Let us leave the boys in the cellar and see what Chot and Truem were doing in the passageway, as well as the cause of the revolver shot which had been audible to those above.

After closing the massive door and fastening it securely, Chot and Truem waited silently in the passageway for the developments they were sure would not be long in coming.

After a few minutes they heard sudden footsteps in the room beyond the door, then some one began rattling the door in a strenuous effort to get out. Of course, this was the fourth member of the smuggler quartet, who had escaped down the trap when Pod switched on the lights. But Chot and Truem, not knowing how their chums were faring in the basement, thought the entire band of smugglers was making an effort to escape.

So when the door began to tremble, Chot called in a loud tone:

“Stop, or I’ll shoot you through the door!”

Evidently surprised at finding enemies in the passageway, as well as in the basement, the man inside ceased his efforts. But he said nothing, and after a short pause, Chot said again:

“Do you surrender?”

“Yes,” came the voice from within.

“Well, we’re going to open the door, and you’re to come through with your hands in the air—and empty! Do you understand?”

“Yes.”
