Professor Renfrew Christie risked death by hanging to spy on the apartheid government’s power stations – using his doctoral thesis as a pretext to gain access to the plants in order to gather intel. He became South Africa’s pioneering nuclear whistleblower. In this week’s episode, he explains how he wrote a confession read aloud in court to provide information on how Cape Town’s nuclear power station could be bombed without loss of human life.

Don’t Shoot the Messenger is produced by Haji Mohamed Dawjee and presented by Rebecca Davis with editing by Tevya Turok Shapiro, original theme music by Bernard Kotze and additional support by Kathryn Kotze.
