He turned and opened his arms in a wide gesture. "Do I look rich?" he said. "Don't know," said the girl. "Maybe, maybe not. Maybe you'll get rich. I have a very special service for rich people..." "Oh yes?" said Ford, intrigued but careful. "And what's that?" "I tell them it's OK to be rich."

Ford stopped and peered into the dark doorway. "You what?" he said. The girl laughed and stepped forward a little out of the shadow. She was tall, and had that kind of self-possessed shyness which is a great trick if you can do it. "It's my big number," she said. "I have a Master's degree in Social Economics and can be very convincing. People love it. Especially in this city."
