J.K. Rowling is one of the most successful writers in the world, but the one person she wanted to see her success never got to — her mother. “She never knew about Harry Potter – I started writing it six months before she died, so that is painful. I wish she’d known,” she said during an interview with BBC Radio 4. She discussed her mother’s death, multiple sclerosis, rugby, and more when she guest edited an edition of “Woman’s Hour.”
