Does the world need another biography of Rupert Murdoch? It depends what it has to say and who has written it.

Bonfire of the Murdochs, by journalist Gabriel Sherman, looks promising. He made his name with an exhaustively researched biography of long-running Fox News head and serial sexual harasser, Roger Ailes. The Loudest Voice in the Room (2014) has 98 pages of endnotes and a team of three fact-checkers. It was made into a series starring Russell Crowe as Ailes. Sherman was also the screenwriter of Donald Trump biopic, The Apprentice, which Trump fought hard to prevent being screened.

Promising credentials, yes, but what does Sherman add to the eight Murdoch biographies already published?

Review: Bonfire of the Murdochs by Gabriel Sherman (Simon & Schuster).

The first was Simon Regan’s business-oriented biography published in 1976. It has been forgotten, but not so George Munster’s A Paper Prince (1985), which laid out Murdoch’s deal-making modus operandi, nor William Shawcross’ 1992 semi-authorised work, which charted Murdoch’s creation of the first global media empire.

Michael Wolff’s The Man Who Owns the News (2008) painted the most vivid portrait of the Australian born media mogul. Flushed with the success of buying The Wall Street Journal, Murdoch agreed to more than 50 hours of interviews with Wolff and opened the doors of his notoriously secretive media empire to the Vanity Fair media columnist.

Wolff did report the Wall Street Journal takeover in detail, but he also retailed a breathtaking amount of industry and family gossip.

One example among many. He writes that Prudence, Murdoch’s daughter from his first marriage, gave him exasperated grooming advice after Murdoch botched a DIY makeover as he tried keeping up with Wendi Deng, his third wife who was the same age as his children.

“Dad, I understand about dyeing the hair and the age thing. Just go somewhere proper. What you need is very light highlights.” But he insists on doing it over the sink because he doesn’t want anybody to know. Well, hello! Look in the mirror. Look at the pictures in the paper. It’s such a hatchet job.

Murdoch’s response? He told her she needed a face lift.

Murdoch’s response to Wolff’s biography was that it needed more than a face lift – it should not have been published with the errors it had. He did not sue for defamation, however. Wolff has since become an even more controversial figure: he is embroiled in suit and counter-suit with Donald and Melania Trump over Wolff’s claims about Trump’s relationship with convicted sex offender Jeffrey Epstein.

The long-running struggle for succession in the Murdoch family famously inspired the brilliantly coruscating fictional television series Succession (2018–2023). Sherman’s is the first biography to deal with its resolution, which happened only last September, when Rupert Murdoch and his eldest son, Lachlan, succeeded in changing the terms of an apparently irrevocable family trust.

The trust had been created when Rupert and his second wife, Anna, separated in 1998. (She died on February 17 this year.) It was her attempt to put a brake on Murdoch’s continual pitting of his children, especially his sons, against each other in the quest to succeed him as head of News Corporation.

It didn’t work. Rupert’s plan for Lachlan to lead the........
