On the one hand, this is a twisty-turny noir tale, complete with mistaken identity, possibly corrupt police, and shadowy mob-style figures. Our narrator is a psychiatrist Dr. David Manne, is called in to give an opinion on temporarily committing a patient. From there things get strange. The other side of this book could range anywhere from someone unstuck in time to an examination of the question of what it means to be sane. The craft of this book is enviable – short sentences, uncovering just enough information to keep the page turning, but the possibilities and questions provoke deep, reflective thought.
