Billie Piper has admitted that she couldn’t help but agree to take the part in her new TV drama after reading the book, The Intimate Adventures of a London Call Girl, that the show was based on.

Billie said:

“It was Belle, the person portrayed in the book that drew me to the project. I found her absolutely fascinating and some of her ideas quite romantic plus I liked her style of writing. I thought she was funny, witty, sharp and intelligent and I liked the idea of playing her.

“This is such a taboo subject, no one really ever speaks about it except the horror stories about the nature of the work. It was certainly a very different story to every other one I’d heard about prostitution.”
