In July 2022 Campbell interviewed journalist Alex Renton on Different and revealed he had witnessed and experienced abuse at his school The Edinburgh Academy. Campbell wrote an article for the Mirror on the same day as the podcasts release. The revelations made headlines all over the world and increased pressure on the Scottish prosecution services to extradite one of the alleged abusers from South Africa, referred to as Edgar in the podcast and press because of a ruling on anonymity by the on-going Scottish Child Abuse Inquiry. ‘Edgar’ features heavily including Day 261 of the inquiry, in which he is referred to as ‘CDZ’. After the podcast was released dozens more men came forward and the police opened an investigation solely relating to the Edinburgh Academy, Operation Tree Frog. Renton reported that because of the publicity ex-pupils of Edinburgh Academy had named 17 other staff members, employed between the 1950s and 1980s, as physical and sexual abusers.
