When Arthur rises the next morning, he is deeply troubled. He sits at home for a while and then goes riding, and all the time his mind is turning over the situation with Hetty. He feels guilty about deceiving Adam and about leading Hetty to hope for marriage, but he dodges his own guilt, unwilling to accuse himself of wrongdoing. He doesn't want to cause Hetty pain by writing the letter, but he decides that he must clear the way for Adam to win Hetty's love. He writes the letter and gives it to Adam with the injunction that Adam must follow his conscience in deciding whether or not to deliver it to Hetty. Arthur then leaves to join his regiment, which is stationed at Windsor.
