“What do you know of sacrifice? Need I tell you of York's dead . . . of Sandal Castle? My brother did survive the battle, his first. He was seventeen and he entreated them to spare his life. They cut his throat. Their heads were then impaled on York's Micklegate Bar to please the House of Lancaster, to please a harlot and a madman. She had my father's head crowned with straw and she left a spike between the two. . . . That one, she said, was for York's other son.”
