Rafe asks him, could the king's freedom be obtained, sir, with more economy of means? Less bloodshed? Look, he says: once you have exhausted the process of negotiation and compromise, one you have fixed on the destruction of an enemy, that destruction must be swift and it must be perfect. Before you even glance in his direction, you should have his name on a warrant, the ports blocked, his wife and friends bought, his heir under your protection, his money in your strong room and his dog running to your whistle.
