NEW drama Undeniable wonders what you would do, 23 years after the unsolved murder of your mother, when you recognise the murderer.

In Chris Lang’s thriller, Claire Goose plays Jane Phillips, who was seven at the time of the attack which she survived but in which her mother died. The killer was never found.

Now Jane is pregnant with her second child, and as she attends an ante-natal clinic, she claps eyes on the man she is adamant is responsible for her mother’s death. But Andrew Rawlins (Peter Firth, late of Spooks) is in fact a well-respected consultant oncologist and Jane has wrongly identified suspects before.

As Andrew is suspended and inquiries get under way, inconsistencies crop up in both Andrew and Jane’s testimonies, and the strain of the accusation is pushing both their families to breaking point.

Goose, whose past TV roles include Casualty and Waking The Dead, admits it was hard-going at times filming the emotional scenes for the new drama.

“I seem to cry a lot, even in scenes when I’m not talking I tend to cry because I find all the words overwhelming. You really feel for her because it has consumed her life,” she says.

“A lot of the evocative scenes were filmed within Jane’s house. That really helped me as it kept the focus in that one place. During filming, I kept saying to Felix [Scott, who plays husband Rob], ‘I’m not going to cry in this scene’, cut to me just welling up.”

However, she does equate all that emotion to a fantastic script.

“It was just the most amazing script,”

Goose says. “I remember the first time I read it I was at home. I finished and turned to my husband and said, ‘it’s such a great part’.

“Straight away, I had a massive emotional connection with the character. I thought, ‘I get her’ and I knew exactly how I would want to approach playing her.

“It is not just one person that is affected, it is everyone,” she says. “Some relationships break down and some relationships become stronger because of it.

“By setting the drama within a family unit, I think a lot of people will identify with the characters and how it might be if those things happened to them.”
