“Lies can be wrung out of a witness as easily as truth. Yes, after a few hours with the Enquiry’s . . . instruments, I am sure she will be willing to swear that she had swallowed an antidote, or indeed that she had flown to the moon if that would make the pain stop. But, here and now, you can see she is telling the truth. There was no betrayal. There was no poison. There was no murder.”

“Lyra learns to her great cost that fantasy isn’t enough. She has been lying all her life, telling stories to people, making up fantasies, and suddenly she comes to a point where that’s not enough. All she can do is tell the truth. She tells the truth about her childhood, about the experiences she had in Oxford, and that is what saves her. True experience, not fantasy - reality, not lies - is what saves us in the end.”

“She murdered for her truth, and they had died for theirs.”

“To tell the truth, this was one of the few cases in which she had not told him just what she was thinking. Usually, she let him know whatever thoughts happened to come to her, and indeed he never took it amiss if she let slip a word that might pain him, because when all was said and done that was the price one paid for sincerity.”

“Cathy did not forget her lies, and she developed the most effective method of lying. She stayed close enough to the truth so that one could never be sure. She knew two other methods also––either to interlard her lies with truth or to tell a truth as though it were a lie. If one is accused of a lie and it turns out to be the truth, there is a backlog that will last a long time and protect a number of untruths.”

“in a rash moment he decided to lie his way to the truth. If he wasn't mistaken, Ellen Magnusson had had very little experience with the police. She would assume that they searched for the truth by being honest themselves. She was the one who would lie, not the police.”
