitor that nobody knows about... including us.

Here's how it works. As it stands, nobody but presenter Claudia Winkleman and the production team knows who the Secret Traitor is, but they know everyone's real roles in the game. So our classic green-cloak traitors – Rachel, Hugo and Stephen – know that a fourth traitor is amongst them, but they've got no idea who.

As Winkleman herself says in the premiere, "The Secret Traitor will work alone. Each night they will provide you with a murder shortlist. You can only murder one of the people that is on the murder shortlist. You do not know who they are – but they know exactly who you are.”

This completely changes the role of our known traitors in the game. They're no longer able to freely choose who to murder, which in turn makes them a lot more vulnerable. They're not exactly thrilled about the shocking new twist, either.

For the armchair detectives among us, this is brilliant news. For the first time, we're now playing along with the Faithful, trying to work out who is under the red cloak. Thankfully, there's a clue right under our noses.

The murder shortlist cannot contain the traitors we know about, but they also can't contain the Secret Traitor either. By process of elimination, we should be able to narrow down who it could be by ruling out anybody who appears on the shortlist.
