You say your life is your own. But can you dare to ignore the chance that you are taking part in a gigantic drama under the orders of a divine Producer? Your cue may not come till the end of the play--it may be totally unimportant, a mere walking-on part, but upon it may hang the issues of the play if you do not give the cue to another player. The whole edifice may crumple. You as you, may not matter to anyone in the world, but you as a person in a particular place may matter unimaginably.
Agatha Christie, The Mysterious Mr. Quin
