Just a roaring for an instant—and a big white mushroom shooting straight up into the sky. Then, slowly, the mushroom decayed and fell back, and an awful stillness settled down over the river. The stillness was broken by a shrill cry from Pigtail Anne. "It was a flying saucer! Jimmy, we've seen one! We've seen one! We've—" "Shut your mouth, Pigtail!" Jimmy shaded his eyes and stared out across the river, his chest a throbbing ache. He was still staring when a door creaked behind him. Jimmy trembled.
