They regarded each other almost uneasily. Then Valentine added, with a short laugh:
"I can't have drawn it thoroughly over the door when Wade went away."
"I suppose not. Well, good-night, Val."
"Good-night. Shall we sit again tomorrow?"
"Yes; I vote we do."
Valentine let his friend out. As he shut the front door, he said to himself:
"I am positive I did draw the curtain thoroughly."
He went back into the tentroom and glanced again at the curtain.
"Yes; I am positive."
After an instant of puzzled wonder, he seemed to put the matter deliberately from him.
