"Had it repeated," he panted. "Williams is storming at you; says there's no mistake, and you'd best get on."

He thrust the second message up as he spoke.

His lips moved as if he were calculating chances, and his eyes suddenly quailed as if he saw death at the end of the calculation. I was watching him with considerable curiosity. I ventured to ask him what was the matter, and what he was going to do.

"I'm going to obey," he said curtly.
