After my comments about the importance of reading widely (and Allan Little's impassioned guidance on the same theme), Alan McGuinness asked me to recommend my favourite novels about journalists and journalism. You know about Scoop by Evelyn Waugh. I also recommend Towards the End of the Morning by Michael Frayn, The Quiet American by Graham Greene and Yellow Dog by Martin Amis. Of course, journalists should not restrict themselves to fiction about journalists.
So, in the hope that others will add many more and better suggestions, here is a very small selection of novels I have enjoyed, from which I have learned, and which I think you might appreciate: Catch 22 by Joseph Heller, Lucky Jim by Kingsley Amis, We Need to Talk about Kevin by Lionel Shriver, The Secret History by Donna Tartt, Norwegian Wood by Haruki Murakami, The Mysteries of Pittsburgh by Michael Chabon, Money by Martin Amis, The Rotters' Club by Jonathan Coe .
