Aristotle firmly believed that tragedy in theatre should inspire pity and terror – and who am I to contradict him? One of my plays was performed for the first time at the Cecil Hepworth Playhouse, Walton-on-Thames, in October, with a solid dose of both – if you don’t like it, you can blame Aristotle.

I wasn’t always a playwright. Not so very long ago I was a moderately successful writer with eleven novels under my belt; six crime and five historical espionage. My wife and I were a team: I did the writing and Pat acted as critic – a weak smile and “yes, it’s very good” would send me back to my desk and consign my latest story to the waste paper bin.
