" The story you’ve just been listening to is called Falsehood Exposed, or The Tale of a Grandmother. It is a story which took place under the reigning dynasty, on this very day of this very month of this very year on this very spot and at this very hour. How can Grannie “with one mouth tell a double tale”? Ah, how indeed! Our tale puts forth two tails. Which tail to wag? Wig-wag. But for the time being we do not inquire which tale is false, which true. Our story turns rather to those people in the party who were admiring the lanterns and watching the play… Just give these two kinsfolk a chance to drink a cup of wine and watch a scene or two more of the play, Grannie, and then you can get on with your Exposure of Falsehood – dynasty by dynasty. "
