Kirsty Young's castaway this week is the actress Ruthie Henshall. A West End and Broadway star she has performed in many of the most successful productions of the past twenty years, including Miss Saigon, Les Miserables and Chicago. On stage she has left audiences and reviewers breathless at the dazzling brilliance of her performances. But, off-stage, her life has often been defined more by shade than light.

In this moving interview she talks openly about the abuse she endured as a child and the depression she suffered as an adult. She speaks too of her grief after the death of her "warm and brilliant" sister Noel last year and of the lasting impact Noel has had on her life. Now, Ruthie's happily married with two young daughters but, of the dark days behind her, she says, "I'd spent so many years entertaining and pretending everything was alright, but no matter where you get to it's never enough: you're always looking for the next thing."
