‘Never announce you are a Knight, simply behave as one. You are better than no one, and no one is better than you.’When Sir Thomas Lemuel Hawke was a boy, his grandfather taught him how to be a knight. Now, on the eve of a battle from which he fears he may not return, Sir Thomas writes a letter to his children so that he may pass on all his hard-won lessons, deepest aspirations and most instructive failures. Full of adventure and wit, the letter provides a guide for living a good and noble life – a reminder that without a little agony none of us would bother to learn a thing; that we must work together as brothers or perish together as fools; that a friend loves you because you are true to yourself, not because you agree with him. And, most importantly, it shows that there is no obstacle that enough love cannot move.
