part two introduces margarita, the master's mistress, who refuses to despair of her lover or his work. she is invited to the devil's midnight ball, where satan (woland) offers her the chance to become a witch with supernatural powers. this coincides with the night of good friday: the master's novel also deals with this same spring full moon when christ's fate is sealed by pontius pilate and he is crucified in jerusalem. all three events in the novel are linked by this.
