The Traitors: Harry and others spill secrets about Claudia and castle

The contestants we spoke to were adamant that they were never told what to say or do by the production team.

“I was never given a script,” says Matt. “I just acted as myself.”

Dr Amos agreed, adding that “the programme makers weren’t trying to catch you out or make you look silly”.

However, they did have the ability to manipulate the game to create drama.

“They might take the traitor on one mission, the faithful on another or they’ll split you up into different teams,” says Harry.

“So they are directing it but they’re not telling us what to say.”

The contestants we spoke to all laughed when asked how much they’ve told people about the show’s outcome.

“You can’t tell anyone,” says Maddy. “I’ve been telling people I’ve been away in Scotland filming an adventure show.”

Dr Amos adds that people were constantly asking him for spoilers but “I kept my lips shut”.

Harry says he broke the rules once and told his girlfriend the outcome of the show. “I was only meant to say I’d left but she saw the ‘banished’ Twitter photo so I had to tell her the truth.”

The contestants we spoke to were all taken aback by the show’s popularity, especially given they weren’t allowed to tell anyone they were filming.

“I didn’t have any expectations of it doing well,” says Charlotte. “It was weird walking into a shop months later and seeing it on the front cover of a magazine.”

But Harry says he’s pleased the show has done so well. “I think it’s brilliant that a show that’s really different to anything else has done so well. It’s a good sign that people want something new and unique.”

Maddy says she hopes the show will continue to grow and even inspire a new generation of spies.

“It’s so important to challenge yourself and this show does that,” she says. “Maybe we’ll inspire a new wave of MI6 agents.”
