The hero is a young man of high aims and noble purposes: and the writer believes that it is unpardonable to awaken the interest and sympathy of his readers for any other than high-minded and well-meaning characters. But he is not faultless; he makes some grave mistakes, even while he has high aims. The most important lesson in morals to be derived from his experience is that it is unwise and dangerous for young people to conceal their actions from their parents and friends; and that men and women who seek concealment "choose darkness because their deeds are evil."
