Sue Lawley's castaway this week is the novelist Alice Thomas Ellis.

A devout and traditional Catholic, she didn't begin writing until she was 42. The Sin Eater, that first novel, was her reaction to the changes in the Catholic Church after Vatican Two and channelled her anger at what she saw as the excesses of the 1960s. She's a woman of apparent contradictions. She wanted to be a nun, but fell in love and became a mother of seven instead. She's deeply religious but believes in ghosts and the supernatural and although her books are often triggered by anger, they are frequently tender and full of humour.
