Sweat gleamed on Gurney's brow. "It was ghastly, Langford. In the river—like pieces of dead timber. The current carried them downstream. I was helpless. I—I kept blasting, but I couldn't save them!"

"For your forbearance, your kindliness, thank you, Langford!" a voice said. It was not a spoken voice. It was still and small and remote, and it seemed to come from deep inside Langford's head. Langford stopped advancing; he
