Investigative journalist Patrick Radden Keefe has made a career out of chasing the kinds of stories that most people would be wise to leave alone. The New Yorker writer is drawn to powerful institutions and the people at their heart – from the Sackler dynasty, whose pharmaceutical company created the opioid painkiller OxyContin in Empire of Pain, to the legacy of the Troubles in Northern Ireland in Say Nothing. His latest book, London Falling, delves into the story of 19-year-old Briton Zac Brettler, who had been living a double life, pretending to be the son of a Russian oligarch, before he mysteriously fell to his death from a luxury apartment building in London. Radden Keefe, the so-called “journalist’s journalist”, joins us to discuss London Falling, the ethics of true-crime reporting, and a reporter’s need for scepticism. Plus, we get our own scoop on what he might tackle next – and why it could bring him to Australia. Today’s episode is hosted by Spectrum editor Melanie Kembrey.
