Do we need another biography of Philip Roth? You may well ask. There was Blake Bailey’s 898-page official and generally praised one in 2021. Then there was its baby brother, by a month and 350-odd pages, by Ira Nadel. There’s Roth’s own autobiography – not forgetting the number of times Roth, or more often a character very much like him, appears in his own fiction. Enough already? Well, no, not really.
