“I don’t know,” I answered. “Do you?”

He fidgeted, avoided my eyes, and then rapidly, almost surreptitiously crossed himself.

“No,” he replied. “I know nothing. Some things I have heard⁠—but they tell many tales on these seas.”

He started for the door. Before he reached it he turned. “But this I do know,” he half whispered, “I am damned glad there is no full moon tonight.” And passed out, leaving me staring after him in amazement. What did the Portuguese know?

I bent over the sleeper. On his face was no trace of that unholy mingling of opposites the Dweller stamped upon its victims.
