George Bernard Shaw and G.K. Chesterton

George Bernard Shaw goaded the already successful essayist and novelist Chesterton into trying his hand at a play, with this 1913 result. The play examines the powers and mysteries of faith, belief, religion, and of course, magic - a mixture that should be familiar from many of his Father Brown stories.

The play's success convinced him to write a couple of other later plays. (Amazon)
