Suranne Jones has promised that Doctor Foster will be just as nail-biting the second time around when the jaw-dropping drama returns to BBC1 later this year.

Suranne, who gave birth to her first child last month, revealed that after reading the scripts for the show’s second series, she was left stunned.

“I’ve read episode one and… it’s pretty good!” she said. “My reaction was, ‘Oh My God, are you serious?’ So yeah… it’s good!”

Suranne, 37, added that series two is a “separate story” from its predecessor, and will follow the “trauma” of a divorce fall-out.

“That had only just been touched on [in the first series] – so yeah, we start with the trauma and what happens in the period after,” she added.

Suranne’s comments, in the Daily Express, come after she admitted to being initially reluctant to reprise her role as the heroine, who thrust brutal revenge on her cheating husband Simon (Bertie Carvel).

The former Coronation Street star explained: “[It was] because my story had finished, but then when they told me what they wanted to do with it, I felt that nothing had been done on television like it.”

Suranne, currently on TV in Scott & Bailey, recently confirmed filming for Doctor Jones’ next chapter will begin this September.

“Hopefully my baby brain will have gone by then – because learning lines is hard enough… but I’ve been getting to sleep and then waking up at 2.00am!” she revealed.

Doctor Foster is nominated for Best Short Series at this year’s Television BAFTA Awards in London against This Is England ’90, London Spy and The Enfield Haunting.

Suranne is also nominated in the Best Actress category against Ruth Madeley (Don’t take My Baby), Claire Foy (Wolf Hall) and Sheridan Smith (The C Word).
