Former detective chief inspector Peter Fox served for 36 years at the coalface of the NSW Police Force. He rose to national prominence in 2012 when he broke rank to speak about the concealment of child sexual abuse. Four days later, his decision to speak out helped trigger prime minister Julia Gillard's historic decision to establish the Royal Commission into Institutional Responses to Child Sexual Abuse. It also spurred a backlash from those uncomfortable with the truth. His memoir Walking Towards Thunder details his unforgettable story.
