DUKE VINCENTIO: The contents of this is the return of the duke: you shall anon over-read it at your pleasure; where you shall find, within these two days he will be here. This is a thing that Angelo knows not; for he this very day receives letters of strange tenor; perchance of the duke's death; perchance entering into some monastery; but, by chance, nothing of what is writ. Look, the unfolding star calls up the shepherd. Put not yourself into amazement how these things should be: all difficulties are but easy when they are known. Call your executioner, and off with Barnardine's head: I will give him a present shrift and advise him for a better place. Yet you are amazed; but this shall absolutely resolve you. Come away; it is almost clear dawn.
