It has come to my knowledge, Señor Don Sancho Panza, that certain enemies of mine and of the island are about to make a furious attack upon it some night, I know not when. It behoves you to be on the alert and keep watch, that they surprise you not. I also know by trustworthy spies that four persons have entered the town in disguise in order to take your life, because they stand in dread of your great capacity; keep your eyes open and take heed who approaches you to address you, and eat nothing that is presented to you. I will take care to send you aid if you find yourself in difficulty, but in all things you will act as may be expected of your judgment. From this place, the Sixteenth of August, at four in the morning.

Your friend,

The Duke
