" ...Heracles was strangely silent. What is he thinking? / Geryon wondered. / Geryon watched prehistoric rocks move past the car and thought about thoughts. / Even when they were lovers / he had never known what Herakles was thinking. Once in a while he would say, / Penny for your thoughts! / and it always turned out to be some odd thing like a bumper sticker or a dish / he'd eaten in a Chinese restaurant years ago. / What Geryon was thinking Herakles never asked. In the space between them / developed a dangerous cloud. "
