Peter Shaffer

Black Comedy is a farce that is played in the dark, as you know, with the lights full on. It's the Chinese convention of reversing light and dark, and exactly where anybody is at any given moment is the play.

If you give me a typewriter and I'm having a good day, I can write a scene that will astonish its readers. That will perhaps make them laugh, perhaps make them cry - that will have some emotional clout to it. It doesn't cost much to do that.
