Brecht's famous parable, written in exile in 1939-41, shows that in an unjust society good can only survive by means of evil. In it, the gods come to earth in search of enough good people to justify their existence. They find Shen Teh, a good-hearted but penniless prostitute, and make her a gift that enables her to set up her own business. But her goodness brings ruin and she must disguise herself as a man in order to muster sufficient ruthlessness to survive. One of the greatest poets and dramatists of our century (Observer)
