The tyrant must never sleep. He must vary the locations and times. He never sleeps in his palaces. He moves from secret bed to secret bed. Sleep and a fixed routine are among the few luxuries denied him. It is too dangerous to be predictable, and whenever he shuts his eyes, the nation drifts. His iron grip slackens. Plots congeal in the shadows. For those hours he must trust someone, and nothing is more dangerous to the tyrant than trust.
