"Open the door."

The owner of the place did so. Dan peered down into the darkness and was about to turn away, when he thought he heard voices. He listened intently.

"Who is down there?" he asked of the proprietor.

"No one."

"Get a light and lead the way."

The proprietor did so, his face working convulsively as he sought to control his rage.

Leading the way across the cellar, the fellow threw open a door. A great wave of damp, smoky air smote the newcomers in the face.

"So that's the game, is it?" demanded Dan triumphantly. There were the others of the missing men, enjoying themselves immensely. They were laughing and joking.

"Attention!" commanded Davis.

A loud laugh greeted his order.
