"The tall man tilted his glass. 'You've been to Coeurville, so you've learned that Peter Nolan never lived there. You also know that you've been behaving -- oddly -- of late. And from the handkerchief around your hand, I should judge you know about that, too. With this information what can I tell you?' 'Who am I?' The heat was beginning again. 'You're nobody,' the tall man said. 'You're nobody at all.' 'Stop it, Walter.' Who is this watch I'm wearing? Ask me that. Who is the refrigerator in the kitchen? Don't you understand?' The man's eyes glinted briefly. 'You're a machine, Pete'.
