Writing about his daughter and the anorexia that killed her
Debbie Barham was one of Britain's greatest comedy writers - at the age of just 14 she sold her first joke to the BBC under the male sounding pseudonym of D.A Barham. From 16 she was regularly writing for television, radio and print but she lied about her age for fear it might put people off.
She wrote for many famous names including Ned Sherrin, Graham Norton, Clive Anderson and Douglas Adams but the brilliance of her comedy ran in tandem with a long and devastating plunge into anorexia. She died at the age of 26, weighing just four and a half stone.
Jenni is joined by Debbie's father Peter, who nursed her through part of her illness and who's written a book, 'The Invisible Girl' in tribute to his daughter.
