"His courage flags," the great voice boomed. "Speak the truth, Earthman. Have you courage to face the gods?"

Stuart stubbornly refused to answer. He had an odd, reasonless impression that this was part of some deep game, that behind the mocking by-play lay a more serious purpose.

The giant leaned forward.
