Book excerpt: A newborn’s absent face appears on the back of someone else’s head, a filmmaker goes to gruesome lengths to achieve the silence he’s after for his final scene, and a therapist begins, impossibly, to appear in a troubled patient's room late at night. In these stories of doubt, delusion, and paranoia, no belief, no claim to objectivity, is immune to the distortions of human perception. Here, self-deception is a means of justifying our most inhuman impulses—whether we know it or not.
