But just as he is trying to get medical attention for this supposedly lost girl and get her home, he has a seizure, which immediately brings the reader to part 2, "Brain Work." It turns out the seizure is due to a cerebrovascular event coupled with a brain tumor. Because of ensuing amnesia, Nick has to try to figure out what he's been working on, what he has found, and what it all means. But he can no longer recall the code he used to take his notes. In an instant, Nick is transformed from a typical hardboiled detective "superhero" into an invalid, struggling to exercise his body, especially his damaged brain. But interestingly, Nick finds that his symptoms bring some new strengths. He certainly seems like a nicer person—which the reader can infer through the book's piecemeal revelation of his past. He begins a new relationship with his son—he had been distant, like his own father was, and a divorce didn't help—and discovers ways of being more open in his interactions with others.
