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?
