The mechanic, Frank, scratched his head, the familiar grease on his fingers failing to soothe his agitation. Mr. Peterson had just paid for his repairs – a complete engine overhaul – with a credit card that looked like it was made of gold.

Peterson, a retired teacher, always drove a clunker. Frank’s garage was filled with old cars. Peterson’s was just the oldest of the old. The bill was almost enough to pay Frank's rent and he had never, ever seen Peterson's face give away the slightest emotion.

Frank ran a hand over his tired face. Something about this new information just didn't add up. Why the charade? Why the carefully constructed image of frugality?

He felt a deep churning in his stomach.
