Peter Hitchens at his Mail blog is urging his admirers to read Malcolm Bradbury's 'The History Man' - a thinly fictionalised eye-witness account of the cultural revolution at an early 70s university.
One writer who saw it all coming was the thriller writer James Barlow, who attacked the sixties ethos pretty much from the word go - in fact he was attacking it in his first (1956) novel The Protagonists, when it was still struggling to be born.
He wrote pretty much a novel a year through the 60s - The Patriots is probably his best. While I wouldn't call him a great writer, I enjoy his work. Favourite targets of attack were trendy bishops, TV talking heads and chat show hosts - people whose currency was words. I'm sure as an author he appreciated the irony.
He emigrated to New Zealand in the early 70s, leaving with "Goodbye England" - his disgusted (non-fiction) valediction, featuring a much-mocked paragraph about topless girls walking through London with dust and bus-tickets adhering to their mammaries. I must get hold of a copy, as I've never read it.
There's very little about him on the Web and no site devoted to him. If anyone has any information about him I'd love to hear it.
