One of Australia’s greatest biographers has turned his spotlight onto his own family and discovered some dark and difficult secrets.

Marr’s great-great-grandfather was a professional killer of Aboriginals in the Native Police, and he chronicles that and the broader picture of an earlier, brutal Australia in his latest book Killing for Country: A Family Story.

Marr joins us to talk about writing the book, but also about his life and how he became such a forensic, unflinching biographer.

Guest: David Marr, writer, essayist
