Suranne Jones has revealed she met with a bereavement counsellor to get her performance right on ghostly new series The Secret Of Crickley Hall.
The former Corrie actress and Miranda star Tom Ellis play parents Eve and Gabe, who move to a mysterious new home in the hope that a change of scene will help them recover from the mysterious disappearance of their young son Cam.
Suranne said of her meeting with the grief expert: "I told him Eve's story, and then I wanted him to treat me as she would be treated. I think that was important, just to understand what the process would have been through the guilt and the stages."
Portraying a mother's grief hasn't been the only challenge for Suranne, with the show's special effects not added until after filming wrapped.
"The difficult thing is having to react to an empty staircase where I may or may not have seen a ghost," she said.
Suranne also admitted the show's spookiness was felt on set during shooting.
"There was a supporting artist, who is a medium or a spiritualist, I can't remember, and she came into the house and went up to the back bedroom, which happens to be Eve and Gabe's, and she said there was an angry male presence there," she said.
"And a make-up artist said she'd heard her name, but then she turned around and there was no one there."
:: The Secret Of Crickley Hall begins on BBC One on Sunday, November 18.
