Writers have opinions - that, in part, is why they write. Therefore they have strong likes and dislikes.

For a startling period of my life, I reported the Troubles in Ireland for the BBC. I lived in Dublin and was called out to all sorts of incidents that, if taken together, add up to a war - bombings, assassinations, riots, shootings, robberies, jailbreaks, kidnappings, and sieges.

First a piece of Irish wisdom: you should always listen to a bookie. For they have a saying, 'Money tells a good story,' and somewhere in their odds is a kind of science-fiction existentialism that decrees that we, the people, know everything. In other words, betting patterns often make for good, unconscious soothsaying.

As an arts journalist in London, working mainly for the BBC, I interviewed hundreds if not thousands of authors. From them I gleaned a great deal of passing instruction in writing and I observed one fascinating detail: no two writers approach their work - physically - in the same way.
