For like the hectic in my blood he rages,
And thou must cure me.

– William Shakespeare

Hamlet, Act 4, Scene 3. Claudius says Hamlet has afflicted him like a disease. The cure is Hamlet’s death. The King sends Hamlet to England with Rosencrantz and Guildenstern and orders in a sealed letter that Hamlet be killed when he arrives there. But Hamlet gets wise to plot me and lives to fight another day.
