"I know."

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.

"Come along, Rip," he said. "Why, you are cold and miserable to-night!
Must I carry you then?"

He picked the dog up, turned out the light, and walked slowly into his
bedroom.
