"I guess there are psychological reasons for [writing mystery novels] which I don't entirely understand, but I love structure in the novel. It's not surprising that overwhelmingly my favorite novelist is Jane Austen -- structure is tremendously important to her. I love the idea of bringing order out of disorder, which is what the mystery is about. I like the way in which it affirms the sanctity of human life and exorcises irrational guilts.
