In which book is a character told that first you convince someone that you are their friend, encourage him to confess his sins and when the time is right, talk to him. Tell him what he wants to hear. Gain his trust, then deny him. You refuse to offer the very thing he wants. Forgiveness, freedom, friendship, whatever it is that his heart most desires, you withhold.
