Big changes have been made to The Traitors and the stakes are higher than ever after series two final saw Harry steal the £95,000 from friend Mollie.
There are the secrets you don't see on camera on The Traitors. Plus, The Traitors line-up, which includes a priest and an ex-soldier, have brought secrets into the BBC show before they were even declared a Faithful or a Traitor.
From putting on fake accents to pretending to have different jobs, it's clear series three's contestants don't mind telling white lies. In the words of host Claudia Winkleman, "If you're playing a game of deception, why not start at the beginning?"
Keith -- who was murdered in episode two -- had a secret that he didn't have the chance to reveal or be rumbled by any of the cast.
He told The Traitors Uncloaked podcast and show: "My big secret was being a black belt in taekwondo. I'm a first degree black belt in taekwondo and I didn't want to tell anybody that just in case."
If he had been on the game longer, he's convinced he would have let it slip.
Ahead of the series, he said: "I'm 65 but I'm also a black belt in Taekwondo... I will be bringing my Taekwondo outfit when I head to Scotland."

Faithful Charlotte has started the game with a lie: she's not Welsh. The 33-year-old business director planned to win over the trust of her fellow contestants by pretending to be Welsh because they have the "one of the most trustworthy accents".
In a piece to camera, Charlotte revealed her secret. She said: "I kind of thought in the past there's only been one person from Wales [in The Traitors], but this year Claudia [Winkleman's] decided to bring two of us here which is so nice.
"Although actually it's a bit of a spanner in the works because I'm not actually from Wales. I'm from London where I am born and bred, I've been putting on a Welsh accent because my mum's from Wales - it's one of the most trustworthy accents, so in a game where we need people to trust each other I need an accent that people can trust. I am now terrified that [Elen] will work this out!"
Leanne is also going into the game with a big secret. Dressed in a Barbie pink suit, the blonde hoped that no one would realise she's not really a nail technician.
She said: "I'm going to say I'm a nail technician, and I work in the salon that's down the road from my house. I'm in that salon all the time. I might as well work there, because my sister-in-law owns the salon with her best friend, so I'm always in. I know a lot about the salon, I do feel like I'm part of the team anyway and that's how I feel like I'll get away with it."
Leanne has a good reason to lie, she's a former soldier. After Harry stole £95k from friend Mollie last year, she's worried people will immediately think she's untrustworthy too.
She said: "Harry won last year. Obviously, he was a soldier, and he bare faced lied his way to the end. I feel like it would put me at a bit of a disadvantage to divulge my previous job because people are automatically going to assume anyone in the military is smart and strategic."
Jack has a secret that even his real life family and friends didn't know about.
He said: "I have secretly trained as an actor. I moved to London when I was 18, moved away from Yorkshire and I didn't really tell too many of my family and friends that that's what I was going to do, because I think there's a bit of a stigma around it in the area that I live in, people think 'oh he wants to go off and chase the acting dream.'
"So, I think I'm used to being put into situations which are hostile and unfamiliar. I think I can kind of play it a little bit dumb, maybe act like the ditzy gardener and landscaper who secretly has his own agenda, and hopefully a couple of acting skills to back that up."
However, the market trader didn't have a chance to spill the beans as he was the first axed from the series. He was one of the three who disembarked the train before they got to The Traitors castle as part of a mission. Will he make a comeback to the series later on?
