How I was abused by my paedophile sister: At 13, Harriet was plied with drugs and made to perform grotesque incestuous acts. Now as her abuser is found guilty, she bravely tells her story and says: 'I've got my life back'

Harriet Richards was barely more than a child when the abuse began; when she was plied with drugs and alcohol, then made to perform sex acts with a woman.
