The Ansan's laugh jarred out again. "Who or what is inside this ship?" he challenged. "Our great human science has no way of making the air vibrate by itself. Maybe there are ghosts, standing invisible just beside us and whispering in our ears."

"It's demoralizing the crew," said Jansky. "It has to stop."
