Thomas Kilbride is a map-obsessed schizophrenic so affected that he rarely leaves the self-imposed bastion of his bedroom. But with a computer program called Whir1360, he travels the world While never so much as stepping out the door. He pores over and memorizes the streets Of the world. He examines every address as well as the people who are frozen in time on his computer screen. Then he sees something that anyone else might have noticed—but has not—in a street view Of downtown New York City: an image in a Window. An image that looks like a woman being murdered. Thomas's brother, Ray, takes care of him, cooking for him, dealing with the outside world on his behalf, and listening to his intricate and increasingly paranoid theories. When Thomas tells Ray what he has seen, Ray humors him with a halfhearted investigation. But Ray soon realizes that he and his brother have stumbled onto a deadly conspiracy. And now they are in the crosshairs. .
