By George - we stand corrected! Following our item last Friday about author George Adams and his forthcoming opus, The Great Hongkong Sex Novel, which is soon to invade the bookshops (and our senses?), the writer called to point out that, contrary to what we had implied, his creative juices also flowed nicely when he was living in other parts of the world. ''I will have you know,'' quipped Adams, ''that I won a national prize for my German writing in Switzerland''. He also tells us that he is soon to be ''anthologised'' (which sounds pretty painful). ''I will soon sign a deal with an American publisher for a forthcoming book of writing about Hongkong,'' he explained. ''It will also feature the work of Andre Malraux, Jan Morris, Somerset Maugham, John Le Carre and W. H. Auden''. Adams adds, in parting: ''Life's grand, ain't it?'' For novelists? We should say so, matey.
