No matter how vile your crimes, everyone is entitled to a defence - but there are few more evil criminals than Gloucester mother-of-eight Rosemary West, who butchered ten young women and children. Acclaimed Daily Mail crime writer Stephen Wright interviews West’s former solicitor Leo Goatley, who reveals the horrifying secrets he learned in hundreds of hours with the psychopathic sex killer - including her sordid relationship with her husband and partner in crime Fred, how she was a ‘spitting serpent’ with police and her affair in prison with fellow murderess Myra Hindley.
