Guardian Australia reporter David Marr is the author of a new Quarterly Essay, The Prince: Faith, Abuse and George Pell. It is an investigation into Pell's rise to power, his politics, and how he has shaped the Catholic church in Australia in the era of the child abuse scandal.

He's a winner of four Walkley awards for journalism and the author of biographies of Sir Garfield Barwick, Patrick White, John Howard, Kevin Rudd and Tony Abbott.

David is also an expert on Australia's relationship with asylum seekers, and co-wrote, with Marian Wilkinson, an account of the Tampa affair called Dark Victory.
