‘We will have peace,’ said Théoden at last thickly and with an effort. Several of the Riders cried out gladly. Théoden held up his hand. ‘Yes, we will have peace,’ he said, now in a clear voice, ‘we will have peace, when you and all your works have perished – and the works of your dark master to whom you would deliver us. You are a liar, Saruman, and a corrupter of men’s hearts. You hold out your hand to me, and I perceive only a finger of the claw of Mordor. Cruel and cold! Even if your war on me was just – as it was not, for were you ten times as wise you would have no right to rule me and mine for your own profit as you desired – even so, what will you say of your torches in Westfold and the children that lie dead there? And they hewed Háma’s body before the gates of the Hornburg, after he was dead. When you hang from a gibbet at your window for the sport of your own crows, I will have peace with you and Orthanc. So much for the House of Eorl. A lesser son of great sires am I, but I do not need to lick your fingers. Turn elsewhither. But I fear your voice has lost its charm.’
