Bagenal stood gaping as shot whizzed by his head. It was his brother-in-law, the traitor Tyrone. And the man had spotted him as well. Fury rose in Henry Bagenal and he strode out into the field to meet the bloody Irish devil. He and Tyrone would fight hand to hand, to the death, he swore to himself. He would have his revenge for Mabel, beautiful child, lost to this wretched land.   THE BALL FROM the musket of the proud Ulster marksman found the very center of Captain Bagenal’s forehead and blew out the back of the Englishman’s skull. Hugh O’Neill saw his brother-in-law fall, and though a great, joyful cry rose in his throat he never missed a step, leading his pikemen onward. But he found himself smiling as he marched, savoring the irony of the moment, for the ball that had smashed open Henry Bagenal’s head had been molded from the melted-down lead that old Lord Burleigh had foolishly sent for the roof of Mabel O’Neill’s proper English castle.
