"You stay there a minute," Jasper ordered, as he closed the door and turned back into the room. Lighting a lamp, he was astonished to find that it was near midnight. It took him but a few moments to dress, and then he again threw open the door and stepped out into the night.

MYSTERY

By the light streaming through the doorway Jasper could see that Betty's face was very pale. She was greatly agitated as well, and her teeth chattered as she spoke.

"You have been running hard," Jasper remarked. "You had better come in and rest awhile."

"No, no," the girl protested. "Don't let us wait a minute. We must find Mr. David!"

"Are you sure he isn't home?" Jasper asked.

"Yes, I am sure he isn't there."

"But he may have slipped in and you didn't hear him."

"No, no, he couldn't have done it. I was listening and watching every minute for him to come back. I am certain I would have seen him."
