Sorry about that previous post - I should have checked that someone else posted that SCMP Interview before me.
Has anyone read or heard of a book called "the billionaire who wasn't" by Conor O'Cleary? It's a biography of Robert Millers former business partner Chuck Feeney. It's got some interesting stuff about Bob Miller and the family, although most of it isn't flattering as the Millers in the book are set up as foils to the Feeneys, mostly by showing Feeneys philanthropy and modesty in contrast to the Millers extravagance and social ambitions, or at least that's how the author portrayed it. It also goes into detail about what brought Chuck and Bob's partnership to an end in the 1990s.
